UOG TOP PICK: Fast, light and easy to monitor, the Nitecore Carbo 20 gives backpackers serious 20,000mAh power with a clear battery display, 65W charging and trail-ready waterproof protection.
Nitecore says:
The NITECORE CARBO 20 Professional Outdoor Fast-Charge Power Bank features a 20,000mAh high capacity, 65W high-power two-way fast charging, IPX8 waterproofing, and a smart display screen. Equipped with a carbon fiber shell body, magnesium alloy heat sinks and high energy density cells, it delivers reliable power for outdoor sports and field work.
Our Verdict
The Carbo 20’s standout feature for me is the numbered battery display, which gives a much clearer idea of remaining power than the standard 4-blue-light display. At 320g, it is light for a 20,000mAh power bank, while the dual USB-C ports, 65W input and output, IPX8 rating, and carbon fibre shell make it feel well-suited to life on trail. The lack of USB-A is worth noting if you still use older cables, as I do for my watch.
