false advertising

This compressor will probably work fine for standard car and bicycle tires. In fact, It seems it would work for most higher pressure tires like those on touring/racing bikes. However, if you buy this product because you saw the advertised 300 psi capacity and are one of the few who actually need it to perform above 180 psi, you will be disappointed. My own experience with the compressor involved using it to power a toy rocket that required air pressure to burst plastic discs to provide an impulse to propel the rocket. The compressor would level off at 180 psi and start smoking. The car engine was on and enough voltage was being supplied.
I think the 300 psi advertisement is considered a safe lie by the producers because most consumers won't require enough pressure to uncover the truth. Also, I don't think there are going to be many other compressors sold to work through the cigarette lighter that will achieve their advertised psi limit. 300 psi is a fairly bogus claim, however, considering that 180 is the actual limit. And the longevity of the compressor is suspect because after the initial 180 psi limit was discovered, it immediately started degrading on subsequent attempts.
