‎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

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.

Works great, nice and simple to use, made from good quality materials.

Super easy to use. Works great. Potable light weight. A must have. Value is amazing.

It worked just fine. On a 2005 Infiniti G35, with a 3.5L V6, it took 20% of the battery to start the vehicle once, instead of the reported ability to start 15 times, I think it’s more like 5, but that’s okay, I recharge it right away and most importantly is it jumps the car with once shot, no hesitation. The added features of small size, ability to charge other devices via USB and USB C, and the built in flashlight made this a product worth having in every car. Just remember to check on it and recharge when needed.

Riding mower wouldn’t start after a long, cold winter. I’m old and have a bad back, and it was really too far to push, especially since it was partly uphill. I ordered this jump starter, it arrived the next day, and worked perfectly. Nothing to set up, just plug one end of the jumper cables into the unit, hook the other ends up to the battery, and mower started with first turn of the key.Well worth the money, will keep it in my car, just in case.

My battery was on its last leg and this was such a relief to have in the car. Easy to use, comes in a nice case with instructions, charger, cables, etc. It was so nice not to have to ask someone for a jump and it worked so quickly! It comes charged when you get it, about 75% battery. Definitely worth the money and peace of mind!

I can just repeat what I said above – “Low cost charger that’s lightweight, works quickly which is great if you’re standing out in the cold and works great unless your battery or alternator are truly dead…(Amazon should hire me to test these products especially automotive do it yourself products because I’m always going to tell you like it is!Thanks!

This is a life saver. My car’s battery was dead and this came in very handy. It is very easy to use, and the charging stays for a long period of time. You can also use to charge your mobile devices. Overall, a great product.

Works really well. My battery in my pickup was dead from sitting for a couple months. I charged this unit the day I got it. It started a completely dead battery just like that. I have used it on another vehicle dead battery on the same charge and it still shows 60 percent. I’m anxious to see how long it will perform this well as many battery chargers only last a year or two. So far so good and it is small enough to fit in the center console box of a late model F150.

Fast charging, and easy to use. My battery needed to be changed, but in the meantime, this jump starter saved me from being stranded many times. It’s sturdy and can also be used to charge your mobile devices. It doesn’t take up much space and has the LED number display to let you know how much of a charge is left.

Got this amazing Jumpstarter specifically in preparation for a road trip that I went on and I actually got to use it. Mainly for charging my phones and other electronic devices but I also happened to come across a family that needed a jump start in a Walmart parking lot. The S ZEVZO ET03 Car Jump Starter 2500A worked like a charm and helped that family get back on the road right away. It has a convenient storage case that everything packs up into and I even got some use out of the flashlight function and let me tell you, that flashlight is nice and bright. All-in-all, this is a quality product that you’ll be happy to have with you just in case.

I’ve had my fair share of experiences with car battery troubles, especially with my older diesel F-250. My new truck has not given me problems so far, but at least I am prepared now! The SZEVZO ET03 Jump Starter is nothing short of a game changer for me in this department.Firstly, the sheer power of this jump starter is genuinely impressive. Given that it’s rated for vehicles with up to 8.0L gas and 7.0L diesel engines, I had high expectations, and it certainly didn’t disappoint. It was able to breathe life into my daughters car battery when she had a problem and was stuck at work after leaving her interior light on. After using it, the indicator showed that it was still over 90% full, so the claim of being able to provide up to 50 jump starts on a single charge isn’t just marketing fluff — it seems to genuinely deliver on that promise.But it doesn’t stop at jump-starting vehicles. It has found its way into my daily life as a portable power bank, too. Whether I’m traveling or just need a quick charge for my devices on-the-go, the ET03 has my back. The dual 5V/2A USB output ports are handy, though I must admit, I did wish for a higher output USB-C port for some of my more power-hungry devices.As if those features weren’t enough, the built-in LED flashlight has come in handy too. I used it at our camp sight and had it on for hours without making much of a dent in the battery.Safety-wise, the 10 intelligent safety protections provide immense peace of mind. I’ve seen firsthand how the smart jumper clamps alert my daughter of any errors when she connects it to her car, making sure that she never face any unpleasant surprises.The package comes complete with a sturdy storage case, ensuring everything is neatly organized and within arm’s reach when it’s needed. With a 2-year warranty to boot, it’s clear that SZEVZO stands confidently behind their product.I also have their 1000A DJS70 model and this one is more heavy duty and a bit larger. I have included a picture of them side by side for comparison. For the slight price difference, I would recommend this ET03, unless a slight difference in size is a large factor. I do use the DJS70 regularly in my backpack as a portable charger and it is small enough to fit in my back pocket, where the larger ET03 model would have to remain in my backpack.In conclusion, the SZEVZO ET03 Jump Starter is a must-have for anyone, especially for those with large vehicles or who frequently travel. It’s reliable, powerful, and packs a ton of bonus features that make life just a little bit easier. If you’re on the fence about getting one, take my word for it — you won’t regret it!
