With the ever increasing reliance on electronic devices, we sometimes forget to charge our devices. Many carry around a power bank to have extra charge for there devices, but if you discharge the bank fully, you run the risk of damaging the battery to the point it will no longer hold a charge. Well with the Solar Power Bank, you can charge the battery the regular way, a micro USB, and discharge it like every other power bank. The main difference is that this power bank can also be charge by sitting it in anyplace where there is a light source. Of course setting it up direct sun light will work the best, but any light source can charge the battery, given it is strong enough to activate the solar panel.
