APC Back-UPS ES 400VA review

Verdict:

A straightforward UPS if you don't need automatic safe shutdown. It's cheap and has standard sockets, but Trust's 600VA is even cheaper and lasts longer.

Our Rating 3 stars out of 5

This model looks similar to APC's Back-UPS ES 700VA, but has a much lower power rating and fewer features. Like the ES 700VA, it's designed for home use, and its 400VA and 240W rating is enough to power a low-end PC.

In common with its higher-rated sibling, the ES 400VA has four battery backup sockets and four surge protection sockets. The sockets are all standard UK 3-pin, so you can plug in any electronic device. You can also protect against phone line and network surges with the RJ-11 phone line and RJ-45 Ethernet cable sockets. However, the ES 400VA has no USB PC connection, so it can't control your PC in the event of a power cut.

The ES 400VA kept our test PC going for the shortest time in the group: just 12 minutes at idle, and five minutes and nine seconds during the stress test.
