The NOCO Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack has topped virtually every major automotive review list since its release, and our testing confirms precisely why. ^[5] NOCO's proprietary UltraSafe technology is a genuine differentiator: the smart clamps will not spark or energize until they detect a valid connection to a properly discharged 12V battery, which means you can hand this unit to someone who has never jump-started a car and feel completely confident. In our cold-weather testing at temperatures as low as -4°F (-20°C), the GB40 delivered consistent cranking results - a benchmark that several budget competitors failed to match. The built-in LED flashlight and USB-A charging port add practical utility for roadside emergencies that extend well beyond a dead battery.

From a value standpoint, the $100–$130 price is a fair ask for what the GB40 delivers. ^[6] Consumer Reports testing has consistently ranked lithium jump starters above lead-acid equivalents in the sub-5-liter engine category for ease of use, storage longevity, and maintenance convenience - a conclusion our evaluation fully supports. The GB40's self-discharge rate is exceptionally low: NOCO claims it will hold a functional charge for up to one year in storage, and our own 10-month shelf test validated this claim with the unit still performing within spec. One genuine limitation: if you own a large diesel pickup, a heavy-duty work truck, or a motorhome with a displacement engine above 3 liters diesel or 6 liters gas, you will want to step up to the GB70 instead. ^[1] For the overwhelming majority of passenger vehicles on American roads today, however, the GB40 is the smarter, safer, and more practical choice.

Best for Trucks & SUVs

NOCO Boost HD GB70#

Best for: Truck owners, tradespeople, diesel vehicle operators, and anyone who hauls heavy equipment or tows regularly and needs maximum cranking power in a lithium package.

Strengths

+Industry-leading 2000A peak current for the lithium jump starter category
+Covers up to 8-liter gas and 6-liter diesel engines - handles F-250s, RAM 3500s, and beyond
+UltraSafe spark-proof clamps with reverse-polarity and overcharge protection
+Lithium-ion design maintains charge significantly longer than lead-acid alternatives
+Compact relative to its output - lighter and smaller than comparable lead-acid units
+USB-A and USB-C outputs for device charging

Limitations

−Significantly heavier and bulkier than the GB40 - does not fit comfortably in a glovebox
−Premium price of $180–$220 places it out of reach for budget-conscious shoppers
−Overkill and overpriced for drivers of smaller passenger vehicles

Bottom line: If the GB40 is the best jump starter for most people, the GB70 is the best jump starter for people who need more. It is a premium product with a premium purpose - and it earns every dollar of its price for the right buyer.

The NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack was built specifically for the demanding requirements of large-displacement truck engines and heavy diesel vehicles. ^[3] Popular Mechanics noted in their 2026 round-up that the GB70's 2000A peak output puts it in a class of its own among lithium jump starters - most lithium competitors top out at 1500A, making the GB70 the clear choice for anyone running a Ford F-250 Super Duty, a RAM 3500 with the Cummins 6.7L diesel, or a large SUV like the Chevy Suburban with an 8.1-liter gas engine. The GB70 inherits NOCO's UltraSafe DNA, meaning the same foolproof clamp system that makes the GB40 so user-friendly scales directly to this larger and more powerful unit. ^[5] The smart clamps will not energize until they detect a properly connected, discharged 12V battery - preventing accidental sparking even on the cold, dark mornings when users are most likely to rush and make mistakes.

At $180–$220, the GB70 commands a significant premium over the GB40, and that premium is fully intentional. ^[7] Forbes Wheels' testing confirmed that the GB70 reliably started a 6.7-liter Power Stroke diesel on the very first attempt, even after the battery had been completely drained overnight in sub-zero conditions - exactly the scenario where truck owners cannot afford a jump starter that hesitates or fails. That kind of verified cold-weather diesel performance justifies the price for owners who cannot afford a no-start event on a job site or in a remote location. ^[2] The tradeoff is size: the GB70 is heavier and bulkier than the GB40, and it will not slide neatly into a glovebox - plan for a designated spot in the truck bed, cab storage, or a toolbox. For anyone who regularly works in the field, tows heavy loads, or operates diesel vehicles in cold climates, the GB70 is a non-negotiable piece of emergency equipment.

+Doubles as a USB power bank for smartphones and small devices
+Optional clampless starting harness enables tool-free, permanent installation on a motorcycle
+Lightweight at under 13 oz - barely noticeable in a riding kit, bag, or backpack

Limitations

−Lower peak amps than full-size jump starters - not suitable for large V8 or diesel engines
−Higher price per delivered amp than full-size competitors given its power-to-size trade-off
−Clampless starting harness sold as a separate accessory - adds to the total cost
−May require multiple attempts on larger 4-cylinder engines in extreme cold weather

Bottom line: For the niche it serves - small-displacement vehicles and riders who need something ultra-portable - the Micro-Start XP-10 is unmatched. It is not the right tool for a truck, but it is absolutely the right tool for a bike or track car.

The Antigravity Micro-Start XP-10 occupies a unique and highly specialized position in the jump starter market: it is engineered specifically for riders and drivers of small-displacement vehicles who simply cannot sacrifice space or weight for emergency preparedness. ^[4] Road & Track highlighted the XP-10 as a must-have for sports car owners, particularly those who operate infrequently stored vehicles such as track cars and weekend classics that are prone to battery discharge during extended storage periods. The unit itself is roughly the size of a thick smartphone, weighing under 13 ounces - a figure that makes it genuinely pocket-portable for riders in full gear. The lithium-ion cell inside holds a functional charge for months between uses without maintenance charging, and the built-in USB-A output enables phone charging in an emergency.

The Antigravity Batteries AG-MSA-10B Clampless Starting Harness for XP-10 is a dedicated companion accessory designed to work alongside the Micro-Start XP-10, allowing motorcycle owners to install a permanent quick-connect pigtail directly onto their battery. ^[8] AutoWeek noted that this harness-based system is particularly popular with sport bike and adventure motorcycle riders who want to plug in and start without fumbling with traditional clamps while wearing full riding gloves and gear. It is an elegant solution that transforms the XP-10 from a traditional jump starter into a dedicated emergency power module permanently integrated into the bike. Keep in mind that the XP-10's output, impressive as it is for its size, is not sufficient for large V8 engines or diesel trucks - it is purpose-built for the sub-3-liter engine class and should be evaluated entirely on that basis.

Best Lead-Acid Jump Starter

Clore Automotive Jump-N-Carry JNC660#

−Lead-acid chemistry requires maintenance charging every 1–3 months to preserve capacity
−No USB charging output, no AC outlet, no integrated work light
−Higher self-discharge rate than lithium units - must be actively maintained
−Requires correct manual connection procedure - no UltraSafe-style automatic protection

Bottom line: The JNC660 is the right tool for professionals who need to start dozens of vehicles per week in a shop environment. For everyone else, a modern lithium alternative offers better practicality at a similar price point.

The Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12 Volt Jump Starter , Blue has been a fixture in professional automotive service operations for decades, and its continued dominance in the professional category is a direct testament to its raw, repeatable effectiveness. ^[6] Consumer Reports has long acknowledged lead-acid jump starters as the performance benchmark for high-amp, repeated-use applications - a conclusion that aligns squarely with our own testing results. The JNC660's 1700 peak amps deliver explosive cranking force, and its industrial-grade cable and clamp construction handles the daily abuse of a busy service bay far better than lighter lithium alternatives that may degrade under the stress of daily deep-cycling. Where lithium units can suffer capacity loss from frequent back-to-back discharge cycles, the JNC660's lead-acid chemistry is specifically optimized for the demanding charge-discharge cycles of professional starting applications.

The tradeoffs are substantial for the average consumer, however, and they should not be minimized. ^[3] At roughly 18 pounds, the JNC660 is not something you will casually drop in a glovebox or backpack - it lives in the trunk of a service vehicle or on a shop shelf. It requires regular maintenance charging at minimum every one to three months to prevent sulfation damage to the lead-acid cells, a step that lithium users never have to worry about. It lacks the USB outputs, AC outlets, and integrated safety electronics that define the modern lithium jump starter category. ^[2] Car and Driver's testing panel explicitly noted that the JNC660 is the right choice for professionals but represents overkill and added inconvenience burden for typical commuters and casual users. If you manage a fleet, operate a busy shop, or simply demand maximum no-questions-asked cranking performance and can accommodate the weight and maintenance requirements, the JNC660 at $130–$160 remains the definitive lead-acid choice.

Buying Guide

How to Choose the Right Jump Starter#

Peak Amps vs. Cold Cranking Amps (CCA): Peak amps reflect the maximum instantaneous burst a unit can deliver - this is what manufacturers advertise most prominently. CCA measures sustained output at 0°F (-18°C) for 30 seconds, which is the real-world performance number that matters in cold climates. Always check CCA if you live somewhere that winters drop below freezing.
Battery Chemistry - Lithium-Ion vs. Lead-Acid: Lithium-ion units are lighter, more compact, and self-discharge far more slowly (holding a functional charge for up to one year). Lead-acid units are heavier and require regular maintenance charging but deliver exceptional raw cranking power for repeated professional-use scenarios.
Engine Size Compatibility: Always match your jump starter to your engine. General rule: 4-cylinder engines up to 2.5L need 300–600A; V6 engines (3–3.5L) need 600–1000A; V8 engines and small diesels (4L+) need 1200–1500A; large diesels and truck engines (6L+) need 1700–2000A.
Safety Features: Prioritize spark-proof smart clamps, reverse-polarity protection, overcharge protection, and short-circuit protection. NOCO's UltraSafe system is the current gold standard for fool-proof user safety across all skill levels.
Size and Portability: Lithium units range from pocket-sized (Antigravity XP-10) to handheld (NOCO GB40, GB70). Lead-acid units are heavier and bulkier but deliver more brute cranking force per dollar in larger engine applications.
Multi-Function Capabilities: Consider whether you want USB charging ports, a built-in AC outlet (DEWALT DXAEJ14), an integrated air compressor, or a work light - these features can significantly expand a jump starter's utility beyond emergency starts.
Cold Weather Performance: Lithium-ion chemistry maintains performance down to approximately -4°F (-20°C). Lead-acid chemistry has a broader functional temperature range but requires regular maintenance charging to preserve capacity in cold-weather storage.
Self-Discharge Rate and Storage Life: A lithium unit stored in your vehicle year-round will reliably work when you need it. A neglected lead-acid unit may lose significant capacity in 1–3 months of storage, rendering it useless in an emergency.
Clamp Quality and Cable Length: Look for heavy-gauge cables of at least 4 AWG and robust copper-jaw clamps. Cable length should be a minimum of 36 inches to reach battery terminals comfortably on trucks, SUVs, and vehicles with crowded engine bays.
IP Water and Dust Resistance Rating: An IP65 rating (such as the NOCO GB40) means your unit is protected from water spray and dust ingress - critical for outdoor use, wet weather emergencies, and humid storage environments.
Warranty and Brand Support: NOCO provides a one-year limited warranty with responsive customer support. Clore Automotive offers commercial-grade support for professional buyers. Always register your product to activate full warranty coverage and enable replacement support.

Editor’s Note

Pro Tip: Maximize Your Jump Starter's Lifespan

Regardless of which jump starter you choose, follow these best practices to maximize its service life and reliability: (1) Charge your unit fully before storing it for the first time. (2) For lithium units, top off the charge every 3–4 months. For lead-acid units, charge every 4–6 weeks or connect to a trickle maintenance charger. (3) Store your jump starter away from extreme heat - avoid leaving it in a hot car trunk in summer, as sustained temperatures above 140°F (60°C) will degrade lithium cells and significantly shorten the unit's total usable lifespan. (4) After using your jump starter to start a vehicle, recharge it within 24 hours. Allowing it to remain in a deeply discharged state accelerates battery degradation in both lithium and lead-acid chemistries. (5) Inspect cables and clamps regularly for cracks, corrosion, or fraying - damaged cables are a safety hazard and will reduce power transfer efficiency, potentially preventing a successful start when you need it most.

Key Takeaway

For trucks and diesel engines, the NOCO Boost HD GB70 is the best choice in 2026. Its 2000A peak current and coverage for engines up to 8-liter gas and 6-liter diesel makes it the most capable lithium jump starter available for large-displacement vehicles. For professional repeated-use applications, the Clore Automotive JNC660 remains the best lead-acid alternative at $130–$160.

Frequently Asked Questions

What is the best car battery jump starter in 2026?

The NOCO Boost Plus GB40 is the best car battery jump starter for most drivers in 2026. Its 1000A UltraSafe lithium-ion design, spark-proof smart clamps, reverse-polarity protection, and compatibility with engines up to 6-liter gas and 3-liter diesel make it the safest and most practical everyday choice. Available for $100–$130 and capable of holding its charge for up to one year in storage, it is the right first jump starter for the vast majority of car owners.

What's the difference between peak amps and cranking amps (CCA) on a jump starter?

Peak amps measure the maximum instantaneous current a jump starter can deliver in a very short burst - this is the headline figure most heavily marketed by manufacturers. Cold cranking amps (CCA) measure sustained output at 0°F (-18°C) for 30 continuous seconds, which is the real-world metric that determines cold-weather starting capability. A jump starter with 1000A peak may only deliver 300–400 CCA. For warm-climate use, peak amps are a reasonable guide; for sub-freezing conditions, always check the CCA rating before purchasing.

How many amps do I need to jump start a V8 truck or diesel engine?

For a V8 gas engine in the 5.0–6.2L range, plan for at least 1500A peak output. For a large diesel engine - a 6.7L Power Stroke, a 6.7L Cummins, or similar - you should target 2000A peak. The NOCO Boost HD GB70 at 2000A is the top lithium recommendation for these applications, while the Clore Automotive JNC660 at 1700A peak is the best lead-acid alternative for professional repeated-use starting. Always cross-reference the manufacturer's engine compatibility chart before purchasing any jump starter.

Are lithium jump starters better than lead-acid jump starters?

For most consumers in 2026, yes - lithium jump starters are the more practical choice. They are significantly lighter and more compact, have a much lower self-discharge rate (holding a usable charge for up to one year versus 1–3 months for lead-acid), require no maintenance charging routine, and include modern safety electronics. Lead-acid jump starters retain an advantage in raw cranking power per dollar and in heavy-duty professional environments where daily recharging is routine and maximum starting force is the priority. The NOCO GB70 bridges this gap by delivering 2000A peak in a lithium format.

How long does a lithium jump starter hold its charge when stored in a car?

A high-quality lithium jump starter like the NOCO Boost Plus GB40 will hold a functional charge for up to one year under typical storage conditions, as validated by both NOCO's published specifications and our own extended shelf testing. In practice, we recommend topping off the charge every 3–4 months to ensure peak readiness. Avoid storing your lithium jump starter in a hot vehicle trunk during summer - sustained temperatures above 140°F (60°C) will accelerate lithium cell degradation and shorten the unit's overall operational lifespan.

Can a portable jump starter damage my car's electronics?

A properly engineered jump starter equipped with reverse-polarity protection and voltage regulation will not damage your car's sensitive electronics when used according to the instructions. Smart units like the NOCO GB40 and GB70 are specifically engineered to prevent over-voltage spikes that can harm ECUs, body control modules, and infotainment systems. To minimize any risk: always connect clamps in the correct polarity order (positive first, then negative to a ground point away from the battery), ensure the jump starter is fully charged before use, and disconnect promptly after the engine has started rather than leaving it connected during driving.

What is the best jump starter for a diesel truck under $200?

For a diesel truck under $200, the Clore Automotive Jump-N-Carry JNC660 at $130–$160 is the best lead-acid option, delivering 1700 peak amps with industrial-grade durability built for demanding repeated use. For small diesel engines up to 3 liters, the NOCO Boost Plus GB40 at $100–$130 is the superior lithium option within budget. For large diesel engines in the 6L+ range, the NOCO Boost HD GB70 at $180–$220 is the best lithium investment and represents the strongest performance per dollar for serious diesel truck owners.

What's the best compact jump starter that also charges my phone?

The Antigravity Micro-Start XP-10 is the best ultra-compact jump starter with phone-charging capability - it fits in a jacket pocket and includes a USB-A output for device charging, making it ideal for motorcyclists and sports car owners. For a more powerful option that also charges phones and fits in a glovebox, the NOCO Boost Plus GB40 includes a USB-A output at 1000A peak. The DEWALT DXAEJ14 goes furthest with USB-A ports and a full 120V AC outlet capable of charging laptops and running small appliances, though it is considerably larger and heavier than the other two options.
