This is a very low-cost 12V jump starter that can handle a dead battery in a pinch, and it has worked on cars, ATVs, and even a V8 6.0. The price has landed around $23.47 before tax for some checkouts, which makes it feel unusually cheap for the category. The main concerns are its very light, hollow-feeling build, toy-like clips, and doubts about the 2500A claim. Clip size may also be an issue in tight battery bays, so it suits short-term emergency use more than long-haul confidence.

  • The jump starter can start a car multiple times in a row when the battery is fully charged.

  • The unit can work for emergency use after a vehicle sits dead overnight.

  • The crocodile clips may be usable for non-car tasks like starting an ATV.

  • The device can function as a 12V power supply for a spot welder requiring very high current.

  • The unit may feel extremely lightweight and cheap, which can lead to returns and reduced confidence.

  • The promo code may not reach the advertised $23 price after tax, leaving an effective discount closer to about $14.99.

  • The crocodile clips may be too large for vehicles with limited battery-terminal clearance.

  • The advertised 2500A output may be misleading because the battery size cannot realistically deliver that current.

I've had a couple different brands (not particularly this one) they seem to stop working. Any recommendations?

Lifepo tends to be safer, less fire prone, and the peak amps matter.
Also lasts ten years instead of 2-3 years in hot/cold cars.

I ordered this and am going to return it. I am very familiar with Lithium batteries and this jumper is super light. I highly doubt it can source 2500 amps.
That's a good point... it is too light. The lightest of the three brands I've bought by a long shot.

Anyone ever use one of these before? There seem to be a lot of brand options, not sure which ones to trust. I'd like to keep a set in my car.
I haven't used these on a car before but they worked magic on my ATV

I've had great luck with two different brands of these. My second one can start my V8 6.0 from a dead battery.

Thank you. I have seen a lot of negativity in this thread, but I decided to buy one after hearing your experience.

I always consider and wonder about how well do these work when you need them to.
