The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Anker 737 is the longest-tenured 140W laptop power bank in this candidate pool and is repeatedly cited as a default recommendation in r/anker, r/buildapcsales, and r/bapcsalescanada. A bapcsalescanada commenter who has owned it for two years calls it 'awesome,' and a buildapcsales thread confirms PD 3.1 140W charging on M1/M2 16-inch MacBook Pros. techradar's review specifically calls out the color display showing remaining capacity, battery health, and live power output as a standout feature.
What reviewers liked
- 140W PD 3.1 output confirmed by buildapcsales testers on 16-inch MacBook Pros
- Color display showing live wattage and battery health praised across techradar and r/bapcsalescanada
- Multi-year reliability reports across r/anker and r/buildapcsales
- Largest review base in the pool (17,001 Amazon reviews) at a solid 4.4 average
Where it falls short
- An r/anker review measured roughly 57% efficiency at high loads
- Only laptops that support PD 3.1 can actually negotiate the full 140W
- Form factor is bulkier than newer Prime-series alternatives
- Some r/bapcsalescanada users report needing to exchange early units, suggesting some QC variance
Across the reviewers we read, the Anker 737 is the longest-tenured 140W laptop power bank in this candidate pool and is repeatedly cited as a default recommendation in r/anker, r/buildapcsales, and r/bapcsalescanada.

The honest counterweight is an r/anker post titled bluntly 'Anker 737 power bank is garbage' that measured roughly 57% efficiency in their testing. That's an outlier in the broader sentiment but a real datapoint, and other community threads acknowledge that efficiency at peak 140W draw is not flattering. Reviewers also note that to actually hit 140W output, your laptop needs to negotiate PD 3.1, which not every machine supports.
For someone who specifically wants 140W output, a robust track record, and the most-discussed power bank in laptop-charging conversations, the cross-source consensus still lands here. The newer Anker Prime 220W/300W models are technically more capable, but the 737 has years of real-world durability reports backing it.

I've used this for two years and it's awesome. The best feature is the displayed wattage for me, helps to figure out what cords are slow, ...
Received the device yesterday and was able to test it twice now. First of all, efficiency around 57% is an absolute JOKE.
