PSU for HT818

The genuine Grandstream power supply for the HT818 eight-port analogue gateway.

Eight analogue devices depend on this one adapter. On a small hotel, a surgery or a factory floor that is likely to include a fax, a lift phone and an alarm dialler alongside the handsets — all of which fail silently. A spare on the shelf costs less than the afternoon spent working out why nothing on the analogue side is answering.

Use the correct adapter. Voltage and polarity vary across the Grandstream range, and a generic supply of roughly the right size can damage the gateway.

Frequently asked questions

Can I use any adapter of the same size?

Better not to. Voltage and polarity differ across the range and the wrong supply can damage the gateway.

Will it fit the HT814 or HT812?

Those have their own listed supplies — we stock them separately. Send us the model number if you are unsure.

Why keep a spare?

Eight analogue devices hang off one adapter, and the ones that matter most — lift phones, alarm diallers, fax lines — fail quietly. Nobody rings to tell you the lift phone is dead.
