5 of 5 Great High Output 21700 Battery September 18, 2023
Reviewer: Steve Klein from Somers Point, NJ United States  
This is a great 21700 battery with a whopping USB-C 5V-2A output. A 5000mAh battery with an 18-Watt Hour capacity. (Input-USB-C 5V-2.5A) Definitely charge it by itself, with a 2.5V to 3.0V wall charger. The Nitecore Quick Charge 3.0 USB Adapter or the Nitecore UA42Q USB charger will work fine. Then I finish it off with my Nitecore USM4 charger, to see all the stats inside the battery. It does not charge quickly because of its 18-Watt hour capacity. Put an inline Volt, Amp Hour & Watt reader device on it, because when the charged light comes on it's only 75% to 100% charged, as most C-Port charging batteries, flashlights and other devices are. That charged light, or 4th light coming on, means it's between 75% to 100% charged. You can use it as a power pack or it works in most hi-drain 21700 flashlights. (my Nitecore MH25S & MH12SE, in particular) I'm glad I got one and I'm getting more for my family to charge their laptops and iPhones, in a "no electricity situation".

5 of 5 Easy choice August 24, 2023
Reviewer: R Roberts from Tampa, FL United States  
I use mine for ultralite hiking. Added a drop of silicon (from a housing sealent tube) on each end. This new battery is legit and though the lightest, it's got tiny heft. Matched advertised weight and capability.
-Site simple and smooth. Products are quality. Shipping is timely. Can't beat it.
