LOKITHOR J400 Portable Jump Starter for Upto 8.0L Gas & 6.0L Diesel Engines

I picked up the jump pack just in case my truck ever died, and guess what happened after 2 months? it worked perfectly right out of the box. This thing packs a serious punch with its 2000A peak current – it fired up my 6.5L diesel without any hesitation, and the product claims support up to 8.0L gas or 6.0L diesel engines. The ConnectMax Tech made the connection super safe and foolproof; no sparks or worrying about reverse polarity. I picked up the LOKITHOR J400 Portable Jump Starter after my truck battery died in a parking lot during cold weather, and it worked perfectly right out of the box. This thing packs a serious punch with its 2000A peak current – it fired up my 6.5L diesel without any hesitation, and the product claims support up to 8.0L gas or 6.0L diesel engines. The ConnectMax Tech made the connection super safe and foolproof; no sparks or worrying about reverse polarity. For the price (especially with any deals), this is way better value than calling a tow truck or dealing with sketchy jumper cables. Highly recommend for anyone who drives regularly or travels – peace of mind in a small package. Five stars, no regrets!

I’ve been using the LokiThor J400 for about a month now and I am genuinely blown away. In that short time, I’ve used it 2-3 times on my own 1997 Jeep Wrangler (Dealing with electrical issues.) Ive even helped two strangers get back on the road with dead batteries. This thing is a lifesaver — literally. This unit is barely larger than my hand. I expected something bulky and awkward, but it sits effortlessly in my glove box and weighs almost nothing. You can feel the quality in the weight. The connections are rock solid and the build quality is exceptional. No sketchy clamps, no questionable wiring — everything clicks into place with confidence. It's very straight forward, you plug in the positive & negative clamps and you're good to go. It fired up my Jeep every single time without hesitation. It is also a serious portable power bank. I’ve charged my phone multiple times on a single charge — it has more than enough juice to keep your devices powered up on long trips or during emergencies. Battery life is good. If you want compact size, reliable connectivity, genuine safety features, and ease of use all wrapped into one powerhouse device — this is it. Best purchase I’ve made all year. 10/10 would recommend to anyone who drives a car.

I love this battery charger! It works perfectly and is small and compact. Keeping it charged every few months gives me piece of mind if I ever get stuck out and about. It’s difficult as a woman to wait for a stranger to assist with car issues alone. It charge really quick and started my car instantly. It works exactly like jumper cables super easy without the hassle of needing another vehicle. It’s also convenient to not need your car in a certain position to use like needing another car as well making it much more version than standard jumping cables. It’s really well made and seems to be built to last.

Fantastic jump starter! The J400 is the perfect combination between price, quality, and features. The USB-C out is great for charging up my phone when camping, and tailgating, and the flashlight is a great addition for night-jumps. The build quality of the unit is good, with a good heft to it while not being too heavy and compact. The J400 is super easy to use with only a few buttons and clear instructions when you get it. I'm overall really happy with the purchase and the jump starter!

Great charger. It tells you the car battery volts which is great. It started my DEAD battery that was sitting for a while. Easy to use and it tells you when you have the cables hooked up properly. I also use it to charge my devices and still has power to jump a car. I need to replace my car battery because it loses its charge after 2 days of not driving. So I've been using this a lot and haven't had to charge it. The light is great to actually see what you're doing when it's dark out lol.

Well made, works well. The zippered case is nice, but too small making it difficult to put the cables back in. Otherwise 5 stars.

I bought this and I’m glad I did. If your a women and knows nothing about cars GET IT NOW but don’t make the same mistake thing the big usb is the charging port it’s not I was wondering why it wouldn’t charge for a day but it was me BAHAHAHAH but very easy to use. Came half charged so only 1 green bar not on the screen which is fine it still jumped my car. Did make clicking sounds after the 3rd click “ assuming it was charging it “ I crunk the car I did get discouraged but it WORKED happy about that ! Quality is good , I can carry it around EASY fits in my purse. Cables are small and cute but works , the battery is charging also lol
