Included with the Powertube and an instruction manual contained. The external battery was fully charged at me. If this is not the case, you have to charge it first. This can be done via the USB port of a PC or a USB mains adapter. Unfortunately, such is not included. Normally you have a smartphone owners but at home, so that should pose no problem at such.
Compatible with mobile phones is the Powertube, smartphones, tablets, e-readers, PDAs, navigation devices, MP3 players, iPod, iPhone, iPad, Samsung, HTC and Nokia. An extensive adapter kit with 4 adapters is included with the package.
I especially like the built-in flashlight that lights up when you press the On button twice. A great and above all very useful extra. If you have the external battery case, one including a flashlight shall enter in future. I personally find very convenient.
After the battery is charged, you can take with them and wait for his use it anywhere. This would, however, come back soon, because who does not know this, you are traveling and the phone battery breaks down. For this one has now a power bank. This one connects simply via a charging cable to the phone and even the battery is charging.
Recharging works very well. The battery is charged without any problems and the LED display shows the battery level. The price is in comparison to other Power Tubes downright cheap, yet the device of McGrey served its purpose very well. The charging time is not much longer than when I boot my I Phone into an AC outlet. Therefore, I can find no great differences compared to other charging. The black design is simple but modern. The blue LED display shows the battery visually again a great kick. I admit the Powertube of McGrey therefore 5 stars and recommend it further without hesitation. The device is an absolute blast in the price-performance ratio.
