I have a friend who goes off for days hiking and camping in the local countryside and moors, he likes to get away from it all but still likes having his phone and MP3 player with him and needs something to keep them charged. So when I saw this waterproof power bank with a solar charging option I thought this would suit his needs.
This power bank is ruggedly made from ABS silicone and it's stated that it is waterproof which is ideal when taken on outdoor pursuits. it comes with a USB to micro USB cable, a user manual and a sprung clip for hanging on a backpack or up in a tent. The power bank receives it's charge via it's micro USB port and has 2 x USB ports for giving a charge and can charge two devices at a time. This power bank has a large solar panel for trickle charging when away from a power source. The amount or charge received from the solar panel will be dependant on the light intensity and length of time the sun shines so I personally wouldn't rely on charging the power bank this way. The 12000mAh capacity of this power bank should ensure a few full charges of a phone and MP3 player whilst away from a power supply.
There is a built in power meter which uses 4 x LED lights to give an idea of the percentage of charge remaining in the power bank. and another useful thing built into this power bank is an LED flashlight which should be useful when camping. Hopefully this rugged, waterproof power bank will solve my outdoor loving friend's needs. To see this X-DNENG 12000mAh Waterproof Solar Power Bank on Amazon click on the link below:-
