Thanks Cagey and mkc! I have a CyperPower that's worked well for a computer and haven't had to call tech support so I'll likely go with that. I've had APC before too and no complaints either.
About adequate power: I can't find any power requirements in the Lenni manual, maybe I'm just missing it. Does anyone have that info (I think it's a 2018 model)? I'll likely get a 1500 VA so I think that enough power, but still curious.
Also for dual conversion, I found an Opti UPS (they use the term double conversion) but those are expensive. I'm just looking to protect the Lenni in a power outage/surge. So I don't really care about any delay caused by a Sine Wave UPS to kick in. If that happens I'd just shut down and use it later. Any opinions on whether the Sine Wave UPS is more than adequate for protection? Or does dual conversion offer better protection?
