Car Battery Jump Starter - FlyAuto 2800/1400 Amp 12V 24V Heavy Duty Jump Box, Works with Truck Tractor Excavator Automotive Engine Starter Battery Charger Booster Jumper Box with USB/DC Power Unit

I'm a field service mechanic who works on heavy equipment. This jump starter can easily jump start any of my large pieces of equipment. It works immediately and gives me no problems! This is a great investment! I would recommend it to anyone. It also easily starts any standard vehicle as well. Very versatile.

Great jump pack. Works with both 12v and 24v systems. Starts our work vans with ease. Great battery, a total life saver.

I’m a truck driver. This jump starts both my car and my truck. Wish the cables were about a foot longer but gets the job done. Well worth the money.

Works perfectly for our business! Highly recommend.

When it charge works great but been having charging issues ever since I bought it so that's y I give it a 1 star

an excellent jump start especially for car battery. Just a little on the heavy side

I bought the 24v to start up my freightliner, followed instructions and hooked it up to my truck. It got the lights working and that's about it, fully charged and still too weak to start a freightliner.Tried on 3 separate days to give it the benefit of a doubt.This thing is plain false advertisement, it is NOT heavy duty. Do not buy if you want to avoid a headache, should've just paid $300 to a TA mechanic instead of this useless thing.Edit-Seller reached out to me and offered a full refund so I'm upping my review to 3 stars for the communication and customer service.

Came on time and was nicely packaged. Have used it once and it worked great. Nice having a compact jump starter that can be used on our truck and car. Highly recommend.
