For a 65W-class laptop and a simpler cable kit
The built-in cable itself is specified up to 65W, alongside a separate USB-C port and USB-A. That creates several charging options without carrying a separate USB-C cable for the integrated path.

Our verdict
A practical middle ground for a laptop that accepts up to 65W USB-C input: integrated cable convenience, a 20,000mAh label and a sub-500g listed weight. It is not the pick for a device that needs more than 65W from one port.

Tradeoffs
The built-in cable is fixed to the bank
The integrated USB-C cable can reduce loose accessories, but it is part of the power bank rather than a separate cable that can be swapped independently. The separate USB-C port remains available.
Anker’s Canada page contains an inconsistent capacity row
The US product page and the A1383 US support record identify the 20,000mAh model; the support record also supplies the 65W port details. Anker’s Canada page has a conflicting 10,000mAh specification-panel row for the same A1383 listing, which we exclude rather than merge into this US dossier.

Before connecting devices
Ports and charging behavior
A port’s published maximum and the combined multi-port limit are separate ratings. A device can draw less than the bank’s maximum based on its own requirements and the negotiated charging profile.
One USB-C path: up to 65W
Anker’s A1383 support record specifies up to 65W for the built-in cable and USB-C port. Its 87W total rating is the combined output ceiling across the bank’s ports.

Exact-model questions
Frequently asked questions
Why do we list 20,000mAh when a Canada page shows 10,000mAh?
The US product listing and model-specific A1383 support record identify a 20,000mAh unit. A Canada product page for A1383 repeats 20K in its description but shows 10K in a separate spec row. We follow the matching US product and support documentation and keep the contradictory Canada row out of the metric.

Does the bank deliver 87W to one laptop?
No. Anker rates one USB-C path at up to 65W. The 87W figure is the total output across ports.
