Jump Starter Car Jump Starter Auto Battery Booster Pack 4000A Peak 12V with USB-C Quick Charge,Lithium Jump Box with LED Light(Up to 7.0L Gas or 5.5L Diesel Engine)

After having this sitting in my trunk for years I finally had to use it. And I'm glad I had the foresight to purchase it. However a few tips for you.1. VERY IMPORTANT: Make sure you charge it up to full battery before you put it in your car! It doesn't start out with much charge, and by the time I had to use it, the battery was completely drained. Luckily I was at home so I could charge it. Otherwise I would have been out of luck.2. How to charge it: use the original cord and make sure you use a wall plug and plug it directly into the wall. This way it will charge quickly. Otherwise it takes days to charge up. Plugging it into the wall, it will only take a few hours.3. Don't leave it on your battery for too long. I think it will charge your battery in a few seconds. I left mine on my battery for a few minutes and it went from 4 LED lights 100% battery to 2 (50% battery) in a few minutes. My car started on the first try, but I had to charge the auto starter back up again. It says it's good for 20 auto starts, so I'm guessing that's only if you prudently unplug it after a few seconds, so as not to drain the auto starter too badly.4. Only use it if the auto starter has at least 75% battery (3 out of 4 LED lights) otherwise the voltage might not be high enough for it to work.Overall this is very handy to have, and make sure you charge it from time to time so it's not draining it's battery from being in your cold trunk. Then you will have 2 dead batteries and be left out to dry.

I got this a couple of years ago and have had occasion to use it recently. I believe I'd tried it originally when the battery was too dead to even light up the instrument panel and it didn't work, but in the past couple of weeks I've started my car several times with this when the battery had some power but it wasn't turning over the engine at all.Started right up! I'm impressed with such a small device starting a car.Its own battery has lasted at least 2.5 years, which is more than I can say for the previous jump starter I had. Very simple to use too.

I bought the jumpstart kit for 3000 amp and it works perfectly. It’s a great value for the money and can be used for multiple purposes like charging the car, charging the phones and as torch.Though my insurance covers jump start but it’s worth buying this at a reasonable price rather than waiting for 1-2 hour for the the towing service to come. I really like the small size and the simplicity in using it.Great product at a good price.

Loved it! This is a handy gadget. Everyone should have one. Great product at a Great Price. I have used it to start a neighbor's diesel truck. I also used it to start my Kubota Tractor. I am not your typical girl. I will be buying more for gifts and an extra for myself.

Great product

This product was a GODSEND and worked perfectly from day one! Its a MUST HAVE if 🫵YOU ever was stuck anywhere due to a bad car battery not working at the wrong time. The size, lightweight compactness of this is great! It was soooo Hard to believe such a small device would possess such a HUGE amount of power. I’ve had battery boosters 4x the this size in the past that didn’t work as quickly and as good as this one. WOW, i was astonished the ease of use and capacity of such a small device possessed. This can be stored anywhere. Very small and lightweight plus easy to use. It features a easy to understand push to start function. No need to be searching for someone to give you a “boost or jump” ever again! This is the GREATEST gift to give someone who owns a car for Christmas or a birthday to have in their car in the winter months for emergencies. Since it’s so small it can be stored in a glove box or even a purse. I give this little thing TWENTY STARS!! 🌟🌟🌟🌟🌟 and I received it very quickly. Kudos to the Seller!

This thing is great! I have had one since 2021, still using it. I was skeptical because these type of jumpers were just coming out. I have purchased a few others for different auto's but none work as well as this one. It holds a charge well also. I would recommend everyone needs one of these. This size is about the same size as a cell phone. Great product!

It’s great with the amount of battery life and the design is so light. The size and build quality of it is shocking because I thought the hard plastic would’ve broken by now from being dropped so many times but it hasn’t and its power is very strong. It’s charging speed is impeccable and it’s very safe and easy to use.
