How to Choose the Right USB-C Charger

Learn how to select the correct USB-C charger for your devices based on power delivery, wattage, and safety certifications to ensure optimal charging speeds.

1. Check your device wattage requirements. Consult your device manual or the manufacturer website to identify the required wattage. A charger with lower wattage than required will charge your device slowly or not at all, while a higher wattage charger will safely throttle down to the power your device needs.
2. Verify Power Delivery (USB-PD) support. Ensure the charger supports USB Power Delivery, the industry standard for fast charging. Look for the USB-PD logo on the packaging or technical specifications sheet to guarantee compatibility with your hardware.
3. Confirm GaN technology for efficiency. Select a charger utilizing Gallium Nitride (GaN) components. GaN chargers are significantly smaller, more efficient, and generate less heat than traditional silicon-based power adapters.
4. Examine safety certifications. Check the charger casing for safety marks such as UL, ETL, or CE. These certifications indicate that the device has undergone testing for short-circuit protection, overheating, and fire safety.
5. Account for port count and output. Decide if you need to charge multiple devices simultaneously. If you choose a multi-port charger, verify how the total wattage is distributed; some chargers split power equally, while others reserve higher output for a single primary port.
6. Match your charging cable. Use a cable rated for the wattage of your charger. A standard 60W cable will limit charging to 60W even if connected to a 100W+ charger; ensure your cable is E-Marked if you require power delivery over 60W.
