Match the Wattage

The most important factor is matching wattage to your laptop:

• **45W**: MacBook Air, ultrabooks with low power draw
• **65W**: MacBook Pro 13″, Dell XPS 13/14, ThinkPad X1, most 14″ laptops
• **100W**: MacBook Pro 16″ (at 100W), Dell XPS 15, 15–16″ laptops
• **140W**: MacBook Pro 16″ fastest charging (PD 3.1)

Using a lower-wattage charger than your laptop needs results in slow charging or battery drain during use. Using a higher-wattage charger is safe — the laptop only draws what it needs.

Check Compatibility

Ensure the charger supports:

• **USB-C PD** — the standard for modern laptop charging
• **Correct voltage** — most laptops need 20V (PD standard)
• **Your laptop’s specific PD profile** — check manufacturer specs
• **5A cable** — required for 100W+ charging

All USB-C PD laptops are compatible with Powgent GaN chargers, including Apple, Dell, Lenovo, HP, Microsoft, and ASUS.

Single vs Multi-Port

• **Single port**: Smallest, most affordable — ideal as a direct replacement
• **Multi-port**: Charge laptop + phone + tablet — ideal for desk or travel

Multi-port chargers distribute power intelligently. The laptop port typically gets priority.

GaN for Laptops

GaN is especially valuable for laptop chargers:

• A 65W GaN charger is ~50% smaller than the original silicon charger
• Runs cooler during sustained laptop charging
• Foldable plug makes it travel-friendly
• Higher efficiency saves energy

Replace your bulky original laptop charger with a compact GaN charger for a better experience.
