The 7800 mAh Power Bank RAVPower with iSmart is a recommendable product. The Power Bank was Frustfrei packed as indicated, with an approximately 65 cm long USB> Micro USB cable and a multilingual instruction manual, supplied. Size and design make a good impression. The Power Bank is well in the hand and looks sturdy (they did not drop). The 2.4 A charge current can be called truly 'Power' and I could my smartphone (ASUS Padfone S 2300 mAh) three times, with a power bank charge, within two hours, fully charge (smartphone battery at about 5 %). Mathematically, a rest of 1245 mAh in the Power Bank would even have been, but lt. Manual will recommend charging the Power Bank, if only one of the four LEDs lights up. To ensure longevity of the Power Bank battery, you should stick to it. This also means avoiding a passage charge (load Power Bank, while a device is connected). The ASUS Padfone Station (tablet with 4999 mAh) and could easily be fully charge and the Power Bank also ended here every time the charging process as soon as it was completed. Recharging the Power Bank took a 2 A charger (not supplied) as indicated only (!) Four hours to a USB output on your PC, it took almost twice as long, which is roughly also the charging time when a 1A charger uses. It is recommended that a charger with max. 2 A.
Conclusion: size, design, 2.4A charging current and the shutdown making the Power Bank a top product (!). We recommend. There is no more than a small bag or bags in which you can store or transport the power bank safe.
