thank you i like it

This is an adequate emergency tool to keep in your vehicle for tire inflation and other compressor needs. It would not be a professional use type of compressor. Its biggest issue is the very poor instruction manual. For example, there are several involved maneuvers you have to do to set the target pressure before use. The manual describes this as “After selecting the unit, please short pressing Power/Setting button to set up pressure data.”. Totally inadequate explanation. The manual has many similar minor English and clarity errors. The air hose is only 6 inches long, so you will usually have to hold the unit, rather than setting it on the ground while it is inflating. I found in inflating four tires, I had some trouble screwing the air hose on to one of my valves, but I did get it on. The inflation was reasonable for this type of unit. It took just over 2 minutes to go from 27 PSI to 33 PSI. The battery level went down by one of four bars after about 12 minutes of use. It has a nice bright and clear display of the current tire pressure when you screw on the hose and then turn on the unit which agreed with my car sensor and a manual pressure gauge. Among the useful features is that when the target pressure is set, you can pull the trigger, release it and the compressor will stay on until the target pressure is reached. I would suggest setting the target pressure very slightly higher than recommended, as the compressor stops exactly at the target and a bit of pressure is lost when disconnecting it. For example, I set the pressure to 33 PSI and when completed, all 4 of my tires read 32 PSI on the car sensor. It would work correctly when set to 32.5. One other quibble is that the battery pushes on to the compressor, but there is no click on the attachment or release button. They just pull apart. But I did not have any problem with the compressor and battery separating while in use. It comes with a nice case, wall plug and a cigarette lighter plug for charging. It also includes an air hose attachment for bicycle tires (Schrader not Presta). There is a compartment in the battery case that includes a pin for ball inflation and another for air bed inflation. An LED light is built into the battery base (it would have been more usable in the nose) and a very useful USB charging port in the battery. A good start, but could use more work, especially on the user guide.

I like that it can be used on battery power so can be completely wireless, can be charged with the car's lighter, or with an AC plug and has a digital display. I like the flashlight that's built into the battery compartment. The instructions, such as they are, say not to run it continuously for more than 15 minutes which isn't a problem. Then it has to cool for half an hour. It has lots of adapter nozzles (for bikes, etc.) I am annoyced that the tube from the pump to the tire is only 6 inches long, so if your tire's nozzle is NOT near the ground, you have to hold the pump up while inflating. When I was doing this, the battery fell down. My previous, plug-into-the-car compressor is less troublesome. And it automatically stops when it reaches the pre-set maximum pressure. It's easy to re-set the max pressure, but you have to do that. Like most battery-powered things, it's best practice to recharge often and remove the battery if it will not be used for long periods.

This Carywon Portable Air Compressor is a great thing to have in a pinch.The battery is a fast charge, only took about an hour for full charge. It lasts long too as long as you’re not using it every day. I like all the different tips it includes. Makes it easy to go from a raft to a soccer ball. There’s a fun compartment where they’re all stored too.I was also really happy that it has a carrying case! This makes it easy to keep everything together instead of having to remember where I put them. I will say I was confused on how to use it at first. It did not do a great job on my tires either. It took way too long. In a pinch and I needed it I would use it for that but if I could just drive to the local gas station and get air for my tires I’d do that instead.Overall, I liked it. It has multiple uses. I would recommend it because of that for sure. Who wants to take time blowing up pool inflatables with their mouth? I don’t. This made that easy along with other things.
