Jump Starter 4000A Peak Car Jump Starter with Air Compressor 12V Jump Box up to 9L Gas 7

The first time I used it was on a cold morning when my battery didn’t even try to turn over. I hooked the clamps on, pressed the boost button, and the engine started right up. No slow crank, no clicking, just a clean start. The clamps feel sturdy and the cables don’t feel flimsy at all. The screen is bright and easy to read, even outside in the sun, and I like that it shows the battery percentage clearly so I know when to recharge it. I charged it with the Type C port and it filled up pretty quick. The air compressor has been super useful too. I used it to top off a low tire and it worked better than I thought it would. It’s not super fast like a big shop compressor, but it gets the job done without any fuss. I set the pressure, turned it on, and it stopped right at the number I needed. I used it again on a bike tire and it worked fine there too. The hose fits tight and doesn’t leak air while you’re filling. It’s nice having the compressor built in because it saves me from carrying a separate one. The power bank feature is another thing I didn’t think I’d use much, but I ended up charging my phone and a small camera battery with it. The USB quick charge port works well and the Type C port is handy because I can use the same cable I use for my other devices. I even used it once during a short trip to keep my tablet alive when the car charger wasn’t working. It’s nice having one device that can do all that instead of carrying separate chargers around. The LED light is brighter than I expected. I used it at night when I was checking under the hood and it lit up the whole area. It has a couple modes, and the regular one is bright enough for most things. I haven’t used the flashing mode yet, but it’s good to know it’s there in case of an emergency. The build quality feels solid. The case doesn’t feel cheap, and the buttons respond well. I tossed it in the trunk a few times and it still looks new. The screen is clear and the compressor hose and cables all fit nicely in the storage bag, so it doesn’t end up scattered around the car. The whole unit feels like it can handle being moved around without breaking or loosening. I also tested it on a friend’s SUV just to see how it handled a bigger engine, and it started it without any trouble. The jump starter didn’t get warm or show any signs of struggling. That gave me a lot more confidence that it can handle different situations. I haven’t tried it on anything bigger than that, but for regular cars and trucks it works great. Read more

I travel a lot and being a woman one of my fears is to be stranded on the side of the road with a flat tire. When I saw this I knew I needed it. Right away out of the box it was almost fully charged. I came with a carrying bag which was nice. The only thing I can really leave a review on is the pressure to fill up a tie and the charging capabilities. As for the tires, it did a good job. Good enough to get me where I would need to go if there was an emergency. It also has charging ports for your cell phones. That also worked great. As for the jump started I could not test that. But if in the future I do use this I will come back and update. Overall this is a great investment and good to have on hand in the car. Read more

Hello all, I’ve used this battery starter twice so far. Once to start my car and once to inflate the back tire on my 2016 Honda Civic, and it worked great both times. It definitely has enough power for my car, which was really reassuring. I’ve tried a similar product from another brand before, and it struggled to inflate the tire on the same car, so I could definitely tell the difference with this one. Overall, I’m very happy with it so far and would recommend it if you’re looking for something reliable for both jumping your battery and inflating tires. Thank you! Read more

So small, so convenient! It arrived 90% charged and has since charged quickly and easily. I love that I can keep it in my car without taking up trunk space, it actually fits right under my seat, which is obviously nice for car emergencies but I also plan to use it to inflate our beach floaties at the lake! So many uses, so small and simple to use, holds a charge, the material feels high quality- definitely would order again! Read more

My mechanic husband was actually impressed. He didnt have high hopes, but was shocked that it actualled worked. I got it because my child keeps leaving doors open or lights on killing my battery. I needed something I could use on my own with out having to call the hubby for a rescue. This comes in a sturdy zippered case for storage. The case is lightweight but seems very durable, and fits everything. The starter itself arrived at 60% charged ready to go, though we put it on the charger to fully charge. The power button is large, the display screen is readable and easy to understand. There is a flashlight, strobe light, and SOS capability as well. There’s ports for USB and US-C cables to charge devices. All of the attachments are well-made and of good quality it seems. It actually does fill tires. My husband was shocked about that as well. The instruction included are clear and easy to understand. Overall, this set seems to be extremely functional for our needs. It seems like a good addition for all vehicles emergency box, and a good value. Read more

⭐️Here’s what I love⭐️ ▫️Right out of the box it’s charged so you can properly test it. ▫️It’s super portable and comes with a really nice zipper, hard case that fits everything. ▫️As far as durability- I’m not sure it will withstand too many major drops, but let’s hope I don’t have to find out. ▫️Super easy to use, even if you never crack the little book open. ▫️ It comes with a phone cord that has both lightning and usb-c, the jump cables, and hose with tips for the compressor. Does this do what it’s intended to? ▫️ I’m not able to test the jump feature. ▫️ The compressor portion works well but don’t expect it to do huge jobs. ▫️ I knocked a star because the initial charge doesn’t get you far. We tested it with this blizzard. Charging an iPhone 14 from 36 to 80%battery drained the battery 20%. I’m going to run the battery all the way out, recharge it and then test it again this weekend. If there’s any change to my review, I’ll definitely update it. Read more
