We bought this last week as we were struggling to start our Mitsubishi which sits often and doesn’t get driven. After using jumper cables multiple times we figured we should look into getting a good jumper pack. After reading the reviews we decided on this one.The last time we attempted to start the Mitsubishi it was completely, 100% dead, it wouldn’t even unlock the doors. So this evening I suggested that we go try to start the car with this new jumper pack from a complete dead battery.We plugged it in, hooked it up to the terminals, and pressed power. I use the key to unlock the door which worked! Then turned the key and immediately turned over and started!I wish I would have had a recording of the excitement on my husband’s face because he couldn’t believe it however I knew after reading the reviews that it was likely to work and it did not disappoint!!!Thanks again for making such a durable, easy to use and very reasonably priced piece of equipment. Definitely a great purchase!

This S ZEVZO ET03 jump starter is a great addition to my car emergency kit. It’s surprisingly compact for such a powerful 2500A unit, capable of handling big engines up to 8.0L gas and 7.0L diesel. I appreciate the clear LCD display that shows battery status and other info — very user-friendly. The built-in USB ports come in handy for charging phones or other devices during emergencies, and the LED light is bright enough to work by in low light situations. The included storage case keeps everything organized and protected. Overall, it’s reliable and easy to use, giving me peace of mind on the road. Would definitely recommend for anyone wanting a portable and versatile jump starter.

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!!

I have not needed to use it yet.It seems well made and comes with a nice storage zippered container. The instructions are clear and easy to understand. It was partly charged on arrival, so I charged it fully. I keep in the vehicle, because...The price was right for a bit of emergency insurance.

I love it. This is the only jump starter i could find that told you in the description how much power it was capable of delivering. The other ones gave amps but for how long, 3 seconds???This one gave the power as 74 Wh and that it will deliver 2500 amps. This means it will deliver 740 amp for 6 minutes. That's a lot for a long time.Came with a very nice case too.

I wasn’t sure that I would like it. I thought there’s no way this can start a car engine just from a rechargeable battery. I plugged it in in three hours later was able to jumpstart my 1988 Porsche Targa absolutely love this. !! Very useful

It charges quick and a full charge will go a long way. All you do is connect adapter to charger and cables to battery, press the power button and the charge begins. If your car battery is really dead give it at least 5 minutes before you start your engine. The cables are short but good enough to sit on battery while it jump starts. Also make sure all lights and switches are off, this helps jump start faster. I highly recommend. It comes in a hard secure case, small enough to fit under a seat. Best investment ever. It’s an amazing quick jump start to your car. Automatic, standard, mini van, truck, suv, you name it. I have already helped many with it, have recommended it to many and bought a few already as gifts.
