Anker Prime 100W review: three ports, one shared power budget

Start with the devices you charge together

A charger earns its place by covering a real routine. Before choosing the Prime 100W, write down what will be connected at the same time: perhaps a laptop during work, a phone beside it and an older accessory with a USB-A cable. This is a different question from asking whether one device can briefly take the charger's headline output.

The A2688 offers a higher output ceiling than the 65W chargers already covered on WoodsPick. That creates a reason to consider it when a compatible laptop can use more power or when several devices need connections. It does not automatically create a reason to replace a charger that already meets your needs.

Check your laptop's own USB-C charging requirements first. A higher-wattage adapter cannot make a device accept power beyond its supported input, and a laptop's needs can change with its workload. The practical target is a suitable charging combination, rather than the largest number printed on the box.

Read the shared-output limits before counting the ports

Anker lists up to 100W for either USB-C port used alone, up to 100W combined with two ports occupied, and up to 89W combined with three. USB-A reaches up to 22.5W on its own. Those are different operating conditions, not simultaneous guarantees.

The important implication is simple: the laptop does not keep a reserved 100W while the other devices get extra power. With multiple connections, everything must fit inside the shared ceiling. A phone and a laptop also do not necessarily divide that ceiling equally.

Anker advises using the upper USB-C port for the laptop when both USB-C ports are connected. Follow the exact allocation diagram for your combination instead of borrowing a split from another Prime model. A familiar brand name and three similar-looking sockets do not establish identical behavior across a product range.

If maintaining a particular laptop input is essential, confirm the port allocation before ordering. A combined maximum alone cannot answer that question. There is little value in replacing a reliable setup with a tidier one that does not support the workload you actually run.

The cable is part of the purchase decision

Charging cables are not included. Anker recommends an E-Marker cable for optimal 100W charging, so the cable already in your drawer needs checking rather than assuming. Match the device connector, the required charging capability and a length that reaches your normal seat or desk position.

Think about the entire kit when comparing the price. Someone with an appropriate USB-C cable is buying an adapter. Someone starting from scratch is buying an adapter plus one or more cables. Those are different totals, even when both shoppers see the same charger listing.

USB-A remains useful if it avoids replacing a working accessory cable. For a mostly USB-C setup, the second USB-C connection may matter more. Count the cables you actually use; a port you never connect adds less practical value than a specification table suggests.

When 65W is still enough

The single-port Anker 715 65W keeps the decision straightforward if one compatible device is all you need to connect. It offers no simultaneous second connection. The UGREEN Nexode Air 65W is another single-port option, with an included cable in the version covered here.

Neither becomes unsuitable simply because a 100W product exists. If your device requires no more than their available output and you charge separately, the larger power budget may not solve a problem for you.

The Prime 67W is a more direct connection-count comparison because it also mixes USB-C and USB-A. Its documented two-port ceiling is 65W combined. The A2688's higher shared ceiling is the useful distinction to investigate, without assuming how much any individual connected device will receive. Our 65W versus 100W guide explains how to start that calculation.

Check the physical setup, too

Anker publishes a weight of 6 oz and dimensions of 1.7 by 1.1 by 2.7 inches, excluding the prongs. Use those measurements to plan the space beside a crowded outlet or inside an accessory pouch. They do not tell you whether a particular loose hotel socket will hold it securely.

The listed input is 100–240V, 50–60Hz. For travel, match both the electrical input and the physical plug to the destination. A charger with a suitable voltage range can still need a plug adapter. The travel charger checklist covers the rest of that preparation.

The buying decision

Choose the A2688 if your compatible devices can use its power budget and the port mix replaces a real inconvenience. Keep a suitable 65W charger if one connection already covers your routine. For a laptop that needs a guaranteed allocation alongside other devices, resolve the exact split first.

Check the current Anker Prime 100W offer on Amazon, matching model A2688, the US plug and the contents of the selected bundle. Compare the full cost of any cables you need rather than treating the adapter price as the complete setup.
