Portable Air Compressor - Vastar Mini Air Pump Tyre Inflator 100PSI / 2000mAh Rechargeable Lithium Battery with Digital LCD LED Light, Air Pressure Detection and Automatic for Car Bicycle Ball Tires

I got a bike recently, and had trouble inflating the tires with a standard truck-tire inflation chuck. Is it any wonder? Those things are turned up to around 150psi! This, however, worked perfectly. You can set it to any specific setting via the 'custom' setting, then just relax while its airing up the tires. For my bike, this was 43psi, and since it has relatively small tires, this device took care of it in under a minute per tire. I'm very happy to keep this with my bike kit. Its definitely much easier to use, especially out and about, than normal bike pumps.

A total waste of money. The device is very loud, takes way too long to inflate a tire even a few psi, it overheats easily, and it takes long to charge. I have two other portable devices, and those are much better. I bought this one thinking the small size would make it convenient to keep in my car, but after seeing how useless this device was, I realized I made a mistake buying it. Anyone that gave this device good reviews obviously haven’t tried other portable air compressor devices, most which work much better then this. Don’t waste your money.

I bought this to keep my bike pressure within the ideal margins. I've used it no more than 20 times. While it worked, it was rather noisy (and also slow to inflate the tires, by I thought that was on purpose not to easily blow away the tires), but it did its job. Yesterday, while inflating one of the tires, the device made a sudden jerk and then started to emit a super-acute sound (something is wrong), veeeeery noisy, and doesn't pump air anymore. Gone. I guess I'll have to deal with the warranty, but the thing simply broke down.

This pump is great! Once you figure out how to use it, it is super useful. Pumps bikes no problem. It can even pump a full-sized car tire! Other bikers on my trip loved this thing!

Everyone where I’m at has to have a bike to get around and having a cordless automatic pump for my shop makes maintenance much more simple.

It filled a car tire once however after recharging wouldn't pump air at all. The replacement pump is working perfectly and I appreciate Vastar's customer service contacting me and offering a replacement.
