I have received the RAVPower 13000mAh with flash light and 2 A adapter in black for free as part of product testing. Included in the package were: 1 Power Bank in black 16000 Ah 1 charging cable, USB cable to microUSB long, 60 cm 1 charging cable, USB cable to microUSB short, 20 cm 1 2A Adapter 1 bag 1 Operating Instructions Technical Specifications: Capacity: 16000mAh Input: DC 5V / 1.5A (standard microUSB port) Output: DC 5V / 4.5A (2.1A + 2.4 A) Compatible power bank mi tiPad Air 2, iPad 3 Mini, iPhone 6 6 +, iPod and smartphones like Samsung / HTC / LG / Motorola / Blackberry / Nokia / Sony etc. Caution: The charging cable or adapter for Apple devices is not going to charge it with your original charger cable. The dimensions of the Power Bank are 12.7 x 8.1 x 2.2 cm. The weight is 281 grams. On the narrow side down, in the terminals, there is a built-in flashlight, and the two connectors (1 small and 2 large USB connector) for charging. The switch for the flashlight is the power switch on the front of the Power Bank. The flashlight is turned on by pressing the power button, press it again to turn off also 2 x. The Power Bank is used to charge the device can on the road, where there is no other way to charge is. For example, if you are traveling by bike and the machine is empty. Even in the dark flashlight is a little helper. The color of the Power Bank is black and therefore unisex. The product itself is very stable and easy to handle despite its size and weight. The application is quite simple. First you have to charge the Power Bank itself. This is done by plugging the small USB plug into the Power Bank and the big USB plug into the charging adapter for the power outlet. I have taken my charging adapter from your smartphone. The charging time is several hours. If you charge the Power Bank, lights on the front of the blue LEDs. When fully charged, these LEDs light up in all 4 fields and thus you know when the power bank is fully charged. Each field is 25%. The manual I did not need, because even I as a woman with a little knowledge of technology, the operation had detected immediately. To charge the other device simply turns around the plug. The small USB plug comes in the mobile phone and the large connector into the Power Bank. How long does the Power Bank I can not say yet. I have once fully charged and used several times to recharge in between times, until I could to the wall socket. After several uses, the Power Bank is still not empty. I think it is very good value for money. I highly recommend this PowerBank very happy to help. I like to give full credit for a device which 2 devices simultaneously charges quickly.
