Car Battery Jump Starter - FlyAuto 1800 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

This thing is amazing! You won’t be sorry purchasing it

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.

Have not had to use it for cranking my diesel truck yet, but it is a good source of back up power for phones, computers, etc. Well made and thought out construction and design.

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

First off, it arrived a day early. That's always nice!My F350 has had a problem this year. It didn't want to start. I maxed out my Triple-A card getting jump-starts all winter. This machine started my tired truck cold in two seconds. Why oh why didn't I buy this last year before the cold? Highly recommended.

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.

I use this on my military jeeps. Works great. I also use it on my 12v apps. Works great on those as well

I can’t get it to work. Or turn on. How do I charge it.
