The Verdict
The Anker 737 Power Bank is a formidable piece of hardware that largely justifies its viral status among tech enthusiasts and travelers. It delivers on its core promise: charging high-demand devices like MacBooks and the Steam Deck nearly as fast as a wall outlet. With a massive 24,000mAh capacity and a genuinely useful smart display, it's a workhorse for anyone who needs serious power away from an outlet. However, its significant weight and bulk mean it's strictly a backpack accessory, not a pocket companion. While isolated reports of long-term reliability issues exist, the overwhelming user consensus points to a powerful and dependable, if hefty, charging solution.
What Went Viral
The Anker 737 Power Bank blew up on TikTok for three key reasons. First, its massive 140W max output is a genuine game-changer, capable of charging power-hungry laptops at full speed—a feat most portable chargers can't match. Second, the 24,000mAh capacity is the sweet spot for being airline-compliant while holding enough juice for multiple phone charges or a full laptop recharge. Finally, the smart digital display, which shows real-time wattage, remaining battery percentage, and recharge time, provided a visually compelling feature that looked great on camera and set it apart from a sea of generic black battery bricks.
What the Comments Actually Say
Across platforms, user feedback is consistently positive about performance, with recurring caveats about its physical size.
Reddit users in forums like r/UsbCHardware frequently praise the 737's ability to recharge in under an hour and its powerful 140W output. However, they are also the first to point out its bulk, with one commenter noting it's "not slipping into your pocket comfortably." A few isolated but concerning reports in r/anker mention compatibility issues with Samsung phones and units failing just after the one-year mark.
YouTube reviewers echo this sentiment. Multiple tech channels confirm it remains a top performer even against newer models, lauding its intelligent power distribution and pass-through charging. The most common criticism is its "chunky" form factor. An Amazon reviewer who left a top positive review called the 140W output a "game changer" for powering their MacBook on the go. Conversely, a critical review pointed out a surprising omission for a premium device: it doesn't come with any charging cables.
Technical Comparison
Compared to a standard power bank, the Anker 737 is in a different league. Most portable chargers you'd find for under $50 top out at 18-30W. That's fine for a smartphone, but it will barely keep a modern laptop alive, let alone charge it while in use. The Anker 737's 140W output via USB-C Power Delivery 3.1 is its key differentiator, allowing it to service high-draw devices efficiently.
A standard power bank is for topping off your phone. The Anker 737 is a portable wall outlet for your entire tech arsenal, from a Vision Pro to a MacBook Pro. Its smart display also provides a level of granular control and information that basic LED-indicator batteries simply can't offer.
The Catch
While the performance is undeniable, the primary trade-off is portability. The Anker 737 is heavy and bulky—more akin to a can of soda than a slim battery pack. It's a device you intentionally pack in a bag, not one you casually slip into your pocket. Furthermore, while the majority of users report solid reliability, there are enough scattered reports of units dying after a year or having specific compatibility problems to warrant consideration. Finally, for a premium price, the lack of an included high-wattage USB-C cable feels like an oversight.
