GOOLOO A3 12V 3000A Portable Jump Starter with Air Compressor

We spend a lot of time in Baja California, and rough, unpaved roads result in lots of tire punctures. Having a decent air compressor is therefore "necessary equipment".This unit inflates tires reasonably quickly, automatically displays the pressure in the tire before you set the desired inflation pressure, and shuts off automatically when the desired pressure is reached. The display is easy to read. The short, detachable hose is easily attached and removed, and stores in the bag with the pump. The hose length works for most common automobile tires, and will work for oversize tires by rotating the wheel to bring the valve stem closer to the ground. Attachment to the valve stem is easily accomplished with its lever-lock working end.The unit can additionally function as a battery booster for starting a vehicle with a low battery. Installation of the cable for that purpose is easily done, and it worked just fine when we had to use it on one of our two vehicles one morning, allowing the car to be started quickly and easily.Charging is accomplished with a standard USB charging cable (USB-A style at one end, and USB-C style connector at the other end). We had a puncture that required the pump to be used multiple times to get the 12 miles back to a tire repair shop. We could charge the pump up easily and quite quickly via the vehicle's USB port, stopping every few miles to pump the tire back up enough to keep going on the highway without having to go through the trouble of unloading the trunk to change the tire for the "doughnut" spare at the side of the road.Having those two experiences just shortly after we received the pump was more than enough proof that we should have another for our other car. I'd recommend it for its small, easily stowable size, good battery capacity and ease of use.

I bought this in 2025 and it has been great for checking tire pressure. It's very fast and light, unlike my old, heavy compressor/charger. It seems like I'm always having to replace valve stems so this is a must have for me.I finally needed it for a dead battery. I tried my old Duralast first because it was fully charged, but I couldn't get my car to crank even after leaving it for half an hour. The next morning I tried THIS charger and tried it almost immediately and it cranked right up. I then drove to get a new battery.This one was MUCH cheaper and better quality than the ones I saw at local stores.

I've been wanting to get one of these for a while now that way if my battery ever dies I can give it a jump without having to flag someone down to help me out. I saw a video on YouTube by "project farm" where he tested a different jump pack from the same brand and it did extremely well in his tests so when I saw that this one was on sale I bought it immediately. I have no regrets with my purchase. First of all I love that this comes with a case and everything fits in a nice little package that doesn't take up too much space. Having a built in flashlight and air pump are also nice. I forgot to turn off the auxiliary power in my car when I came back in from my lunch break at work the other day so my battery was dead by the time my shift was over. This thing jump started my car like it was nothing. Just hook up the cables, hit the boost button and start the car. My car didn't even hesitate. It started up like the battery was never even drained in the first place. I also used it to inflate 2 of my co-workers tires. It has come in handy so far. If you want a good jump pack for under $100 this is a very good option.

★★★★★ Outstanding Product Backed by Outstanding Customer ServiceI purchased two GOOLOO A3 Jump Starters with Air Compressors for my family vehicles, including a Toyota Sienna and Hyundai Palisade.The unit itself is packed with useful features. It combines a powerful jump starter, air compressor, emergency light, and portable power bank in a compact package that is easy to store in the vehicle. The air compressor is simple to use, and having one device that handles multiple roadside emergencies is extremely convenient.One of my two units unfortunately developed a defect and began overheating. While that was disappointing, what happened next is why I am writing this five-star review.I contacted GOOLOO customer support and was assisted by Fiona. She responded quickly, took the issue seriously, and worked with me throughout the entire process. Amazon ultimately determined that the defective lithium battery unit should not be returned because of safety concerns and advised proper disposal.Without any arguments, delays, or unnecessary back-and-forth, GOOLOO immediately arranged a replacement and shipped it directly to me. The replacement arrived quickly and has been working perfectly.In my experience, the true test of a company is not when everything goes right. It is how they respond when something goes wrong. GOOLOO stood behind their product, communicated professionally, and resolved the issue promptly.I have dealt with many companies over the years, and the level of after-sales support I received from Fiona and the GOOLOO team genuinely impressed me.The product is excellent, and the customer service was even better.Highly recommended.

This was bought about 6 months ago and I just wanted to use it before I wrote a review.First I charged it totally, it seemed like it took a while, but after an over night it was fully charged. After about three weeks, I had a low tire so that was taken care of, the compressor is loud that is why the 4 star rating. Then I aired up tires on a garden wagon, again no problems. The it was put in the trunk of my car. Last month I checked it and the battery gauge had dropped one bar, that is one bar out of four. Just a few minutes ago my neighbor came over needing his car jumped. The gauge still at three of four. The neighbor’s car started immediately no problem, the jumper cables were just the right length. Any way I will be giving some of these for Christmas.Other than the loud compressor, I am very pleased with this emergency tool.
