Here is a detailed breakdown of the Original Realme 120W Type-C Charger Adapter and its advertised compatibility:

  Features and Technology

• Max Output Power: 120W (Watts).¹

• Charging Technology: Uses Realme's proprietary SUPERVOOC (or sometimes branded as SuperDart) flash charging protocol.² This high wattage is achieved through advanced bi-cell battery design and proprietary chips in both the charger and the phone, modulating voltage and current (e.g., ³$11V/11A$ Max).⁴

• Adapter Port: Typically features a Single USB-A Port on the wall adapter (brick).

• Cable: Comes with a High-Current USB-A to USB Type-C Data Cable.⁵ To activate the full 120W speed, a dedicated, high-amperage cable (often 12A or higher) with authentication chips is mandatory.⁶

• Backward Compatibility: The charger is designed to be fully compatible with older, slower Realme protocols like 65W SuperDart/SuperVOOC, 33W SuperVOOC, 18W Quick Charge, and standard 5V/2A charging. It will automatically detect and deliver the maximum power supported by the connected device.⁷

 Technical Specifications (Typical)

• Input: ⁸$100-240V\sim 50/60Hz$ (Supports global voltage standards)⁹

• SUPERVOOC Output (Max): Up to ¹⁰$11V/11A$ (120W Max)¹¹

• Standard Outputs: $5V/2A$ and other fixed-rate outputs for non-compatible devices.

 Compatibility Notes (Crucial Distinction)

The list provided is broad and includes phones with vastly different charging capabilities. The charger will work with all of them, but the charging speed will be limited by the phone's hardware, not the charger's maximum output.¹²

Key Takeaway: You can safely use this 120W charger on a Realme C33 (which supports 18W) without damaging the battery, but the phone will only charge at its maximum supported 18W speed. The 120W speed is reserved for flagship and high-end Realme models designed for it.¹³

Safety Features

As an "Original" Realme product, it should include robust safety protocols to ensure safe and efficient charging, protecting the device from:

• Over-Voltage Protection

• Over-Current Protection

• Over-Power Protection

• Short Circuit Protection

• High-Temperature Protection¹⁴
