The Cyntur JumperPack mini is not only here to save your dead phone, but also your dead car battery. Cyntur’s IPX3 weatherproof JumperPack Mini packs a punch with its 12,000mAh li-ion cell that can rapidly recharge a smart phone and tablet several times over. More impressive though is it’s ability to jumpstart your car up to 25 times on a full charge with the SafeJump battery clamps. The Cyntur JumperPack Mini holds its charge for up to a year while it also weighs less than 1 pound and is even equipped with a 200 lumen LED torch to light your night. You can find the battery pack at both Cyntur and Amazon.
