Jai tested this product in adverse conditions. Putting themselves in the situation of a hiker who goes several days alone with his equipment and a smartphone will probably need to recharge it especially sil uses their phone to listen to his favorite music. Sil uses Bluetooth headphones its energy needs will be all the more important. I tried to charge my phone very overcast thinking put the charger in check. Well no, it has successfully loaded the device 12% enough to spend a call.
Jai wanted to experience the dune external battery charging (PowerBank PB-17). Given the amount of energy to be stored in this small box sen the charging time is extended. Admittedly, current lensoleillement does not facilitate the test. Limportant charger is that it meets the needs of the hiker for pleasure and safety. One can imagine that he will load his camera during the day with its solar charger that he can hold on to his backpack ugly four carabiners supplied with the charger. The interest of having an external charger is to avoid falling out of energy. The mobile phone still to reach.
This is simply stunning.
