Ring Ultra Boost 500A Jump Starter Pack Lithium Battery

The Ring Ultra Boost 500A 12V Lithium Jump Starter (RJS010T) is a compact and dependable solution designed to get you moving quickly and safely. Delivering up to 500A peak current, it’s suitable for cars, vans, and motorcycles with engines up to 3.0L petrol or 1.5L diesel.

Built with modern lithium technology, this jump starter is lighter, smaller, and more efficient than traditional booster packs. It also doubles as a portable power bank, with a USB output to keep your essential devices — such as smart phones and sat navs — fully charged while on the road.

For added peace of mind, the Ultra Boost includes safety protection features to prevent reverse connection, sparks, and short circuits. A built-in LED torch with multiple modes makes it especially useful in low light or emergency situations.
