Quick answer: Choose a fast charger by the phone manufacturer’s documented requirement, compatible charging protocol, suitable cable and sound physical condition. Do not buy only by wattage. USB-C Power Delivery, PPS and proprietary standards are not interchangeable in every situation.
Five-step selection method
- Identify the exact phone model.
- Read the manufacturer’s charging guidance.
- Match the protocol and adequate wattage.
- Use the correct connector and cable rating.
- Check the plug, socket fit, package and written seller terms.
Common charging standards
| Term | What it means for buyers |
|---|---|
| USB Power Delivery | A USB-C power-negotiation standard used by many phones, tablets and laptops |
| PPS | An adjustable USB PD feature used by some devices, including supported Samsung charging modes |
| Proprietary fast charging | May need the phone maker’s compatible adapter and cable |
| GaN | A charger design technology; it does not by itself prove protocol support or quality |
Stop using a charger when
- The casing or pins are damaged.
- The cable insulation is split or the connector is loose.
- Charging repeatedly disconnects after checking the device and socket.
- You notice arcing, smoke, burning odour or abnormal deformation.
Warmth can occur during charging, especially at higher power, but severe or worsening heat needs investigation. Unplug damaged equipment and seek qualified advice rather than continuing to test it.

Frequently asked questions
Is a 65W charger automatically faster than 25W?
No. The phone’s supported protocol and power limit control the result.
Is GaN always safer?
No. Evaluate the complete product, model, protocol, construction and documentation.
Can a damaged cable slow charging?
Yes. A worn connector or unsuitable cable can limit or interrupt charging and should be replaced.
