You can charge the SunChargers Festival Solar Power Bank 4,000mAh outdoors in the sun, so you'll always have power for your phone. Thanks to the sturdy rubber casing, the power bank is resistant to drops, bumps, dust, and splash water. This is ideal for outdoor use on holiday or at a festival. You can recharge your phone about once or twice. On top of that, the 2 USB ports let you also help out your friends by charging 2 phones at the same time. The LED lights show you how much energy the power bank has left, and whether there's enough sun to recharge it.
Note: This power bank comes with a micro USB cable. Check whether your device has the same connector. If not, make sure to add the proper cable for your device to your shopping cart.
