Ronix® PS-985 Heavy-Duty 8000A Jump Starter with Twin-Cylinder Air Compressor

I’m a repeat buyer of the Ronix jump starter and couldn’t be more satisfied. I purchased this one mainly as a backup for our second car because the first worked so well. I’ve already used it twice: once to pump up a tire that was a little low so there was no need to go to the gas station, and once to jump-start the car after the kids left the lights on in the back and the car was in the garage for a couple of days. Both times it worked exactly as expected — quick, easy, and reliable. I’ll probably watch a few videos when it comes time to actually use the tire repair kit, but everything else is super simple and intuitive.

It really does what is described. Amazing product. Helped me when my tire got deflated, helped me when my battery was drained. Its really a genuine product. Battery is amazing. Like i charged it 2 months back and still today it was able to do my jump start.

At first I thought that the cables were too short, but they work fine. It starts my F-250 with no problems. I also use it to field charge a dump trailer where there is no other power source.

Back Ground: I bought this yesterday because I had a car with a battery so dead, not even the warning alarms sounded when I got in. It had been dead for a couple of months. Now, I have a regular jumper which is a Li-Ion battery in a case. I had hooked it up, and let it sit for a minute. No Luck. Tried a long time charger, no luck. Damn, then I recalled my sister who lives in the next town over had a jumper she swore. I called, she came over. At first we did have to recharge her jumper, and it took all of like 5 minutes, and we go out to the car, hook it up. She looks at her watch and says Wait one minute. Then she tells me to go start the car. I am like "You're joking me?" Nope, so I got in the car, (still no sounds) put the key in, (Still no sounds) and then I turn the key.

It was like that battery had never been dead. Instant on, everything as the engine rolled over and started on the first turn of the key. Now that alone is worthy of praise but then I asked her "how long do I need to keep the car running, she "I don't, I only to jump once in a while." So the Next morning I come out, and go to the car and guess what. It still started like it was never dead. Two other jumper boxes failed completely to even get the warning bells and dashboard to light up. This one, jumped the car and it runs like it near had a bad battery.

Ergo, while I didn't use my box (as I didn't one) I used hers, and she has had for a couple of years and it has never failed her. Also a friend of hers, who originally owned it, gave it to her and he bought the one that can Jump Start a dead diesel engine battery. Note: There are more jumpers all over the place, even by this company, so if you have a bigger vehicle, check the numbers and get one for your car or bigger. I have seen Tow Truck Drivers carry a similar one, and it jumped a Chrysler 200 that has been dead for months due the electrical short that kept draining.

Not Cheap, but also with that kind reliability, you don't have to worry about being stuck in the middle of nowwhere, and as bonus it will jump 20 cars on a single full charging itself.

Super easy to use jump starter and air compressor. It combines a powerful jump starter, air compressor, emergency light, and portable power bank in a compact package that is easy to store in any vehicle. I felt sick sitting stranded with a flat tire on my side by side in a cow field and waiting for my husband to bring me his compressor. I've used this Ronix jump starter with air compressor a few times already, and it has worked perfectly every time. Definitely a very useful tool to keep in your vehicle for peace of mind!

Works well

Could not have picked a better jump starter. My baby go to work.

Great product. I use this jumper professionally as a mechanic and I can jump several completely dead vehicles with this jumper on 1 charge. I had one for 4 years before needing to buy another one and I’m not mad about it cause I use it almost every day !

Not only a jump starter but also a tire pump, flashlight, portable charger for your devices,it has everything you need to get rid of any problem that may arise when taking a road trip. I can fully recommend the Jump Starter well worth having one of these in every car The battery has a large capacity, making it ideal when traveling or even during prolonged blackouts.
