Step 1: Check Your Device

Start by checking what your device supports:

• **Phones**: Most support 20–30W PD fast charging
• **Tablets**: iPad Pro supports up to 30W; iPad Air ~20–30W
• **Laptops**: Check the original charger wattage (45W, 65W, 100W, 140W)
• **Multiple devices**: Add up the power needs

Step 2: Choose the Wattage

Match the charger wattage to your most power-hungry device:

• **20W**: Phones and earbuds
• **30W**: Phones and small tablets
• **45W**: Ultrabooks (MacBook Air)
• **65W**: 13–14″ laptops (most popular)
• **100W**: 15–16″ laptops and multi-device
• **140W**: MacBook Pro 16″ fastest charging (PD 3.1)

A higher-wattage charger is always safe — it only delivers what your device requests.

Step 3: Consider Ports

• **Single port**: Smallest, most affordable — for one device
• **Dual port**: Charge two devices (laptop + phone)
• **Triple port**: Charge laptop + phone + tablet simultaneously

Multi-port chargers distribute power intelligently. Check the power distribution specs.

Step 4: Look for GaN

Choose GaN over silicon for:

• Smaller size (40–50% smaller)
• Cooler operation
• Higher efficiency
• Better reliability

GaN II (Navitas) is the latest generation with the best performance.
