Powerbank has been a widely used gadget among smartphone and mobile device users.
There are many big companies competing in this space trying to capture the consumer. However, sometimes the small players are the ones who bring in the most well designed powerbanks.
Treqkr50 is a portable powerbank with a solar panel. This back up battery charger can still be charged the traditional way via USB, however you can use solar power to charge it.
The solar charging takes a long time to fill an entire battery, but it works. It charged my Galaxy S6 while I was enjoying the beach.
