UGREEN Nexode 20000mAh 145W Built-in USB-C Power Bank

Why it's worth it

This 20,000mAh bank pushes up to 100 watts from one USB-C port, which is real laptop charging rather than a slow trickle. Use two ports and you get 100W plus 45W at once, so a laptop and a tablet can both come back from empty.

This is the one that makes an outlet optional. A hundred watts from a single port covers a MacBook Pro, and the 20,000mAh capacity means a full laptop refill with room left for a phone. If you work from trains, airport gates and conference floors, that's the difference between rationing your screen brightness and just working.

The dual-USB-C setup is smarter than it first looks. There's a built-in USB-C cable plus a separate 45W USB-C port, so two laptops can charge from one brick without you carrying a second cord. It also speaks PD, PPS, SCP and UFCS, which in plain terms means iPhones, Samsung, Xiaomi and Huawei phones all get their proper fast-charge speeds instead of a generic slow one.

What we like

• +This is the one that makes an outlet optional
• +The dual-USB-C setup is smarter than it first looks
• +PCMag notes that the onboard display shows real-time output, and on a bank this powerful that's more than a gimmick
• +At 20,000mAh it also stays within the capacity airlines generally allow in a carry-on, which is why this size is the sweet spot…

What to know

• –It weighs about a pound, and owners bring that up constantly
• –Check what your laptop demands before you buy
