For me the test of this product has been very complicated. I wanted to charge my Iphone and despite several attempts, it is true that the sun of the East in early March was more powerful, nothing worked. A message is displayed stating that my camera was not supported by the charger ...
After a very quick exchange mail with customer support, a second product was sent to me. We can therefore conclude that Ravpower is a serious company.
Retry and new message and miracle, two hours later, my iPhone was fully charged!
Note in passing the Ismart technology to prevent damage to the battery of your device by any excessive charging.
In use, it is rather an exceptional product. He finally effective (for the Sun) but even if the panels are folded very well it's a little bulky in my travels for use behind the glass of the TGV eg. It does not replace such a booster battery.
I would recommend it rather as stated in the presentation of the product also in emergency or extreme that is not my Paris-province trips.
