The Lokithor J400 is a compact, 12V cordless jump starter capable of delivering up to 2,000 amps of peak current, making it powerful enough to start engines up to 8L gasoline or 6L diesel. It’s equipped with a robust 8,000mAh lithium (NMC) battery that supports multiple jump starts on a single charge. Thanks to its advanced lithium chemistry, the battery maintains its charge significantly longer than traditional models—retaining up to 80% of its power even after 24 months of storage.
Beyond its primary function, the J400 doubles as a portable power bank, letting you charge your iPhone or other USB-powered devices in emergencies. It supports fast charging via USB Type-C, and both a USB Type-C to Type-C and a USB Type-A to Type-C cable are included in the box—so you won’t be left searching for the right cable when you need it most. The built-in LED flashlight offers three modes: standard flashlight, SOS, and strobe, adding extra utility during nighttime breakdowns or emergencies.
Measuring just 3.4" x 6.9" x 1.7" and weighing only 1.5 pounds, the J400 is one of the most compact models in its class, making it easy to store in your glove compartment or trunk without taking up much space.
