Why buyers choose multi-port GaN chargers over single-port
A multi-port GaN charger replaces two or three separate adapters with one compact unit. For end users, that means less clutter, fewer outlets used, and one device to pack when travelling. For buyers and resellers, it means a higher ASP, a stronger value proposition, and a product that appeals to laptop-and-phone users — which is everyone.
Higher margin per unit
A 65W 3-port charger costs more than a single-port but less than three separate chargers. The price premium is mostly margin, because the charger uses one power stage, one housing, and one set of certifications.
One charger for every device
Phone, tablet, laptop, earbuds — a 3-port GaN charger covers them all from one outlet. The charger negotiates the right voltage for each device via USB PD.
Travel and desk friendly
GaN technology shrinks a 65W 3-port charger to the size of a legacy 30W adapter. Pack one charger instead of three. For desks, one charger plus one outlet replaces a power strip.

When to choose a 2-port vs a 3-port GaN charger
2-port: phone + one more device
A 2-port charger (USB-C + USB-A, or 2×USB-C) handles a phone plus a tablet, earbuds or a second phone. It is smaller and cheaper per unit. Best for: phone-accessory bundles, travel kits, retail accessories under 45W.
Models: XFC 30W, XFC 35W, CB 45W, CB 65W (all have 2-port options).
3-port: laptop + phone + extra
A 3-port charger (2×USB-C + USB-A) powers a laptop on USB-C1 while charging a phone and earbuds on the other ports. It replaces the laptop adapter entirely. Best for: laptop-accessory brands, Amazon bundle listings, corporate IT.
Models: BK 65W, FB 65W, HK 65W, RJ502, MB 100W, ZC504 140W.
How multi-port GaN chargers split power between devices
Every multi-port charger negotiates power via USB PD. Plug in one device and it gets the full single-port wattage. Add a second or third device and the charger rebalances. The table below shows the typical splits for our 3-port models.
| Model | C1 alone | C1 + C2 or A | C1 + C2 + A |
|---|---|---|---|
| BK / FB 65W | 65W | 45W + 12W | 45W + 15W (split) |
| HK 65W | 65W | 45W + 18W | 45W + 15W (split) |
| RJ502 65W | 65W (cable) | 45W + 18W | 45W + 15W (split) |
| MB 100W | 100W | 65W + 30W / 18W | 65W + 15W (split) |
| ZC504 140W | 140W | 100W + 20W / 18W | 80W + 18W + 18W |
C2 + A splits differ by model. Actual values depend on each device's PD negotiation. The ZC504's display shows the live split in real time.
For 2-port models (CB 45W, CB 65W), the split is simpler: C + A gives 30W + 12W on the 45W or 45W + 12W on the 65W. Two USB-C ports share evenly when both are in use.
