Slow charging is usually down to a mismatched charger, cable or phone setting. This guide explains the basics so you can charge faster and safer.
Wattage explained
Watts tell you how quickly a charger can deliver power. A 20–30 W charger suits most phones, while laptops may need 65 W or more.
Cables and standards
USB-C Power Delivery (PD) is the most widely supported fast-charging standard. Use a cable rated for the wattage you want.
Power banks
10,000 mAh is a good balance of size and capacity for daily use, while 20,000 mAh suits travel. Look for PD output if you want fast charging on the go.
GaN chargers
GaN chargers are smaller and run cooler than traditional ones, and a single 65 W GaN charger can power a phone, tablet and laptop.
Final thoughts
Match your charger, cable and power bank to your devices, and keep an eye on the warranty. Genuine accessories last longer and charge safer.
