Product description

Description & Role

This is a dedicated external AC/DC power supply unit designed to provide 5 volts DC at 1 ampere output current — i.e., a 5 W rated adapter. For many Fanvil IP phones and devices that either don’t support Power over Ethernet (PoE) or where PoE isn’t available, this adapter supplies the necessary power.

It typically accepts a wide AC input (100‑240 V, 50/60 Hz) so it can work globally. WiFi.kz+1

Key Specifications

• Input Voltage: 100‑240 V AC, 50/60 Hz (universal input) Impuls Telekomunikacije+1

• Output Voltage: 5 V DC Impuls Telekomunikacije+1

• Output Current: 1 A (i.e., maximum ~5 W) starmount+1

• Connector Type / Polarity: For Fanvil socket (barrel style) — for example one listing says “Ø outside 5.4mm, Ø inside 1.7mm, length 10mm, centre‑positive” for certain markets. Impuls Telekomunikacije

• Certifications & Protections: It includes basic safety features like over‑voltage protection, short‑circuit protection. One Kenyan listing indicates CE/RoHS certified. starmount

Compatibility & Usage

• According to several reseller listings, the 5 V / 1 A adapter is compatible with Fanvil phones like X1, X2, X3S, X4, H3, H5 etc when those models are specified with “5 V/1A” input in their datasheets. Telco

• On Fanvil’s own datasheet for the H5 phone, the adapter input is listed as “DC Power Input: 5V / 1A”. Fanvil

• Not suitable for higher‑power Fanvil models that specify higher current (for example some phones specify 5 V/2A) — using an under‑rated adapter could cause malfunction. One reseller warns that if you have a model like X5, X6, etc you need a stronger adapter (5 V/2 A) instead. starmount

Benefits

• Simple & compact: It’s a straightforward, low‑power solution where PoE is unavailable or not used. Resellers note its compact footprint. starmount

• Global input voltage: With 100‑240 V input it can be used in many countries with appropriate plug adapter.

• Cost effective alternative: For phones that require low power, this adapter is less expensive than PoE‑enabled supply or high current alternatives.

• Safety certified: Listings emphasize short‑circuit protection, over‑voltage protection, compliance with CE/RoHS standards.

Things to Check & Considerations

• Ensure correct output current rating: If your Fanvil phone datasheet requires 5 V/2A (or more) and you use a 5 V/1A adapter you may get instability or device may not power on properly.

• Connector compatibility & polarity: Make sure the barrel plug size and polarity (centre positive) match your device. One specification details the plug dimensions. Impuls Telekomunikacije

• Use for intended devices only: Higher‑end phones with back‑lit displays, WiFi, Bluetooth or large screens may require more power.

• Ventilation and placement: While low power, the adapter should still be placed in well‑ventilated area; avoid covering it or subjecting it to high ambient temperatures.

• Quality & authenticity: Use genuine Fanvil or approved third‑party adapter to ensure compliance with safety and avoid damage to your device.

• Future‑proofing: If you anticipate upgrading to more feature‑rich Fanvil models, consider whether a higher rated power supply (5 V/2A) might be more appropriate.
