Jump Starter - 4000A Jump Starter Battery Pack for Up to 10.0L Gas and 8.0L Diesel Engines, 12V Portable Car Battery Jump Starter Box with 3.0" LCD Display (Red)

I'm losing count how many times I've used this item - for me, and for several 'others'. It's so easy to use - even for this Senior woman ! It's fail proof.A couple men even said - they were surprised and greatly impressed that 'that little thing really got the job done' ! Charges by a C-port charge cord (included) - like the kind used for your cell phone. It holds the charge for a long time, too - even through the cold winter temps. It has a bright flashlight function. And, it can be used as a charge pack for your phone, too ! Best investment, EVER ! Couple it up with the same type Tire Inflator, and you'll have half your Roadside issues under control !

Loved it. Keep in my trunk and have used it on my car and others. Super easy to use. No more waiting for help.

I purchased the AVAPOW 4000A Jump Starter for my son’s car at college, and it’s been a fantastic investment. Its compact size makes it easy to store in his vehicle, and the powerful 4000A peak current ensures he can jump-start his car without assistance. The built-in 3.0” LCD display provides clear information, and the additional USB ports are perfect for charging his devices on the go. It’s a reliable and convenient tool that offers peace of mind for both of us.

I found out that the item was warranted for 180 days, the Amazon 30 return had ran out already. I contacted Amazon and told them about it -- and they offered to send email me a Shipping Label for a return and refund. After speaking with the Seller and being so nice I would like to modify my 1st Review -- All is Well Now. I guess i just happen to get a Lemon.Does not work for Me...Just a Paperweight now. I just now opened the Box today, since I needed to jump my small Kubota Tractor -- IT DID NOT WORK. and it had a 98% charge on it. Few days later I tried using it on my Polaris and did not work with it also -- Will never purchase this Model ever again... (Update) I did get a refund even thou it was 30 days past Amazons Refund Policy --- The company who produces this model stated in their Description it has a 180 day Warranty, and it had not been that long yet since i purchased it. So Amazon sent me a Return Shipping Label, So that was nice of them.

Great product. Everyone should have this as a tool in their vehicle.

Got for lawnmower works great

Hadn't driven my car in 6 months, battery was stone cold dead. I was unsure if this would work, but it cranked it right up. I was able to use 8 more times and it only dropped to 51%. Very impressed!

I ordered this battery charger in February 2025. I had no need to charge a battery until recently. The charger failed to start my son’s small Nissan pickup. His battery charger worked perfectly. Of course, the window to return this charger had long passed. However, the seller reached out to me and offered to send a replacement charger. And it arrived very quickly. I’m in search of a battery that needs charging so that I can try it again. So, the 4 stars is because I haven’t had a chance to use it yet. But the customer support was quick and flawless! If it starts a vehicle, or mower or side by side I will go 5 stars.
