On the device there are two USB ports, both of which can also be used at the same time to recharge. Once a device is connected to be charged, the Power Bank automatically start the charging process. So it does not need a power switch. A small button is located on the side, however, is twice quickly pressed to activate the flashlight on or off again. If the button is pressed only briefly, to show up to three blue LED lights, the remaining battery capacity of the Power Bank.
The Power Bank is high-quality. Unfortunately it is quite difficult for the performance. Since there is now a bit lighter models. Really great is the box in which the Power Bank is delivered. She is very strong, looks elegant and is thus suitable fine, as a gift. Who has been like something in a miserable packaging.
A USB charging cable is included. This device can be connected to the Power Bank to charge, or the Power Bank itself is so loaded on a mains plug to the mains. A power cord is not one as in most power banks, even here in the delivery. Just use the USB plug of your cell phones.
The empty Power Bank takes about one night to become again fully charged.
Although the Power Bank is now already longer in use, is no degradation in performance determine. If there soon change something, I will report.
I still wonder why there is an integrated flashlight light with so many power benches. I can understand it still in the very small models, but not in this monster. I mean, who uses a relatively heavy power bank, which is plus unwieldy than any flashlight as a torch? The light is not as strong as that in flashlights.
Selling prices are not included in the product evaluation. I also do not do, to me, however, the remark liberty in passing that the Power Bank with currently 40 euros is far too expensive at a capacity of 12,000 mAh. But prices vary from Amazon yes constantly, everyone must keep in mind itself.
I would not hesitate to give the Power of Bank Jackery again among friends.
