Grandstream
PSU-HT814PSU for HT814
The genuine Grandstream power supply for the HT814 four-port analogue gateway.
This one is worth holding as a spare rather than ordering when it fails. An HT814 usually has a fax, a lift phone or an alarm dialler hanging off it — things nobody thinks about until they stop working, and things that often go unnoticed for days. The adapter is the only part of that chain with no redundancy.
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 HT818?
The HT818 has its own listed supply — we stock it separately. Send us the model number if you are unsure.
Why keep a spare?
Because of what is usually plugged into an HT814: a fax, a lift phone, an alarm dialler. Those fail quietly, and the adapter is the only part of the chain with no backup.
