If you ever have to deal with power shortages and brief outages, Amazon’s offering all-time low prices on a four different sizes of of APC UPS backup power supplies, today only.

If you use a desktop computer, these will of course keep your machine running without any interruption in the event of a power outage, which means you won’t lose any unsaved work. But even if you only use laptops and mobile devices at home, they could still run lamps, your router and modem, or even a small TV until the power comes back on.


I think the sweet spot for most people will be the BX1000M, which can run at 100W for about 45 minutes, compared to just 29 minutes for the BX850M, which is only $5 cheaper. The two larger models should last 54 and 68 minutes at that load, respectively, but their prices are a bit more of a jump.
