Grandstream 12V-1.5A Power Supply
Frequently Asked Questions
First, confirm the outlet you are using is live by testing it with another device like a lamp or phone charger. Next, ensure the barrel connector is pushed completely into the phone’s power port until it clicks or sits flush; a loose connection is a common cause. If the phone still shows no signs of life, try a different power outlet in the room to rule out a faulty wall socket.
No, this specific 12V-1.5A adapter is not intended for the GXP2170 and is not listed as compatible. Using an incorrect power supply, even if the plug physically fits, can deliver the wrong voltage and permanently damage the phone. You should locate the adapter that matches the power requirements printed on the back of the GXP2170 or use a compliant Power over Ethernet connection.
Begin by verifying that the adapter you are using is this specific Grandstream 12V-1.5A unit and not a third-party supply with a lower amperage rating. An underpowered adapter can cause the system to reboot under load. Also, check that the power cable is not pinched or tightly bent, and plug the UCM directly into a wall outlet rather than a daisy-chained power strip to ensure it is getting clean, stable power.
Yes, this power supply is designed for the US models of the listed devices, and Canadian deployments use the same hardware variants and power standards. It will work correctly with a standard North American outlet. The compatibility list is the critical factor, not the country of purchase, so just confirm your phone or appliance model is among those listed.
It is normal for a power adapter under load to feel warm, particularly when powering a device like a UCM or a video phone for extended periods. However, if it becomes too hot to hold comfortably or you notice a burning smell, unplug it immediately from the wall. As a safe first step, ensure the adapter is in a well-ventilated area and not buried under papers or inside a cable nest that traps heat.
To isolate the power supply as a potential cause, try powering the phone using a different, known-good adapter of the exact same specification, or temporarily relocate the phone to a PoE port if available. If the static disappears on the alternate power source, the adapter may be introducing electrical noise. Also, check that the power cable is routed away from audio and network cables, as close parallel runs can sometimes induce interference.
The barrel connector should fit snugly. First, inspect the power port on the HT818 for any debris or damage and ensure the adapter’s plug is fully inserted. A loose fit can cause intermittent power loss and unexpected reboots. If reseating the connection firmly doesn't help, try the adapter on another compatible device from the list to determine whether the loose fit follows the adapter or stays with the HT818.

About This Product
The Grandstream 12V-1.5A power supply is a straightforward replacement or spare AC adapter for a specific set of Grandstream desktop endpoints and appliances. It is not a universal charger; its value lies in matching the exact voltage and amperage requirements of the listed devices, which include several popular executive video phones, the UCM series of IP PBXs, and analog telephone adapters. For a business with a fleet of GXV series phones, keeping one or two of these on hand makes sense as an insurance policy against a lost or failed adapter that could sideline a user’s primary communication tool.
This unit is appropriate for any environment where the supported devices are deployed, from a small office with a single UCM6301 to a larger rollout of GXV3470 phones across a Toronto-area floorplan. It is the correct adapter when the original has been misplaced during a desk move or damaged by a spill. The compact, in-line design fits easily into typical cable management setups without hogging space on a power bar.
A buyer should understand what this adapter does not cover. It is not intended for Grandstream models that rely on Power over Ethernet, nor for smaller entry-level phones or gateways that use a different voltage or a micro-USB connection. It is also not a substitute for a PoE injector or switch. If your device is not on the explicit compatibility list, this adapter will not work and may cause damage. It is strictly a 12V accessory for the named US models.
For a single phone on a desk where PoE is unavailable, this adapter is a necessity. In a full-floor deployment where every drop is already powered by a PoE switch, purchasing a stack of these adapters would be overkill and add unnecessary clutter. It is best viewed as a targeted spare part, not a bulk provisioning item.
