One plug that charges the laptop at full speed and still has ports left over. A 100w usb c charger is the point at which a single wall socket replaces the pile of bricks under the desk — laptop, phone and tablet from one gallium nitride charger that fits in a coat pocket.
100W is 20V at 5A, and on a 100w usb c charger that is the rating most 13- and 14-inch laptops charge at flat out. A 16-inch machine will charge from it too, just more slowly under full load — which in practice means it holds its charge while you work rather than climbing.
The 100W figure is the single-port maximum, as it is on every multi-port charger ever made. Plug in a second device and the power is shared. Most listings leave that unsaid; here is what actually happens on the two-port version:
On a 100w usb c charger you lose thirteen watts, not half. That is the number worth knowing, and it is better than most chargers in this class manage — a laptop on 87W still charges while you work, and the phone on the other port gets a proper 12W rather than a trickle. The full table is in the specifications.
Older chargers use silicon. Gallium nitride switches faster and wastes less energy as heat, which means a smaller transformer, a smaller case and a part that runs cooler doing the same job.
The practical version: this is a 100w usb c charger roughly the size of the 60W brick your laptop came with, and it replaces a charger, a phone plug and a tablet plug with one thing in the bag. On a desk this usb c wall charger frees two sockets. In a suitcase it is the difference between a packing cube of chargers and one item.
If you are charging one laptop and nothing else, take the two-port 100w usb c charger. If you are the person whose bag has a laptop, a phone and a set of earbuds in it, the three-port version is worth the few dollars — a usb c wall charger you have to unplug something from is a usb c wall charger you end up leaving at home.
A 100w usb c charger is not one speed for everything — it negotiates with whatever is plugged into it and delivers what that device asks for.
At or near full rate: 13- and 14-inch USB-C laptops, most Windows ultrabooks, Chromebooks, and portable monitors. Comfortably: phones, tablets, handheld consoles, earbuds and anything that would otherwise use a 20W or 30W plug — all of which draw far less than the charger can give and are in no danger from the headroom.
Slower than its rating: 16-inch and workstation laptops that ask for 140W or more. They will still charge from a 100w charger, just not at their maximum, and they will usually hold level rather than drain while in use.
A device never draws more than it asks for. A phone on a 100W charger takes its usual 20-something watts and no more — the negotiation runs the other way round from how people assume, which is worth saying because “will it damage my phone” is the most common question about a charger this size. It will not.
This is the part most listings skip, and it undoes more 100w usb c charger purchases than any fault in the charger. 100W here is 20 volts at 5 amps, and 5A needs a cable built for 5A — a USB-C lead with an e-marker chip rated to 5A, not the 3A lead that came with your phone. A 3A cable will work; it will just cap the charger at 60W and give you no warning that it has.
If your laptop charges slowly from a 100w usb c charger, the cable is the first thing to check and the charger is the last. We stock 5A e-marked 100W and 240W leads and will point you at the right one — or tell you the one you already own is fine.

Black or white, same internals either way. This usb c wall charger plugs straight into an Australian socket with no travel adapter and no lead to the wall — the other quiet advantage of a gallium nitride design in a 100w usb c charger is that the whole thing is the plug.

Charges at or near its full rate:
Charges comfortably, well below the limit:
Charges, but not at its own maximum: 16-inch and workstation laptops rated for 140W or more. They will charge and will generally hold level while you work; they will not reach their fastest rate from a 100W supply.
A device only ever draws what it asks for. USB Power Delivery negotiation runs from the device, not the charger, so a phone on this charger takes its usual twenty-odd watts and no more. The headroom is not a risk.
Two things decide whether you see the full 100W.
First, what else is plugged in. On the two-port version the USB-C port gives 20V/5A — the full 100W — on its own, and 87W with the USB-A port also in use, which takes 12W. The USB-A port on its own gives up to 18W. Those figures are in the specifications.
Second, the cable. 100W here means 20 volts at 5 amps, and 5A needs a USB-C lead e-marked for 5A — not the 3A cable that came with a phone, which looks identical and will quietly cap the charger at 60W. Ask us and we will tell you whether the one you own is up to it.
