The Wolfbox Cordless Jump Starter and Air Compressor Drops to Just $40 on Amazon

The Wolfbox is a 3-in-1 device. First is a 12V cordless car jump starter that can supply 2,000A of peak power. The internal lithium battery has enough juice to jump start a 5L gas engine up to 30 times on a single charge. Cordless jump starters essentially make traditional jumper cables obsolete for most people, since you no longer need the assistance of someone else’s car (or a tow truck) to get you back on the road.

Second is the 150PSI cordless tire inflator and air compressor, which can refill a 195/65 R15 tire from 29 to 36 PSI in just over one minute. If you’re using it to fix a flat, sure you have a tire patch kit on seal the hole afterwards. Like most tire inflators, this model can also be used to inflate other things like bicycle tires, balls, inflatables, and more.

Lastly, the Wolfbox’s internal 10,000mAh power bank can be used to charge up your dead iPhone or smartphone when you need it the most. It has one 15W USB-C input for charging itself, and another 12W USB-A input for charging your devices.
