T POWER 12V 4.7A Charger for Ubiquiti Unifi Security Gateway

Power replacement: a T POWER 12V 4.7A AC adapter designed to safely replace the original adapter for Ubiquiti Unifi Security Gateway and compatible Juniper SSG/SRX320 devices.

If your network gateway needs a reliable replacement power supply, this T POWER adapter delivers the same 12V DC output and adequate current for stable operation. Built to work with a wide AC input range (100–240V), it’s made for global use and fits many legacy Ubiquiti and Juniper gateway models that require a round-barrel 12V plug. The unit is new, tested for consistent voltage delivery, and intended as a straightforward swap for worn or missing adapters.

Which devices will this T POWER adapter work with?

This adapter is compatible with several Ubiquiti and Juniper gateway models that accept a 12V, 4.7A barrel connector. It’s meant specifically for units that require a single-round-pin plug and is not for models needing 48–54V or four-prong connectors.

• Ubiquiti Unifi Security Gateway (USG) series
• Juniper Gateway SSG-5 variants (SSG-5-SB-W-US, SSG5-SH-M, SSG-5-SH)
• Juniper SSG family (SSG20, SSG-20-SB, and related SSG-5 series)
• Juniper SRX320-POE 6-port and desktop SRX320 appliances that accept 12V DC

How do I confirm this adapter matches my gateway?

Check the voltage, current rating, and plug style on your original adapter or device label before purchasing. Look for a 12V DC output specification, at least 4.7A capacity, and a round-barrel plug tip to ensure correct fit and safe operation.

• Verify device label shows 12V DC output.
• Confirm minimum current requirement is 4.7A or lower; higher capacity is acceptable.
• Ensure plug type is the round barrel tip, not a four-prong or RJ-style connector.
• Check the AC input range (100–240V) for international compatibility.

What safety and usage details should I know?

The adapter accepts 100–240V AC input and outputs a regulated 12V DC at 4.7A. Use only with devices that specify those electrical requirements; using incorrect voltages or connector types can damage equipment and void warranties.

• Input: AC 100–240V for worldwide power compatibility.
• Output: DC 12V with 4.7A maximum current delivery.
• Connector: round barrel plug tip—confirm physical fit before connecting.
• Not suitable for devices needing 48–54V or four-prong connectors.

How simple is installation and what can I expect after swapping?

Installation is plug-and-play: unplug the old adapter, connect the T POWER unit, and power up the gateway. Expect normal startup behavior and continuous operation if your device is healthy; monitor for stable LED indicators and normal performance after the swap.

• Unplug power from your gateway before switching adapters.
• Match polarity and ensure the barrel connector inserts snugly.
• Power on and observe status LEDs for proper boot sequence.
• If issues appear, recheck compatibility and connection integrity.

Who is this for: network administrators, IT technicians, small-business owners, and home lab enthusiasts who need a dependable replacement power adapter for Ubiquiti Unifi USG or compatible Juniper SSG/SRX gateways. It’s tailored for anyone replacing a lost or failed adapter who requires a 12V, 4.7A output with a round-barrel connector and broad AC input compatibility.
