This battery I bought because I (also Nitetec) have unfortunately misplaced the previous model - of course, it has resurfaced - therefore I have two ... This battery is manufactured with a wonderful valent metal housing and has two outputs, 1A and 2.1A. In addition, the battery is honest, it is not advertised unattainable mAh but with real, the also the battery performs after a few charge / discharge cycles - that I verbrät with a well-defined consumer of exactly 500mA measured. Well, that makes the battery but not so special to minimum not particularly good as other batteries. This battery has added value, namely a built-in flashlight and has already proved several times to be very practical. Great Thing! The display is also well thought out and shows fairly accurately how much capacity is left. Conclusion: An absolutely recommendable and honest product at a good price.
