I don't write many reviews but this Lokithor went through the warranty process like a hot knife through butter. I ordered this October 2024 but didn't get to use it until November 2024 at wich time Amazon doesn't do returns (it was still working so didn't need to return). I had it charged up, used it on a three week trip December through January mainly on-road motorcycle but some off-road. Got back, topped it up with charging cable, and put it on shelf in the house until March 3rd, 2025. Put it on charger with no response. Sent Lokithor an email to see if they could send new battery. They asked for receipt proof, pictures, and short video which I did and they shipped out an entire new unit almost overnight. New one works. If it doesn't last, it's at least comforting to know they'll warranty unlike so many other places that make you fight to get through their warranty proecess. Thanks again.

I have just got through using it twice to jump start a MF 135 diesel tractor that had an old /totally drained battery.It didn't stagger a bit and jumped the tractor within 1-1-1/2 seconds and did it in a powerful/strong/solid manner.This thing is really impressive and I just hope that it gives me this type of performance for an acceptable amount of time (i.e...long enough that I feel I got my moneys worth).As of now, I'd recommend it to all my friends/relatives.NOTE...the only "Ah Man" moment about the purchase was that within 1-2 days of receiving it, I saw that it had went on sale for 33% off the original price I paid $89.95...it dropped down $30.00 to $59.95. I really wish that the vendors (not necessarily Amazon) would honor the discount/sale price, especially if it goes down while the item is in transit to your delivery address.

I used mine for my lawn mower--the mower refuses to hold a charge no matter what, and when as a dad, when i actually have time to mow, it needs to be DONE, so no messing around. Dead mower would mean i'd miss my window waiting on the tricklecharger. Not now. I keep my Starter charged and waiting and if the mower acts up, well, I'm READY for it. It's just a really cool device, does what it needs to do, and has bonus features like usb ports and a flashlight.

Unit looks like it can perform well. The battery clamps are very large which will make them easier to clamp on my truck posts. My only con is that it doesn't come with a storage case...:(

A very versitile energy pack. The first time I used it to "jump start" something, I was really impressed. That old motor cranked faster than it ever had! In inclusion of the light and charging ports for phones, etc. is also a plus. I am very happy with this purchase.

Small bit powerful

Best investment I have ever made. Makes it so easy to jump start your car. I am elderly and the clamps were easy to use with my arthritic hands.I bought a second one for my daughter.

Perfect product! Already helped me many times. Recommend
