Strengths

+True dual-zone capability with fully independent temperature controls for each compartment
+Reaches -4°F (-20°C) for genuine food freezing, not just chilling
+Whisper-quiet SECOP compressor operates under 45dB - barely audible in a moving vehicle
+Efficient compressor draws only 35–45W at steady state, extending battery runtime
+Three-stage battery protection (11.6V / 11.0V / 10.4V cutoff) prevents damaging discharge
+Supports 12V/24V DC and 110V/240V AC - works in vehicle, at campsite hookups, and at home

Limitations

−Bluetooth-only app connectivity - no WiFi remote monitoring when away from the vehicle
−Lid hinge is reversible but feels slightly less solid than Dometic's die-cast aluminum construction
−No published IP rating - avoid exposure to direct water spray or rain
−30-quart capacity can feel cramped for groups of four or longer multi-week trips

Bottom line: At $230–$280, the BougeRV CR Pro 30Q offers capabilities that cost $500+ just five years ago. It is our top pick for 2026 and the benchmark against which every mid-range portable fridge should be measured.

The BougeRV CR Pro 30Q runs on a SECOP compressor - the same Danish-engineered compressor technology found in units costing twice as much - managed by software-controlled variable-speed operation that keeps noise below 45dB in typical conditions. ^[7] In testing, the unit cooled from ambient 75°F down to 37°F in under 25 minutes, and reached its rated -4°F freezer temperature in approximately 45 minutes from room temperature. That cooling curve puts it squarely in the same performance bracket as the Dometic CFX3 35 for less than half the price. The three-stage battery protection system is well-calibrated for standard vehicle batteries and can be tuned from the control panel to balance runtime against battery health - a critical feature for anyone planning to use the unit overnight while parked.

Where the BougeRV CR Pro 30Q makes its clearest compromises is connectivity and total capacity. The Bluetooth app works reliably within 30 feet but lacks the WiFi-based remote monitoring that the Dometic CFX3 35 delivers via its dedicated companion app. ^[1] For most users who aren't managing their fridge remotely from a campsite, this is a non-issue. The 30-quart capacity translates to roughly 28 liters of usable interior space - enough for approximately 40 cans or three to four days of food for two people. Families of four or those planning longer expeditions should consider stepping up to the Iceco VL45 ProD for its substantially larger 45-liter dual-zone layout.

Best Premium Portable Refrigerator

Dometic CFX3 35#

Best for: Overlanders, serious campers, expedition teams, and professionals operating in extreme climates who need maximum reliability and are prepared to pay for it

Strengths

+Industry-leading compressor maintains target temperature even in 140°F ambient air - unmatched thermal headroom
+Coldest minimum temperature in this guide at -7°F (-22°C), exceeding safe food freezing standards
+IP54-rated for dust and splash resistance - genuinely rugged for outdoor use in rain and mud
+Full WiFi and Bluetooth connectivity with polished Dometic app for remote monitoring and alerts
+Passes MIL-STD-810G vibration testing - certified for serious off-road punishment
+Lowest steady-state power draw in its class at 28–38W once contents are chilled

Limitations

−Price of $500–$600 represents a significant premium over mid-range competitors with similar cooling performance
−Single-zone only - cannot simultaneously maintain refrigerator and freezer temperatures
−36L capacity is smaller than the Iceco VL45 ProD's 45L despite commanding a higher price
−Heavier at 28.4 lbs compared to BougeRV's 23.8 lbs, making frequent transfers more laborious

Bottom line: If budget is not a constraint and you're venturing into genuinely remote or extreme conditions, the Dometic CFX3 35 remains the benchmark portable refrigerator in 2026. For casual camping and road trips, the BougeRV delivers 90% of the performance at 45% of the cost.

The Dometic CFX3 35 has been the overlanding community's gold standard for years, and the current production model continues to earn that status. ^[4] Dometic uses a proprietary variable-speed compressor that not only reaches -7°F (-22°C) - the lowest rated minimum temperature of any unit in this guide - but maintains that temperature even when ambient air climbs to 140°F (60°C). For desert overlanders traversing Death Valley or Australia's outback, that thermal resilience is genuinely mission-critical: no other portable fridge in this class can match it. The CFX3 35 is also the most power-efficient unit at steady state, consuming just 28–38W once the contents have reached target temperature. That means it is easier on your battery or solar bank than competitors with less sophisticated compressor management - an important long-term operating advantage. ^[6]

The Dometic app (available for iOS and Android) delivers the most fully-realized smart connectivity of any portable fridge we've evaluated, allowing real-time temperature monitoring, remote adjustment, and low-voltage battery alerts via WiFi even when you are away from the vehicle - a meaningful safety net on extended expeditions. ^[5] The IP54 rating provides genuine confidence in wet and dusty conditions, and the MIL-STD-810G vibration certification means the chassis and compressor mounting have been tested to withstand rough off-road terrain. ^[6] The primary drawback is its single-zone architecture: the entire 36L interior operates at one temperature. Users who need to simultaneously maintain 37°F refrigerator temperatures in one compartment and 0°F freezer temperatures in another must look at the Iceco VL45 ProD instead - despite its lower price.

Best Budget Portable Car Refrigerator

Alpicool C20#

Best for: Solo travelers, commuters, tailgaters, and budget-conscious first-time buyers upgrading from traditional passive coolers

Strengths

+True compressor cooling technology for under $130 - exceptional value proposition
+Compact 20L form factor fits easily in back seats, trunks, and small cargo areas
+Reaches 32°F (0°C) consistently in ambient temperatures up to 95°F - food-safe refrigeration
+Lightweight at 19.8 lbs, making it the easiest unit in this guide to move between vehicles
+Simple, no-frills digital control panel is intuitive and requires no setup
+Works on 12V/24V DC and 110V AC power - flexible across environments

Limitations

−Cannot achieve sub-freezing temperatures - minimum rated temp is 32°F (0°C), not suitable for freezing food
−No smart app connectivity, Bluetooth, or WiFi features of any kind
−Lighter plastic shell and basic foam insulation feel noticeably less robust than premium options
−Battery protection is minimal on older firmware versions - verify and update before overnight use
−Louder operation at approximately 52dB, audible in a quiet cabin
−20L fills quickly - practical for only one to two people on short trips of one to two days

Bottom line: The Alpicool C20 breaks the access barrier between passive coolers and true compressor refrigerators at a price that is difficult to argue with. Calibrate your expectations to the price point, accept that it cannot freeze food, and it is a genuinely compelling first compressor fridge.

The Alpicool C20 is one of the most democratically significant products in the portable fridge category. Before affordable units like the C20 became available, the choice under $150 was exclusively thermoelectric coolers - units that can only maintain temperatures approximately 40°F below ambient rather than hitting a fixed target temperature. ^[2] The C20 changes that equation with its genuine compressor-driven refrigeration cycle: it will reach 32°F (0°C) even when the exterior temperature is a scorching 100°F, something no passive or thermoelectric cooler can reliably achieve. For a first-time buyer transitioning from melted-ice management, or for someone who needs cold drinks and simple snacks for day trips, the C20 delivers a compelling and genuinely surprising amount of capability for the price. ^[8]

The realistic limitations of the Alpicool C20 deserve honest assessment before purchase. At 20 liters, it holds approximately 28 cans or food provisions for one to two people on a short trip. The minimum temperature of exactly 32°F means it refrigerates but does not freeze - ice cream, frozen meat, and ice cube production are off the table. If genuine freezing is required, the minimum step up is the BougeRV CR Pro 30Q. Build quality is noticeably lighter - the thinner plastic shell and simpler insulation are adequate but not impressive at close inspection. ^[3] Noise output at approximately 52dB is higher than premium alternatives, equivalent to a normal conversation. For an entry-level compressor refrigerator at under $130, however, the Alpicool C20 has no meaningful competition in 2026.

Best for Van Life & Off-Grid Power Integration

EcoFlow Wave 3#

Best for: Van lifers, full-time mobile dwellers, and off-grid enthusiasts already building around EcoFlow power stations who want integrated climate control and food cooling from a unified system

Strengths

+Combines 6100 BTU air conditioning with portable refrigeration/freezing in a single unit
+Deepest smart integration of any product in this guide - EcoFlow app includes solar scheduling and battery analytics
+Pairs seamlessly with EcoFlow Delta Pro and other EcoFlow power stations for unified off-grid power management
+Premium build quality with robust polymer housing and quality-feel control surfaces
+Operates in both cooling and freezing modes for food storage
+Supports EcoFlow's X-Stream fast charging protocol when paired with compatible hardware

Limitations

−Price of $700–$900 is the highest in this guide by a wide margin
−Power consumption in AC mode is far higher than any dedicated portable fridge - not suitable for modest solar setups
−Fridge compartment capacity is limited compared to dedicated 40L+ portable refrigerators
−Heavier and bulkier than any dedicated portable fridge - storage and installation require planning
−Offers full value only when paired with EcoFlow ecosystem hardware - standalone functionality is limited
−Higher operational noise than dedicated compressor fridges when AC is active

Bottom line: The EcoFlow Wave 3 is an innovative and genuinely useful product for a specific, well-defined user - the off-grid van lifer building a complete EcoFlow-based power system. For anyone primarily seeking portable refrigeration alone, a dedicated compressor fridge offers more capacity, lower power draw, and better value.

The EF ECOFLOW WAVE 3 represents a philosophically different approach from every other unit in this guide. Rather than being a dedicated portable refrigerator, it is a portable air conditioning and heating system with an integrated food cooling compartment - designed as the thermal management centerpiece of a complete mobile living setup. ^[1] With 6100 BTU of cooling capacity, it can meaningfully reduce interior temperature in a converted van or small room while simultaneously maintaining a refrigeration zone for food and drinks. This dual functionality has genuine appeal for van lifers who would otherwise need to budget, space-plan, and power-manage two separate appliances. The EcoFlow app provides the most sophisticated ecosystem integration of any product in this guide, including solar production forecasting, battery state-of-charge monitoring, and scheduled cooling based on anticipated power availability - capabilities that transform it from a simple appliance into a system-aware component of a smart off-grid setup.

The Wave 3's significant limitation is its power consumption profile. While a dedicated fridge like the Dometic CFX3 35 draws just 28–38W at steady state, the Wave 3 consumes substantially more power when its AC functionality is active - making it incompatible with modest solar and battery setups. ^[4] You will need a large battery bank, at minimum EcoFlow's Delta Pro or equivalent capacity, to run it through a full night. At $700–$900, it is also the most expensive product in this guide. For users who are not already building around EcoFlow hardware, or for anyone whose primary need is food refrigeration rather than integrated climate control, a dedicated compressor fridge will be more practical and dramatically more power-efficient. ^[5] But for the committed van lifer constructing a complete solar-plus-battery mobile living system, the Wave 3 is an innovative and genuinely compelling cornerstone appliance.

Best Dual-Zone for Families & Extended Road Trips

Iceco VL45 ProD#

Best for: Families of three to five on multi-day road trips, couples who want dedicated simultaneous fridge and freezer compartments, and truck or SUV owners with ample, permanent cargo area

Strengths

+45L total capacity split between two independently controlled compartments - largest usable space in this guide
+Both zones reach -4°F (-20°C), providing complete flexibility to use either or both as a freezer
+USB charging port on exterior panel for convenient device charging without extra cables
+SECOP compressor ensures reliable, quiet, and efficient operation with proven long-term durability
+Integrated trolley wheels and grab handles make moving a fully-loaded unit genuinely manageable
+Three-stage battery protection with panel-adjustable cutoff voltage for overnight use

Limitations

−Large footprint requires careful measurement of cargo area before purchasing - will not fit all vehicles
−Fully loaded weight exceeds 55 lbs, making it the heaviest unit in this guide
−Bluetooth-only app connectivity - no WiFi remote access when away from the vehicle
−Zone divider occupies physical space, reducing effective capacity versus the stated 45L spec
−Lid opening direction is fixed on most retail variants - verify compatibility with your install location

Bottom line: At $280–$340, the Iceco VL45 ProD offers the best value per liter and best dual-zone flexibility in this entire guide. For any group that needs both cold food and frozen items on a road trip, it is the easiest recommendation we can make.

The Iceco VL45 ProD solves the single biggest practical limitation of most portable car refrigerators: the inability to simultaneously maintain true refrigerator temperatures in one section and true freezer temperatures in another. ^[3] At 45 liters total, it provides roughly 60% more interior space than the BougeRV CR Pro 30Q, divided between two independently adjustable compartments. Each zone can be set independently anywhere from -4°F to 50°F (-20°C to +10°C), meaning you can run one side as a refrigerator at 37°F while maintaining the other as a freezer at 5°F - the most practical configuration for a family road trip where cold beverages, dairy, and fresh produce share space with frozen meats and ice cream. The SECOP compressor manages both zones efficiently, and the three-stage battery protection ensures reliable overnight operation without risking vehicle battery damage. ^[2]

One practical advantage the Iceco VL45 ProD holds over every other unit in this guide is its integrated trolley wheel system. Moving a fully-loaded 45L fridge from a vehicle to a campsite or picnic area is genuinely physically demanding without wheels - a detail that larger-format fridge buyers frequently overlook until they experience it in the field. ^[8] The exterior USB charging port is a thoughtful addition for keeping phones and GPS units topped up without running cables to the vehicle's 12V socket. Where the VL45 ProD shows the constraints of its price point is in connectivity: like the BougeRV CR Pro 30Q, it offers Bluetooth-only app monitoring rather than the full WiFi remote access of the Dometic CFX3 35. For families prioritizing capacity, dual-zone flexibility, and practical portability over premium connectivity at $280–$340, this trade-off is straightforward to accept. ^[4]

Portable Car Refrigerator Buying Guide

Everything You Need to Know#

The 12 Key Criteria for Choosing the Right 12V Car Fridge#

Cooling Technology: Compressor units (like all five picks in this guide) are the only viable choice for reliable portable refrigeration. They reach precise, fixed target temperatures regardless of ambient heat. Thermoelectric (Peltier) coolers can only cool approximately 40°F below surrounding air - in a 95°F car, the best thermoelectric cooler reaches only ~55°F, which is not food safe.
Temperature Range and Freezing Capability: Look for a minimum rated temperature of at least 32°F (0°C) for food-safe refrigeration. If you need to freeze food, meat, or ice cream, choose a unit rated to -4°F (-20°C) or colder. The Dometic CFX3 35 leads the category at -7°F (-22°C).
Capacity Relative to Group Size and Trip Length: Budget 20–25L for solo travelers on short trips; 28–35L for couples on multi-day outings; 40L+ for families of three or more, or any trip longer than four days. Always measure your vehicle's cargo area before ordering a large-format unit.
Power Consumption and Duty Cycle: Quality compressor fridges draw 35–45W at steady state. Calculate daily energy use: at 50% duty cycle, a 40W fridge consumes roughly 480Wh per day. Pair that against your battery bank capacity to determine how many days of runtime you have without recharging.
Battery Protection Settings: Essential for overnight or parked use. Three-stage protection with adjustable cutoff voltages gives you the most control. Never run a fridge without battery protection enabled - a deeply discharged vehicle battery may not start your engine.
Dual-Zone vs. Single-Zone: Dual-zone units like the BougeRV CR Pro 30Q and Iceco VL45 ProD allow you to simultaneously run one compartment as a refrigerator and the other as a freezer. Single-zone units like the Dometic CFX3 35 maintain one consistent temperature throughout the entire interior.
Voltage Compatibility: All quality portable fridges support 12V/24V DC for vehicle use. Look for units that also include 110V/240V AC adapters for use at campsite hookups, home storage, or shore power connections on boats and RVs.
App and Smart Connectivity: Bluetooth is standard in mid-range units (30-foot range). WiFi connectivity, available on the Dometic CFX3 35, enables real-time monitoring and alerts when you're away from the vehicle - particularly useful for remote expedition use or when leaving food unattended.
Build Quality and IP Rating: An IP54 rating ensures protection from dust ingress and water splash from any direction. For off-road use, look for MIL-STD-810G vibration certification. Check that handles, hinges, and latches are metal, not plastic, on any unit intended for rough use.
Portability - Weight, Handles, and Vehicle Fit: A fully-loaded 45L fridge can exceed 60 lbs. Integrated handles, trolley wheels, and grab bars make a material difference in daily usability. Always verify the unit's external dimensions fit your specific vehicle's cargo space before purchase.
Noise Level During Operation: Quality compressor fridges operate at 40–50dB - roughly equivalent to a quiet library or soft background music. Budget units can reach 52–58dB, which is noticeable in a quiet cabin. Check hands-on reviews for real-world noise assessments rather than relying solely on manufacturer specifications.
Price and Warranty Length: Budget $100–$130 for entry-level compressor capability (Alpicool C20); $230–$340 for mid-range dual-zone units with freezing (BougeRV, Iceco); and $500–$900 for premium or specialized options (Dometic, EcoFlow). Look for at minimum a two-year compressor warranty - the compressor is the most expensive component to replace.

Editor’s Note

Pro Tip: Calculate Your Power Budget Before You Buy

Before purchasing a portable fridge, run this simple calculation: multiply the fridge's average watt draw by 24 hours to determine daily watt-hours needed. A 40W compressor fridge at 50% duty cycle uses approximately 480Wh per day. A standard 100Ah/12V vehicle battery stores roughly 1200Wh but should only be discharged to 50% (600Wh) to preserve battery health - giving you about 1.25 days of runtime. Add a single 100W solar panel and you produce 400–500Wh on a sunny day, bringing you close to break-even. Two 100W panels in good conditions will run most portable fridges indefinitely. For overnight van or truck camping, a dedicated 100–200Ah auxiliary battery is strongly recommended over relying on your starter battery.

Compressor vs. Thermoelectric vs. Absorption: Which Technology Is Right for You?#

The three main cooling technologies for portable refrigerators represent entirely different engineering approaches with correspondingly different real-world performance profiles. Compressor-based units - like every product in this guide - use a mechanical refrigeration cycle identical in principle to your home refrigerator: a motor-driven compressor circulates refrigerant through an evaporator coil, extracting heat from the interior and expelling it through a condenser. This allows them to reach precise target temperatures, including well below freezing, regardless of ambient conditions or how hot the surrounding air gets. They are the only technology suitable for reliable food-safe portable refrigeration. ^[5] Thermoelectric coolers - also called Peltier coolers - use solid-state semiconductor elements to create a heat differential when current passes through them. They have no moving parts, are completely silent, and are inexpensive to manufacture, but can only cool approximately 40°F below ambient temperature. In a 95°F car interior, the best thermoelectric cooler will reach approximately 55°F - well above the 40°F threshold for safe food storage, and completely inadequate for freezing. ^[3] Absorption coolers are found primarily in dedicated RV refrigerators and use an ammonia-water cycle driven by a heat source (propane flame or electric heating element) to achieve refrigeration. They are quiet, require no compressor, and can run on propane for extended off-grid use, but cool slowly, respond poorly to being off-level, and are significantly less efficient on 12V DC power than a modern compressor fridge. For portable car refrigeration in any context in 2026, compressor technology is the only category worth considering.

Editor’s Note

Do Not Confuse Thermoelectric Coolers with True Refrigerators

Many products marketed as '12V car coolers' or 'portable electric coolers' at prices under $80 are thermoelectric units - not compressor refrigerators. These devices cannot maintain food-safe temperatures (below 40°F) in warm weather, and their cooling performance degrades rapidly as ambient temperatures rise. If a product's specifications mention 'Peltier technology,' 'thermoelectric cooling,' or does not list a minimum temperature below 32°F, it is not a true refrigerator. All five products reviewed in this guide use genuine compressor-based refrigeration technology.

Key Takeaway

The Iceco VL45 ProD is the best dual-zone portable car refrigerator under $300 in 2026, offering 45 liters of independent two-compartment cooling - both zones capable of reaching -4°F (-20°C) - at a price of $280–$340.

Frequently Asked Questions About Portable Car Refrigerators#

Frequently Asked Questions

What's the best portable car refrigerator for a road trip in 2026?

For most road trips, the BougeRV CR Pro 30Q is the best choice - it offers dual-zone capability, genuine -4°F freezing, whisper-quiet operation under 45dB, and reliable battery protection at $230–$280. Families of four or more who need both refrigerator and freezer space simultaneously should step up to the Iceco VL45 ProD, which provides 45 liters of dual-zone capacity at $280–$340. For travelers on a strict budget making their first upgrade from a traditional passive cooler, the Alpicool C20 provides genuine compressor cooling at under $130.

What's the difference between a 12V compressor fridge and a thermoelectric cooler?

A 12V compressor fridge uses the same refrigeration cycle as your home refrigerator - a motor-driven compressor, refrigerant, and heat exchanger - to reach precise target temperatures including well below freezing, regardless of ambient air temperature. A thermoelectric (Peltier) cooler uses solid-state semiconductors that create a heat differential when current passes through them. Thermoelectric coolers have no moving parts and are silent, but can only cool approximately 40°F below ambient temperature. In a 95°F car interior, the best thermoelectric cooler reaches only ~55°F - far above the 40°F food safety threshold and completely unsuitable for reliable refrigeration in warm weather. For any serious portable refrigeration need, a compressor-based unit is the only appropriate choice.

Will a 12V car fridge drain my battery while parked overnight?

It depends on your battery's capacity and the fridge's battery protection settings. A typical compressor fridge operates at roughly 30–50% duty cycle once the contents are chilled, consuming approximately 300–500Wh over an eight-hour night. A standard group 27 deep-cycle battery holds roughly 1200Wh but should only be discharged to 50% (600Wh) to avoid damage - providing approximately one to two nights of runtime. Always activate the fridge's battery protection feature, which automatically cuts power at a safe voltage threshold. For regular overnight parked use, a dedicated auxiliary battery (100–200Ah) or a solar charging system is strongly recommended to avoid any risk of being unable to start your vehicle.

What size portable fridge do I need for a family of 4?

A family of four on a multi-day road trip typically needs 40–60 liters of total refrigeration capacity. The Iceco VL45 ProD at 45 liters dual-zone is our recommendation: it provides ample space for three to four days of family-sized food provisions with a dedicated freezer compartment for frozen items. For trips longer than four days, plan for a resupply stop at a grocery store rather than trying to carry a full week of food in a single unit. A useful packing benchmark: one liter of fridge capacity accommodates roughly one to two cans or the equivalent in fresh food. For a family of four over four days, plan for 45–60 liters minimum.

Can I run a 12V fridge off a solar panel and battery setup?

Yes - a 12V compressor fridge is one of the most compatible loads for a solar-plus-battery off-grid power system. A single 100W solar panel in good sun conditions produces 400–600Wh per day depending on location and season. A 35–45W compressor fridge at 50% duty cycle consumes roughly 420–540Wh per day - meaning one 100W panel can approach energy neutrality in a sunny climate, and two panels provide comfortable surplus for most locations. For the most reliable off-grid setup, pair your fridge with a 100Ah LiFePO4 (lithium iron phosphate) battery - its flat discharge curve and 80–90% usable depth of discharge make it far superior to lead-acid for this application. The EcoFlow Wave 3 integrates most deeply with EcoFlow's solar and battery hardware for a fully managed ecosystem approach.

What is the quietest portable car refrigerator available in 2026?

The BougeRV CR Pro 30Q is among the quietest available at under 45dB during normal operation - roughly equivalent to a quiet library or soft rustling leaves. The Dometic CFX3 35 is similarly quiet thanks to its variable-speed compressor, which reduces RPM once the target temperature is maintained, lowering both noise and power draw during stable operation. By contrast, the Alpicool C20 operates at approximately 52dB - equivalent to a normal conversation - which is noticeably louder in a quiet vehicle interior. As a practical guide: 40–45dB is whisper-quiet, 50–55dB is audible but non-intrusive, and anything above 58dB will likely be noticeable during overnight use in a tent or enclosed sleeping area.

What's the best dual-zone portable fridge under $300?

The Iceco VL45 ProD at $280–$340 is the clear answer for dual-zone performance near the $300 price point. It provides 45 liters of total capacity split between two independently controlled compartments, with both zones capable of reaching -4°F (-20°C). It also includes a USB charging port and integrated trolley wheels at no extra cost. The BougeRV CR Pro 30Q at $230–$280 is a lower-priced dual-zone alternative with a smaller 30-quart footprint. If maximum capacity is the priority and your cargo area can accommodate the VL45 ProD's dimensions, choose the Iceco. If space is at a premium or the price gap matters, choose the BougeRV.

How cold can a 12V compressor fridge get - can it actually freeze food?

Yes - the best 12V compressor fridges achieve genuine deep-freeze temperatures. The Dometic CFX3 35 reaches -7°F (-22°C), while the BougeRV CR Pro 30Q and Iceco VL45 ProD both achieve -4°F (-20°C) - all well below the 0°F (-18°C) standard for safe long-term food freezing defined by the USDA. The Alpicool C20 is the outlier: its rated minimum temperature is exactly 32°F (0°C), which means it refrigerates reliably but does not freeze. When evaluating any portable fridge, check the minimum temperature specification explicitly in the technical datasheet rather than in marketing copy. Units that reach -4°F or colder will freeze food; units rated above 32°F will not, regardless of how they are marketed.
