Comprehensive, powerful and well built. This is an excellent extra battery that keeps its promises. Tested on different devices recharge it without flinching in time entirely correct. The design is really nice, it is not so heavy or cumbersome for such a capability. A suitable price, it's all good. Totally satisfying! Definitely recommended.
