USB-C was meant to make cables simple: one shape for everything. Instead, it hid the differences inside identical-looking plugs. The same port might charge a laptop at full speed, charge it slowly, drive two monitors, or do none of those things. Once you know a handful of terms, the confusion mostly goes away.
Charging terms
- USB Power Delivery USB PD
- The standard that lets a charger and a device agree on how much power to send. A PD charger only delivers high wattage when the device asks for it, so a big laptop charger is safe for a phone — the phone simply draws less.
- Watts (W)
- Power. Phones typically charge at well under 50W; thin laptops often want 45–65W; larger laptops 90–140W or more. A charger below your laptop's rating will usually still charge it, just slower, and may not keep up under heavy use.
- Total vs per-port wattage
- A multi-port charger's headline number is the total. Plug in a second device and the power is split, often unevenly. Check the per-port figures to know what your laptop gets when your phone is plugged in too.
- GaN gallium nitride
- A semiconductor material that handles power more efficiently than traditional silicon, so GaN chargers can be smaller and run cooler at the same wattage. It's about size and heat, not about charging your device faster than PD allows.
- PPS
- Programmable Power Supply, part of USB PD. Some phones use it for their fastest charging mode, so a charger without PPS may charge them a little slower.
Cable terms
- 60W vs 240W cables
- Most USB-C cables carry up to 60W. Higher power needs a cable with an e-marker chip rated for it (100W, or 240W under the newer extended power range). A thin "charging" cable can be the bottleneck for a laptop.
- Data speed
- Cables differ in data speed too — from slow USB 2.0 to 40Gbps or more. A charging cable that came with a phone is often USB 2.0 speed, which is fine for power but not for a fast external drive or a monitor.
Hub and dock terms
- USB-C hub
- A small adapter that adds ports — USB-A, HDMI, SD card, Ethernet — usually powered by the laptop. Good for travel and light desk use.
- Docking station
- A larger, usually mains-powered unit that charges the laptop and runs monitors and peripherals through one cable. Better for a permanent desk.
- Pass-through charging
- A hub port that accepts your charger and passes power to the laptop. The hub keeps some for itself, so a 100W charger may deliver noticeably less to the laptop.
- DisplayPort Alt Mode
- How a USB-C port sends video. Your laptop's port must support it for a hub's HDMI or DisplayPort to work at all.
- Thunderbolt 4 / USB4
- High-bandwidth standards (40Gbps) that can run multiple high-resolution monitors and fast storage through one cable. Thunderbolt docks need a Thunderbolt or compatible USB4 port on the laptop to use their full capability.
- MST vs single display
- Multi-Stream Transport lets one video signal drive several monitors. Some laptops, notably many Macs with base chips, only support a limited number of external displays no matter what the dock offers. Check your laptop's display limit first.
Quick matching guide
| You want to… | Look for |
|---|---|
| Charge a phone fast | USB PD charger, ideally with PPS for some Android phones |
| Charge a laptop and phone from one brick | Multi-port GaN charger with enough per-port watts for the laptop |
| Add ports on the go | Compact USB-C hub with pass-through charging |
| One-cable desk with monitors | Powered dock; Thunderbolt 4 if your laptop supports it |
Where Mokin fits
Mokin's desk range covers exactly these categories: USB-C hubs, docking stations, and GaN chargers from 67W up to 200W, built for Windows, Mac and Thunderbolt 4 setups. The brand also sells portable power gear for off-grid use — a 288Wh/300W portable power station and foldable IP68 solar panels rated up to 120W. It lists a 12-month warranty and a 30-day money-back guarantee. The terms above are what to check against any listing: total versus per-port watts on a charger, and video and display support on a hub or dock.
Conclusion
For chargers, think in watts per port and make sure it's USB PD; GaN gets you the same power in a smaller, cooler brick. For cables, check both power and data ratings. For hubs and docks, start with what your laptop's port supports — video, Thunderbolt, and how many displays — because no accessory can add what the port can't do.
