Practical voltage reserve

I tested the battery with my smartphone and my tablet, both of which are rapidly charged so again. Of course not full but plus approximately 45% (tablet) or 70% (Smartphone) creates the battery. Two drawbacks are noticed: while charging the battery itself this is quite warm, and charge the battery itself takes a long time (much longer than the loading of smartphones or tablets later), about 4 hours. As an advantage, I feel the display of charging or discharging through the LEDs. So is immediately apparent when the battery is ready for use or can be o.ä.abgedockt from Smartphone / needs to be recharged itself.

Has proven to be the battery, I had actually purchased only as a joke, the move as an emergency reserve in the car or in your pocket. Or even on the couch or in bed when the nearest outlet is inconveniently located, and one with no cross-tensioned through the space charge lead his smartphone (or similar) would keep them alive while you use it. Of course, this only works if you remember, the battery also recharge again.

Small note yet: the supplied cable is quite short (15cm), which can be advantage or disadvantage depending on the application, you want to battery and device somewhat distant from each holding (eg battery in your pocket and Smartphone in hand), must you look at a longer second cable get. With the trend towards unified micro-USB charging plug but each a suitable cable has probably now been lying around at home.

Conclusion: For people who want smartphone or tablet junkies who go can not estimate their energy needs, or on a sofa and coffee comfortable daddeln / surf, this battery is an acquisition, over which one can think. Not essential, but nice to have ;-)
