AVAPOW Car Jump Starter, 4000A Peak Battery (for All Gas or Up to 10L Diesel), Portable Booster Power Pack, 12V Auto Jump Box with LED Light, USB Quick Charge 3.0

I have an old Generac generator that we use when we have power failures or other things happen and try to remember to start it every month or two to keep the gas clean and make sure everything is going well. The last few times, it is really slow to start and pulling the thing to start is a nightmare since it is so big! Instead of replacing the battery pack, I decided to spring for this for just a little more. The generator has the connections to jump start right near the push button, so it is a breeze to hook up and it cranks way better than the battery pack that I bought a couple of years ago ever did! I am looking forward to having this to be able to jump all of my devices that have starters as well as for backup power in case we need it. It seems to have great safety features, after cranking for a while (since I turned the choke the wrong way) it shut off the start ability for just a second. I let off the button on the generator and the pack reset itself and was ready to crank again in about a second and a half. I love that it has a case that is big enough to keep all the parts in, I have a habit of collecting random cords in boxes, so my life is miserable when I need to find stuff sometimes. I hope it holds up to use and storage, just remember to charge it as soon as you get it, it showed four out of four bars, but when I plugged it it, it charged for a couple of hours while blinking the last light. I hesitated to buy this, thinking I wasn't sure of the technology or if it would have the power of a regular generator battery but it has won me over in a big way! Edit: I was using it to charge something a few weeks ago and it completely locked up. I let it sit for a few hours and it still didn't work on either the USB ports or the battery terminals. The terminals would start but would click and act like there was a short circuit within a few seconds, only allowing use for a very short time. I contacted the seller, they got right back to me, but I had left for a trip. When I got back home, I tried it and it worked perfectly. Apparently, it needed a bit more time to reset! I appreciate the quick response from the seller and I have now used it to charge a camera, a phone (multiple times) and jumpstart a truck without any hiccups at all. I still think it is a great product - just the right size and weight to be in my truck all the time. I don't have any hesitation recommending this for anyone since I know the seller backs it up with fast support response and stands behind their products.

If you have ever had the need to jump start your car, the anxiety of hooking someone else's car to mine, always made me nervous. I never knew if the person was hooking it up correctly. And if not, what happens if their car messes with my cars electrical system - it could fry the components. And conversely, what happens if when you start your car, YOUR car sends a surge through theirs - now you just thanked a helping angel with future car issues. This power bank and jump starter, solves all of those issues. After having it in my car for less than a week, I used it to jumpstart my car, my tractor, I charged my phone from zero, and then a friend needed a jump the next day. One charge handled all of these uses. I fully charged it the following day- but I am not sure it would have needed it. This power bank will start basically any car or truck with its amperage and standby power. I am very happy with this purchase. Pros: 1. Outstanding power. 2. Ease of use 3. Includes a cigarette lighter receptacle - (making it possible to inflate tires, or power a radio, or anything else that might utilize a cigarette lighter plug/cord.) you don't have to plug it into your car - always a plus. I can't tell you how many times an air pump would end up blowing a fuse. 4. Really nice carrying case. (easily stored in trunk) Cons: 1. Doesn't come with a USB3 power brick (it does come with a USB2 to USB3 cord). I have a ton of USB3 power bricks, so it's no big deal for me, but if you don't, you might want to pick one up. I don't think using a computer USB3 would be a good idea - it would probably work just fine - but for me - nervous. 2. Doesn't come with a wall plug. This would be a nice addition. 3. My neighbor keeps asking to borrow it. Overall: I really had a hard time coming up with the cons on this purchase. I will update the review if any issues show up later down the line. I am hoping for this device to remain fully functional for the next 10 years. Optimistic? We'll see.

My daughter called during a really cold winter day and said she was at the store parking lot with a dead battery. In the past we would have had to maneuver our car close to hers so the jumper cables could hopefully reach and then try to remember that attachment sequence. But now I had my AVAPOW. We just popped the hood, attached the AVAPOW and started the engine. I wasn’t surprised at how well it worked. The AVAPOW feels solid and well-constructed, and it works even in sub-zero temperatures. We were so impressed that we’ve since purchased two more AVAPOW jump starters so everyone in our family has one in their car. None of us will go through another winter without an AVAPOW in the car.

This thing is a power champ. I was skeptical at first, especially for the price. This thing has severely impressed. Me and I would highly recommend this jump box if you are looking for something affordable and of surprisingly high-quality.

We have had this 3 years and have used it 5 times its always charged. Today we tried to jump a battery and the whole thing shut off with no lights on or anything and now it wont charge. I wanted to update, the company did reach out to us and did everything to make this right. They were persistent about working with us to get this fixed because I had not seen the email until like 3 weeks later it was in spam but in that time they emailed three times urging us to communicate with them to correct the issue. they offered money back or a replacement. We took a replacement. I have never seen a company go so far out of the way to get in touch with us to fix the issue.
