We loved the Coleman Quick Pump we had for many years, but it finally gave up the ghost and we ordered the newest version of it.  We charged it overnight before the first use as recommended, but the pump was weak from the start, barely blowing up one double air mattress.  It only worked a couple of times, then would not take a charge at all, no matter what we tried.  We did not need it often, so by the time we realized it was dead, we were out of warranty.  A note to Coleman was answered promptly, but only offered us 25% off any product on their website, none of which was a rechargeable pump.  Maybe we just got a bad one, but I can't recommend this pump.  Now I have to remove the battery and find someplace to recycle it, one last indignity.
