PowerBank 2 Power Conditioner

I plugged my subwoofer into this and the hum disappeared—the power conditioning really cleans up the audio. Works perfectly for a simple setup like mine.

Plugged my subwoofer into this and the hum I'd been hearing for months is just gone. The surge protection gives me peace of mind during storms too, since my old strip was pretty basic.

Bought this to protect my video projector and it's been solid so far, no hum or flicker during storms. Only gripe is the outlets are spaced a bit tight for two bulky adapters at once.
