Manufacturer description

The APC BE850M2 Back-UPS pairs 850VA / 450W of battery backup with 354-joule surge protection, making it a practical guard for a retro PC bench, a home office, or a small-business workstation that cannot afford an abrupt shutdown. Nine NEMA 5-15R outlets split the job: six give you battery backup plus surge protection for the machine, monitor, and external drive you actually need to survive an outage, while three surge-only outlets absorb the printer, speakers, and chargers that do not warrant runtime. Two USB charger ports share 2.4A, so a phone or tablet tops up without stealing a wall…

SpecPicks Verdict

SpecPicks scored APC UPS Battery Backup & Surge Protector with USB Charger using a rating × review-volume × price-fit model applied to published specs and reviews across the power protection category. APC's power protection lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power protection of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How much equipment can the BE850M2 actually run?

It supplies 850VA / 450W, so total connected load on the six battery outlets must stay under 450 watts. A desktop, monitor, and router fit comfortably; a 450W-plus gaming build does not.

How many of the 9 outlets have battery backup?

Six of the nine NEMA 5-15R outlets provide battery backup plus surge protection. The remaining three are surge-protection only, intended for printers, speakers, and other non-critical gear.

Can I replace the battery myself when it wears out?

Yes. APC rates the battery for 3-5 years and sells a replacement as part number RBC17, purchased separately, so you swap the cell instead of the whole unit.

What warranty and equipment coverage does APC include?

APC backs the BE850M2 with a 3-year warranty plus a connected-equipment policy. Review APC's policy terms on the product listing for current coverage limits and claim requirements.

Does it work with a Mac, and do the USB ports charge a phone?

The free power-management software is Windows-only; macOS uses its native Energy Saver settings. Two USB charger ports share 2.4A for phones and tablets.
