Overview
A roadside shoulder at night is the scene the Lokithor unit is built for, pairing a jump starter with a cordless air compressor in one compact box. Smart clamps connect to the battery, and a screen shows voltage and tire pressure.
Drivers who want one box for a flat battery and a soft tire get both, with presets that stop inflating at the target pressure. The engine range stops short of larger diesels, and the listing gives no weight, battery capacity or warranty.
Who it's for
Breakdowns far from help, from a dead battery to a slow leak, suit the combined jump pack and compressor. Owners of heavy diesel pickups should look at a larger unit.
Pros and cons
- Jump starter and air compressor combined
- Preset pressure with auto shut-off
- Boost mode for fully drained batteries
- ConnectMax compensates for dirty terminals
- Battery capacity not listed
- Engine range stops short of big diesels
- No USB-C fast charging mentioned
Performance notes
Starting power depends on the high-rate battery feeding the clamps, and the ConnectMax system reads impedance to compensate when terminals are corroded or dirty. The compressor stops at the preset pressure, and a balance beam base damps vibration and noise while it runs.

Frequently asked questions
Is the Lokithor JP400 a car battery charger?
No charging or maintaining mode for a car battery is described. It jump starts 12V vehicles, inflates tires and charges devices over USB.
Can the Lokithor JP400 start a fully dead battery?
Yes. Its BOOST function detects battery voltage to help revive fully-drained batteries.
What can the Lokithor JP400 inflate?
Cars, motorcycles, bicycles and balls. You set the pressure on the screen and it stops when it reaches that value.
How does ConnectMax help on the Lokithor JP400?
It detects impedance between the clamps and the battery and compensates for poor contact, which the listing says improves starting performance by 30%.
