How the 100W Is Shared Between Ports
Many chargers sold as "100W" only reach 100W in total across all ports. Ask any supplier this question. On the MB 100W, either USB-C port gives the full 100W when it charges one device alone:
| Devices plugged in | Power per port | Typical use |
|---|---|---|
| USB-C1 or USB-C2 alone | 100W | One laptop at full speed |
| USB-C1 + USB-C2 | 65W + 30W | Laptop + tablet or phone |
| USB-C1 + USB-A | 65W + 18W | Laptop + phone on a USB-A cable |
| USB-C1 + USB-C2 + USB-A | 65W + 15W shared | Laptop + two small devices |
| USB-C2 + USB-A | 15W shared | Two small devices |
100W needs a 5A (e-marked) USB-C cable. With a normal 3A cable a laptop gets up to 60W.

Is 100W Enough? 65W vs 100W vs 140W
Most brands sell 65W and 100W side by side, and add 140W for 16-inch laptops. This is where each one fits:
| 65W | 100W (MB 100W) | 140W (ZC504) | |
|---|---|---|---|
| Best for | 13 – 14-inch laptops, tablets, phones | Laptop + second device at once; most USB-C laptops at full speed | 16-inch laptops that use PD 3.1 (28V) |
| 16-inch MacBook Pro | Charges slowly | Charges, not at its full speed | Full speed |
| Gaming laptops, workstations | Not suitable | Only USB-C models up to 100W | USB-C models up to 140W |
| Our price per piece | From US$4.92 | US$9.08 – 11.23 | US$16.62 – 17.08 |

What Goes Into a Reliable 100W GaN Charger
Putting 100W into a body smaller than many old 65W bricks is an engineering job, not just a choice of GaN chip. Three things decide whether a 100W charger works well for years:
Power stage
A Yuantuo GaN switch with a Southchip primary controller converts mains power with less loss than silicon, so the charger stays compact at 100W.
Heat
More power means more heat in a small body. A flame-retardant V-0 housing and a 100% aging test under load catch weak units before they ship.
Protocols
A Diansi PD controller handles PD, PPS and QC so phones, tablets and laptops each get the right voltage. Our 25 engineers can adjust the PD profile and firmware for your devices.
| OEM (our MB 100W, your brand) | ODM (new 100W design) | |
|---|---|---|
| What changes | Logo, colour, plug, ports, packaging | Housing, mold, board and firmware |
| MOQ | 500 pcs | 5,000 pcs |
| Certificates | Our existing MB 100W reports | New tests for the new model |
| Timeline | Sample in 3 days, 1,000 pcs in 10 – 15 days | Set per project after our engineers review your brief |
