“Speaking of off-the-grid, the Energizer PowerKeep 36 is designed for hikers, boaters, van campers or travelers in the back of beyond who simply need to stay charged and in touch with the world. It’s a portable, flexible, 4-panel, fold-out solar power system that allows you to charge multiple devices while on the go. The power system features a compact 10,000mAh power bank, solar panel and a USB cable. The PK10K power bank can be charged from the sun, AC or any USB charging port and used to power portable electronics such as smartphones, tablets, speakers, etc. A full charge via the solar panels depends on the sun, of course, and takes anywhere from 10 to 20 hours. Once charged, it can power up a phone in a little over two hours. It weighs a bit more than one pound and the retail price is $139.”
