Great performance and price
Im really impressed, especially at their price point. Love the micro USB charge port on the battery as I don’t have a Li-ion charger. These batteries push the output of my Klarus Mi7 Ti to the max which is great. I haven’t had them long enough to comment on how long they hold a charge or their resistance to developing memory, so I can only give 3 stars. But so far performance is great.

I like that you aren't limited to just a plug in wall charging unit and can also use a usb cord to charge this battery on the go , came with a full charge and was ready to use right out of the package ! on my list for buying again !!

So far, so good. So convenient.
So far, so good. Each cell charges up in about 2 hours from completely dead. Output in my Jetbeam SF-AA01 is great.

Buy It. if you have the right flashlight
Bought these for a coast HX5 flashlight. it can use AA or 14500 battery. This 14500 is so much brighter and having a micro usb port to charge it directly is awesome. Make sure your flashlight supports 14500 or you will fry it.

Klarus AA USB LiIon Battery
I happened by accident on these great AA USB batteries. Am used to using the Smartoools AA/AAA USB batteries but this is a LiIon rechargeable battery. Friends & colleagues borrow my charger, came to the conclusion that I required a battery with a built-in USB port. And here it is. I gave it approximately 3H to charge and used them right away (ordered 8, comes 2pr/box). These nifty batteries handles all of your LiIon power requirements and more. Like the Smartoools A/AAA batteries, they are well constructed. Am looking forward to ordering more of these batteries. If you happen to have a PowerFly solar hydration backpack(Amazon), you can also charge these batteries from there as well. They also charge using a Goal Zero, Wagan, Yundu YD-T015 solar panel systems. RECOMMEND: Buy a few (I did).
