The Kinkoo 10000mAh Car Jump Starter Power Bank ($98) is one of those things you wish you had in your car when you get stranded in the middle of nowhere with a dead battery. That is definitely a no-fun situation, amigo!
Super-compact (5.04″L x 3.07″W x 0.6″H) and lightweight (0.77 lb), but powerful enough to jump-start your 3L gas or 2.5L diesel vehicle engine around 15 times on a single charge, the Kinkoo packs an efficient 10000mAh Lithium-polymer battery with a life of 500 + cycles. The device has short circuit, over-charge/discharge & temperature protection, plus an ultra-bright LED flash light, strobe light, and SOS signal light (lasts 100 hours). The two USB ports it features are handy for juicing-up multiple gadgets, which makes this power bank perfect not only for car-related emergencies, but also for everyday use.
