5 of 5 Surprisingly light and surprisingly long lasting. October 29, 2022
Reviewer: Michael Bowles from Tacoma , WA United States  
Works better than I could have hoped and was more than I could ever need for my recent hiking trips. I have no doubt this will be the perfect solution for my PCT hike next year.

5 of 5 best power bank yet October 2, 2022
Reviewer: Mark from crosby, TX United States  
I've tried a few powebanks before and this one is the best yet. I'm now able to comfortably charge my Samsung Fold to a full charge in about an hour multiple times on multi-day camping trips. Highly recommend

4 of 5 NB20000 Preliminary Review September 25, 2022
Reviewer: Thavery Tan from California Garden Grove , CA United States  
If you do a new and improved nb20000 like the nb10000, can you make all the markings “in” and “out” lettering in contrasting color, maybe in neon white or neon yellow so that it’s easier to see without my having to use a flashlight to see the wording. Absolutely great product support, with questions immediately answered. Also, can I get a free swap if a new nb20000 does come out?

5 of 5 Plenty of Power and Versatility September 6, 2022
Reviewer: Terry MunsTeon from Woodinville, WA United States  
Picked up the Nitecore NB20000 as an upgrade for my wife's backpacking trip on the West Coast Trail in BC. We normally use a 10000 mAh bank by another vendor for three- and four-day outings, which did fine. The NB20000 is for longer duration trips. During a multiday test outing in the damp Pacific Northwest we recharged two iPhones, a Garmin inReach, a headlamp and a couple of Garmin watches with the recharge capacity dropping to 75%. We appreciate the multiple ports and ease of use. Looking forward to more trips with confidence.
