There’s also an implicit assumption that the power converters involved (in the UPS and the wall-warts) do not consume energy for their operation.Įven assuming the stated capacity is right, note that you’ll need to convert the DC voltage of the batteries to AC, which is later converted to DC again at the wall-warts for the router and monitor. Of course this is merely an upper bound on the runtime, under the assumption of 100% efficiency in energy conversion, new and fully charged batteries with the stated capacity (certainly not true for, say, many Chinese manufacturers of 18650 cells which claim absurd capacities like 10 Ah). Dividing one by the other, you would get about 5.6 hours of runtime, so your 10 hour figure is already off by a large amount. Your router presents a 6 W load and your monitor a 24.7 W load, so a total of 30.7 W. Though it is probably 12 V lead-acid, you should state it clearly just to be sure.Īssuming this is correct, then you have approximately 173 Wh of capacity. We also considered the number of outlets they had and whether there was sufficient spacing between them for wide plugs.A critical piece of information is missing here: battery voltage. We analyzed their specifications, like the input voltage, output capacity, battery runtime, and recharge time. We looked at how much power these devices supply, how much runtime they offer during power cuts, and their form factor (desk, tower, or rack-mount). We've tested these UPS machines across numerous points, starting with what environment they're best suited for - home, small office, or server farm? If your device takes a few minutes to turn off, make sure to select a UPS system that can provide sufficient runtime for that. Then, you'll want to assess how much power your devices require and how much time you need the electrical supply for once there's a power cut. There are some UPS machines that can be used both as towers or rack-mounts. While some are compact and can be fit on desks, others are larger and either in the form of towers or rack-mounts. You'll want to evaluate the size and form of the UPS system. When choosing a UPS for yourself, start with considering where you're going to use it - for your home or office? If it's a small home or office that you need to power, then a tiny UPS will work fine. Larger UPS systems can even last a few hours, but you generally won't find these in homes or small offices. Small UPS machines for homes and offices supply enough power for a few minutes, so there's time to turn off devices properly without losing any work. UPS stands for uninterruptible power supply, it's a device that acts as a battery backup in case of an electrical power failure. Check out our list of the best workstations to plug into a UPS.For office use, with lots of power-sapping devices that need to be powered at once, then you'll want to look elsewhere on this best UPS list, but for home users on a budget, this is a great choice. With careful management, you can keep the power flowing to a router or monitor for enough time to overcome most power cuts. That's thanks to its small and unobtrusive design, and it offers enough power for smaller devices, such as home NAS drives, routers, and gaming consoles.Īlthough it has only one USB port, it has plenty of sockets with sufficient spacing between them so that you won't have any difficulties connecting multiple wide plugs. This is another great UPS from APC, and with the BE600M1, the company has created a UPS device that is ideal for home use.
