Solar charge: 5V/200 mAh
Info written on power bank |
Capacity check: I checked the capacity and it was only 5000 mAh, because it charged my device 2 times.(It had also an emergency power for light which worked for 1 hr If only used the torch.)
Solar panel: I put it on sun light for charge, it charged 20% pretty well in 7 days in direct sunlight(compared to other one's) how ever the solar panel is only for putting the battery awake. So it's not meant for charging.Protection against fall: I throw it twice from 2 meter on the ground but nothing happened. The body was quiet scratched though but still it was working.
The lamp: It was very outstanding, It was on for 24 hrs for 3 days on full charge, and it was enough to light a 10 square land. It is very good for emergency situations, if you charge it with solar and put it on sun light, it would work for 24 hrs/4 days.
Mini LED: It also had a small blue LED for other usages, it had a very low light but still quiet good in the fully dark place, it was only enough to wake up at night and go to the kitchen for some water and waking up no body.
Charging: at 700 mAh charge it charged my device (which is 2000 mAh) twice, and when the capacity is full on 1 mAh it did it in 1 and half hours, it was quiet good to charge your device with it.
Weight: nearly 400 g, it was quiet heavy for a 5000 mAh power bank.
Summery:
The company that makes these is from china and of course they are cheating in building these, but if you look at the price, I will find it quiet good to have it.
This power bank is good only for using it's light and charging with solar panel , but charging a device is't quiet good for this power bank, what loved from this power bank was it's light, Solar panel, LED torch, the remaining is pure garbage.
DO NOT charge your phone with this powerbank it has a negative effect on the battery health.
