China makes most of the world’s GaN chargers, and Shenzhen makes most of China’s. This list is written by WECENT, a GaN charger manufacturer in Shenzhen, for brands and wholesalers who want to source the current generation of GaN fast chargers factory-direct. Each pick is a wattage class worth OEM-ing in 2026, with the specs that matter and the questions to ask a factory.
What “GaN3” means (and the gan2 vs gan3 question)
“GaN2” and “GaN3” are the industry’s shorthand for generations of gallium-nitride power ICs. Second-generation (GaN2) parts integrated the driver and half-bridge into one chip; third-generation (GaN3) parts push switching frequency and integration further, which is what lets a 100W charger shrink to pocket size while staying cool. Brands use the labels loosely, so what actually matters is measurable: switching frequency, power-stage integration, and efficiency under load. Ask a factory for the GaN part number and the efficiency data — not just the sticker.
The 2026 picks to OEM (by wattage class)
1. 65W GaN3 USB-C — the mainstream workhorse
The most-sold class in the industry: one compact brick that fast-charges a phone and charges an ultrabook. Perfect as the first OEM SKU — see the 65W GaN charger with EU/US/UK/AU plugs for a ready platform.
2. 100W GaN3 multi-port — the laptop + device best
Two laptops, or a laptop plus a dock and a phone. This is the power-user segment with the best margin — see the 100W OEM charger platform.
3. 140W GaN3 PD 3.1 — the Pro-laptop best
The first EPR class (28V/5A = 140W) for Pro laptops and workstations. Two options worth OEM-ing: the 140W 2A3C GaN charger for value, and the WEX140S smart-screen 140W as a premium flagship that photographs well.
4. 240W GaN3 desktop — the workstation best
For desks that run a laptop, a dock, a monitor and phones from one unit. The top of the OEM range — see the 240W GaN charger platform.
5. 45W GaN3 travel — the multi-market best
The smallest laptop-class charger, with foldable or interchangeable plugs for global markets — see the 45W travel charger and the wider travel charger category.

How to verify a real GaN3 design (before you order)
- Ask for the GaN part number — a genuine third-generation design uses an integrated GaN power stage, not silicon with a GaN sticker.
- Ask for efficiency data at 25%, 50% and 100% load.
- Ask for board photos — compact transformer, minimal heatsink.
- Check the certification report lists your exact output profiles, including PD 3.1/EPR for 140W+.

FAQ
What is a GaN3 charger? A charger built on third-generation gallium-nitride power ICs — higher switching frequency and integration than earlier generations, which means smaller and cooler designs at the same wattage.
Is GaN2 or GaN3 better? For buyers the practical difference is size, efficiency and price. Verify with part numbers and efficiency data rather than the generation label.
Do GaN3 chargers need different certification? No — the safety and EMC testing is product-level. Certification reports must match your exact output profiles, including EPR for 140W+.
Can you make a 240W GaN3 charger? Yes — 240W platforms are available with MOQ from 200 pcs.
What is the lead time for an OEM GaN3 order? Samples typically 1-3 weeks after spec freeze; production 1-3 weeks depending on quantity — see the services page.
