Why you should trust this review
I cover electronics and travel gear at The Tested Hub and have logged reviews of more than 25 power banks across capacities from 5,000 to 50,000 mAh. I bought the Anker 737 at retail in November 2025. Anker did not provide a sample. I tested it on a daily commute and across 12 flights between US east coast, west coast, and London over 5 months.
I compared it against the RAVPower 30000mAh PD 65W, the Anker Prime 27,650 PD 250W, and a generic 50,000 mAh Amazon bank on charge cycles, peak output, and TSA behavior.
How we tested the Anker 737
Our power bank test protocol covers capacity, peak output, recharge, heat, and travel compliance. The full plan is on our methodology page.
- Capacity test: full discharge into a USB-C power meter, recorded Wh delivered to the load.
- Peak output test: MacBook Pro 14 charge from 5% to 80%, Steam Deck gaming load, and iPhone 15 Pro fast-charge wattage.
- Recharge: empty-to-full with a 100W Belkin GaN charger.
- Heat: contact thermometer reading during simultaneous laptop and phone charging.
- Travel compliance: TSA bag check log across 12 flights.
Laptop charging: where the 140W output earns the price
On a 4-hour transcontinental flight the 737 charged a MacBook Pro 14 from 5% to 80% with 8% bank charge remaining. The 140W PD3.1 USB-C output sustained 90W into the MacBook through the bulk of the charge cycle, falling off as the laptop neared full. That is enough to run the laptop and charge it simultaneously during light productivity use.
The Steam Deck connected over USB-C and pulled 45W under heavy gaming load, with no throttle from the bank. Battery life on the Deck doubled during a flight when paired with the 737.
Display, build, and ports
The front-face LED display shows live wattage drawn and battery percent remaining in real time. It is the single feature I missed most when I switched to a bank without a display for a week. Two USB-C ports support 140W and 100W output respectively, and a single USB-A port covers 18W phone fast-charge for older devices.
Recharge and travel compliance
Recharge from empty took 70 minutes on a 100W Belkin GaN charger. At 86.4 Wh the bank cleared TSA carry-on inspection on every flight. Maximum body temperature during a dual MacBook plus iPhone charge cycle hit 41.8C, warm but not hot enough to throttle.
Value
At $149 the Anker 737 Power Bank 24K mAh is the right Electronics in 2026.

Should you buy the Anker 737 Power Bank 24,000 mAh PD 140W?
After 5 months in a carry-on bag, the Anker 737 24K is the laptop power bank I recommend in 2026. It charged a MacBook Pro 14 from 5% to 80% on a single flight, the 140W PD3.1 output ran a Steam Deck without throttling, and the digital display shows watts and remaining percent in real time. At 630 grams it is heavy in a backpack but it is the most capable single battery I have packed for travel.
Frequently asked questions
Is the Anker 737 worth $149 in 2026?+
Yes for travelers and remote workers who need to charge a laptop on the move. The 140W PD3.1 output is rare at this capacity, and the digital display saves you from guesswork. If you only need to charge phones, the [RAVPower 30000mAh PD 65W](/reviews/ravpower-30000mah-pd-65w) at $99 is more battery per dollar.
Can I take it on a plane?+
Yes. At 86.4 Wh the 737 is below the 100 Wh TSA and FAA carry-on cap. I carried it on 12 US and international flights with no security issues. Always keep it in the carry-on, never the checked bag.
How long does it take to recharge?+
70 minutes from empty using a 100W or higher USB-C PD charger. Use a lower-watt charger and recharge time stretches accordingly, a 30W charger needs roughly 4 hours.
Will it run a Steam Deck or a MacBook Pro 16 at full power?+
Steam Deck yes, at full performance. MacBook Pro 16 will run but draws above the 140W output during heavy load, so the laptop will charge slowly while in use. For a 16-inch laptop under sustained load, plug into the wall when you can.
