Replacement adapter for VVX and SIP phones

This 5 V 3 A power adapter replaces lost or failed supplies for Poly VVX 150 250 350 450 Edge B E400 E300 Series E220 E100 EM50 and compatible Cisco SPA and Yealink T and MP models. It accepts 110 V to 240 V at 50 Hz to 60 Hz and ships with a 70 inch cord and five interchangeable DC plugs.

Upgrade from a single-tip brick

The included tips measure 5.5 by 2.1 4.0 by 1.7 4.8 by 1.7 3.5 by 1.35 and 2.5 by 0.7 mm so one unit covers multiple desk phones instead of keeping separate wall warts for each brand. The jump is worth it when a fleet mixes Poly Cisco and Yealink handsets and you want one spare that fits all.

Limited to barrel-connector devices

Output is fixed at 5 V 3 A through barrel jacks only so it cannot power USB-C phones PoE-only models or any device that needs a different voltage or connector polarity. The 70 inch cable also restricts placement to desks within roughly two metres of a mains socket.

Questions about this item

Which DC plug size from the 5.5×2.1, 4.0×1.7, 4.8×1.7, 3.5×1.35 or 2.5×0.7 mm set fits my Poly VVX 250?

The adapter includes five interchangeable tips — 5.5×2.1, 4.0×1.7, 4.8×1.7, 3.5×1.35 and 2.5×0.7 mm — so you can select the one that matches the phone's jack.

What is the correct way to attach the chosen tip so the polarity stays correct?

Push the selected DC plug firmly onto the cable barrel until it clicks; the centre pin is positive, so align the tip's notch with the socket groove before seating it.

When should I replace the 70 inch cord or one of the five DC plugs?

Replace the cord if the insulation cracks or the plug pins bend, and swap a tip when its barrel becomes loose or the centre pin no longer springs back.
