People buy a 100W charger and keep the cable from their old phone, then conclude the charger is slow. The cable is the part of the chain that decides whether 100W ever reaches the device, and it is the part with the least printed on it.
100W is 5 amps, and 5 amps needs a chip
USB-C Power Delivery reaches 100W in one specific way: 20 volts at 5 amps. Every other combination in the standard tops out lower, and 5A is the number that matters, because a standard USB-C cable is only rated to carry 3A — about 60W. Above that, the cable must contain an E-Marker chip: a tiny IC in the connector that tells the charger “this cable can take 5 amps, go ahead”.
No E-Marker, no 100W, regardless of what the charger can do. This is why a 100W charger with a 60W cable behaves exactly like a 60W charger, and why “it works with my laptop” is not evidence of anything — a laptop will charge at whatever it is given.
The second variable is heat. Five amps through a thin conductor is resistive loss, and loss is heat at the connector. Short, thick, certified cables run cooler; long thin ones get warm at the plug, which is the physical reason cheap high-watt cables fail at the ends rather than in the middle.
| Anker 100W USB-C | UGREEN 100W USB-C | Baseus 100W USB-C | |
|---|---|---|---|
| Rated power | 100 W | 100 W | 100 W |
| Current at 20 V | 5 A | 5 A | 5 A |
| E-Marker chip | Required and present for 5A | Required and present for 5A | Required and present for 5A |
| Data speed | USB 2.0 on most charging cables | USB 2.0 on most charging cables | USB 2.0 on most charging cables |
| Length options | Multiple | Multiple | Multiple |
| Price | See button | See button | See button |
All three of these are rated for the same electrical job, so the differences that matter are mechanical: how the strain relief is built, how the braid survives being coiled around a bag, and whether the length you need is available at 5A rather than only at 3A.
1. Anker 100W USB-C: the one to buy if you want it to survive
Rated 100W, 5A, with the E-Marker in place, in the braided construction Anker has been building for years. The argument for it is not speed — all three here hit the same 100W — it is the joint where the cable meets the connector, which is where cheap cables die after six months of being stuffed into a bag.
Buy it if the cable lives in a backpack. Skip it if it will sit permanently on a desk; a fixed cable never sees the abuse that breaks them.

2. UGREEN 100W USB-C: the value option
Same electrical spec — 100W, 5A, E-Marker — usually a bit less money. UGREEN’s cable range is wide enough that you can get the exact length you want at 5A rather than settling for a 3A version because it was the only one in stock.
The thing to check on any UGREEN cable is the model number rather than the line name: they sell both 60W and 100W cables that look nearly identical.
Buy it if you want 100W without paying for the braid. Skip it if you need the cable to survive daily bag duty.

3. Baseus 100W USB-C: the one that shows the watts
Baseus sells 100W cables with a small wattage display in the connector, which answers the question this whole article is about: whether the cable is actually passing 100W to the device or has fallen back to 60. It is a diagnostic tool disguised as a cable.
Whether that display survives a year of daily coiling is the open question — it is another component in the place where cables break.
Buy it if you troubleshoot charging and want to see the negotiation. Skip it if you want the simplest possible cable.

The short version
Any of the three will carry 100W if — and only if — it is the 5A version with an E-Marker. Buy the shortest cable that reaches from the outlet to where you sit, because length is resistance, and buy the one with the best strain relief if it travels. If your 100W charger feels slow, check the cable before you blame the charger: a 3A cable turns every 100W brick into a 60W one.
