Summary

A 24,000mAh, 65W USB-C power bank with two USB-C ports and one USB-A port, built as a laptop-capable travel battery. Check the wattage before you buy: 65W is a total ceiling that splits to 45W + 20W when both USB-C ports are busy, so it will not run laptops that need more than 65W.

Strengths

  • 65W USB-C output charges a 45W-class laptop.
  • Two USB-C ports plus a USB-A port cover most devices.
  • The 30W self-recharge refills the pack quickly with a PD wall charger.
  • Trickle mode handles low-power accessories such as earbuds.

Weaknesses

  • 65W is a total ceiling, not per port; both USB-C ports together drop to 45W + 20W.
  • Only USB-C1 accepts input, so the pack cannot recharge from USB-C2 or USB-A.
  • The 3.5-hour recharge claim needs a 30W PD charger that is not included, and Anker’s own FAQ says 4-4.5 hours.
  • Usable capacity is well below the label: catalog data lists 15,100mAh of real capacity at 5V.
  • It is discontinued in Japan and sold out on Anker’s EU store, so warranty and parts support may be limited.
  • Independent coverage is thin, with owner reports of units not reaching 30W input and one early failure.

Charging a laptop and real capacity

The 65W ceiling is the limit to plan around. Anker rates the pack for one 45W-class laptop, and it cannot run laptops that need more than 65W; when both USB-C ports are in use the output splits to 45W + 20W, and the USB-A port caps at 22.5W. Only USB-C1 accepts input, so charging the pack itself uses that port. Real-world usable capacity is lower than the 24,000mAh label: catalog data lists 15,100mAh at 5V, and Anker documents why rated capacity is lower than expected.

Evidence and owner signals

No instrumented test of the exact A1379 by RTINGS, Wirecutter, Tom’s Guide, CNET or PCMag was found. Macworld’s 2026 coverage is a deal article, not a lab test, and E-Catalog publishes a spec table without measurements. Owner evidence is thin: YouTube titles report units “not reaching 30 Watt Input” tried with other Anker chargers and a 100W cable, and one “broken and useless after a month” unit. These are signals, not defect rates.

Which model this is

This is the 65W Anker 537 (A1379), the 24,000mAh PowerCore 24K for Laptop. Do not confuse it with the 140W Anker 737 (A1289), which has the same capacity but a smart display, 630 g and different dimensions, or with the older PowerCore 26.8K. Anker Japan lists the 537 as discontinued with the 737 as its successor, and Anker EU shows it sold out. The Spanish-market listing is ASIN B0D9ZRHR3Y.

Is it worth it?

Walmart listed it at $69.99 in 2026, and E-Catalog listed it at $56.99 in December 2023. Anker’s 140W 737 lists at $109.99. Under $40 it is strong value if the unit is new with the 18-month warranty intact; $41 to $70 is fair to good and matches the $69.99 Walmart snapshot and the $70 MSRP; above $70 it is weak, given the end-of-life status and the newer Anker models with built-in cables at the same tier.
