The job: turning house current into the protocol your phone speaks.
A wall charger has one job and it is not "making electricity faster". It converts house current into a low voltage, then negotiates with the phone about how much of it to hand over. The negotiation is the part the box never explains, and it is the part that decides everything.
That is why the wattage printed on a block is only half a sentence. Twenty watts on a single-port block is twenty watts for the one thing plugged into it. Sixty watts across five ports is sixty watts for all five together, divided by rules the manufacturer usually does not publish.
The blocks below are sorted by how directly they answer that question. A charger that states a figure for a specific port has told you something. A charger that states a total and stops has told you the size of a pie, not the size of your slice.

How to choose one
What to weigh
What to look for
Why it matters
Port count
How many ports, and whether the listing names a figure for any single one
One port means the stated wattage is undivided. Five ports means the stated wattage is a total and the split is usually unpublished.
Named protocol
PD, PPS, or Quick Charge written out rather than just a wattage
A protocol name tells you the charger negotiates. A bare wattage tells you what the transformer can do, not what your phone will be offered.
Cable included
Whether a cable ships in the box, and what length
A capable charger with a limited cable behaves like a limited charger. Outlet placement decides length more often than anything else.
Physical shape
Folding pins, thickness, whether it blocks the second outlet
A block that covers the adjacent socket costs you an outlet, which is a real cost in a hotel room with two of them.
GaN or not
Whether the listing states GaN construction
GaN is about size and heat, not extra speed. It is why a high-wattage block can be small, not why it is fast.
20W single-port
One port, one number, nothing to divide. Whatever the block is rated for is offered to the single thing plugged into it.

Two blocks, two cables
Anker 20W USB-C Charger Block, 2-pack
20W single-port
Two 20W USB-C blocks with cables, which is the least interesting and most useful thing in this category. One port means the stated figure is not being divided between sockets, which is the only thing a wattage on a box can honestly tell you. Two of them means one lives by the bed and one lives somewhere else.

A 20W PD block with a six foot cable, which is the length most people actually need and rarely get in the box. PD is named in the listing, which means the block is stated to negotiate rather than just push five volts. One port, so the number is not shared.

The same 20W idea with a ten foot cable instead of six. Ten feet is the length that turns an awkward outlet into a non-issue, and it is the only meaningful difference between this and the shorter version. Long cables lose a little voltage over the run, which matters more at high wattage than at twenty watts.
Two 20W blocks paired with USB-C to Lightning cables at six and ten feet. This is a set for a Lightning phone, which means an iPhone 14 or older, and it is worth knowing that before it arrives. The two different cable lengths in one box is the unusual part.

Anker Nano 45W Smart Display Charger
Multi-port and high wattage
A single-port GaN block with a small readout on the face. Because the listing states one USB-C port, the 45W figure is not a budget being divided between sockets, which is the whole reason this page keeps repeating the phrase "port budget" everywhere else. No cable is included, so the cable you already own decides what actually happens.

Twenty-five watts is the figure that shows up in Samsung documentation for its faster charging mode, and this listing states that number directly.

Four blocks, each with a USB-C port stated at PD 20W and a USB-A port stated at QC 3.0. This is the first listing in the category where the phrase "per block" matters, because two ports on one block share whatever the block can actually deliver.

Questions that come up at the counter
Does a 60W five-port charger give my phone 60W?
No. Sixty watts is the budget for the entire block with everything plugged in. Your phone gets whatever the block allocates it after the split, and most listings do not publish how that split works.
Is a bigger charger bad for my phone?
A phone asks for what it wants through the charging protocol and takes no more than that. A charger rated higher than the phone needs is not forced onto it. What a bigger charger buys you is headroom, not risk.
Why is my new fast charger slow?
Three usual suspects, in order: the cable, the protocol, and the temperature. A cable without the right rating will cap the whole chain. A charger and a phone that do not share a protocol fall back to something slow. And a warm phone deliberately slows its own charging.
Do I need a 45W charger for a phone?
Usually the reason is not the phone. A phone negotiates for what it wants and takes no more, so any headroom above that simply sits unused. What a 45W block buys you is one charger that also covers a tablet or a laptop.
What does "GaN" change about a wall charger?
Gallium nitride switches more efficiently than silicon, which means less waste heat and a smaller body for the same output. It does not add speed on its own.
