Anker 737 Power Bank (PowerCore 24K, 24,000mAh, 140W): short answer
The Anker 737 (PowerCore 24K, model A1289011) measures 155.7 × 54.6 × 49.5 mm and weighs 630 g. That relatively large size and weight are a deliberate trade‑off to provide 24,000 mAh capacity and up to 140W USB‑C charging: it’s less pocketable than compact banks but better suited to users who need high‑watt laptop charging and a higher usable energy reservoir.
- Official dimensions: 155.7 × 54.6 × 49.5 mm; official weight: 630 g.
- The extra mass and volume reflect the 24,000 mAh capacity and circuitry required for sustained high‑watt (up to 140W) USB‑C charging.
- Independent testing reports usable energy around ~73–77 Wh, underscoring that the larger form factor yields meaningful runtime for laptops and multiple devices.
- It’s not pocketable for everyday carry; better considered as a bag‑carried unit for professionals or travellers who prioritise laptop charging power.
- The retail package does not include a PD 3.1 cable or AC charger, so achieving the top 140W spec requires buying compatible accessories separately.

What the verified specs say about size and weight
Anker’s official product documentation lists the 737’s physical dimensions as 155.7 × 54.6 × 49.5 mm and the product weight as 630 g. These measurements sit alongside the stated 24,000 mAh capacity and features such as a Smart Digital Display and two‑way charging. Those published figures are the baseline for assessing portability.
What independent evidence adds about real‑world impact
Professional reviews and lab measurements confirm that the 737’s larger size and mass translate into useful real‑world benefits. Independent testing reported usable energy in the vicinity of ~73–77 Wh after conversion losses, which corresponds to longer runtimes for phones and notably more usable charge for laptops than smaller, pocketable banks. Reviewers also measured fast recharge behaviour and sustained high output, which require the denser internal battery and heavier power electronics that contribute to the unit’s weight.
Practical trade‑offs: portability versus 140W performance
The 630 g weight and mid‑sized footprint are the trade‑off for delivering laptop‑class charging (manufacturer rating up to 140W when used with PD 3.1 cable/device). If your priority is minimal everyday carry or pocketability, the 737 is heavier and bulkier than compact daily power banks. Conversely, if you need high sustained output and a higher usable energy reserve to recharge laptops or multiple devices between charges, the additional mass and volume are the reason the unit can provide that performance.
Carrying, storage and accessory considerations
Because of its size and weight, plan to carry the 737 in a bag rather than a pocket. The retail package does not include a PD 3.1 cable or AC charger; Anker’s guidance and reviewer notes make clear that a PD 3.1–capable cable and a compatible charger (if you want the fastest recharge rates) are separate purchases. Also note that some early review units were cited as lacking a 12V PD option present in other PD profiles—compatibility with specific legacy devices can vary, so check device voltage requirements if you depend on particular PD voltages.
Buyer takeaway: how to decide based on size and weight
Choose the Anker 737 if you regularly need laptop‑grade, high‑watt USB‑C charging on the go and are willing to accept a heavier, bag‑carried power bank in exchange for higher usable energy and fast recharge. If ultra‑light, pocketable carry or bundled PD 3.1 accessories are your top priorities, this unit’s 155.7 × 54.6 × 49.5 mm size and 630 g weight make it a less suitable choice unless you’re prepared to add cables and accept the extra mass.
Bottom line on Anker 737 Power Bank (PowerCore 24K, 24,000mAh, 140W)
Official dimensions: 155.7 × 54.6 × 49.5 mm; official weight: 630 g.
