Anker 737 PowerCore 24K Review: The Reliable Workhorse

The Anker 737 PowerCore 24K is the power bank equivalent of a Honda Accord — not the flashiest, not the cheapest, but reliably excellent in every way that matters. With 140W USB-C output and 87.36Wh of capacity in a solid aluminum chassis, it hits the sweet spot for laptop users who want something they can trust.

Key Specs at a Glance

• Capacity: 24,000mAh / 87.36Wh
• Max Output: 140W USB-C (PD 3.1)
• Ports: 2x USB-C, 1x USB-A
• Recharge: 0-80% in ~40 minutes
• Weight: 1.3 lbs

Who Is It For?

Laptop users who want a premium, well-built power bank that charges fast and recharges even faster. If you value build quality and brand reliability over squeezing every last milliamp-hour for the dollar, the 737 is the one to buy.

140W PD 3.1 That Just Works

The primary USB-C port delivers 140W via PD 3.1, which means full-speed charging for MacBook Pros, Dell XPS models, and most USB-C laptops. In our testing, it charged a MacBook Pro 14-inch from 20% to 80% in under an hour — nearly indistinguishable from wall charging. Anker’s power delivery implementation is rock-solid; we never experienced a single failed negotiation or unexpected disconnect.

Rapid Self-Recharge

One of the 737’s standout features is how quickly it recharges itself. With a compatible charger, it goes from 0-80% in about 40 minutes. That’s fast enough to top it off during a lunch break before heading back out. The smart digital display shows charging wattage and estimated time remaining, so you always know where you stand.

The Trade-offs

At 87.36Wh, the 737 falls short of the Anker Prime’s 99.54Wh and the Ugreen Nexode’s 90Wh. You’ll get roughly one MacBook Air charge or about 80% of a MacBook Pro 14-inch. Three ports (2C + 1A) is adequate but not as generous as the Ugreen’s four. And at 1.3 lbs, it’s noticeably heavier than the Baseus Blade 2, though the aluminum build quality partly justifies the weight.

The Bottom Line

The Anker 737 PowerCore 24K is the best all-around laptop power bank under $120. It doesn’t win any single category outright, but it has no real weaknesses either. The 140W output, fast recharging, and Anker’s proven reliability make it an easy recommendation for anyone who charges laptops on the go.
