10000A Jump Starter, 24V 155WH Car Battery Jumper Starter for All Gas & All Diesel Engines, Heavy Duty Jump Starters, Truck Jump Starter Portable Power Station for Camping, Portable Power Bank (V10-1)

This works excellent for my 40' diesel pusher RV. I ended up replacing the numerous batteries, but this was great when they were having issues holding a charge and I needed to start the rig for one reason or another. It even worked several times without being recharged.

Husband says it works great. Tried it on peterbuilt and worked like a charm.

When using 12V it seemed to work fine, however, definitely not at the rated amperage because it wouldn't even try to turn a semi engine with low batteries which should turn extremely easily at 10000amps. When trying the 24V option it malfunctioned on multiple units. Wires pulled out of the plug the first time it was used.

Wow I thought this booster would be crap but I had to jump my diesel van that need 2 batteries used to have a hard time with a big battery charger starter and using my other van to jump engine turned to slow to start but the booster pack on 12 volts had my engine spinning fast I might buy another to keep in the van

Not too bad

Lithium battery is simply a joke! When I try to use this jumper for the first time it was totally dead after been fully charged & left in the house. I charge and keep it in a climate controlled environment, I placed it on charge and left it overnight again to fully charge it, i unplugged in the morning to see if it holds charge, in few hours it was 100% dead. The second time i try to jump start a vehicle again i left it on charge overnight and used it in the morning, after one jump start the battery level went down to 35%. Now the question is, is the battery used in this jumper really lithium or something else? Why can’t the battery hold the charge?? I personally can make a small box like this for friction of the price this junk is sold for, I do not recommend this overpriced garbage to anyone. I’ll try to reach out to the seller and see if they can replace the defective battery or the whole thing, if one still decides to buy this, make sure you try it immediately so you can return it on time.

Started a Freightliner with week batteries on the first try

The product is fine everything works good but for semi trucks with a completely died battery does not work, not have much power, all semi trucks in USA are 12v so the 24v option doesn’t work for trucks with 12 v
