Pros & Cons

Pros

✓ Six NEMA 5-15R outlets: 3 surge-only plus 3 surge + battery backup
✓ Roughly 6 minutes of runtime at half load (200VA/127.5W)
✓ Right-angle 5-foot plug with 45-degree offset avoids blocking nearby outlets

Cons

✗ Standby topology, not line-interactive, so no active voltage regulation
✗ Only 3 of the 6 outlets are actually battery-backed

Manufacturer description

The Amazon Basics UPS Battery Backup pairs a 400VA/255W standby topology with six NEMA 5-15R outlets, making it a practical guard for a retro PC bench, a home network closet, or a small entertainment stack. Three outlets deliver surge protection only, while the other three add battery backup, so you can split a CRT-era rig's monitor and speakers from the machine that actually needs to shut down cleanly. Runtime is deliberately modest and honest: roughly 6 minutes at half load (200VA/127.5W) and about 1.5 minutes at full load (400VA/255W). That is enough to ride out a brownout or save your…

SpecPicks Verdict

SpecPicks scored Amazon Basics UPS Battery Backup & Surge Protector using a rating × review-volume × price-fit model applied to published specs and reviews across the power protection category. Amazon Basics'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.

Frequently Asked Questions

How long will this UPS keep my devices running during an outage?

About 6 minutes at half load (200VA/127.5W) and about 1.5 minutes at full load (400VA/255W). Actual runtime scales with the power draw of whatever you plug in.

Can it power a gaming PC or a desktop with a dedicated GPU?

No. The unit is rated for 400VA/255W, and Amazon Basics recommends staying below 80% of that. It is intended for home networking gear, IoT devices, and home entertainment equipment.

Do all six outlets have battery backup?

No. Of the six NEMA 5-15R outlets, three are surge-protected only and three are surge-protected with battery backup. Put your router, modem, or PC on the backed-up trio.

Does it support automatic shutdown of a connected computer?

Yes. Power management software is available for download from the Product guides and documents section of the Amazon listing, which lets a connected system shut down cleanly before the battery runs out.

What does the power cord look like and how long is it?

It is a 5-foot cord with a NEMA 5-15P right-angle plug and a 45-degree offset, rated 120V at 50Hz or 60Hz, so it sits flush against the wall without blocking the neighboring outlet.
