Anker 317 vs Anker Prime 100W: One Port or Three?

The Anker 317 is the sensible pick for one USB-C laptop. It has one 100W USB-C port and includes a 5-foot, 5A USB-C cable. There is no power-sharing table to decode because there is no second port.

Buy the Anker Prime 100W A2688 when the charger needs to serve a laptop, phone, and older USB-A accessory. Its two USB-C ports and one USB-A port are much more useful for a travel kit, but connecting more devices reduces the power available to each one.

This is a research-based comparison. SolderMag has not completed matched charging-speed, thermal, efficiency, drop, or long-term reliability tests on these chargers. The recommendation is based on current Anker documentation, exact US Amazon product identity, included accessories, published output modes, and the jobs each port layout can actually do.

Quick answer

The decision is not really about charging speed. Both can provide up to 100W to one compatible USB-C device. The decision is whether one connection is enough.

Anker 317 vs Anker Prime 100W specifications

Do not call the Anker 317 a two-port charger. It has one USB-C output. That limitation is also its point: the full charger is dedicated to one connected device.

The Anker 317 is a one-device charger

The 317 makes sense when a laptop is the only device that needs wall power. Anker documents standard fixed USB-C profiles up to 20V/5A and PPS up to 3.3–21V/5A, with a 100W maximum.

The included cable matters. Full 100W USB-C charging needs a suitable 5A, e-marked cable; an ordinary 3A cable commonly limits the connection to 60W. Anker says the 317 bundle includes a 5-foot cable rated for the charger's maximum output, so a buyer does not need to solve that part separately.

One port also removes a common source of confusion. Adding a phone cannot cut the laptop's allocation from 100W to 65W, because there is nowhere to connect the phone. You either carry another charger or accept that devices will charge one at a time.

That is a good trade for a person replacing one bulky laptop brick. It is a poor trade for a traveller who expects one wall outlet to cover an entire bag.

The Prime 100W is a small multi-device charger

The Prime A2688 uses two USB-C ports and one USB-A port. Either USB-C port can reach 100W when it is the only connection. The useful difference appears when another cable is plugged in.

Anker documents 65W + 35W across the two USB-C ports. That is a practical split for a 45W-to-65W laptop plus a phone, tablet, handheld, or power bank. It is not a two-laptop performance setup: the second 35W share may be too low for a demanding computer under load.

With USB-C1 and USB-A occupied, the published split is 65W + 22.5W. USB-C2 plus USB-A is a much weaker 12W + 12W mode, so port order matters. Using all three outputs brings the total ceiling to 89W, not 100W.

Those limits do not make the Prime misleading. They make the allocation table required reading. Buy it when 65W for the main laptop remains enough after the phone is connected.

Which is better for a MacBook?

For a MacBook Air or a 13-inch or 14-inch MacBook Pro, either charger may provide more than the computer can use in ordinary charging. The deciding factor is the rest of the kit.

Choose the 317 when the MacBook is the only device connected to the outlet. Choose the Prime if you also charge an iPhone, iPad, watch puck, earbuds, or power bank and are comfortable with the published multi-port split.

For a compatible 16-inch MacBook Pro, neither charger provides the 140W USB-PD 3.1 fast-charge path. A 100W charger can still be useful for travel, lighter work, or overnight charging, but it cannot produce 140W. Our Anker Prime 160W vs 100W comparison covers the higher-output option and cable requirements.

Which is better for Windows laptops?

Start with the laptop's own requirements. A USB-C port does not guarantee that the computer accepts 100W USB Power Delivery, and some workstation or gaming laptops still need a proprietary adapter for full performance.

The 317 is cleaner for a laptop that accepts up to 100W and does not need another device charged at the same time. The Prime is better for a 45W-to-65W work laptop because its 65W multi-port allocation can leave useful power for a phone.

Do not assume that a 100W source replaces a 130W, 140W, 180W, or 240W laptop adapter under load. Check the manufacturer's input specification. A lower-power USB-C charger may charge slowly, maintain the battery during light work, or fail to keep up with a heavy workload.

Our USB-C charger wattage guide explains how to match a device, charger, cable, and multi-port allocation without buying by the largest number on the box.

Cable and bundle differences

The 317's included 5A cable is part of its value. It gives a buyer a documented route to the 100W profile without adding another purchase.

Anker's standard Prime A2688 product page says charging cables are not included. If you already have a suitable e-marked cable, that may not matter. If you do not, include the cable in the total purchase decision.

Retail bundles change. Check the exact listing rather than assuming that every 317 or Prime package contains the same accessories. A cable shown in a photo is not proof that it is in the selected variant.

For charging-only use, cable power rating matters more than data speed. Our USB-C cable guide separates 60W, 100W, and 240W power support from USB4 data requirements.

Who should buy the Anker 317?

Buy the 317 if:

• one USB-C laptop is the whole charging job;
• you want the appropriate 5A cable in the documented bundle;
• you prefer one uncomplicated output over a power-sharing table;
• you can charge a phone later or from another source;
• the 317 is meaningfully cheaper when you shop.

Skip it if you regularly have to choose between charging the laptop and charging the phone. One port is not a small inconvenience when the wall outlet is behind a hotel desk.

Who should buy the Prime 100W?

Buy the Prime A2688 if:

• one charger needs to replace two or three smaller bricks;
• a 65W laptop allocation remains adequate while another device charges;
• you still use a USB-A cable or watch puck;
• you already own suitable USB-C cables;
• the extra ports are worth more than the 317's included cable.

Skip it if every connected device needs a large share at the same time. One 100W label does not turn three ports into three independent chargers.

Who should skip both?

Skip both if your laptop needs only 45W or 65W and bag size matters more than headroom. A smaller reputable charger may do the same job with less bulk.

Skip both if you need 140W fast charging. Move to a compatible USB-PD 3.1 charger and an EPR cable rated for the intended output.

Skip both for a permanent four-device desk setup. A corded 200W multiport charger is easier to position and provides more shared power.

Skip both if your laptop does not accept USB-C charging. No adapter cable can make an unsupported USB-C port become a power input.

Alternatives

Anker Prime 160W A2687: choose this when 140W standard laptop output or two useful laptop connections justify more shared power. It replaces a different class of charger, not just a faster 317.

UGREEN Nexode 100W 4-Port: consider this when four ports matter more than the Anker Prime's smaller 2C1A layout. Read our Anker Prime 100W vs UGREEN Nexode comparison and check the exact allocation for the devices you will connect.

Satechi 100W USB-C PD Compact GaN: a corded desktop alternative with two USB-C ports and USB-A. Its cable-to-wall form is easier to place on some desks but less convenient than a folding wall charger for a small travel kit.

A reputable 65W charger: enough for many ultrabooks, tablets, phones, and handhelds. Do not buy 100W capacity that no device can use.

Frequently asked questions

Does the Anker 317 have two ports?

No. The Anker 317 A2672 has one USB-C output. It can deliver up to 100W to one compatible device with a suitable cable.

Is the Anker 317 a GaN charger?

Anker's current 317 product and support pages do not make GaN the product's defining documented feature, so we would not buy or describe it on that assumption. Its practical advantages are one 100W USB-C port, a folding US plug, and an included 5A cable.

Can the Anker Prime 100W give 100W while a phone is connected?

Not under Anker's published two-port allocations. Two USB-C devices receive 65W + 35W. USB-C1 plus USB-A receives 65W + 22.5W. Disconnect the second device when the laptop needs the full 100W profile.

Does the Anker 317 include a 100W cable?

Anker documents a 5-foot / 1.5-metre USB-C cable capable of 5A and 100W in the bundle. Confirm the contents of the exact retailer variant before ordering.

Can either charger fast-charge a 16-inch MacBook Pro at 140W?

No. Both top out at 100W from one USB-C port. Use a compatible 140W USB-PD 3.1 charger and cable if that fast-charge path matters.

Is the Prime 100W always the better value?

No. Extra ports are wasted if you only charge one laptop. The 317 can be the better complete purchase because its documented bundle includes the required high-current cable.

Final recommendation

Buy the Anker 317 when the job is one USB-C laptop. It is the cleaner choice, and the included 5A cable removes one easy buying mistake.

Buy the Anker Prime 100W A2688 when one outlet needs to cover a laptop, phone, and accessory. Its extra ports justify the upgrade only if the 65W + 35W or 65W + 22.5W allocations fit your devices.
