Ronix® PS-218 4-in-1 Portable Battery Booster & Digital Air Compressor

Left my headlights on all night and the battery was completely dead. Took this out of my trunk, hooked up the smart clamps, and the engine started in literally 5 seconds! Didn't have to wait an hour for roadside assistance. Every car owner needs one of these.

This jump starter came with simple to follow instructions a clear set of buttons laid out in an intuitive way with icons that makes understanding operation simple. This portable jump starter has the ability to power mobile devices it has a built-in compressor that's powerful enough to inflate car tires bicycle tires basketballs motorcycles Etc. This jump starter also has a flashlight that can blink in intervals in case of emergencies. Also included is a detachable hose that you can use to inflate items. Since this item will not be used frequently I suspect the battery life should be long.

Used it on a 4-day road trip. Not only did it inflate our air mattress, but it also recharged our phones twice via USB and still had over 70% battery left on the digital screen. Build quality feels very premium and solid

I was skeptical about whether a portable unit could crank over my 5.7L V8 Tahoe in the cold, but this thing surprised me. Hooked it up, waited 3 seconds, and it turned over instantly. The digital battery display is accurate and super helpful.

I’m glad I was able to get one of these we have been needing one so bad in our family I would highly recommend anyone get this item as a precaution I did have a halo box for the last few years but my halo never have the tire pump accessory and that in itself is so helpful. I would definitely say this item is worth the money I’ve seen some of these go for a lot and not have all three tire pump, charging station, jumper cables and an emergency flashlight all in one so this is a good deal everyone should have one of these in their car for emergencies. Gift it to someone or hold onto it for yourself this is super important and I highly recommend this item!!

Super funcional!! Me encantó es demasiado práctica!!

As advertised compressor aired my tires pretty fast.light works well and being able to charge phone and flashlights a plus as well as the jumpstart. And it well built.

Excelente. Muy práctico. Bomba de inflado potente.

Handy to have in the vehicle. Airs up tires very well. Like how you can set the pressure and it stops.

Best investment. After charging it I had jumped my car 5 times before having to charge it again. And even then it still has 2 green bars full of battery left. I’m a woman so it’s easy to use, small, lightweight, compact and it holds an amazing charge. I have only had it a few months, but it’s already proven to be worth every penny. Built strong. Keep it off when not in use and it holds a charge for forever.

I’ve gone through a few portable inflators over the years, and this one feels more thought out than most of the cheaper Amazon options. The biggest thing I noticed right away is how much faster it fills tires compared to the small single-cylinder inflators that struggle and overheat after one wheel.

The auto shutoff feature works accurately enough for normal use, and the digital display is easy to read even in lower light. I mainly bought it to keep in the truck for topping off tires during temperature swings, but it’s also been handy for bikes and random stuff around the garage.

Battery life has been solid so far, and I like that it doesn’t feel toy-like. The hose connection and overall construction feel more durable than expected for a portable unit. Noise level is still pretty loud — but honestly every inflator in this category is.

My only real complaint is that the storage setup could be better. Once everything is unpacked, fitting the hose and accessories back neatly takes a little effort. Also, the PSI reading seems to fluctuate slightly while inflating, although the final pressure has been accurate when checked with a separate gauge.

Overall, it’s a useful thing to keep in the vehicle and feels like a noticeable upgrade over the bargain inflators I’ve used before.

Bought this charger for my husband to use in cars, boats or golf cart. So portable! We’ve used it several times with no issues. Highly recommend.

before leaving a review, I wanted to thoroughly test the PES-218. Since purchasing it, I’ve used it to both inflate tires and jump-start vehicles. So far, it hasn’t let me down.

The unit comes in a nice, compact carrying case with several additional air-inflation attachments. The jumper cables are also compact and grip battery terminals securely. Out of the four vehicles I’ve jump-started, three started on the first attempt.

When it comes to inflating tires, you’ll need a little patience. It gets the job done, but it isn’t particularly fast. Also, be aware that the unit gets HOT while inflating tires, so use caution when handling it during or immediately after use.

I keep a bag in my vehicle with items for roadside maintenance & emergencies, and I wouldn’t leave home without this device. If you’re looking for a compact and efficient combination jump starter and air pump, I highly recommend the PES-218.

Arrived in 3 days in perfect condition. Tested the air pump on my bicycle and car tires right away—super accurate pressure readout and stops automatically when it reaches the set PSI. Very satisfied with this purchase!

My car battery has been dying randomly every couple of weeks. This jump starter has saved me at least 4 times already this month without needing a recharge itself. Solid build, high quality clamps, and compact design.

I just used this device to rescue a car with a dead battery and a non-functioning alternator (the device that charges the car battery). It jump-started the car and supplied enough watts to drive the car for about 15 minutes (all I needed). Note: Once the car was running I had to press the boost button every 30 seconds for about 4 cycles to get enough watts in the battery to drive the car (because the alternator was not functioning).

Then, as a test, I added 6 psi to a car tire. At the point the battery was down to 26%, but still had enough power to charge some USB devices and run the light function, but not enough power for another jump-start (but it could still inflate a tire).

I think this is a must have device in every vehicle, especially if you drive on remote or isolated roads.
I cannot speak to longevity, but the device and accessories are of excellent quality.

Everything is perfect, it works well, it's fast.

Works perfectly. Great device for inflating all kinds of things, which can be selected on the display. Display is easy to read. Can recommend it. Thank you very much.

Fast delivery. Assembly is good and of high quality. The screen is bright and clear. All functions work. We'll see how it performs in winter.

This is a product that every driver should DEFINITELY OWN!! I bought one for myself and it saved a call to AAA, and possible hours of awaiting their arrival. It charged up very quickly to 100%. My son was at my house, and as soon as it charged fully, he took it straight to the garage, hooked the clamps to the appropriate terminals, pressed the vehicle’s start button and it started immediately! The 2024 Subaru is a lease, and it had not been driven since before Christmas 2025. The severe sub-zero cold spell in our area snuffed out the battery. We couldn’t even open the door with the fob, so it was necessary to use the fob-key to enter the vehicle. After that, when the charger was at 100%, it took only about five minutes from the time my son walked out of the house until the vehicle was running. Of course, my son kindly drove it around the block several times and left it running for several additional minutes to maximize the charge. When he turned off the vehicle, I was able to get it started with my phone app. We were highly impressed how quickly everything was accomplished. It was extremely easy--peasy! When all was said and done, we recharged the unit to 100% and returned it to its handy-dandy carrying case.

Then a light bulb turned on in the ol’ brain. My son drives by himself to Montana to meet my brother and sister-in-law in August most years. They stay in a lodge and rent 4-wheelers and check out as much of the beauty of Montana as they can crowd into 5 days. Then he drives home alone. Usually, he has strict instructions to call me each time he stops for the night on the way there and back. That won’t change, of course, but it will save his mom (me) a world of worry between his calls. He’s an excellent driver, but things can happen out of the blue when you’re traveling long distances over basically unfamiliar highways. Now, if he loses air in a tire, he can easily fill it until he gets to a place where it can be repaired or replaced. It’s doubtful he’ll experience a dead battery, but if that should happen, it won’t be a disaster.

In all sincere honesty, it would be wonderful if everyone had one of these great products in their vehicle. A tiny piece of advice, get one for yourself and each of your offspring of driving age. You’ll worry a LOT LESS when they are driving. It’s a portable, lightweight, small unit that offers big advantages when the unexpected happens!! You deserve the peace of mind.
