CYCPLUS Bike Tire Pump, Portable Electric Tire Inflator with 150 PSI and Auto-Stop Wireless Rechargeable Air Compressor with LED Light, Fast and Easy Inflate The Bike Motorcycle Car Balls

This product works as described. It fills car tires relatively quickly and both the display and the settings are easy to read. The tire pressure adjustment setting are also very easy to use. In addition, the nozzle easily locks on to the tire valve stem and does not appear to leak. This makes it easier to use than a gas station nozzle where the user must hold the air pressure nozzle on to the valve stem at just the correct angle. I literally locked the nozzle on to the valve stem, pressed start, set the product down and waited for it to automatically turn off when the desired air pressure was reached.The product did not come with a AC adapter for the USB charging cord. The USB cord, however, is a standard size. It appears that it would easily fit into an old cell phone AC adapter. One would have to contact the seller or manufacturer to verify whether it is wise or not to do this.The only downside is that the charge did not last a very long time, at least on the first usage, even when fully charged. It was sufficient enough however to top off 3 out of 4 very low car tires. The low cost of the product, however, makes up for this minor inconvenience.

I have used CYCPLUS products (Bike Computer). I was extremely happy with their products and customer support. I would highly recommend this product. Coming to this Air PumpPositives1. It is looks so tiny. It is much smaller than what I expected.2. It does its job in not time. It shutdown automatically.3. Display is awesome. Light is a added plus.4. Quick charge. It hold charge for long time.5. Awesome customer support.Area of improvement1. They have several versions. There is no clear way to find the difference. Some versions have USB port, mine came with the age old micro USB. Love to see USB C in future. The other version comes with a bike mount but mine didn't come with that. It came just with a carry on bag. Some versions also comes with 12v lighter plug. Mine came just with a USB to micro USB cable. Check all 4 versions and buy the one you like.2. Air tube storage could be improved. Also Air tube length can be increased. It is hard to hold the pump in hand for long time. If the tube length more then we can place it in the floor. But I didn't face any issue when filling air on my daughter's bike. Also, it will be good if the air tube value is rotatable (i.e. after connecting).I highly recommend this product to anyone who need a reliable compact air pump.

Okay this thing is pretty good however I have two complaints. The first is that this unit comes with a very short USB charging cable. It also comes with a very short inflator tube that connects to your tire. So that is the only two downsides to this particular unit.However this air inflator is very compact in comparison to another air inflator unit that is also automated like this one. It will easily fit into a small pocket in a backpack. You can't really beat what you're getting with this particular inflator.It is a mini air compressor.However I bought a longer extension for the inflator tube that works a lot better than the short inflator tube that it came with. I also bought a longer USB charging cable.Depending on what air pressure you desire for your tires it may take two to four minutes to inflate. The pumping power is about the same as other automated air inflators so I didn't really expect that for the size. This air inflator is easy to understand and operate and comes with a few connectors for presta Schrader etc. It even came with a LED built into the unit. I did not expect that so all together I give this four stars. All in all I will see how many years this thing lasts. as I bought it for my bicycle, I really don't like using any type of manual pump however I have a manual pump as backup in case this thing runs out of charge. I had another one for about 5 years and decided to buy this.

I use this to check and fill my bike tires to about 85lbs. about 3 times a week. I like to keep my tires firm, because I to top off my tires often, I don't use it for long periods of time and it doesn't take a lot of charge. I have only charged it once after over a month. I don't use it for my car, because it does get hot if you use it for a long period of time so I can only tell you about bike tires. It's lightweight, works quickly, stops at the desired pressure the valve pops off with ease so there isn't air coming out of the tire while trying to remove it, overall is very easy to use. In addition it fits easily into my backpack. My one complaint would be that it is loud. But the ease of use makes it worth the noise.

This pump simply doesn't work. I opened it, charged it...then tried to pump a single bike tire to 80PSI. too much air was leaking around the Presta adapter. attempted to use the rubber gasket that came with the pump iat it helped a bit, but would only inflate the tire to around 42PSI before the battery quickly died.Charged the battery to full the next day... when I turned it on...it only showed 1 bar...and again... it could not inflate the bike tire.For those of you that think, "Hey, maybe he just got a lemon." Okay... perhaps... but if you order reviews by date you will see TONS of one star reviews for recent purchase... all with the same comments. I would also point out that even if you are lucky enough to get one that actually seems to work...this is the A3 (black) model. For a few bucks more, the A2 (white) model comes with a USB charging port for your phone, and a mount for your bike...this one has neither.I was not impressed with the build quality of this product and do not have the confidence that a replacement product would work much better for any prolonged period of time. My personal recommendation is to stay away from this product and others by this company. Mine is going back to Amazon.
