He did a great cloudy today, yet when I put it by the window, it recharges (it is however say the energy loss between the clouds + glass). After so do not expect it to be done very quickly, and use energy conscientiously accumulated (do not use the 2.1A port for everything and anything in short, since it discharge 2 times faster) .
My battery usage. Feeding a nano-computer, the Raspberry Pi It's just the job, but then I expected no less as it is supposed to deliver 5V with 1A / 2.1A choice. It will also work very well for all who charged via USB (eg cell phone ...).
Another very practical point: In addition to charge via USB, it also recharged via microUSB. We use the same cable for two different uses of the device, and that's cool (a cable is supplied with a whole bunch of adapter, if I had you have an Iphone ... We never know ... ).
Now is the price, which is beyond any competition I think. Less than 20 euros for a battery of this capacity, with a solar charging premium, what more?
And finally the time: As it comes from China (it seems), it pays to be patient minimum. I received mine a little over 2 weeks after order (I live in Normandy just for info), it's still reasonable.
For comparison, I also bought on amazon a 15000mAh battery which cost me 46 euros without solar charging and charging via microUSB port: received in a week. See for yourself if this one is a bargain (for me no doubt).
In short, very satisfied with my purchase the you'll understand. :)
