Even after prolonged use still full power available (for version experiences 13,000 mAh)

An external battery is a portable device that can send its power to other equipment. Better known are those devices under names such as Power Bank battery or power pack. There is little battery packs that are handy, light and their performance (2200-3600 mAh) is sufficient for max. A full charge of a smartphone. The RavPower battery bank, which is offered here with 13,000 mAH, one of the most powerful devices. Because this battery can store much energy, it is a bit larger and heavier than the smaller brethren. A smartphone can be times completely recharge with the power of 13,000 mAh about 6. After all, an iPad or similar tablet become scarce once charged. When a battery pack is exhausted, it is recharged at the mains again. This circuit works according to the manufacturer about 500 times.

Mir the battery in a neat package was delivered. Thus, the battery is absolutely as a gift, because who has presented something in an ugly packaging? The scope of delivery exceeds what I expected: The Power Bank, a USB charger, various adapters (eg for Apple iPad, older mobile phones, etc.), a transport bag and instructions. It has nothing unpleasant smell when unpacking.

The RavPower battery looks very classy. It is high-quality. Sharp edges or other claims do not exist.

On the device itself, there are two USB outputs. This means that two devices can be charged simultaneously. Which output is used for which device, does not matter. The RavPower Battery Bank recognizes this and automatically adjusts itself to the device to be charged. A charging process takes a not inconsiderable longer than directly to the mains.

At this point I want to mention how versatile these battery packs times. Thus, not only smartphones or tablet can namely be charged. This battery is ideal for all sorts of small appliances. I use this battery for my Bluetooth headset, my old MP3 player and even a USB Christmas Lights, which just hangs in the guest bathroom near the window where no power outlet is available. Not only that: The battery can be the runtime of a little Bluetooth speaker extend for hours. Even during operation. Ideal if you are traveling.

How much battery capacity is still on the Power Bank, one always recognizes the blue LED lights. They signal clearly how full the battery is still.

The further features of the external battery via a torch light. I've seen in various models and still think, that this is indeed meant nice, but in fact is hardly useful. It turns out one or even when the power switch is pressed twice in quick succession.

I use this power bank now a bit longer. There are no complaints! Still true performance. So Deterioration of the battery I can not even notice.

Conclusion: This battery is powerful. He looks good, is suitable for current smartphones and older small appliances. Thus one has the road always a strong Power Bank for emergencies. I hope my post was helpful. From me there is a full purchase recommendation.
