What Is USB PD and How Does It Work?
USB Power Delivery (PD) is a communication protocol over USB-C that lets devices negotiate voltage (5V–48V) and current (up to 5A) for power up to 240W (PD 3.1). It is backward compatible: a PD charger can still charge older devices at lower speeds, but intelligent negotiation ensures optimal charging for each connected device. The USB-C connector is the physical standard that makes PD truly universal.
For OEM buyers, this means one charger design can serve multiple product lines. The protocol automatically detects the connected device’s requirements and delivers the exact power needed, preventing overvoltage or overcurrent. This reduces the risk of damage and improves user safety. Wecent integrates PD into all GaN charger platforms from 20W to 240W, ensuring reliable performance across smartphones, laptops, and more.
How Does PD Enable a Single Charger to Power Phones, Laptops, and Drones?
PD supports multiple power profiles (e.g., 5V/3A for phones, 20V/5A for laptops, 48V/5A for drones) within one charger. A 100W GaN PD charger can fast-charge an iPhone (20W), a MacBook Pro (60W), and a drone battery (100W) sequentially—or simultaneously with multiple ports. For B2B buyers, this means one SKU can serve multiple product categories, reducing inventory complexity and simplifying supply chain management.
This versatility is a game-changer for importers and private-label brands. Instead of stocking separate chargers for phones, laptops, and drones, you can offer a single universal PD charger that works across all devices. Wecent’s multi-port GaN chargers (up to 4 ports) intelligently distribute power, ensuring each device gets the correct profile. For example, a 100W 2C1A charger can power a laptop, phone, and earbuds simultaneously while maintaining fast charging speeds.
| Device Type | Typical Power Requirement | PD Profile Used | Example |
|---|---|---|---|
| Smartphone | 15W–30W | 5V/3A, 9V/3A | iPhone 15 (20W PD) |
| Ultrabook | 45W–65W | 20V/2.25A–3.25A | MacBook Air (45W) |
| Gaming Laptop | 100W–140W | 20V/5A–7A | Dell XPS 15 (130W) |
| Drone Battery Pack | 60W–100W | 12V/5A, 20V/5A | DJI Mavic 3 (65W) |
What Is the Difference Between PD and PPS, and Why Does It Matter for OEM Buyers?
PPS (Programmable Power Supply) is an extension of PD that adjusts voltage in fine 20mV steps for direct battery charging, improving efficiency and reducing heat. PPS is required for optimal charging of Samsung Galaxy S series, Google Pixel, and many Android devices. For OEM buyers, a PD charger that also supports PPS ensures broader device compatibility and fewer customer returns—especially important for Amazon sellers targeting mixed-platform audiences.

Weenc’s GaN chargers support both PD 3.1 and PPS, giving you maximum market coverage. Without PPS, some Android phones may charge slower or generate more heat. By including PPS in your product spec, you reduce the risk of negative reviews and returns. The cost difference is minimal, especially when leveraging Wecent’s pre-certified reference designs.
| Feature | PD Only | PD + PPS | Why It Matters |
|---|---|---|---|
| Device Coverage | iPhone, MacBook, most laptops | Adds Samsung, Pixel, OnePlus | Broader market = higher sales potential |
| Charging Speed | Fast (fixed voltage steps) | Optimized (fine voltage steps) | Less heat, faster top-off |
| Certification Requirements | CE, FCC, etc. | Same, plus PPS testing | Negligible extra cost |
| Typical Cost Difference | Baseline | +5–10% on BOM | Worth it for mixed-platform markets |
Why Should B2B Buyers Choose GaN + PD for Their Product Line?
Gallium Nitride (GaN) enables smaller, cooler, and more efficient chargers compared to traditional silicon—critical for high-wattage PD (65W–240W) without bulky heat sinks. GaN allows multi-port designs (e.g., 2C1A) that can share PD profiles intelligently, appealing to modern users who carry multiple devices. Wecent’s GaN platforms cover 20W to 240W and are engineered for PD 3.1 + PPS out of the box, backed by 15+ years of manufacturing experience and ISO9001 quality control.
For private-label brands and Amazon sellers, GaN + PD means you can offer a compact, high-power charger that stands out in a crowded market.

How to Reduce Inventory Complexity with a Single PD Charger Design?
A single 65W or 100W PD GaN charger can replace three separate SKUs (phone charger, laptop adapter, drone charger), lowering warehousing costs and simplifying logistics. For Amazon sellers, fewer product variations mean easier listing management, fewer stockouts, and less risk of mis-shipment. Cost-wise, producing one universal PD charger vs. three dedicated chargers often yields lower per-unit costs due to volume consolidation.
Consider Wecent’s manufacturing setup: a single 100W GaN PD charger with 2C1A ports can serve most of your customers’ needs. You only need to manage one SKU, one certification package, and one inventory line. This is especially valuable for brands selling in multiple regions, as you can include interchangeable plug heads or regional variants without multiplying SKUs dramatically.
Which PD Wattage Should You Choose for Your Application?
Quick guide: 20W–30W for phones and small tablets; 45W–65W for ultrabooks and standard laptops; 100W for gaming laptops and drone batteries; 140W–240W for workstations and high-drain devices. Choose wattage based on the highest-power device you need to support. PD negotiates down safely for lower-power devices. Wecent offers reference designs from 20W to 240W GaN PD, with customizable port configurations (1C, 2C, 2C1A, 3C, etc.).
For B2B buyers, we recommend starting with a 65W or 100W design as these cover the widest range of use cases. Wecent can tailor the exact wattage and number of ports to your target market. Our team can also advise on the best power distribution strategy to ensure all ports maintain fast charging when multiple devices are connected simultaneously.
Frequently Asked Questions
Can a USB PD charger damage my device if it delivers higher wattage?
No – PD negotiates the correct voltage and current between charger and device. A 100W PD charger will only deliver the maximum wattage the device requests (e.g., 20W for an iPhone). It is fully safe.
Do I need PPS if I am targeting only Apple devices?
PPS is not required for Apple’s proprietary charging (i.e., iPhone and MacBook use standard PD). However, if you plan to sell in Android-dominated markets (Samsung, Google), PPS support significantly broadens compatibility.
What is the minimum order quantity for a custom PD GaN charger from Wecent?
Our MOQ starts at just 200 pieces for standard OEM customization (logo, packaging, color). For fully custom power designs (Level 3), MOQ may be higher; please contact us with your requirements.
How long does it take to get a custom PD charger certified for the US and EU?
Typical lead time is 4–6 weeks for CE/FCC certification if the base design is pre-certified. Wecent can accelerate this because we already hold key certifications for our reference designs.
Can I use one PD charger for a drone that requires 12V/5A?
Yes – PD 3.0 supports 12V/5A (60W) and PD 3.1 extends to 48V/5A (240W). As long as the drone’s battery management system (BMS) supports PD negotiation, a single universal PD charger will work.
