ACMOUNT W160 5000A Jump Starter with Air Compressor 150PSI, 12V Jump Box | Car Jumper Starter Portable(9L Gas/8L Diesel) with Jump Cables, Tire Inflator, 3 LED Light Modes, Power Bank, Car Essentials

Have several. Used each many times, cold Montana winters. They all hold charge for a long time and start everything I've used them on. These are Christmas presents this year for the whole family!

Exactly what I wanted and works like a charm. Received the item with in a few days! Very happy with it.

Super easy to use, has a great case to keep it clean. Come with a USB charge cable, has a light and compass. It cranked two cars up and still have over 80% of its charge left. Super handy and much better than jumper cables. Many times the cables are not long enough, but no worries if you have this Jump Box. Highly recommended. Shipped fast, no issues, super simple that a teenager could easily use it.

My car battery is fully drained, and the battery would not even charge with a charger. Nothing was getting power, not even the power door locks. I was sure I would have to have a tow truck called out. As a gamble to save on that cost (and get the car running to bring into the shop) I bought this. I had a heavy lead-acid battery jumper device, but it did not work. Its battery had run out, and it also could not take a charge. This device started my car instantly, and it is very simply to use. Plug the cables in, connect the cables the battery (red to red, black to black), start the car, and disconnect the cables from the battery. The device has a light on the cable connector that turns steady green when the cables are connected securely. It has a safety check, so it does not spark when connecting directly to the battery terminals. Once it sees that it is getting a good connection, the light turns solid green and you are good to go. The lithium batteries are significantly better than the old lead-acid battery powered jumpers. Not only is it compact and light weight--the batteries hold a charge for two years so you can keep the device in the car and be certain it is ready to use if needed. The lithium batteries can also be recharged hundreds of times. It charges easily via USB-C from a power brick. I just used a 65w power brick that I have for charging phones and running a laptop.

Good jump starter! Works especially well on batteries ties that are slightly dead. It's been 3 years and used it a handful of times. On the latest one, I I had to leave it on for a bit because the battery was really dead. Brought it's power from 100% down to about 15%. Next time I'll buy a bigger size battery to be safe. The only issue I have with it is the build quality. The plastic case makes it feel cheap.

I always had an air compressor that needed tied to the lighter input. Fumbling with a cord was not always fun. So, when I seen this and had battery issues this past winter. I felt like it was a no-brainer to grab. First mow of the season, my tire is flat and thought it would be a perfect time to try it out. Worked great - was fast (much faster then the plug in corded one). I pumped that tired up .... sat on it ready to go... And my battery was dead. Didnt plan on testing that at this time. Was a little difficult to get the adapters on the battery and be able to sit to start it but I managed. First attempt it did not start. However, went back to the directions and it said the light needed to be green. So I unplugged it and plugged it back in... and it turned green. I went to start and - and it worked! So I felt the need to come on here and give a shout out. It's solid, has weight to it... and I enjoy the case it comes it. Keeps everything together. Works like a charm.

Works very well. I have a slow leak in one if my tires and had to use it to pump up the tire so i could drive safely. Used it several times to jump start atranded people.

My Lithium Battery Jump Starter arrived with about 57% charge, so I hooked the plug up to my computer. It took 3 hours to achieve 100%. I took it outside and attached the rather small (but effective) clamps to my car battery, got in and turned the key - immediate power! Forceful and strong, the engine growled and barked with a furious will! My Ford is 26 years old, and I don't drive it much so in winter the battery is apt to go dead. After the engine was powered up, I turned on the windshield wipers and defroster because it had just snowed; this caused the battery to shut off completely. So, with the jumper still at 100% power, I gave it a second jump, and once again, the car started right up with a loud rumble. I left all apparatus off this time, ran the engine then drove it for a couple of miles, let it idle running for another 25 minutes, and the battery is now fully recharged. After two jumps, the lithium pack was still at 99% charge. I recharged it and packed it up. The storage case is nice, hard with a zipper closure, and the cables & clamps have their own netted pouch along with the charging plug. It's a great deal and at this time, I can highly recommend this product. Its compact enough to store in the glove compartment for emergency use. The instructions say to recharge it every 3 months. It's really an impressive little powerhouse of rescue equipment that every driver should keep in their car. You never know when you'll need it, especially in winter when batteries often die on parking lots at stores or after your long shift at work. Once I had to wait alone over an hour and a half for my roadside assistance to get to me on a dark lot because they'd received so many calls that cold winter day. This is a scary prospect, as the office had already closed and it was the days before affordable cell phones. For the price, this is a great piece of equipment and a must have for single women!!! Would also make a thoughtful gift to anyone whose safety you care about.
