Compact standby UPS for desktop and networking gear

The CyberPower EC550G is a 550 VA / 330 W standby UPS with simulated sine wave output designed to keep desktop computers, workstations, networking devices and home entertainment systems running during brief outages. It provides eight NEMA 5-15R outlets, a USB communication port and RJ11 phone line protection in a compact 120 V package.

Standby topology with ECO mode and GreenPower

The unit operates on standby topology and includes an ECO mode that automatically cuts power to designated outlets when the connected computer is off or asleep, reducing energy consumption. GreenPower UPS technology further lowers power draw through a high-efficiency charger and inverter, while full-time surge protection rated at 526 joules guards equipment continuously.

Replaces basic surge strips lacking battery backup

This UPS upgrades a standard power strip by adding battery runtime of 2.4 minutes at 300 W or 7.35 minutes at 150 W, enough for a controlled shutdown via the included PowerPanel Personal software. It is not suited for loads exceeding 330 W, for equipment requiring pure sine wave output or for installations needing extended runtime beyond a few minutes.

Questions about this item

How do I set up the EC550G and which step is often missed?

Plug the NEMA 5-15P cord into a grounded 120 V wall outlet, connect equipment to the eight NEMA 5-15R outlets, then install PowerPanel Personal and link the USB cable so the software can manage automatic shutdown.

What maintenance will the EC550G need over time?

The sealed lead-acid battery typically requires replacement after three to five years; recharge takes eight hours after each discharge cycle.

What limit appears first during a long outage on the EC550G?

Battery runtime is the limiting factor: 2.4 minutes at 300 W or 7.35 minutes at 150 W before the unit shuts down.
