Your car battery dying out on you in the middle of nowhere (or anywhere, really), need not be a cause of despair. The Cyntur Jumperpack Mini has a 12,000mAh Li-Ion battery that allows you to jumpstart 4, 6, and 8 cylinder engines. Pre-charged, it’s capable of 250 cranking amps of starting power and even comes with a USB port so you can charge all your gadgets on the go. Compact and portable, it comes in a carry case, small enough to store in your glove compartment, features a built-in bright LED or strobe light in cases of emergency and SafeJump technology that prevents reverse charge and over-current.
