Power Delivery vs Quick Charge: What's the Difference and Which Is Better?
You've seen the terms on charger boxes: USB Power Delivery, Quick Charge 3.0, Quick Charge 4+. They both promise fast charging — but they're fundamentally different technologies, and using the wrong one for your device means you're leaving speed on the table. Here's everything you need to know.
What Is USB Power Delivery (USB-PD)?
USB Power Delivery is an open, universal fast-charging standard developed by the USB Implementers Forum (USB-IF). It works over USB-C and allows devices and chargers to negotiate the optimal voltage and current for the fastest possible charge.
Key facts about USB-PD:
- Maximum power: Up to 240W (USB PD 3.1)
- Connector: USB-C only
- Compatibility: Works with any USB-PD certified device, regardless of manufacturer
- Voltage range: 5V, 9V, 15V, 20V, and 28V/36V/48V (PD 3.1)
- Who uses it: Apple (iPhone 8+, MacBooks), Google (Pixel), Samsung (Galaxy S series), Nintendo Switch, Steam Deck, most modern laptops
What Is Qualcomm Quick Charge?
Quick Charge is a proprietary fast-charging standard developed by Qualcomm, designed for devices using Qualcomm Snapdragon processors. Unlike USB-PD, Quick Charge is a closed ecosystem — it works best when both the charger and the device are Quick Charge certified.
Key facts about Quick Charge:
- Maximum power: Up to 100W (Quick Charge 5)
- Connector: USB-A or USB-C
- Compatibility: Primarily Android devices with Qualcomm Snapdragon chips
- Voltage range: 3.6–20V (adaptive)
- Who uses it: Samsung Galaxy (older models), OnePlus, Xiaomi, ASUS, many Android OEMs
USB-PD vs Quick Charge: Head-to-Head Comparison
| Feature | USB Power Delivery | Quick Charge |
|---|---|---|
| Standard type | Open (universal) | Proprietary (Qualcomm) |
| Max power | 240W (PD 3.1) | 100W (QC 5) |
| Connector | USB-C only | USB-A or USB-C |
| Cross-brand compatibility | Excellent | Limited |
| Laptop charging | Yes (up to 240W) | No |
| Apple device support | Yes | No |
| Android support | Yes (most modern) | Yes (Snapdragon devices) |
Which Protocol Does Your Device Use?
This is the most important question — and the answer determines which charger you should buy.
Devices that use USB Power Delivery:
- All Apple iPhones (iPhone 8 and later)
- All Apple MacBooks and iPad Pros
- Google Pixel phones (all generations)
- Samsung Galaxy S21 and later (also supports QC)
- Nintendo Switch and Switch OLED
- Steam Deck
- Most modern Windows laptops
Devices that use Quick Charge:
- Samsung Galaxy S20 and earlier
- OnePlus phones (older models; newer ones use USB-PD)
- Xiaomi phones
- ASUS ROG phones
- Many mid-range Android phones with Snapdragon chips
Can a USB-PD Charger Charge a Quick Charge Device (and Vice Versa)?
Yes — but not at maximum speed. USB-PD and Quick Charge are not directly compatible, but both protocols fall back to standard 5W USB charging when they don't recognize each other. So your device will charge, just slowly.
The good news: many modern chargers support both USB-PD and Quick Charge simultaneously. Our NexCharger 65W GaN Charger supports USB-PD on its USB-C ports, covering virtually every modern device. For Android users with older Quick Charge devices, look for chargers that explicitly list QC compatibility alongside USB-PD.
What About PPS (Programmable Power Supply)?
PPS is an extension of USB-PD that allows even finer voltage control — adjusting in 20mV increments rather than fixed voltage steps. This results in less heat during charging and faster speeds on compatible devices. Samsung Galaxy S21+ and later, and many recent Android flagships, support PPS.
If your device supports PPS, look for a charger that explicitly lists PPS support. Our Fast Charging Explained guide covers PPS in detail.
Which Should You Choose?
In 2026, USB Power Delivery is the clear winner for most people. Here's why:
- It's the universal standard — one USB-PD charger works for your iPhone, MacBook, Switch, and Android phone
- It supports higher wattage (up to 240W vs 100W for QC 5)
- It's the only standard that can charge laptops
- It's mandated by the EU as the universal charging standard
- Most new Android phones now support USB-PD in addition to or instead of Quick Charge
The only reason to prioritize Quick Charge is if you have an older Android device that doesn't support USB-PD. In that case, a charger with both USB-PD and QC ports gives you the best of both worlds.
Our Recommendation
For most households and travelers, a 65W USB-C PD GaN charger covers every device you own. The NexCharger 65W GaN Charger delivers full-speed USB-PD charging for laptops, phones, tablets, and gaming handhelds — in a compact, travel-ready package that works in 150+ countries.
If you need a more compact option for travel or light use, the GaN 20W Travel Adapter delivers 20W USB-PD — perfect for fast-charging phones and tablets on the go.

The Bottom Line
USB Power Delivery is the universal, future-proof fast charging standard. Quick Charge is a Qualcomm-specific protocol that's increasingly being replaced by USB-PD even on Android devices. For 2026 and beyond, a USB-PD GaN charger is the smartest investment — it works with everything, charges faster, and won't be obsolete next year.
