I'm planning to buy a ACDC pump, the one which automatically switches to dc when electricity is shut off, would it be better to buy a ACDC air pump? or just buy a UPS and connect a powerhead to it? The ACDC pump is almost the same price as the UPS.
Also how long would a 600KVA UPS be able to power a 25 watt powerhead?
