Powerful enough to jump start a SUV, yet small enough to fit in a glove box, this is the most powerful Jumping Jack yet. Capable of jump starting petrol and diesel engines up to 3.0 litres capacity, it can also recharge up to 8 phones, 2 tablets or four 13” laptops too… making it ideal for your next roadtrip, festival or camping adventure.

With 2 USB ports, a mammoth 15,000 mAh capacity lithium battery and multi-function LED torch, it can even charge 2 devices simultaneously. Like every Jumping Jack, the Supermax is supplied complete with 4-in-1 charging cable, combining USB, micro USB, 30 pin and Lightning compatible connections in a single cable. Slot it into the Supermax’s USB port and your favourite devices will be charging in seconds.

The Supermax even comes complete with a wide range of laptop tips, ensuring compatibility with almost any laptop too – excluding MacBooks, MacBook Airs and MacBook Pros.
