Tire Inflator Portable Air Compressor, 150PSI Cordless Tire Pump with Rechargeable Li-ion Battery 9000mAh, Digital Electric Air Pump with Emergency LED Light for Car, Tires, Bicycle, Motorcycle, Balls

This right here is probably the best thing I've bought Amazon it works great. Charges up quickly, and the charge last for several days if not weeks depending on how much you have to air your tires up or air anything else up. Price was great too

I have been having issues with low air in my tires for a while. It gets hot here, then it cools down, then it gets hot again. There have been a few times where I have had to pull over into a gas station parking lot to fill up with air. Not anymore! I decided to give this portable tire inflator a try, and I am glad I did.Size wise, it's not too big. I like the fact that I can put it in my center console and not have to worry about it being there. It came with a few additional accessories like a needle and cone inflator tip, but what I really got it for was the tire pump ability. I tested it on a day when my tires were all a little low, and the nice thing about it is that you can set the tire pressure you want it to stop at. After firing this device up, it filled my tires to the pressure I was looking for. Later that afternoon, I checked my pressure using the car's built in sensors (I know, they're not as accurate, but still) and they were all at the pressure I selected. This is definitely a must have for people - if your tire is a bit low, no need to worry with this portable pump in the car!

I'm a long distance endurance motorcyclist and am always searching for products that make life lighter and easier when I'm on the road and this tire inflator fits the bill perfectly. My previous mini-tire inflator is about 10 years old, requires 12v power to run, is relatively heavy and is difficult to pack due to its odd shape so I started looking for something better.There are several necessities that one has to carry on an Around The World motorcycle trip and one of those is a tire repair kit including a tire inflator and this one with its light weight, thin physical design and wireless operation is great because it does not take up a lot of space, does not add a lot of weight and it does not draw power from the motorcycle battery which is important in remote locations. In fact, its large battery capacity was the primary draw to me in making this purchase. Most similar products have a 2000 capacity battery, some have 4,000 but very few have 6,000 like this product does. That's important in remote areas with little access to charging facilities where the need for something like this is critical.I tested the inflator and found it to be very powerful, quiet and filled my motorcycle tires from 0 to 42 psi reasonably fast and still had enough charge left to fill them each another time....maybe more. That's impressive.I would have given five stars but a couple things that could be be improved. The two things that I wish it did have but does not are 1.) power bank functionality and 2.) the ability to run while plugged into a charging source. Again, with a 6,000 capacity battery storage it shouldn't be an issue but it would be nice to have the option just the same.

I bought this to replace an older one that plugged into may car. This one is rechargeable and will work wether you have power or not. It would be great for bikers to carry with them or to take on your boat or camper. It has a light on the front that will also blink. You set the pressure you want it to go up to and the type of tire and hit start. Then it automatically fills to the set pressure and stops when it gets there. There are all different tips and a bag to hold it all. Definitely well made!

I read the user manual included with the pump upon arrival. I actually opened the little paper folded accordion and read all eight panels of information. Page 6 indicates one should charge the unit on a 5V/2A power source and the power indicator with flash. The first 2A power source I tried resulted in the screen looping on and off, with no battery animation. I assumed it wasn't charging and tried and different power supply to the same avail. The combination I found that worked for charging the device was a 1A power supply and a different USB-C cable than the one included with the device. With this combination the battery indicator indeed animates a charging sequence (the current battery level n/4 bars blinks)After finally solving the mystery that was charging the Samaraiuno Smart Pump, I proceeded to attempt to inflate a slightly under pressure car tire. I followed the instructions in the previously mentioned user manual and upon getting to Step 3 on page 6, the unit displays a friendly "Err" message and turns off. Step 3 was pressing the power button, selecting car mode, adjusting the psi, and pressing OK to start automatic inflation, except in my case the device just said "Err" and didn't inflate or pump.I tried more combinations than described in the manual like with the charging problem, like having the unit powered up before attaching the air hose to the schrader valve but once the air hose was clamped onto the schrader valve, and unit presumably detected pressure, the display would indicate "Err" and shut off.From this point I reached out to After-sale Service with the problem I was experiencing with the pump. I wrote two emails and neither was responded to, they were sent to shiliu-aftersales outlook address as indicated on page 7 of the user manual.To conclude, I was really disappointed with the Samaraiuno Smart Pump overall, mainly attributed to the device not working at all, the user manual being more than deceptive, and the customer service ignoring my emails. I urge anyone considering this pump for purchase not to do so, as it doesn't work and there is no customer service.
