Do you recommend buying an UPS for Tivo?

    I just my XL4 and my HTPC on a UPS. It seems to last a bit over an hour (APC 1500VA). I plan to get a Home Theater UPS eventually, and move this one to a future desktop computer. It's mostly for piece of mind for power cycling and brownouts when the power goes out or comes back on. It's possible it could continue recording during an outage, but imagining Comcast staying on while the power is out is a real stretch of my imagination...

    I'm renting now, but I'd eventually like to have a UPS for my router and modem/ONT, future desktop PC and TiVo/HTPC at a minimum...

    When I had Comcast, it would always be on during a power outage. While at my brothers place, his Comcast signal goes out during a power outage.

    It depends on what the nodes and amps are powered off of... I don't really care, it's just to protect my equipment.

    My Comcast TV and Internet will generally stay up when the power's out. (And with local UPSs, so will my powered amps, tivos, routers, switches, wap, and computers).

    But the TV signal staying is just a convenience, if it went out and put a hole in my recordings, so be it. The UPSs are there to protect the Tivos, and everything else.

    Although the internet staying hot keeps me going from insane...

    haha. I usually go online if the power goes out too. Except that my laptop battery is completely worthless now. So much for the claimed "1000" cycles. Mine is completely dead at 196 cycles. So I use my iPad tethered to my iPhone, since my router and modem go dead with the power...

    1000 cycles is probably under highly optimal conditions (low temperature, low depth of discharge, etc.).

    Apple claims specifically that the internal batteries in the Unibody Macbook Pros will retain 80% of their charge capacity at 1000 cycles. Mine is at 1% at 196 cycles. They're probably not going to do anything, because it's considered a "consumable", which would be fine, except for the fact that they specifically marketed 80% charge capacity at 1000 cycles.

    Surge protectors are false security. Unless you're going to go with a full-sine double-conversion UPS or power conditioner, you're wasting your time.

    No UPS will protect your equipment from lightning strikes. The only protection is a lightning rod standing taller than anything else and a cable leading straight to the ground.

    Back a few years ago, we had a lightning strike close to the house and a surge came in through the lines. All of the electronics we had that were hooked up to your average surge protectors survived and everything that wasn't on a surge protector got fried. I know that is purely anecdotal, but even the cheapest surge protector is still probably better than nothing at all.

    Most surge protectors use MOVs which have limited limited lifetimes and deteriorate during that period. And there's no way to verify their condition. Even UL1449 3rd edition allows considerable voltage through before clamping, and there can be a significant spike beyond that due to latency.

    Cheap UPSs have little to no power conditioning and are really there to provide emergency power. And even that is questionable - unregulated square or stepped sine.

    There are good surge protectors (that don't use MOVs) and UPSs, but very few are willing to spend the money on them.

    Nobody mentioned surge supression on the cable line.

    I would think that's more important because a blown power supply is easy to replace but the boxes with damaged tuners are not repairable.
