When a storm kills the main feed, an automatic transfer switch decides whether your lights stay on or you stumble to a panel in the dark. If you're shopping for transfer switches for automatic backup, the choice usually comes down to how much you want to spend and how quickly the switch should move your load to a generator. Here, two automatic units face off: the Double Power Switch, Dual Power Automatic Transfer Switch and the GEYA Mini Dual Power Automatic Transfer Switch 2P 63A 110V For Grid & Generator. Both are automatic, so you don't have to stand by with a manual handle, but the details around included items and price set them apart.
Quick Verdict
If you want a stated conversion time of about 2 seconds, the Double Power Switch is the clearer pick. If you want a GEYA switch, the GEYA Mini fills that role. Neither is a bad match for an automatic backup, so the decision comes down to which package details you value.
