We have NRS big earl and badfish SUPs and 2 years ago invested $175 in Bravo high pressure electric pump. It has stopped working. I was told there was adaptor that you can buy to convert standard air compressor to allow for filling to high pressure. Any experience with this? I have k pump 220 to top off on river but often it is my wife filling sups so doing it by hand on regular basis is not going to fly. Any input on pumps/adaptors is much appreciated.
