Genuine Avaya 1151D1 Power Supply for IP Phones - Reliable Injector

In this review the Genuine Avaya 1151D1 Power Supply for IP Phones is examined for buyers who need a dependable replacement injector for Avaya phones. The bottom line: this is a straightforward, no-frills 20 Watt power injector that restores power to legacy Avaya handsets with minimal fuss. For IT staff maintaining a small office or a tech replacing a failed unit on a shelf of phones, it delivers the specific compatibility and output those models require without unnecessary extras.

Key Features

• Compatible Models: Designed specifically for Avaya 4606, 4612, and 4624 IP phones to ensure direct fit and proper power delivery for those devices.
• Rated Output: Supplies 20 Watt power suitable for the targeted Avaya models, giving consistent operation for voice-only handsets.
• Power Injector Design: Acts as an inline power injector so it can be added to existing network cabling without replacing switch hardware.
• Genuine OEM Part: Being a genuine Avaya component reduces compatibility guessing and helps preserve warranty or support expectations where OEM parts are preferred.
• Simple Replacement: Installation is straightforward and intended for quick swap-out when a phone stops powering up.

Who It's For

This power supply is best for small business IT administrators, facilities teams, and repair technicians who maintain Avaya 4606, 4612, or 4624 phones and need a direct replacement injector. It suits situations where a reliable, OEM-rated 20 Watt source is required and where PoE-capable switches are not available or an inline injector is preferred.

Users who should look elsewhere include those who need multi-device charging, higher wattage for power-hungry PoE devices, or a universal injector with multiple outputs. For modern PoE switches or newer Avaya models, a network-grade PoE solution would be more appropriate.

Pros & Cons

Pros

• Genuine Avaya design ensures correct voltage and connector compatibility with supported IP phones.
• 20 Watt output is adequate for the targeted handset models, restoring basic phone functionality quickly.
• Inline injector form factor allows add-on power without replacing network switches or cabling.

Cons

• Limited to 20 Watt output and older handset models, so it is not suitable for newer, higher-power devices.
