Recently, I discovered a product that has finally matured to point that it is worthy of cracking open your wallet and parting with a few hard-earned greenbacks. Portable solar panels and battery packs, have finally progressed to level of durability, size, and most importantly, longevity that make them a must-have item. The SunJack 14W +8000mAh Battery is a product that should be in every household, car, backpack… you name it. Don’t get too hung up on the name. The engineers at SunJack spent their time where it would do you the most good—engineering, not marketing.
