Does anyone have one of these cordless battery operated air inflators? Is it any good? The X8 is $60 at Amazon the S200 is $40 at Costco. It inflates faster than my corded 12v pump and has auto shut off when it hits the target psi. Thinking of getting some for Christmas presents. https://www.amazon.com/Fanttik-Inflator-Compressor-Inflation-Motorcycles-Yellow/dp/B09YD2D96V
I charged it up to 100% and then used it to fill up the following on some friends' cars:
4 215/60R16 - ranging from 26-30 pounds each and inflated to 36
4 235/70R16 - ranging from 26-28 pounds each and inflated to 33
This brought the battery percentage down to about 50%.
Automatically shuts off when the target PSI is reached
Time saver compared to inflating, shutting off, and checking with gauge repeatedly
Accuracy
Checked end result using a good gauge and it was within .5 PSI
Ease of use
Nice being able to skip the extra steps dealing with the cord going into the accessory outlet and using a tire gauge
Performance
It would add about 1 PSI per 15 seconds when fully charged (about what my dc air pump performed at)
The box says it "Supports up to 27 Tire Inflations per Charge (28-33 PSI)". It doesn't say what size tire that is based on so I am not sure if my results were necessarily good or bad but I like this thing. The ease of use will have me checking inflation more often and I will be topping off 2 to 3 PSI at a time so my test is worst case for me.
I would think this inflator would be especially handy for those who are not likely to keep their tires inflated because they don't know how to do it or don't have a pump and gauge handy.
I also tried it on a gravel bike using the Presta valve adapter it came with and it worked fast to get it to 50 PSI.
It also works as a power bank and has a flashlight and hazard light.
