Our take on the Lokithor J400 2000A Car Jump Starter

The Lokithor J400 is a 2000A 12V lithium jump starter rated to start gas engines up to 8.0L and diesel up to 6.0L, with up to 25 jumps per charge from its 6400mAh battery. It stands out for a 5.75-inch smart display, ConnectMax clamp detection with LED confirmation, and a Force Start mode for deeply discharged batteries. It also works as a 15W QC3.0 power bank and a 300-lumen flashlight with SOS and strobe. The 7 ratings on record average 5 out of 5, but no price history or store pricing was provided, so there is no basis to judge where its price stands.

About the Lokithor J400 2000A Car Jump Starter

The LOKITHOR J400 is a 2000A 12V portable car jump starter and lithium battery booster that delivers up to 25 jumps from a single 6400mAh charge, starting gas engines up to 8.0L or diesel engines up to 6.0L. Built with 80C high-rate lithium polymer cells and an intelligent BMS, this car jump starter uses ConnectMax technology to auto-detect clamp impedance and optimize power transfer, with LED indicators confirming a secure connection before ignition. A 5.75-inch smart display shows real-time battery level and operational alerts, and Force Start mode revives deeply discharged batteries. Ten safety protections—spark-proof, reverse-polarity, short-circuit, reverse-charge, over-voltage, over-current, over-load, over-charge, and low/high-temperature—keep connections secure from -4°F to 122°F. This versatile portable jump box doubles as a QC3.0 15W max power bank with USB-A and USB-C 5V/3A ports, plus a 300-lumen LED flashlight with Emergency, Strobe, and SOS modes.

Questions and answers

Is the Lokithor J400 worth it?
It is a strong fit if you drive a large gas or diesel engine and want a display, clamp confirmation and Force Start in one unit. For a small car, a cheaper 1000A-class jump starter will usually do the same job.
Will it start a diesel truck?
Lokithor rates it for diesel engines up to 6.0L and gas engines up to 8.0L. Cold weather and a deeply drained battery reduce margin, so check your engine size against those limits.
How many jumps do I get per charge?
Lokithor claims up to 25 jumps from a full 6400mAh charge. Real counts drop with engine size and temperature, so recharge it every few months.
Can it charge my phone?
Yes. It has USB-A and USB-C ports at 5V/3A and QC3.0 up to 15W. The 6400mAh battery gives roughly one to one and a half phone charges.
What is Force Start mode?
Force Start overrides the safety check so the unit can push current into a battery too drained to be detected. Use it only when normal starting fails.
When is it cheapest?
No price data was provided, so no cheapest period can be identified. Compare current store prices before buying.
