Apologies if this should be in a different forum, e.g. "power supplies."
I have owned quite a few backup power supplies. Just picked up a CyberPower LX1500GU for a special purpose: leaving plugged in to maintain charge, but with no load. Then I can put it where needed during a power outage, when another UPS runs out of battery charge or some small appliance needs juice.
Turns out that this doesn't work. I called Cyberpower, and the tech explained that this model has a "cold start lockout." I pointed out that this limits utility, even if for just a fraction of buyers.
As an experiment, I tried powering the UPS with a small 18650 battery inverter. The Cyberpower unit turned on, and stayed lit even after disconnecting the inverter. So that's a kludge workaround.
I'm trying to decide whether to return the unit and get another, or just live with it. I know that some UPS models can be cold-started, but manufacturers don't seem to advertise this feature/lack. Can anyone point to a master list of cold-startable backup power supplies?
Thanks!
