I almost have my brewer tweeked on air, now I need to tweek the air in my truck tank. I have a 12volt air pump I've been using and it is better than nothing but could use more air in the heat. I have 2 air pumps, a MedCo45 and an eco 80 watt or 120 watt. I looked at inverters, but came across some generators on ebay. Here is 2 examples http://cgi.ebay.com/ws/eBayISAPI.dl...=CRX&its=S%2BI%2BSS&itu=ISS%2BUCI%2BSI&otn=12 and a cheaper version that would probably run my 2 pumps http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=330261851449&ssPageName=STRK:MEWA:IT&ih=014 any one use a generator? or inverter?
