S ZEVZO ET03 Car Jump Starter 2500A Jump Starter Battery Pack for Up to 8.0L Gas and 7.0L Diesel Engines, 74Wh Portable 12V Jump Box with USB Ports, LCD Display, Storage Case, and LED Light

This little jump box is amazing! An absolute necessity for your vehicle. Battery life is so much better than similar items. Light weight, easy to use, and comes with a charging cable and carrying case. More durable than similar items. Cable length is perfect for even diesel batteries. Multiple jumps, or charge phones, laptops with this de ice o. A single charge. The only downside is it takes a while to charge. However, it more than makes up for that in usage.

This jumper starter works like a champ. Jump started our van in less then a second and it still had 99% battery life. Would recommend to anybody that might frequently accidentally kill there battery.

I've used mine serveral times this winter with my 3 vehicles. Starts my big 6-cylinder like a champ. My V8 isn't running right now but I can't see why it wouldn't work just as well. A nice thing: I got careless and left my unit in the trunk for 4 months without touchng it. In the dead of winter. When I finally got around to checking it, I found the battery was still 100% charged and ready to go. At this price, it's a serious deal. And the hard case it comes with is better than any othe I've seen. You could drop kick this case across the lawn and I doubt the unit inside would be affected at all.

Update: As luck would have it, I've had to use this beauty twice this week!! Have never smiled when discovering a dead battery before. But now, I just laugh and go for my ET03. Just a-w--e-s-o-m-e !!This small device just removed at 10-ton weight from my chest. No more battery worries!!It's well made, well packaged, and the instruction manual is very well written.You can always tell a lot about a company by reading their manual, if you're lucky enough to even get a manual! The quality of the manual tells me the company cares, from inventing, designing all the way down to the customer population. After a call to the company, I believe this to be true.For those who need a wall adaptor, the manual says the adaptor needs to be >5V, but that's not correct. Anyone who's tried to find a suitable adaptor that's >5 volts goes into a tailspin trying to figure out what to get, and from where.So I called the maker and confirmed that a 5V adaptor is fine, and I can attest that it works great.For those looking to keep this in their vehicle 24X7, I'd think twice about that. Read the manual or call the co. for more info. The severe winter and summer temps, in a closed vehicle, can get pretty ferocious, and lithium batteries are not all that friendly or safe.If you insist, then at least carry a fire extinguisher suited for lithium. Maybe carrying it all in a small styrofoam chest could help maintain a more moderate temp for them.I love, love this product!!

A light got turned on in the cargo area of my small suv when I was moving yesterday and killed the battery. I ordered the jump starter and got it within a couple of hours. It was already at 79% charged but I wanted to be sure it had enough juice so charged it overnight. This morning I tried to start it, and after a little trial and error, it worked a dream. The instructions don’t mention that it will click when it’s working and that you don’t have to wait like other jump starters. If the instructions had been a bit more clear this would have been a 5 star review. I waited a few minutes like I have in the past to let the battery charge, then it stopped clicking and I tried to start the car. It tried, but just didn’t have enough juice. I reset it and tried again, this time I hit the starter immediately after hooking up, and it started right up. The charge is still at 100%. It literally took almost nothing to jump my car. It fits in the glove box, and the price was great for the peace of mind of having it right there if it’s needed.

I bought this in November of 2023 (17 months ago) and just used it for the first time today. I charged it once when I bought it and never again. My wife’s car battery died and this worked like a charm. I was skeptical but the car started right away. Couldn’t believe it. For reference, the car is a 2017 AWD Toyota Sienna minivan with a 3.5L V6. Every car should have one of these. I’ll probably get a second one for my car. This thing is a life saver and incredibly easy to use.

This is great and my 16 year old daughter can use it on her car in case of an emergency. She knows how and this gives us peace of mind. Her car battery was acting up and this was a great backup just in case.

I order so that I would always be prepared. Didn't think I would really need it but I'm always overly prepared and so thankful I was. I must have left my lights on our something while shopping because when I can out my van wouldn't start. So o grab this little jump start connected it and it started immediately! No waiting no reading a mile long instruction manual. It's way and quick. We have one in both vehicles and even bought one for my aunt!
