JumpBox | 4120A Portable Jump Starter | 26800mAh Power Bank & USB-C
Description
Boot Insurance With a USB-C Port
4120A of peak output and a 26,800mAh cell in a case the size of a paperback. Enough to turn over most petrol engines and a good number of diesels, with USB-C in and out so it doubles as the power bank you were going to buy anyway.
Why You'll Love It
- 4120A peak output – handles most petrol engines and mid-size diesels without a second car
- 26,800mAh capacity – multiple start attempts, or a full phone charge several times over
- USB-C in and out – recharges from a laptop brick and charges a laptop back
- Smart clamps – reverse polarity and short-circuit protection built into the cable
- Built-in torch – flashlight, strobe and SOS on the same button
