If you’ve never had the pleasure of getting stranded in the middle of nowhere because of a dead car battery, take it from me: you’re not missing anything. Jumper cables will help you out of the jam only if there’s actually another car to provide the juice.

With Bracketron’s Road Boost XL portable jump starter, you’ll never get stranded again. At least, not because of a dead battery.

Road Boost XL - Rechargeable Portable Jump Starter / Backup Battery

Road Boost XL – Rechargeable Backup Battery Functionality

The compact gadget is roughly the size of a full-size laptop battery (because that’s basically what it is). It features a powerful, 12,000 mAh rechargeable battery capable of jump-starting most cars, trucks, and SUVs with 200A-400A output.

It also features a built-in LED flashlight with blinking and SOS modes to alert fellow motorists and roadside assistance. A 2-amp USB port means the unit serves as a battery bank for your smartphone or tablet.

The package includes the Road Boost Jump Starter, compact set of jumper cables, AC and DC chargers, and a nylon carrying case.
