   I like that this is LiFePO4 because it’s safer but it’s super big for the actual Wh, and the voltmeter is so far off as shown in picture that it wouldn’t jump my house generator battery because it thought the voltage was too high. I had to use another jump starter which worked fine. I did verify it will charge and discharge at 60w.

   This LOKITHOR J2250 LiFePO4 Jump Starter with both USB port types (USB-A and USB-C) = easier to replenish when & where needed. Also, this Jump Starter keeps its charge while stored in a below freezing vehicle as that’s when automotive batteries are most likely to have some low CCAs (Cold Cranking Amps). Was glad to pay the $$ for this as it’s been a real lifesaver….just don’t forget it at home after it’s charged as it’ll work best where needed and not from your kitchen counter when the car’s battery is flat and you’re stuck at the airport’s parking lot.

   I had to use on charger on wife car first week that I bought. It was very easy to use and work first try. Well worth the money

   Jump-Starter worked right out of the box. very nice unit. Battery died on me and car was stranded at home. I decided to buy this for any future issues. Came over 75% charged and started my car with a dead battery right up no issues. Charged up with a 15 watt USBC power adapter in no time. Super nice setup. Came with extra USBA and USB cables along with a cig adapter for car charging. Nice case and connector quality. doesn’t feel cheap. I’m surprised most people want to use Lithium ion and this was the only Lifepo4 battery Jump starter. Lifepo4 is the future. Thanks for making a great product that got me back on the road.

   Worked great the 4-5 times I needed to use it to jumpstart a vehicle over the past year or so, but now has a 201 error code whenever powered on. Battery did not lose charge even when stored for months. Disappointed it only lasted a year and a handful of jump starts; I have tried to completely drain the battery and recharge with no luck. Edit: Lokithor rep has reached out and offered a refund on a replacement device that I purchased, will update review if new device has a similar issue down the road

   Unlike Lithium Ion chargers, these aren’t likely to catch fire if you live in a climate where triple degree temperatures are common. I charged this up when I first purchased it roughly 8 months ago. Having checked the charge every month since. it has yet to lose the charge. Every car needs one of these. It’s a relief to know you don’t need someone else to jump your battery should the need arise.

   Easily jump started my 7.4 liter V8 suburban. Lifepo4 battery is nice to have.

   I used once and then I got a “201 error”. The unit powers up then displays the error and warning light and shuts down. (The error explanation is not indicated in the user guide but according to other model in refers to a charge problem.) Had a bit of a hard time getting the warranty hounoured. Explicitely says 2 years on product page on ezysurvival.com and on website but manufacturer claims it was 1 year. They did admit their error and got refund after filing complaint with ezysurvival.com. You really get what you pay for. Quality 2250 amp boosters are double the price. I got lured by the low price. Buyer beware.
