This is a great little pump. I like that it is battery powered and rechargeable. It does come with a lot of attachments to pump up all kinds of things from tires to kids beach floats. The drawbacks are big though. The cable that attaches to the top is extremely short. A longer cable would make inflating tires a lot easier. Also the screen is unreadable in the sun. This is huge. The screen is bright and clear at night and indoors but as soon as you step out into the sun, you can't see read the info panel. All of the numbers become 8s. An LCD readout or a backlit type of panel would be better but in the sun it isn't going to be easy.

I've gone through a few portable inflating devices and the common denominators with all of them: cheap, flimsy, and unreliable. This portable tire inflator well designed, versatile, and reliable.WHAT YOU GETThe tire inflator unit measures at 6 1/2" x 2 3/4" x 2" and weights about 1 1/2 lbs.. Also included are a 14" air hose, 24" USB to USB-C charging cable, cigarette lighter charger (~10 feet), 4 adaptors (2 sizes of air nozzles, ball pump needle, and Presta valve), instruction manual, and a nylon drawstring storage bag.PERFORMANCEThis is a solid all-in-one inflation device presented in a smartly-designed and easy-to-use package. The power block incorporates a simple interface and a bold display. Simply screw in the air hose to the top of the power block, turn the device on, choose what you are inflating, set the psi cap, and click the power button again to start the inflation process. There are several features incorporated into the power block. All input receptors are located at the top of the power block: Air hose receptor, USB-C port, USB port, and DC-supplied power port. There is also a small LED light at the top. The power block interface is simple with 5 clearly marked rubberized buttons: on/off, flashlight, inflating option, and buttons for increasing and decreasing desired psi levels. The LED display measures at 2" x 1 1/2" and displays the inflation type setting at the top, current psi level (largest display), set psi limit, power block battery level and, when turned on, a flashlight indicator. The device powers off when inactive after about a minute.There are 5 inflating modes available: Car, motorcycle, bicycle, ball and free-mode. With the exception of free-mode, the other 4 modes have default psi pre-sets (car-36, motorcycle-32, bicycle-45, and ball-9). Regardless of what the default is, you can push increase/decrease buttons to set the cap you want from 3.0 - 150. The device adjusts the psi from 3.0 to 100 in .5 increments, and 1.0 increments from 100 to 150. The psi setting is looped and there is no hard stop on the top or bottom end, when you try to go lower than 3.0, it goes to 150 ... if you go over 150, it goes to 3.0. Holding the up/down button will rapidly increase/decrease the setting. The inflation rate is modest, but consistent. The device does generate some noise, but it isn't too loud.The flashlight button cycles through multiple options when press: on, slow blink, and rapid blink. It can take from 4 to 6 hours to fully charge the device (depending on the charging source). I have yet to determine how long a charge lasts.This is a great emergency tool to inflate just about anything and all components are easily stored in a convenient pouch. The convenience, ease of use and versatility make it a must-have handy device in a vehicle.

Great product! We carry this with us in our car, our RV and our motorcycle bag! It's there if we need it! Good strong battery and surprisingly quick inflation up to 150 psi. The preset modes are helpful and prevent overinflating. Also, if the battery loses its charge for any reason, it comes with a 12v charger as a backup. On a full charge, you can also use it as a battery backup to charge your other devices. This product gives me an added comfort level the further away from home we get and I always make sure to have it on us!

This thing is *wonderful*. I was having some trouble with my tires constantly setting off the "low pressure" on my car (have since been fixed), and it was so great having this little guy already in my car, ready to get those tires back up to pressure. It IS very loud, but it also shuts itself off when it reaches the pressure you've set, so I just walked away from it (it does say in the manual not to leave unattended while in use). Having a power bank backup is also great, and if for any reason the inflator has lost its charge, you can use it while it is recharging with the insanely long cord that plugs into a cigarette lighter port (although it claims in the manual it can't be done). It comes with several different needle attachments, so I can reinflate my daughter's basketball, get my bike tires back to full pressure, inflate the king-size air mattress for camp, etc. It even has an emergency flashlight, as well as a red light that flashes Morse code for SOS. This is perfect for keeping in your car, taking on your bike, camping...so many uses.About the only think I don't like that much is the storage. It's a thin bag. With as many bells and whistles as this has, I could only wish that it had an actual case for storage, so it, and all the attachments, are better protected.I also don't like the product information given here. It claims to be both 20000mAh and 6000mAh; it appears to actually be 6000mAh.Do be aware that the hose and attachments can get hot (the closer you get to a recommended 10-minute max usage time).Overall, though, this is a great little unit. It has saved me so much time (not having to drive around to get to an air machine), and I'm a big fan of having backup/repair items I can just toss in the glove box or trunk. Recommended.

Works well, small enough to keep in a medium-sized glove box, very handy to have on the road during emergencies!
