Do your Macs a favour by getting a UPS

• frankjr 2y ago
  Having a UPS makes sense but I've seen enough of those electric scooters going ablaze videos that I'm quite uneasy about having a pretty large battery under the table.

    The batteries in those scooters that burned up are lithium-ion, though, whereas the battery in a UPS will probably be something else.

  >The major exceptions to this are notebooks – MacBook Pro, MacBook Air, and MacBook – as their internal batteries provide their own backup power. As a result, if you do connect one of those to a UPS, it won’t be compatible with its USB connection that would otherwise be used to trigger shutdown when the mains supply is lost. Notebooks still benefit greatly from the filtered mains supply from a UPS, though. This doesn't sound right, is this the case? Wont a Mac laptop be powered through a UPS backup power? [edit] Ah, I think he just means the Mac laptop wont be getting the special over-USB signal a UPS can send that tells it "please shutdown, as the power wont last much longer". That's OK though, since if I have my laptop on UPS, I'm either there using it (so I can do that myself, if mains power is lost and before the UPS runs out) or it's configured to sleep after some inactivity anyway.

  > Although Mac power supplies are among the best I don't think there is data to support this claim.
