I've been using small compressors that run off of auto cigar lighter sockets for 5 years with no problem. I have 2: one I bought in Taiwan and the other here at Wal-Mart (C&H is the brand, xx & Hausler?). The Wal-Mart one is a bit better in that it has an On-Off switch. For both, filling a bicycle tire from flat takes maybe the better part of a minute. In any case, the pressure rise is slow enough to stop where you want it. In that time I have used Continental tires exclusively (GP-3000 and 4000) and Continental or Bontrager tubes. I typically run the tires at 110 to 120 psi.
