Cordless Tire Inflator Portable Air Compressor Pump with Digital Display and LED Lights,Built-in Power Bank Perfect for Car Bicycle Air Mattresses Airboat Airbed Basketballs

Light weight and handy.

This is one of the best tools you could ever have in an emergency. I charged it up and I’m going to keep it in the car. It came with almost a full charge which was surprising. This has a built-in power bank that you can use with a USB cable. This also comes with five different tips. This is so easy to use and light weight. You can set it to whatever pressure you want and fill up a tire or a ball or whatever you need it filled up. Very high-quality material.

So much better Han paying $4 for aircat a gas station and having to use a separate pressure gauge.

I have a number of inflators and this Carywon is the most useless and tedious to operate. With one of my other inflators, I can inflate a truck tire in half the time and it is much easier to operate compared to this Carywon. It also does not inflate to the pressure you set it to, ex; I set it to 33 psi and it stopped inflating at 32 psi. It is also tricky to activate the pump since the power on/off button is also the pump on/off button. It also does not run very long as I could not inflate four truck tires from 29 to 33 psi before the battery needed recharging.A worrisome issue is that the hose gets hot. Almost too hot to touch. None of my other inflators ever get hot. After sitting for a short time after inflating tires, the case gets warm indicating that the motor is tranferring the heat to the case. If the motor is getting that hot, it probably will not last very long.I think there are much better inflators for less money.

I was very excited about this item because this could be used for car tires, bike tires, balls and anything I'd want inflated. It was also completely portable, without needing an outside power source.The control is a bit finicky, and I was willing to overlook that. Unfortunately, I don't think it's that accurate. However, the biggest issue is the short running time. I used it to inflate an inflatable sled. I tested at home to see how it'd inflate, which went okay. However, due to a lack of space, I had to deflate that sled. This pump didn't last long enough to inflate the sled while at a snowy area. I was able to finish inflating with another pump powered by the car's cigarette lighter but was disappointed this pump didn't hold enough charge to inflate the sled.I would not want to be stranded on the road with a subpar pump. I guess I can use it if there is no power source for my other pump out of desperation, but this wouldn't be reliable.The only thing I liked was incorporating all the adapters neatly into a compartment on the pump's side. Otherwise, I would not use this. Disappointing.

The CARYWON Portable Air Compressor Mini Hand Held Tire Inflator is a good starting point for this company with lots of potential. The lithium polymer powered battery helps reduce the overall size of the unit, but the weak 10000 mah ratings which doubles as a power bank provide limited long term use. I fully charged the unit and filled both of my tires from 20 psi to 36 psi and it took a good 8-10 minutes. The pump sounds fast but lags behind in efficiency and power of my other lithium power pump. The controls are fairly easy to use. There is a button for the battery capacity; two buttons to increase and decrease the psi; one button to switch between the different types of readings and finally a on/off button which also doubles as a start button. The bottom battery is detachable (twisted on) and can be used as a battery bank separately. I wished they stuck with traditional Lithium Ion batteries as oppose to a polymer type since 18650 are plentiful. The unit has the size and shape of a large mag light with a handy storage area built in for the the various attachments. The hose is relatively short and the screw in interface is very narrow, making it difficult to tighten / loosen fully. The inflator comes with a felt bag which slips over the unit and has enough space for the hose attachement, but provides not protection. Overall, its a good unit with a backlight screen. Hopefully the next iteration will feature a larger motor, longer hose and larger battery pack.
