BatteryRank review
A fit for a USB-C laptop that can use the documented 140W profile, especially when a 24,000mAh label matters more than a lighter pocket kit. The 140W rating is the per-port ceiling, not extra power available on top of a second 140W port.
Ratings below are manufacturer-claimed. Open a reading to see its source and check date; derived comparisons are identified separately.
Use and carrying fit
Anker documents 140W USB-C output on each C port and a third USB-A output. Confirm the laptop accepts USB-C Power Delivery at the intended rate; the port rating alone does not establish compatibility with every laptop.
What changes the choice
Anker’s current US product page lists 630g, the A1289 model-specific support record lists 607g, and a regional introduction lists 632g. We use the current US listing for the US catalog metric and retain the unresolved disagreement; confirm the exact retail unit if pack weight is decisive.
Each USB-C port is specified up to 140W, while the published total output is also 140W. Attaching a second device does not create another independent 140W budget.
Before connecting devices
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.
The model-specific input profiles reach 28V⎓5A on USB-C. Reaching that ceiling requires compatible charging equipment and a 5A-rated cable; Anker lists the input profile rather than promising every charger will deliver it.

Manufacturer claims link to the dated source used for this exact revision. Watt-hours appear only when the OEM states them explicitly; we do not infer energy from milliamp-hours.
Exact-model questions
Yes. Anker’s A1289 support specification lists a 28V⎓5A USB-C output profile, or 140W, for each USB-C port.
The current US product page lists 630g, the exact-model support record 607g, and a regional introduction 632g. We use the current US listing’s 630g for this US catalog and show the unresolved discrepancy; the sources do not establish a separate hardware revision that explains it.
