CYCPLUSAL7 Tire Inflator Portable Air Compressor for Trucks & Pickups – 4X Faster High-Powered Tire Inflator, Portable Design for Heavy-duty Vehicle & Inflatables, Dual-Use Type

I love this thing! I was very skeptical about it, as I've had some very weak and unimpressive similar products before. I'm very happy with this air pump. It is small, but still loud, not as loud as my dual tank air compressor. But this thing is fast, so you don't have to listen to it for too long. When I say fast, I mean it, only takes a few seconds to fill something up.It is easy to use, press and hold the power button, adjust the dial to how much PSI you want, it adjusts in 0.5 increments. Then press the power button to turn it on. While running, it shows you how much pressure is in the thing you are inflating, when it gets close to full it does slow down a little, then stops when it hits the desired PSI. This is a fantastic safety feature to prevent over inflating as long as you check how much air should be in something first.There is an LED light on it which is nice if you are having to use it in the dark, or for emergency light.The handle pulls up which reveals the usb-c charging port location.It comes with the hose permanently attached and stored inside a little covered are on one end, this is where the usb-c cable and the 4 attachments are located, the attachments can attach to the cover of the compartment. I just left the usb-c cable in it's little pouch inside the compartment. An external DC power cord is not included, which is fine.The charge will last depending on what you are filling and how often and how much PSI things need.I've used this on one tire of our SUV, and 2 tires on 4 bikes and it's still got power left.This thing is worth every penny and very glad I got it.

UPDATE: I went to the CYCPLUS web site and submitted a support ticket. I got a quick response and two suggestions to try: sitting the target PSI much higher than the current tire pressure and to use the bike setting. That worked once then went back to the same sputter and stop problem. After I reported the results, they sent out a replacement AL7 which arrived quickly. The new AL7 performed exactly as advertised, even handling the large tires on my F350. I hope I can depend on it because this is the smallest, lightest, battery powered tire inflator I've found that will do the tires on the F350, and with more than enough battery to add 5 PSI to all four tires.Like too many of these small portable tire inflators, the controls are not lit and the onboard light does not shine on them. The AL7 power and light buttons are flush with the case and the same dark color: a terrible combination for trying to work the AL7 in bad lighting. I used a silver sharpie to color the power button and that helps.The display is readable in bright sunlight.The air hose is not short, but it is not long enough for me to set the AL7 on the ground if the tire valve is high up on my RAV4 tires. Not sure I would anyway unless I had something clean to set the pump on so no dirt/dust/water got sucked it.I'll try to remember to update this review in a few months when I know if the batteries hold their charge.Original review:Maybe I have a rare defective unit, but my AL7 will not pump air when connected to a tire on my RAV4.The RAV4 tire is at 33 psi and I want it at 36. The AL7 shows the 33 and the set pressure to be 36. I press the button to inflate, the AL7 sputters twice, then stops. Battery is fully charged.If not connected to a tire, the pump runs. It seems mine cannot handle back pressure.I'm trying to get a replacement AL7. If I do, I will update this review.

This "CYCPLUS AL7" battery powered portable air compressor is one of those things I never realized that I needed, until I got one. It is quite surprising how useful it is for inflating tires, inner tubes, air-bed mattresses, etc. and I use it more often than I thought I would. It is so convenient to carry to the place where it is needed. The built-in battery works longer and pumps more air than expected. It will also pump tires to to a surprising level of air pressure. It is small enough to carry with me, and recharges easily using any wall-wart charger. The built-in LED screen and simple controls allow me to set it for the need at hand. I quite recommend it.

The noise level is about average for this type of compressor.. It is smaller than what I expected (not a bad thing).. I personally do not like the screw on type of ends, as it always loses some air pressure trying to take them off, especially with bicycle tires, so the 90 degree clamp on piece was nice to have. But my one complaint with it is, it is all plastic.. Because of this, when I went to put it on, it started to cross thread when I went to attach it.. I had to be very careful when putting it on.. I am just leaving it attached for this reason.I like that the hose is not some 1 foot, or 10 inch hose like what comes on a lot of compressors these days.. My opinion, no compressor should come with a hose of at least 18 inches.. Longer is better.. If you do not have it that long, then when you attach it to the car tire, it hangs and pulls on the valve stem hanging off of it if the valve is not at the bottom.. So this one with a longer hose is a good thing..I found it to be decently priced for the type of compressor that it is, and its battery capacity and air flow.. No complaints there.The light is fairly bright, so that works good for basic use..The plug to charge it is hidden under the handle.. The problem is, when you carry it, it opens up the USB and charging ports to dirt.. No dust cover on them.. So if you accidentally drop it, it is too easy to get dirt into the ports.. This could have been done better.Overall, most things are just minor complaints.. No major things to complaint about.. If asked if I would recommend it, so far, that would be yes.. But lets wait to see how it holds up over time.
