Mini Air Compressor 250 PSI / DC 12 Volts

Looks sturdy and with accessories, i tested it but it cant inflate my vans tire even i let it stay it for 5mins. Tire is still the same inflation so what i did i just get my manual pump to inflate the tire not more than 5mins it did the job...final verdict this tire pump is only good for bicycle or ball not for car tires...

I was looking for a manual foot pump for my daughters bike and topping up my car tires in emergency. This being electric (and me being lazy) and claiming to be a 250 PSI seemed like a good option for almost the same cost of a good manual pump. I was proven wrong the minute I opened up the box. This barely blew up a basket ball and failed miserably when I tried it on my car.In the manual it warns not to run it continuously for more than 15 mins (7 mins if running at 75+ psi). And to wait for 10 mins before starting again.Pros: - Ok for small bikes and medium size inflatable pool toys - Light weight - Portable - Price (!!)Cons: - Light weight, shakes very badly when running. It feels you need to screw it to the ground. - Power supply. Fails miserably on car tires, not sure why any one would want a cigarette lighter plug for using it on a kid bike. - Low quality material, doesn't seem like it would last long even with infrequent use. Very low quality wire used - this would be the weakest link in the chain. - Short run time. 7/15 mins seems long, but at the rate this works renders it useless for anything serious.Apart from this, pressure gauge was not accurate - it might be broken on my unit as it didn't moved at all even when trying it on my car tire. Well this is going back where it came from - my first return in years on Amazon.
