CARYWON Portable Air Compressor Mini Hand Held Tire Inflator Electric Auto Air Pump Built in LED Light and 1000mAh *3 Battery 150PSI for Car, Motorcycle,Bike, Bicycle and Other Inflatables

Light weight and handy.

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.

The CARYWOM portable air compressor is impressive. I was highly skeptical that this pump would be able to inflate anything other than basketballs, soccer balls, etc but I put it to the test.Pros:LightweightEasy to useIncludes several common adaptersComes with carrying caseInflates small tires without any issueEasy to rechargeCons:Larger tires will drain the battery fast (see below)Slow charge times (about 40 minutes)I inflated several items with this pump from basketballs, soccer balls, bike tires both kids and adults, stroller tires, snow blower tires and finally car tires. I will say I am very impressed at how well it handled all of these with ease especially from something so small.The inflator pump is easy to use. Turn it on, set the required PSI/kpa/bar/ and press the on button again to start inflating. Once it reaches the specified pressure it automatically shuts off. This is a great time saver as you don't have to sit and watch the inflator and stop it when it hits the pressure you want. It's all done automatically.There is a built in LED light for the screen that lights up and is very bright and help display the numbers. The inflator also comes with 4 different adapters and a carrying case. It includes the important needle adapter for soccer and basketballs and it all stores nicely on the backside of the inflator pump.So my only issue is that they state you can pump up a car tire from flat in 8 minutes. I have a vehicle sitting in storage that is rarely driven. I wanted to see how this pump worked in this situation so I took the unit off the charger after it was full and hooked it up to the tire. The tire read 15 psi and I wanted to inflate it to 35. I programmed it and set it. After about 10 minutes of running I could tell the pump was starting to get quieter so I checked the battery level and it was flashing on the last bar meaning it was going to die soon. The pressure was at 30. It eventually died at 32 psi and I had to recharge it which took about 40 minutes. Their test could have been an empty tire not mounted to a vehicle thus no load on the tire.Overall, I still think this is a great pump. I really like the portability of this and it works well.

This CARYWON Portable Air Compressor is not the best for car tires but it's excellent for bikes and sports equipment.This compressor is cordless and has a rechargeable battery. You can use it to fill bike tires and sports balls and air mattresses - all sorts of things - but it's not super powerful so it takes forever to fill up an automobile tire.In the box, you get the compressor, the battery that twists on and off the compressor, a twist on tube for filling tires up with air, a drawstring bag for storage, and a small user manual. On the back of the of the compressor is a small compartment that holds various tips for filling things other than tires.You charge the battery using a micro-USB charging cable (included.) There are LED indicator lights that show you the battery charge level. The instructions are a bit confusing but you can set the PSI you want and the compressor will fill until it reaches your pre-set amount. There is also an brightly lit display so you can see as it inflates.The battery is 1,000mAh and it's really not enough to inflate a completely flat tire but you can top a low tire off in a pinch, although it's not fast. If you want this primarily for automobile tires, I would suggest something more powerful (and more expensive, too) like this: https://www.amazon.com/BLACK-DECKER-BDINF20C-Cordless-Multi-Purpose/dp/B07L6Y4DXP/ I own this Black + Decker compressor and it's fantastic for keeping your car tires fully inflated.However, this CARYWON compressor is spectacular for bicycle tires, tires on lawn carts and dollies, as well as all sorts of inflatables like sports balls. It's compact so easy to carry with you in a backpack or bag. We have used it a number of times already.
