It brought my old 2012 Prius back to life in just a few minutes after I ran off of the 12v battery for too long. It did the same for my 2020 Hyundai Ioniq Electric after I let it kill the 12v by mistake after forgetting to turn the dash off after an update. I also used this to keep my crappy phone charged while taking the bus after my Prius was totalled and before I got the Hyundai.. This thing is great, I highly recommend it. The display on it will immediately let you know that if you're properly connected or not while trying to jump.

The LokiThor J400 Jump Starter has worked great for me! I have a 2003 Ford Expedition XLT, and the battery keeps going dead, but I haven’t been able to figure out why. It’s like something gets left on, so I now make sure I turn everything off, and I check and recheck everything (all interior and exterior lights, radio, AC and fan, etc.), and can’t find anything still on. After twice having someone with a portable jump starter help me and having it work right away and the battery staying charged for at least two or there days after each time, I knew I needed to get my own portable jump starter, and I researched many options and read and watched numerous reviews. I ultimately decided on the LokiThor J400 because of the great reviews, low price, additional coupon offer on Amazon and because the LokiThor J400 has a manual override; which, I learned in my research is typically needed if the battery being jumped is dead or nearly dead, because many portable jump starters won’t work if they can’t register at least some remaining power left in the battery being jumped. However, a manual override bypasses this feature, which may allow a dead or very low battery to be jumped. I have now used the LokiThor two times to jump my Expedition, and it’s worked like a charm without even having to use the manual override! Also, I really like the look of it, that it’s so lightweight, the cables and clamps are strong and work perfectly, the unit charges quickly and easily, and it has a 1-year warranty!

I have a 2014 Camaro (3.6L) that unfortunately has the Chevy ignition glitch 😩 (the key wont come out for hours sometimes). My battery was again completely drained and I didnt want to max out my AAA privileges and I had to be back at work Monday morning. I ordered it on 12/28/24 and got it 12/29/24. The device itself was partially charged and got to 11.8 pretty fast. It brought my car back to life instantly!! It’s small convenient and easy to use. I highly recommend it!
