Oddbean new post about login | logout @af151d0b Uninterruptible Power Supply. So when there’s a power blip or outage a battery takes over and your machines don’t crash/reboot and your internet connection stays up.
@9c01cb3c Ah. I always see them being advertised on Facebook marketplace but they’re broken ones
@af151d0b Yeah standard ones all use Lead Acid batteries that die after 2-3 years at which point they become toxic waste that's difficult to dispose of. You can get a dead marketplace one and replace the battery easily but the replacement battery is 2/3 the cost of a new device so not worth the risk of getting a bad device. Which is why I wish Li-ion DC ones were common. It could literally be the price of a generic USB battery bank. And Li-ion if lightly used could last a decade
