Tire Inflator Portable Air Compressor, 150PSI Cordless Air Pump for Car Tires, 3X Faster Air inflator Tire Pump with Digital Pressure Gauge and Emergency LED Light for Motorcycle Bike Ball Car

Bought this specifically to use on my Harley Davidson Ultra Limited (2017). Everyone knows the hassle of trying to check and inflate the rear tire on a bagger. It’s difficult to reach up between the saddlebag and tire to get something on the valve stem. This little compressor will allow you to check and inflate to precision. You set the desired PSI into the inflator and hit the start and within a moment — your tire pressure is exactly what you want it to be. The unit will automatically shut off once the desired pressure is reached. Comes with a nice bag with drawstring type closure to keep the unit in and doesn’t take up much space at all in your tourpack. Comes with USB charging cord and extra accessories if you need to air up basketballs or an air mattress. The only downside I see is the battery will drain quick once you start the compressor. I added a total of 8 pounds of air and it took my battery life down a bar. I would assume if you needed to air up a completely flat tire, the battery would be iffy to reach 40 PSI — even though it advertises 140 or 150 PSI. Overall, definitely worth it. I just keep an extra Adapter on my bike in case I need to charge it more. It also has a flashlight that could come in handy if you’re ever stuck on a dark road or place.

Works great! I use it to make sure all of the tires on my vehicles and trailers have the correct air pressure. Decent battery - enough to adjust many tires on one charge. Nice size to store easily in storage compartment or glove box of vehicle

I moved to NJ where apparently they charge for air and I didn’t want to have to pay for it every time I needed to blow up my tires. I am from a state that air legally has to be free so it really threw me off and I immediately looked for my on way to blow up my tires myself. This device works but it does lose power fast. It uses a usb c which is convenient and it does automatically fill your tire to the correct pressure and then stop itself when it is done. It is nice that you do not have to turn it off. I set it to the pressure I need, set it up, and then sit there on my phone while I watch it just in case something goes wrong. I have been able to fill up three tires completely an partially filled up my fourth tire and a full charge so it depends on how low your tires are.

Perfect and compact. No worries while out and about with a low tire pressure anymore.

This is a great pump! It's the second small pump I've bought on Prime, and the first was a waste of money. But this one was worth every penny! Love having the semi rigid case for it too, which protects it very well. I keep it in my motorcycle's small soft tail bag at all times for peace of mind (I have an uncanny knack for finding nails with the rear tire). I don't pump my tires at a convenience store anymore, because these chargeable pumps really need to be used every once in a while to prolong the battery life anyway, and it's just a lot less hassle when you don't have others waiting for you to finish. I can pump up all the tires on the car AND the motorcycle an average 6 psi per tire and it will still have 75% charge, and it actually pumps them up faster than the pump at the convenience store! CRAZY! And I don't have to stand there crouched over keeping the stupid hose nozzle pressed tight on the air tire valve the whole time either. I'm getting old - my body doesn't do crouch so great these days. The fast-release clamp-on style tip on this is so much better. Takes a long time to charge but what else would you expect? It doesn't have any fast charge system because there's too many different systems. And it's a 10k battery so, yeah. That takes a while. I got the silver one cuz it's cheaper. Why is it cheaper? I don't care what color it is - it spends its life in the case anyway. And, I like cheaper. Lol Really one of the best buys I've made on Amazon!

Five stars, no hesitation. I bought this portable tire inflator specifically for my e-bike, and it has turned out to be one of those purchases that immediately earns a permanent spot in my gear. Compact, fast, and incredibly convenient — it does exactly what I need it to do. First off, the cordless design is a game changer. Not having to mess with cords, outlets, or my vehicle makes this insanely easy to use. I just grab it, turn it on, and inflate. For an e-bike, that convenience matters a lot, especially if you’re topping off tires at home or want something reliable to carry with you. The digital pressure gauge is accurate and easy to read, which I really appreciate. I can set the PSI I want and let it do its thing without constantly stopping to check pressure. It shuts off automatically once it hits the target, which takes all the guesswork out of it. That’s huge when you don’t want to overinflate bike tires. Speed-wise, this thing is impressive. It’s noticeably faster than I expected, especially for a portable unit. Topping off my e-bike tires takes no time at all, and it doesn’t feel weak or underpowered. The “3X faster” claim actually feels legit based on how quickly it gets the job done. The size and portability are perfect. It’s small enough to store easily in a bag, trunk, or bike storage area without taking up much space, but it still feels solid and well built. It doesn’t feel like a cheap plastic gadget that’s going to crack the first time you use it. I also love the built-in LED light. It’s one of those features you don’t think you’ll use much… until you do. If you’re inflating a tire in low light or at night, it’s incredibly helpful and adds a nice safety touch. Another bonus is the versatility. While I bought it for my e-bike, it works just as well for motorcycle tires, car tires, and even things like balls. It’s nice knowing I’ve got one tool that covers multiple needs instead of separate pumps for everything. Bottom line: five stars because this inflator is easy to use, fast, accurate, portable, and perfect for an e-bike. It gives me peace of mind knowing I can quickly handle tire pressure wherever I am. If you ride an e-bike or just want a reliable cordless inflator, this is absolutely worth having.

Works great for my e bike ) easy to use

I wish it's factory default was in PSI instead of BAR and having to change that every time I go to inflate a tire is the only reason this machine is missing one star from its review. It will inflate a full size truck tire in bicycle mode takes longer but it works In car mode you have to change it from bar to PSI or do the conversion thing on Google which is what I was doing for the first month before I figured it out. Yes the auto shut off works and it is reliable. Very easy to use set your bar or PSI and it turns off when it's done. As far as portability goes it's not going to fit in your pocket but it's great for the center console or your glove box. As far as speed is concerned it's not the fastest air compressor but it's not slow either... I'd say 15 minutes to go from no PSI to 50. Noise level it's an air compressor they're not quiet now compared to my DeWalt air compressor this thing whispers it's also very tiny in comparison I could paint a car with my DeWalt air compressor You're not going to do that with this thing. Now for the con it will overheat and shut itself off so keep it in the shade if your in a hurry. If it's cold out this thing's perfection but if it's a hot summer day it might overheat I have found simply leaning a hat over it helps considerably during the summer months in Florida Oh as an afterthought I have inflated bicycle tires and footballs for these it's very fast just make sure not to over inflate stuff cause it's strong enough

The AsperX AX70 Portable Tire Inflator is a very convenient tool to keep in the car. It’s compact, easy to use, and powerful enough to quickly inflate car tires, bike tires, and even sports balls. I really like the digital pressure gauge, which lets you set the desired PSI and automatically stops when the tire reaches the correct pressure. The built-in battery is also very useful since it’s cordless and portable. It’s great for emergencies or regular tire maintenance, and the size makes it easy to store in the car. Overall, a reliable and practical inflator that every driver should consider keeping in their vehicle.

Equipamento muito robusto, mesmo sendo a carcaça toda de plástico, percebe-se que é de uma qualidade superior a maioria. Extremamente eficiente, faz barulho como todos os concorrentes, porém muito mais eficiente no que se propõe. Para calibrar os pneus de 29 - 35 demora menos de 15 segundos.

I’ll give it 5 stars but I haven’t had a chance to use it yet I bought the 160 psi model and I’ve been happy with it

Très utile

I bought mine on sale for 40$ CAD. They go on sale for a week it seems every month. It does the trick for my car, but dont expect it to be as performant as a 100$ model. Ive used it 3 times now and it has inflated my tires each time. It does have issues sometimes with reading the pressure as it will jump up and down by 2psi as you are filling it up, but will still get to your desired pressure. It got my tires from 30 to 40 psi without issues. Make sure you keep your battery charged as after topping up your tires twice, the battery gets pretty low. The additional light on the compressor is a VERY nice touch in the dark. Would recommend for the price when on sale.
