The LOKITHOR J400 is a compact jump starter that stands out for strong starting power and a useful boost mode, with reports of handling deep discharges, dual battery Duramax setups, V6s, and even V8s. The brand also has a long track record of holding up well, and the checkout discount applies as advertised. Caveats include a possible model mix up with the J401, oversized clamps that can be awkward on modern battery terminals, and a voltage readout that runs off. It looks like a handy backup for vehicles, boats, and hybrids when space matters.
Common Questions (5)
It has a boost feature that can help with a totally dead battery, but a fully drained battery below about 8V may still defeat many jump packs. This model is described as strong for deep-discharge situations, while some buyers prefer higher-end packs for truly dead batteries.
Yes. The checkout discount applies even though it may not look like it will at first, and the final price can match the advertised deal when you reach checkout.
It is described as capable of starting a dual-battery Duramax when deeply discharged, and the listing rates it for up to 8L gas and 6L diesel. That makes it a practical option for larger vehicles, though clamp size and battery condition can still matter.
The clamps are very large and can be hard to fit on modern battery terminals with accessories attached. The built-in voltage reading has also been reported as off compared with other multimeters.
A buyer reported receiving a J401 instead of the listed J400, and noted the unit was much smaller than another Lokithor they owned. The low price made them keep it, but the model mismatch is something to check on arrival.

I snagged the 1500A from yesterday's deal for $19.99. Received today. Looks like a pretty good little unit.
Hopefully I'll never use it!
