The battery is delivered in a pretty simple package that can be opened to have to use slightly and particularly without any tools. I think that's always important. Charging the battery is now not incredibly fast from equip, but lasted a few hours, this is but of course not the product itself, but the fact that until now simply no battery technology exists on the market that could something, so it is no point deduction from my side. But of course it also takes time because as the battery has a large capacity. I already have a battery also of RAVPower with 13000mAh and already holds a long time, as this but again 3000mAh MORE has, he thinks, of course, much longer. I think with a conventional smartphone would definitely survive a one-week camping trip in the wilderness and then of course, the built-in flashlight to be practical. Personally I have until now not been used, but it may I think be already practically. As the only flashlight you is obviously not recommended, if only because of the square form factor of the battery, but there would also, I believe no one on the idea they come to use so. Even a bag is included, as I would, however, wish that they would forward them better able to close in little longer, but it definitely served its purpose. The connected devices are loaded very quickly. I have for example the large iPad power adapter for my iPhone and this invites the iPhone almost twice as fast as the standard power supply. At this speed, the battery can certainly compete. Overall, it's just a solid product, which you can recommend, especially for the price of 35th
