Your phone supports fast charging. Your charger probably doesn't.
This is one of the most common — and most expensive — mistakes people make with their devices. They buy a fast-charging phone, then plug it into a $10 charger and wonder why it takes 3 hours to fill up. Let's fix that.
The Fast Charging Standards You Need to Know
USB-C Power Delivery (USB-C PD)
USB-C PD is the universal fast charging standard supported by Apple, Google, Samsung, and virtually every major device manufacturer. It allows chargers to negotiate the optimal voltage and current with your device, delivering up to 100W safely. The NexCharger 65W GaN Charger is fully USB-C PD compliant.
PPS (Programmable Power Supply)
PPS is an extension of USB-C PD that allows even finer voltage control — in 20mV increments — for more efficient charging with less heat. It's supported by newer Android devices including Samsung Galaxy S series and Google Pixel.
Qualcomm Quick Charge
Quick Charge is Qualcomm's proprietary fast charging protocol, found in many Android devices. While it's not the same as USB-C PD, many modern GaN chargers support both.
Why Wattage Matters
Wattage = Volts × Amps. The higher the wattage, the faster the charge — up to your device's maximum supported input. Here's a quick reference:
- 5W: Standard slow charging (old iPhone chargers)
- 18–20W: Fast charging for phones (the NexCharger 20W Travel Adapter hits this perfectly)
- 45–65W: Laptop-grade charging (the NexCharger 65W covers this range)
- 100W+: High-performance laptop charging
The Cable Problem Nobody Talks About
Even with a great charger, a cheap cable can bottleneck your charging speed. Always use a USB-C cable rated for the wattage you need. The NexCharger 65W includes a 1M C-to-C cable rated for full 65W delivery — no bottleneck.
How to Know If You're Fast Charging
On iPhone: Look for the lightning bolt icon next to the battery. On Android: Most devices display "Fast Charging" or "Rapid Charging" on the lock screen when connected to a compatible charger.
If you're not seeing that message, your charger isn't delivering fast charging — regardless of what the box says.
The Smart Upgrade
For most people, the NexCharger 65W GaN Charger is the only charger they'll ever need. It supports USB-C PD up to 65W, covers phones, tablets, and laptops, and includes interchangeable international plugs. For travel-focused users, the NexCharger 20W Travel Adapter is the perfect companion for fast-charging phones and tablets anywhere in the world.
