Quick answer

Choose the NRGlink 45W Dual USB-C Wall Charger if you need to charge two devices quickly at once. Stick with a 20W charger if you only charge one phone at a time and want the smallest possible size.

Why wattage matters for USB-C charging

Wattage determines how fast your device can charge. A 45W charger delivers more power than a 20W one, meaning it can charge larger devices like tablets and laptops in addition to phones. However, not every device needs 45W—most smartphones top out at around 20W to 30W charging speeds.

The trade-off: speed vs. size

A 45W dual-port charger like the NRGlink is slightly larger than a single 20W brick because it houses extra circuitry and two ports. The benefit is you can charge a phone and a tablet simultaneously without slowing down. A 20W charger is more compact and lighter, making it easier to slip into a small pocket.

Which charger fits your routine?

  • NRGlink 45W Dual USB-C Wall Charger: Provides 45W total power and two USB-C ports. Ideal for charging a phone plus a tablet or laptop at full speed. Best if you regularly charge multiple devices or need laptop-level power.
  • Typical 20W USB-C Charger: Delivers up to 20W via a single USB-C port. Compact and lightweight, but can only charge one device at a time. Best if you charge only one phone and prioritize minimal size.
  • Compatibility check: Check your device's maximum charging wattage. Most phones cap at 20-30W; laptops may require 45W or more. Using a 45W charger on a phone that only accepts 20W won't harm it—the device negotiates the correct speed.
