Full Product Description

Bridge the Gap Between Your Device and HK Wall Sockets

Have you purchased a new telephone, fax machine, or dial-up modem, only to find the plug doesn't fit your wall socket? This is a common issue in Hong Kong. Most modern electronics use the global standard "US-style" square plug (RJ11), while many Hong Kong homes and offices still utilize the traditional "British-style" flat socket (BT/BS 6312).

The Sun Cheong Solution: Our BT Male to RJ11 Female Adapter is the missing link. It is a high-quality, passive converter designed to solve this incompatibility instantly without the need for rewiring or technician visits.

 

Why Choose This Adapter?

  • Universal Compatibility: Whether you bought a Panasonic phone from Amazon US or have a specialized fax machine, this adapter ensures it connects seamlessly to Hong Kong’s fixed-line network.
  • Zero Signal Loss: Cheap adapters can introduce static or reduce internet speeds. Our unit is built with high-grade internal wiring and sturdy contact points to maintain the integrity of your voice calls and data transmission.
  • Compact & Tidy: The minimalist white design blends perfectly with standard wall plates, keeping your workspace or home setup looking professional and organized.

 

How It Works

  1. Plug the Male end (the flat, wide connector) into your wall socket.
  2. Plug your device's RJ11 cable (the small square connector) into the Female end of the adapter.
  3. You are connected. No software, no batteries, no hassle.

FAQ Section

Q: Will this work with my broadband modem?
A: Yes, if your modem cable has a small square RJ11 plug and your wall socket is the flat rectangular type, this adapter is exactly what you need to make the connection.

Q: Does this adapter convert voltage?
A: No, this is a passive physical adapter. It connects the pins from one shape to another. It does not change voltage, but standard telephone line voltage is universal for these plug types.

Q: My phone cable has 2 pins, but the adapter has 4. Will it work?
A: Absolutely. This adapter supports up to 4 wires (6P4C). If your device only uses 2 wires (6P2C), it will simply use the two center pins, ensuring full compatibility.
