Detailed overview: Anker 737 PowerCore 24000mAh 140W power bank
The Anker 737 Power Bank, sold as the PowerCore 24K, is a premium pack built for people who need real laptop power on the move, not just a phone top-up. With 24,000mAh (86.4Wh) of capacity and up to 140W of output over Power Delivery 3.1, it stands apart from typical power banks: it charges demanding USB-C laptops, MacBook Pro included, at close to full wall-charger speed.
Three ports (2 USB-C, 1 USB-A) let it power up to three devices at once, with the pack automatically splitting power across whatever is plugged in. The built-in smart display is genuinely useful day to day, showing live input and output wattage, remaining battery percentage, and an estimated time to full charge, so nothing is left to guesswork.
Recharging the 737 itself is unusually fast for its class: it accepts up to 140W, so a full charge takes about an hour with a matching charger, where most packs this large take three or four. That 24,000mAh capacity is enough to charge an iPhone roughly five times over, or take a MacBook Air through more than one full cycle, based on Anker's own figures.
The honest trade-offs are physical: at 630 grams (about 22 ounces) and a genuinely dense, brick-like body, this lives in a backpack rather than a pocket, and the price sits well above entry-level packs, the cost of the capacity and speed on offer. For anyone who needs to keep a power-hungry laptop running through a full travel day without carrying its wall charger, the 737 remains one of the strongest options on the US market.

Comparison
Around $110, the Anker 737 competes with the most capable USB-C laptop power banks sold on Amazon.com, next to searches like "power bank that charges a laptop" or "140W power bank". Here is how it compares with three real US alternatives: the Anker 25,000mAh 165W (its own stablemate), the UGREEN Nexode 25000 200W, and the EF ECOFLOW 25,000mAh 170W.
| Criterion | Anker 737 (24K, 140W) | Anker 25K 165W | UGREEN Nexode 25000 200W | EF ECOFLOW 25K 170W |
|---|---|---|---|---|
| Capacity | 24,000 mAh | 25,000 mAh | 25,000 mAh | 25,000 mAh |
| Total power | 140W | 165W | 200W | 170W |
| Ports | 2 USB-C + 1 USB-A | 3 built-in cables | 2 USB-C + 1 USB-A | 2 built-in cables |
| Observed US price | ≈ $110 | ≈ $120 | ≈ $85 | ≈ $60 |
In short, the 737 still holds its own on capability even though the newer Anker 165W and the UGREEN both edge past it on raw wattage. What keeps the 737 relevant is its display, its genuinely fast 140W recharge, and a long US track record of reliable after-sales support. The ECOFLOW undercuts it on price with detachable cables built in, but the 737 remains the safer pick for anyone who wants a proven laptop-charging power bank without chasing the very newest spec sheet.

Our tester's review: Guillaume Hoarau
The 737 is the pack we reach for when a laptop has to survive a full day away from an outlet. Its 140W puts it in a small club of power banks that can genuinely charge a MacBook Pro at close to wall-charger speed rather than just slowing the drain, and over a working day it kept a laptop, a phone, and a pair of earbuds all topped up without breaking a sweat. The smart display earns its keep daily: you see exactly what wattage is going out and how much runtime is left, no more guessing from blinking LEDs. Recharging is genuinely fast too, close to an hour with a good 140W charger, which is rare for a pack this size. The trade-offs are the ones you would expect: at over 22 ounces it has real heft in a bag, and the price sits above most 20,000mAh packs. Amazon reviewers echo our experience closely, praising the display and raw charging speed while a handful flag reduced capacity after a year or more of heavy use, which tracks with any lithium pack pushed this hard. For genuine laptop-charging duty on the road, it remains one of the clearest benchmarks around.

Yes, and that is its main selling point. At 140W output it charges most USB-C laptops close to full speed, including a MacBook Pro, something very few power banks can do.
Its 24,000mAh charges an iPhone roughly five times over, or takes a MacBook Air through more than one full charging cycle, based on Anker's own published figures for this pack.
It accepts up to 140W input, so a full recharge takes about an hour with a matching charger, far faster than most power banks in this 20,000mAh-plus capacity class.
Yes. At 86.4Wh it stays under the 100Wh cabin limit set by US and most international airlines, so it travels in carry-on like any standard power bank.
