TIREWELL Tire Inflator Portable Air Compressor, 12V 150PSI Air Pump for Car, SUV, Motorcycle, Bicycle, Tire Inflator with Gauge, Air Car Pump with Battery Clamp and 5M Hose, Twin Cylinder Air Pump

Added November 2022: Compressor is still working fine. It doesn't get a lot of use (a few times a year), but it works each time I need it. I got tired of the screw-on fittings so I've ordered a clip-on chuck (https://www.amazon.com/dp/B07MX882J8?psc=1&smid=A1ZZK63NUU4DVM&ref_=chk_typ_imgToDp) to add to the kit. [Original Review] My old tire inflator gave up the ghost and I needed a new one quickly. The reviews on the Tirewell were favorable so I gave it a chance. Amazon delivered it the next day and I put it to work airing up the tires on my girlfriend's minivan. I plugged into the 12vdc power port rather than use the supplied aligator clips on the battery. When I screwed the air line into the valve stem on the tire the pressure gauge read the current tire pressure. It's not a high precision gauge, but it's sufficient for the job at hand. I prefer the screw-on connection to the clip-on style of my old inflator. The screw-on connection is easier for me to put on and take off without swearing at the mechanism. Yes, a little air is lost in the process, but I always overfill and check/adjust (bleed off) pressure with a hand held tire gauge. I was pleased to hear it was not especially loud. My old unit was never this quiet. You could carry on a conversation while it's running if you had to. I had to air up all four tires. The total run time was less than 10 minutes so I didn't have to worry about the 10 minutes on, 10 minutes off duty cycle. The power cord was long enough to put the inflator next to two of the tires, for the other two I had to use the coiled extension air hose. It felt a little flimsy, but it got the job done. It's probably the right quality level for a lightly used consumer product. I liked that the carrying bag has a dedicated pouch for the air hose. I'm happy with the purchase having used it one time. I'll come back to update the review after I've used it a few more times and put a few miles on it.

(Update 12/27/18) Still working well months later... My son realized one of his SUV tires was low, borrowed this in November and it worked great for him to pump up the tire to get to a shop and have it fixed. (Original review) Bought this after a tire went soft in our RV last weekend, and we drove around for 1/2 hour looking for a large filling station where I could get the RV into and reach the tire to pump it up, to get home, after finding it apparently had a slow leak over our stay. So far, it's just what I hoped. I tested it by pumping up the low tire, which was at 60psi, and I needed 80psi. It is very slow, but I expected that for this type of pump. I pumped the tire to 70lbs first, let the pump cool as directed, then did 10 more to 80psi. Took two passes of about 7 minutes each. Pump is much quieter than I expected, and came with a really nice heavy nylon carrying case with a side pouch. The 12v cigarette lighter extension cord that I got to go with it fits in the case nicely. It also came with an adapter for attaching to the battery (which is what I used first time). Also a few little adapters for balls, etc. The yellow hose helped make it much easier to reach my rear tires. The included screw-on tip is a MUST for high pressure tires, as the clip on ones do not hold well at that high pressure and above, in my opinion. My compressor has the clip, and it's a PITA to use. I much prefer the screw-on tip so far. I specifically looked for one with this tip, for that reason. I'll try to update my review again after I've had this for a while, but so far, I'm very happy with it!

The product arrived quickly and as described. Upon first opening the box, it was easy to identify all the parts, and put together the parts I needed to fill up the tire on my truck. It's a 265/75R18 which I fill up to 44psi. I hooked it directly into the 12v accessory socket, and used the coil hose extension. It was easy to screw together, and screwed the other end onto the valve of the tire. I then turned the unit on, and it immediately jumped to 30psi. I had read the instruction booklet and troubleshooting guide prior to turning on the unit, to see if it needed a burn in period. I had read a previous user review that they had done that, so I was seeing if it was a requirement, as I know you usually want to give any new machine with pistons a break in period to seat the rings and what not. I didn't do that in this case, but I was concerned about the high pressure reading right off the bat (the tire was completely flat), so I checked hoses, fittings and connections to ensure there was no kinks, and that the valve stem was fully pushed in with the screwed on fitting. Everything was working correctly except for the gauge reading. The pump ran fairly quiet compared to most other pumps I've used in the past but it's not whisper quiet as I've read in other reviews. I loved the stability to it. It did not bounce our vibrate all over the place like typical pumps do, and the needle on the gauge was steady. It wasn't super fast at pumping up the tire, but definitely much quicker than a single piston pump. It took about 7 or 8 minutes to get it to about 34psi, before I turned it off because the hose coming off the pump was getting extremely hot. The pump however remained cool. I love the bag it came with. It made it easy to get everything put away quickly, organized, and easy to carry. I was in a hurry so I didn't finish pumping up the tire to 44psi, as I normally would have after it cooled off. I did however use the pump again the next day on my car tires. The 2 rear tired were about 5 pounds and 8 pounds short (34psi was the target). This time I used the hose directly off of the pump, and I was once again greated by the 30psi on the guage, once I turned it on. The tires pumped up in about 2 minutes or so each, and I double verified this with my own tire guage. So I can say at least that part of the guage is accurate once it gets past 30psi. If it was below 30psi that I needed however, I would have to turn off the unit, and check it with an external guage. So it appears the check valve is faulty on the guage, because it's measuring the output of the pump itself until that pressure is exceeded by the total volume of pressure past 30psi in the tire itself. Other than that, it's a seemingly good quality pump, and it'll get the job done. I haven't tried to fill a 100psi tire yet, or one larger the the one I have which is larger than the current industry standard for most truck tires, particularly those for this vehicle, which normally use between 185/60R15 & 215/75R15 compared to my 265/75R18. Another way to compare is the 185/60R15 has a diameter of 23.74in tall and is 7.28in wide VS my tire is 33.65in tall and 10.43in wide. So I have a lot more air to push into these tires, which is why I chose a dual pump air compressor over a single pump. I would probably recommend this pump to friends because overall, it is a decent/good pump, and versatile for many applications. They just need to use a better valve check on the guage. The only con is that once it gets to 30psi it struggles to pump the air at a steady rate. It slows way down, and the hose attached to the pump gets extremely hot. Ten minutes on, ten to fifteen minutes off, takes a long time to pump up a tire with high psi or large volume tires.

I got this to use on the road for my travel trailer/RV, and I was a little sceptical about how long it would take to inflate trailer tyres to 60psi requirement. This little unit did not disappoint; in fact, it's a lot better than I thought it would be. I plugged it into the 12v 20amp power outlet in the back of my Jeep and purposely didn’t start the Jeep. It was super easy to hook it up, and it got the one tyre from 45psi to a little over 60psi (I went slightly over to allow for loss upon disconnecting) in less than 5 minutes (I timed it). Considering that I was only using the cigarette lighter without the engine running, and the trailer is loaded to 3500 lbs, I reckon that is great! I would typically Jack the trailer up a little to make it easier on the compressor but I purposely didn’t do that either as I wanted to put this thing through its paces. The carry case it comes in is excellent with two separate sections, so nothing gets tangled up which is also helped by the coil hose which had ample length along with the power cord to easily pass under trailer (I used a piece of wire to reach under and grab it) to get to both tyres. I also checked the pressure with a brand new tyre gauge, and it was bang on the money with no loss of air from disconnect. I researched a lot of different compressors before getting this one, and I based my decision on whether or not it could inflate to desired psi in an acceptable time👍, the weight of the unit👍, ease of use and storage in the camper👍, affordability/value for money👍. This little unit passed with flying colours, and I’d highly recommend it to anyone who’s looking to spend any amount of time on the road travelling as I’m about to. kiwidogs.com

The first Tirewell that I owned worked well. After I'd had it for 4 years (used perhaps 12 times), it started making a terrible noise, and shaking like it was going to blow apart. I bought the same model this month, but the analog tire pressure dial on the new one showed 40 lbs. of pressure when my tire only had 28 pounds of pressure in it. It is useless to me with a dial that is so inaccurate. I tried it several times, and incorrect measurements happened every time.

Works great, maybe a little slow with big tires

I love this tire inflator!! I don’t need to drive much, so my truck sits in the driveway a lot, but, the tires do eventually do need air. This unit is the perfect solution for me. I also bought the convertor, so that I can plug it in to the wall outlet, but the supplied cords are plenty long enough to reach from either the battery or the outlet inside the cab. One thing to know, you really do need to use a seperate tire guage for accuracy & need to shut-off the unit manually, but other than that, filling my tires, was as simple as could be! If you choose to keep this in your vehicle for emergency use, pack a flashlight, because the air pressure guage is not lighted, but it will fit in the included roomy, travel bag. I even keep my convertor in the bag too. This unit is powerful & fast, for what I needed. Which was just adding about 4lbs. to each of the 4 tires. Start to finish, was about 90 seconds per tire. I really like the stability of the unit & the regular hose was quite long enough for my needs, but it is nice to have the yellow coiled hose, for those just in case moments. Overall, I am very pleased & would reccommend this unit to anyone.

Update #2: I contacted Tirewell and explained what happened, they informed me there is a 2yr warranty on it and sent me a new 1. It is really good to know they stand behind their products! I will update again in the future on the new 1. Update: I purchased in March 2019, used it a few times, and today while filling a tire it started making a horrible rattling sound coming from inside it. Obviously something has broken off inside. I would NOT reccomend! I'm torn on the number of stars to give it. I timed how long it takes to fill a standard 20" car tire that holds 35psi. I started with the tire having 15psi in it and it took 1:40 (1min 40sec) to get to 30. Not bad! Then it starts to struggle a bit and took another 2min 30sec to put 10 more lbs in. I put the tire to 40psi just because I was curious how long it would take since my Ram 1500 takes 40psi. 4 minutes to put 25lbs of air in the tire wasn't super impressive considering I have a cheap Slime brand backup compressor that plugs into the lighter and it took the same amount of time to fill the tire at a fraction of the cost. I really do like that you can plug this directly to the battery and it is really quiet. It comes with a zippered bag, a hose, needle attachments and the part that connects to the battery. I suggest buying a power outlet extension for it if you use it for a truck or full size suv so you can reach the back tires. Overall, it's not a bad compressor, is pretty quiet but doesn't seem much faster than some of the cheap ones.

Pompe reçue - voici une analyse détaillée. N'hésitez pas à la recommander comme pertinente :) - Le mode d'emploi précise qu'elle ne peut pas tourner plus de 10-15 minutes sans ensuite avoir un temps de refroidissement. C'est normal pour ce genre de système non professionnel. CECI DIT, LE CAPOT QUI SEMBLE être un refroidisseur est en fait un simple cache en plastic. Je l'ai donc démonté - il y a juste 8 vis -pour une meilleure aération (voir photo). C'est juste là un petit manque d'honnêteté commercial. -La machine est clairement de bonne facture générale -Sac de rangement : bien conçu et compacte. CECI DIT, un des deux bitoniau de la fermeture éclaire HS à l'arrivée ( ce n'est pas grave, il y en a deux) et je ne renverrai pas le produit pour ce détail. Quoiqu'il en soit le sac fait le job, il a deux poches et est bien pensé. - Le système est assez compact. Montage facile et efficace sur mes pneus de voiture. J'aime bien la poignée. - Bruit tout à fait raisonnable ! . Fil électrique bien long qui d'agir avec aisance. Fournit avec fusible de rechange. J'apprécie. - PRECISION DU MANO : correct par rapport à mes pneu regonflés dans une station il y a peu. Précision de lecture je dirais 0.1 bars. J'apprécie. - Vitesse de gonflage : Faible pour gonfler un pneu complètement mais parfait pour les correction. Possibilité de dégonfler un pneu en créant juste une petite fuite dans le connecteur (si jamais vous le gonflez trop). Attention, il faut couper la machine pour avoir une lecture correcte ( ce qui est normal et ne pose pas de problème ). - Flexible jaune pas utile pour moi mais il se range dans le sac. GLOBALEMENT : LE RAPPORT QUALITE/PRIX M'A L'AIR OK ET JE RECOMMANDE pour un usage d'appoint.

Ottimo compressore per il 4x4, per pneumatici tassellati e non.. Riporta i pneumatici a pressione stradale molto agevolmente (vedi video). Molto preciso il manometro incorportato. Bicilindrico, con pratico interruttore sul corpo motore e lungo cavo 12V per attaccarlo alla presa accendisigari e con riduttore a morsetti per attaccarlo direttamente ai poli della batteria. Se serve, in dotazione, c'è anche un tubo prolunga a spirale e accessori per gonfiare palloni e canotti. Il tutto in una robusta borsa a doppio scomparto. Consigliatissimo.

I recently bought this tyre inflator (TW2003) and must say that it's the best i've ever purchased and i highly recommend it. It's cost is well justified as it's well constructed, solid and sturdy. As for operation, it is superb in terms of inflation speed, quietness and lack of vibration. I couldn't believe how quickly a tyre pumped up to 32 psi was done and this little gem is well capable of 100 psi in quick time. The inflator comes with a lovely well made bag for easy and tidy storage in a car boot. I do not just recommend the product but also the company, Tirewell. When i received the inflator i had an issue and rather than return it to Amazon or contact them, i emailed Tirewell to see what they suggested. I received a response within a couple of hours and my issue was quickly resolved to my great satisfaction. I can honestly say that i have never received such excellent and rapid service from a company regarding a faulty product, so thank you Tirewell !!!
