Hi there, Seeking some advise. I know that a K-Pump, Carlisle, or Kwik pump is best for topping off, but can anyone recommend a good electric pump that connects to your car battery - for the initial pump? (I was gonna type "the initial blow...", but that's another forum). I've researched a bit and found one on the NRS website under 100 bucks. Is that the best I can do to take the one year warranty and run? This will be for inflating a rolled up rafts or pontoons not too too frequently, maybe every other weekend-ish, much more often in the summer.
