Finally got to use the RAC600 the other day and was not disappointed. It inflated my flat tyre in about 2 and half minutes—very impressed with the results. It happened at night and had to use the built in light, very convenient and nice safety feature. This is a very advanced little compressor for the investment. You plug it into the cigar lighter socket and it flashes a default of 30 PSI, you can change that to whatever tyre pressure you need and then let do its job. No one should be without this small and portable safety device, I’m glad I have it and it now lives in the boot.
