Lokithor does it again!!! I’ve got battery boosters like my wife has shoes! Working around the farm, landscaping, and snow removal we always have a need for a battery booster. I have tried several over the years starting with the expensive name brand ones. I slowly transitioned to other brands and have been stuck on Lokithor for some time now. The quality of these units speaks volumes when comparing to others. Tough, compact, heavy gauge wires, bright displays, long battery life, solid feel all come with Lokithor. This J400 unit is my smallest most compact booster to date and I love it! Easily fits in the glove box of my wife’s car or toolbox on the atv. Weather seal connections so I don’t worry about the elements and its tough outer casing it can take a beating. The new displays on these are even brighter yet in the daylight and easy to read. They have added all the troubleshooting codes on the back on unit which is nice when tackling a bad battery or poor connection. The new J400 has indicator lights showing good positive and ground connections which is really nice! USB-C charging along with standard USB connection. I’ve used the J400 now on small vehicles such as ATV’s but also it will hold it’s own on larger diesel motors on the farm. Very versatile unit and extremely happy will keep buying Lokithor products!

5.0 out of 5 stars Worked great on my truck
Reviewed in the United States on August 4, 2024
I have a 2017 Ford Expedition that still had the original battery. The battery completely crapped out today out of nowhere just like BOOM.... CRAPPED, it would not hold a charge to start the truck after being on charge for a couple hours. I bought this for my daughter to go to college with and since she hasn't left yet I still have it. I turned it on and pushed the top right button just above the light button because I read it bypasses all safety features and gives an extra boost. Well for what it's worth it started my truck up like I had a brand new battery in the thing. Well worth it. I feel better knowing my daughter will have this in her car for back up while she is away.

5.0 out of 5 stars Work’s extremely well…
Reviewed in the United States on August 13, 2024
My old portable booster died after one use.
I bought this version and after fully charging it, I put it in my
Titan 4x4 and not two days later, the battery died.
Pulled this baby out, hit the boost button after connecting the well-made clamps,
and my truck fired right up! Hardly used any stored power, so I’m sure this device
would be able to jump a few cars before needing a recharge. ????

This unit comes partially charged,enough to jump a Honda Accord that hadn't been driven in a couple months, Simply connect the positive and negative leads supplied ,to the car battery and instantly start up.
A must have car accessory!

5.0 out of 5 stars Works well, compact
Reviewed in the United States on July 9, 2024
This is about the 5th jumper pack I've owned in the last 15 years or so. I tend to have to replace them normally between 3-5 years due to heavy use.

This one works well as intended. I was able to start up my dead lawn mower (ride on) and my dead Ford expedition.

Overall, a great value for the money and recommend people to buy one and keep it in your car for a rainy day.

I love the size of this thing. It will be great to bring on trips when size is a constraint. It works great, Ive been using to it jump equipment. Has an override feature so it can jump items with completely dead batteries.
