Mango Fast Charger 18W P300

Specifications

• 9V at 2A (9V × 2A = 18W)
• 12V at 1.5A (12V × 1.5A = 18W)
• 5V at 3A (5V × 3A = 15W) – Sometimes included, though slightly under 18W, this is the maximum for the standard 5V USB output.
• Some chargers using QC 3.0 may support a variable voltage output in small steps (e.g., from 3.6V up to 12V) to optimize charging efficiency.

Supported Fast Charging Protocols

The “fast” part of the charger depends on the charging protocol it supports. Common protocols for an 18W charger include:

• USB Power Delivery (USB PD): This is a universal standard, often supporting the 9V/2A and 12V/1.5A profiles to hit 18W.
• Qualcomm Quick Charge (QC) 2.0 or 3.0: These protocols also typically support the 9V/2A (QC 2.0/3.0) and 12V/1.5A (QC 2.0/3.0) levels.

15watt

• Normal Charge Output (5V):
  • 5 Volts (V) at 3 Amps (A)
    • (5V×3A=15W)
• Fast Charge Output (Higher Voltage):
  • 9 Volts (V) at 1.67 Amps (A)
    • (9V×1.67A≈15W)

Notes

Maximum Power
15W (Watt)
The total maximum power the charger can deliver.

Normal Voltage/Current
5V / 3A
Standard USB Power Delivery (PD) and the fallback for most devices.

Fast Charge Voltage/Current
9V / 1.67A
Common for Quick Charge and Samsung’s Adaptive Fast Charging (AFC) to reach 15W.

Input Voltage
100-240V AC
Standard universal input for global use.

Charging Protocols
USB PD, QC 2.0/3.0, AFC
The charger and the device use these protocols to “negotiate” the highest safe charging speed (voltage and current).
