2 of 5 Battery works, indicator lights don’t June 7, 2021
Reviewer: Anonymous Person from WA, USA  
If you’re the type of person who would drive a new car with a busted gas gauge, this is the expensive battery for you. One iPhone 11 charge will take your battery from 4 full lights down to a single flashing light. But FEAR NOT, the battery will still charge your phone 5 more times while it’s “almost dead.”

Disappointing that this battery isn’t functioning correctly, more disappointing that their customer service hasn’t replied to my email. Have since heard other purchasers say they are having the same issues. Defeats the purpose of why I carry a battery this large, unless you’re able to nero into a hostel and take a full night to charge the unit, you’ll never know how much battery you actually have. Was hoping for more, May just as well switch back to the Anker as they’ve really reduced their weight on the current models and they’re proven reliable for 1/3 the price.

1 of 5 Unit does not function as intended May 22, 2021
Reviewer: Michael from California  
My unit does not provide the necessary power that is promised. After barely more than one iPhone 12 charge the battery fails. The indicator lights also do not seem to represent the amount of charge left. Extremely disappointed with my purchase. Would not recommend anyone to buy this product until nitecore improves its process or QC.

Reviewer: Jack Roth from Aiken, SC United States  
On my first charge the battery expanded and released the glue joints on the carbon fiber coverings. I took pictures and sent the Power Bank back, but have yet to hear anything from Nitecore.....

5 of 5 At first glance… May 10, 2021
Reviewer: Dadtke from Shakopee, MN United States  
I may update the review after field testing, but this power bank is exactly what I have been looking for. Compact and light considering the amount of mAh, it fits in really well with my solar charger needs. All the specs are just what I wanted and it shipped fast from Nitecore. Here’s to hoping it performs in the field 🍻.
