I ride a motorcycle, so I bought this mainly because of its size. At first I was a little leery about what sort of performance Id get from something so small and cordless. Ive only used it twice so far, but both times it worked flawlessly. The second time was from a completely flat tire to full pressure. Obviously its not as fast as what youd get from a large compressor, but Id estimate it took about 3 or 4 minutes to get to 38psi with enough charge left to do a second. Size wise, its about as big as a small paperback book. Weight wise, about a can of soda. My only minor complaint is the knurling around the collar that screws onto the tires valve stem is smooth, not rough, so it makes it a little difficult to get a good grip on it while screwing it on or off. I would prefer either a larger collar, or deeper / rougher knurling.

This is a great product to have when you need to air up your tires and you are nowhere near an air station. It is small and convenient.

This device is great for my motorcycle. Very easy to attach it and ensure my tires are at the exact cold tire pressure they need to be before each ride. I did however use it on my pickup truck recently to bring one low tire up to its proper PSI, and I noticed the unit and the inflation hose got very hot. This never happens with the motorcycle, I assume because its not moving as much air to reach its PSI goal, but it was a little concerning on the truck. I probably would not rely on this device for a car or truck as a regular usage inflation device. But perfect for motorcycles and I would assume bicycles as well.

So, I just used this today for the first time - I needed to get 4 tires from 25psi to 35 psi. It took nearly the whole battery, but it did do it. Display very nice. Hose is a little short - if valve stem not at bottom of tire, one needs to hold on to the inflator so it doesnt just dangle by its hose - hose is only about 6 long. Stopped very nicely at the 35psi pressure I set. The hose does NOT clamp on, but has to SCREW on to the valve stem - and that was slightly difficult because the valve stem doesnt really clear the metal of the rim on my vehicle. (Hose has a turnable coupling on the tire end so one can screw it on to the valve stem.) Cant really speak to accuracy, but this device reads about the same as the little tire gauge I have. All in all, Im pretty satisfied, and this is a lot easier to use than firing up my big compressor in the garage.

Didnt know this kind of technology was out there, Im old as hell apparently. Anyway, its a great portable no hassle pump for your bike or motorcycle! Solid build.

Set the pressure and start and it will pressure UP your tires. Unfortunately it wont pressure down. Too much $for one that wont do both.

This seems to be more accurate when filling tires than going to a gas station with the big compressors. Its not super fast at inflating but simple and easy to use.

Bought this to fill up my motorcycle tires prior to going on rides and was easily able to pack it up and bring it with. Simple to use and durable.

This is awesome for anyone who wants to avoid tire shops for air checks and even in emergencies on road trips. Got it as a gift and they loved it! Managed to air up all 4 tires leaving the battery at about half way full.

This product initially gave me an error message “E07” but it was replaced and now works perfectly! Great customer service and follow up!
