Anker 737 Power Bank (PowerCore 24K)

The Anker 737 Power Bank (PowerCore 24K), model A1289, is a USB-C power bank built for laptop-class charging on the move:

• 86.4 Wh capacity — under the 100 Wh threshold that international airline rules use to gate carry-on lithium batteries. Permitted in carry-on luggage on virtually every major carrier without prior approval.
• 140 W single-port USB-C output, enough to charge a 16-inch MacBook Pro at full speed, or to fast-charge any current laptop / phone / tablet at the device’s maximum supported rate.
• 140 W input via USB-C, so the bank recharges from empty in roughly an hour and a half with a compatible 140 W charger.
• A built-in smart digital display that shows live input wattage, output wattage, remaining capacity, total lifetime input/output, and battery cycle / health metrics. No app, no Bluetooth, no pairing — the data is on the device itself.

• Air travel. 86.4 Wh is well under the 100 Wh airline threshold and the bank is permitted in carry-on without pre-approval. For multi-day travel where you want a single backup that can keep a laptop topped up across a workday, this covers it.
• Mobile work / coworking. 140 W single-port output drives a 16-inch MacBook Pro at full speed and reaches the max supported charge rate of any current USB-PD device. Good fit for someone who works out of cafes, hotels, or rental desks where outlet access is unreliable.
• No-frills buyers. The smart display is on the device itself — there’s no app to install, no account to make, no Bluetooth pairing to manage. For buyers who want hard data without the connected-app overhead, the 737 reads out everything important on its own screen.

• Whole-cottage or RV power. This is a USB power bank, not a portable power station — no AC outlets, no inverter, no solar input. For AC-load use, look at the Portable Power Stations category.
• Long off-grid trips. 86.4 Wh is sized for individual-device topping-up, not multi-day off-grid runtime. A laptop can drain it in roughly 45 minutes at sustained full draw.
• Remote monitoring. If you want to track per-port stats from a phone, find the bank via a sound alert when misplaced, or share data across multiple devices, this model has no app or Bluetooth — the data lives on the unit’s screen only.
• No NRTL safety mark published. Anker’s Canadian product page does not list specific NRTL safety marks (CSA, cULus, cETL) for this model. USB power banks of this class typically certify under different regimes — FCC / IC where any radio is present (this model has none), UN38.3 for lithium shipping safety, airline-carry rules for the 100 Wh threshold — none of which are stated explicitly on the Canadian product page. If certification documentation matters to your purchase (corporate procurement, airline confirmation, insurance), request the declaration of conformity from Anker before buying.

• Sub-100 Wh by design. The 86.4 Wh sizing intentionally stays inside the global airline default rule. Banks pushing above 100 Wh often require airline pre-approval and are technically prohibited on some carriers.
• Heavier than typical phone-only banks. At 630 g this is closer to a slim hardcover book than to a phone-sized accessory. The weight is driven by the laptop-class capacity and the 140 W inverter; not avoidable at this output level.
• Display does enough. The on-device display covers monitoring needs that other banks in this class only expose via an app — useful when you want a quick read on remaining capacity or the actual draw a device is pulling.
• Pass-through behavior. With a charger and a device both plugged in, the 737 routes input directly to the output port while topping up its own cells in parallel. Good for desk-charging where the bank is also acting as a power-source hub.
