Best Uninterruptible Power Supplies of 2026

Two units in this group are rated 1,500VA. The BX1500M turns that into 900 watts of usable output, and the gap between those two figures is the most useful thing to understand before buying any of these: VA is the number on the box, watts are what your equipment draws. Nine hundred watts still clears a gaming PC, a couple of monitors, and the networking gear on the same shelf.

Ten outlets is the argument for it. Five are battery-backed and five are surge-only, which is the right split for a crowded desk: the tower, the monitors, the speakers, and the router get backup, while the lamp, the spare charger, and the printer stop competing for runtime. If you have ever unplugged a lamp to make room for a modem, this is the fix.

We like that the battery is a replaceable module rather than a sealed assembly, so a five-year-old unit gets a fresh pack instead of a trip to the recycling center. AVR corrects brownouts without leaning on the battery, and the quoted runtime of 68 minutes at 100 watts is the longest figure in this set attached to a specific load.

The detail worth knowing about is the data-line protection. Coaxial and Ethernet both pass through the unit, so a surge arriving on the cable or DSL line has somewhere to go besides your modem's internals. Most people protect the outlet and forget the wire coming in from the pole.

Twenty-three minutes is the runtime on the box, quoted at 100 watts, and that is the honest way to read any UPS claim. For what this unit is built to do — keep a modem, a router, and the optical box on the wall alive — the load sits well under that ceiling, so the minutes stretch. That is why it is our pick for the small, thankless job of keeping the internet up.

Five outlets sit on battery and two on surge, which is a sensible count for a shelf of network gear. The 1.5A USB port keeps working during an outage, so a phone gets charged while the lights are out, and the battery is user-replaceable — a four-year-old unit gets a fresh pack rather than becoming e-waste.

At 7.5 pounds and about eleven inches wide, it disappears next to a router. The ceiling is 330 watts, which is a network shelf or a light desktop rather than a tower with a graphics card, and the three-year repair-or-replace cover is what you lean on if the pack ages out early. That is the trade for something this compact.

Lithium iron phosphate in a UPS is still uncommon enough to be the headline. GOLDENMATE rates this pack at over ten years, where the lead-acid units in this set are rated around three, and it delivers 800 watts of pure sine wave output — the same waveform the top pick uses, generated from a battery that works differently.

5.6 kilograms is the number that surprised us. That is about twelve and a half pounds for 800 watts, roughly half the weight of the 1,500VA towers here, and it changes something as ordinary as getting the thing onto a shelf or out from behind a desk. Anyone who has hauled a dead 25-pound UPS out of a cable nest will notice.

All eight outlets are battery-backed and surge-protected, which is more than most units here give you, and the color LCD reports load and battery state the way the CyberPower does. Setup is one button and a cord; nothing needs configuring before it starts protecting. The housing is white, a small thing until you are trying to hide a black brick on a pale shelf in a home office.

Two of its outlets are spaced wider than the rest, and that small detail says who this unit is for: gear that arrives with a chunky adapter brick and a short cord. At 2.76 inches deep and 6.8 pounds, the SL700U goes where the gear goes — a shelf behind the television, a telco cabinet, the narrow ledge under a standing desk — instead of on the floor. That is why it is our pick when space is the constraint.

Inside that thin case is 700VA and 370 watts, split across five battery outlets and three surge-only ones, with 890 joules of surge protection. Two USB charging ports share 2.4 amps, enough for a phone and a set of earbuds, which saves an outlet you would otherwise spend on a wall adapter.

370 watts is the honest ceiling: a router, a switch, a modem, a television, or a light desktop is fine, and a gaming tower is not. Within that range it does what a good UPS should, which is disappear into the furniture and only make itself known when the power drops.

USB-C charging and an RJ45 jack are an unusual pair to find on a UPS this small, and together they say what this one is for: the shelf where the internet enters the house. The line from the wall passes through the unit, phones and tablets charge from the front ports, and the modem and router sit on battery outlets behind.

Five of the seven outlets are battery-backed, two are surge-only, and automatic voltage regulation handles the brownouts that make a router reboot for no apparent reason. The battery is replaceable rather than sealed in, and the whole unit weighs eight pounds, so it sits on a shelf without anyone noticing it is there.

For a network shelf — ONT, router, a switch, a camera hub — the load sits far below the unit's rating, and the port cluster means one fewer charging brick and one fewer strip up there. The AVR earns its keep in an older house where the lights dim when the dryer starts. You are paying for the ports and the shape rather than raw capacity; the APC BE600M1 above delivers more watts for about the same money.
