I love the battery...looks durable and tough. Thanks Nitecore.
Great Battery... Small size with lota of power in it...will get more of nitecore products!
Another option of swapping over fully charged battery even thought there is a convenience of built in USB charger.
The item was fantastic and I love it, it perfectly work to its best and functionality.
Thanks you NITECORE
