Cyntur JumperPack Mini
Either your smartphone running out of juice or your car not starting can ruin your day, just to slightly different degrees of severity. Fortunately, Cyntur’s IPX3 weatherproof JumperPack Mini can help in both situations. This relatively compact backup battery boasts a 12,000mAh li-ion cell that rapidly recharges phones and even tablets several times over using its 2.1A USB port. More impressively yet, it includes a set of SafeJump battery clamps for safe and foolproof jumpstarting of most vehicles up to engine sizes of 8 cylinders, with enough juice on a full charge to output up to 25 back-to-back boosts. Else, it weighs less than 1 pound, is also equipped with a 200 lumen LED light for the unforeseen, and holds its charge for up to a year, ensuring it’s always ready when you need it.
