Upon unpacking, we feel that quality is at the rendezvous. The battery Bumps or rain and it shows. Surprise since the charging green LED lights immediately, even without direct sunlight. So we say that the charging capacity is huge because the day is enough. Since then disillusioned in the instructions it says that 6 to 7 hours of sun allow charging from 20 to 30% of a smartphone. We must therefore rely theoretically 4-5 days to fully charge a smartphone. In addition, it is recommended to load in that when the solar battery is below 75%. Otherwise, it may swell in the sun if it reaches the maximum.
Load side, it has 2 USB ports but only limited to 1A. So, on the latest smartphones, charging will be slower than with a conventional charger. It also has the ability to charge the battery using mains via a micro-USB plug. We can leave with his battery charged and scrounge a few percent with solar charging battery by putting her on her bag-to-back. Side friendly service and increasingly indispensable, the battery has a LED lamp that lights up by 2 clicks. And as this battery is primarily for hikers, it also has a SOS mode that triggers a click when the lamp is on. Clicking returns the lamp mode, while a double-click the cut. Note that the load does not launch automatically when you plug a device. It must go through the on / off button. This also serves to provide information on the status of the battery via 4 blue LEDs (4: 75-100%, 3: 50 to 75%, 2: 25 to 50% and 1 - 25%).
Ultimately, this external battery solar charger is primarily an external battery and solar charger will more anecdotally. However, it still can recover some drums just by solar energy while being very robust and very compact. It appears thus that very few overweight compared to a battery of equivalent capacity while integrating a solar panel which is a technical feat. It is therefore the ideal companion for hikers and other campers.
Pros: - Look adventurer shock resistant and water - Double charging via mains or solar panel - lamp function
Cons: - Solar Charge enough anecdotal ultimately - 2 USB outputs limited to 1A.
