What makes a GaN charger different
A GaN charger replaces the silicon switch inside the power supply with gallium nitride. Gallium nitride switches faster and loses less energy as heat, so a GaN wall charger can be roughly half the size and weight of a silicon brick with the same rating while running cooler. For a 65W GaN charger or a 140W GaN charger that is the difference between carrying a laptop brick and carrying something close to the size of a phone charger.
Choosing the right wattage
Start from the device, not from the number on the label. Phones, earbuds and small accessories are comfortable at 20W to 45W. Thin-and-light laptops, tablets and handheld consoles usually need 65W to 100W. Gaming laptops, docking stations and desks that charge several devices at once are the 140W to 240W territory. Every model in this collection is grouped by output so you can compare like for like inside a power band — 20W-45W GaN chargers, 65W-100W GaN chargers and 140W-240W GaN chargers.
Ports, protocols and PPS
Count how many devices you want to charge at the same time and match the port mix: 1A1C, 2A2C, 2A3C and similar combinations are all available. Look for USB-C Power Delivery 3.0, and PD 3.1 on the higher wattages, plus PPS for Samsung fast charging and legacy QC or Apple 2.4A support. A charger that negotiates correctly delivers exactly what the device asks for — no faster, no hotter.
Plugs and certifications for different markets
EU, UK, US and AUS plug types can be built into one SKU or supplied as interchangeable travel adapters, which lets you serve several regions from a single order instead of several tooling rounds. Electrical safety approval is what decides whether a container clears customs: CE and RoHS for the EU and UK, FCC for the United States, and the regional equivalents elsewhere. Test reports travel with the shipment so your buyer can file them.
How to buy GaN chargers from the factory
WECENT is a GaN charger manufacturer in Shenzhen working in OEM and ODM mode. Branding — logo, colour, finish, cable, pouch and retail carton — starts from a 200 pcs trial order, so a first production run can be small enough to test a sales channel and still large enough to keep unit cost sensible. Send your target wattage, port mix, plug types and destination market, and you get pricing, lead time and the certification list for those markets within 24 hours.
Frequently asked questions
- Is a GaN charger better than a normal charger? For the same output it is smaller, lighter and runs cooler, and it usually costs a little more. Above 65W the size difference is the main reason to choose GaN.
- Can a 100W GaN charger charge a phone? Yes. USB-C PD negotiates down, so the charger only delivers what the phone requests.
- What is the MOQ for OEM GaN chargers? 200 pcs per model for a first order with custom branding; repeat orders ship faster.
- Do you supply samples? Yes — samples are free for qualified projects, you cover the courier.
