Miserable spring this year...we finally broke 70 (21c) for the first time this year. Looking at Inverters cause I still need a way to discharge a pack. Some are labeled for a specific voltage...and some are advertised "Universal". Like this one https://www.ebay.com/itm/403703441620?_ ... %3A2563228
Is this a misleading ad? I should only get a 24v pure wave Inverter and not a modified wave or a square wave Inverter correct? Is there any reason to get 220v ac output? Living in the US all my appliances are 110 as far as I know.
