High Quality, Great Value, Compares to the pricey brands!

The media could not be loaded. To start off with I’m a farmer which means half the time a mechanic and fighting equipment not starting. A couple years ago with purchased the name brand booster pack GB150. To be honest it’s been a love hate relationship as warranty has replaced it twice due to issues and just doesn’t perform as we expected. We needed to have another portable battery pack so started looking for alternatives. I came across the Lokithor J401X which is advertised smaller than the one we already have. The price was right so wanted to try it and compare. Pleasantly surprised!!! The build quality is equal to the more expensive but the Lokithor has much better display, light, and charging port options. The battery clamps are high quality tight springs. The screen is bright and easy to view. The led light is bright and nice feature. USB C is much nicer than alternatives. Smaller in size than competitor. This obviously doesn’t matter after first opening booster but the packaging is top notch!! I felt like I was opening an Apple device! Nicely done Lokithor! I will keep testing but currently have jumped side by side, truck, diesel service truck and booster still shows 75% battery. As it stands currently I will grab this booster over the $300 competitors any day. Read more

Starts my excursion with a 6.0 diesel.

Started a 2005 6.0l diesel excursion with a dead battery. To the point where when I released the clamps the excursion died. After putting in a mostly dead battery it was able to start and keep running after releasing clamps. Had to shut it off after charging glow plugs as it will shut off after a few turn overs but once plugs are charger you can turn the charger back on an it will start it. I have to do it 6 times due to changing batteries and it still had one of four charge bars. I was impressed as i have not seen one if these that can get our excursion started after sitting for a few months. I put a dead battery in it on purpose to test. (First battery had been sitting for years) 2nd was actual excursion battery. I wish the clamps were not so cheap feeling but they have not broken or anything. Charges back up in a few hours.

Failed after one use and one year old

Wanted to charge the unit, but not matter what method I use the unit will not power on. I've only used it one time. It's about a year old. I was charging it every couple of months to keep it charged, but it will not longer work. However, the company contacted me about the problem, and was able to get the issue resolved. Read more

Jump charger starts 6.7l diesel with ease

This thing has saved my rear more than a few times now. If you’re considering one of these, I can only say do it. This has effortlessly started my 6.7L diesel when the battery didn’t have enough oomph to do it. Read more

Starts good. Seems to hold charge. Pain to carry.

Seems to start things pretty good. In one day I used it for a rider mower (twice) a 16HP generator that has no battery at all and a 5L Diesel backhoe. Only real drawback is the packaging. The only carrying case is the box it comes in and it is a complete pain trying stuff the cord into its little box, takes longer than jump starting something with it in the first place. Read more
