Nitecore NB20000 Gen 3 (20,000mAh/Carbon Fiber/IPX5 Ultralight Power Bank) Review
The Nitecore NB20000 Gen 3 is a 20,000mAh, 72Wh power bank rated IPX5 water-resistant, with dual USB-C ports supporting up to 22.5W each and USB-C pass-through charging.
This is the pick if you want a lot of capacity in a bank that can handle a splash. It's above the 100Wh airline threshold at 72Wh, so it's fine to carry but worth knowing before you pack it.
Ports and Charging
Two USB-C ports (both input/output capable) deliver up to 22.5W each, with an included USB-C to USB-A adapter for older accessories, and pass-through charging support.
Durability
IPX5 water-resistance and a 291g weight make this a reasonable choice for outdoor or worksite use where a drop of rain shouldn't be a problem.
