Want to take great Kauftip for all the "Power"

A Power Bank, what a brilliant invention!
With this "battery" has reserve for smartphones, Ipad or other devices with a matching USB port.
After I ordered from Amazon, the delivery was carried out on the second day, finally a fast shipment of Amazon after the last time the packages had a term of less than one week, but only in passing.
After unpacking, I had a reasonable Plastic Packaging in hand. Looks quality and not cheap. Even if a package is not the most important, the first impression is important.
What then directly struck me yet? The Weight. The Power Bank was quite difficult. Is it good? Yes, because how do because the "Power" come when no reasonable cells in the battery are. The V7 Power Bank 6600 mAh has a weight of 175 grams, which is a reasonable value iff one other compares, however.
You can compare it very well, by "power batteries" in the size AA and a thickness of 3000 mAh, which then cost 2.90 in 4-pack, sometimes taking in hand. The fact weigh nothing! How should come because the power-force, if no cells are in the battery? Exactly that cost little and are worthless.

Back to the topic V7 Power Bank 6600 mAh. What does this power bank? It costs 21.99 euros at Amazon in the store of Amabay. It offers there still an alternative variant with 4400 mAh of these will cost 19,88 Euro.
My tip is here but clearly the larger variant, because for just over 2 euros you also get 1/3 more battery power, and what would have underscore at the end, and what pays.

After the most important thing, the Power Bank and a charging cable before is. First, the Bank has fully loaded, the factory setting was at 50%, that is already partially charged and ready for rapid deployment. The current state when charging is indicated by a number of LEDs, the more the 4 permanently lit, the better.
This complete charging process lasted about 3 hours, then the bank was charged full. As a first test I've loaded my iPad mini, which was the storage side dropped to below 20%. The complete charging process took about 1 hour.
Is very nice, in the Power Bank a white LED as a flashlight is integrated centrally, you can turn a small switch on the Seiter. Highly do good if you are traveling at night. In the dark time of year can be worth a small flashlight gold! The small LED has a good light output, enough for small works from completely or lit a path / road until about 8 feet out.

What is the use of a power bank?
Basically, this is known to everyone, at least those who buy such.
I also have a variety of applications because I travel a lot and am always rely on "Battery Power". I show current uses of a photo shoot, which I have done in a wooded area. Such appointments can take hours, or even take a whole day, depending on the event.
As one is grateful when the spare battery is a power bank is then like gold, because without energy is not possible! You get plenty of power, for very little money, it should be worth a but, right?
