Anker Power Bank (25K, 165W, Built-in USB-C and Retractable Cable)

The Anker Power Bank (25K, 165W, Built-in USB-C and Retractable Cable) is a high-capacity portable charger designed for people who travel with a laptop, phone, and other USB-C gear. Its 25,000mAh cell delivers up to 165W across three USB-C ports plus a USB-A port, so a laptop and phone can charge together without slowing down. This power bank suits commuters, remote workers, and travellers who need dependable power without carrying a separate charging cable.

Technical Specifications

Capacity & Power

• Battery capacity: 25,000mAh. For instance, this typically charges a phone up to 5 times or a laptop once on a single charge.
• Total output: 165W max when charging two devices. However, output drops to 130W max when charging three or four devices simultaneously.
• USB-C output: Up to 100W per port. Additionally, this applies across all three USB-C connections (built-in retractable cable, built-in strap cable, and standard port).
• USB-A output: Up to 33W, suitable for phones and smaller accessories.

Charging Behaviour

• Recharge input: Up to 100W from any USB-C port, reaching 30% capacity in about 20 to 22 minutes. However, 100W peak recharging only applies once the battery holds above 25% charge.
• Laptop charging speed: For instance, a 16-inch MacBook Pro (M3) reaches 50% in about 33 minutes using the built-in cable.
• Phone charging speed: Similarly, an iPhone 16 reaches 50% in around 25 minutes.
• Trickle charging: A dedicated low-power mode charges earbuds and other small accessories through the USB-A port.

Physical Design

• Weight: 21 oz (approximately 595g). Consequently, this size suits a backpack rather than a jacket pocket.
• Built-in cables: One retractable USB-C cable rated for over 20,000 retractions, plus a fixed 0.98 ft USB-C cable rated for over 20,000 bends.
• Safety system: ActiveShield 2.0 technology monitors temperature roughly 3 million times per day to keep charging stable.
• Air travel: Additionally, the battery capacity meets common airline carry-on limits for portable lithium-ion chargers.

Use Cases

Will this charge a laptop and phone at the same time?

Yes. The Anker Power Bank (25K, 165W) delivers full-speed output to two devices at once, though total output drops to 130W when three or four devices connect simultaneously.

Do I need to carry a separate charging cable?

No. Two built-in USB-C cables cover most charging needs directly, and one doubles as a carrying strap. Additionally, a standard USB-C port and a USB-A port remain available for extra devices or cables.

Is this power bank suitable for air travel?

The 25,000mAh capacity stays within the range most airlines accept for carry-on lithium-ion batteries. However, exact rules vary by airline, so checking with the specific carrier before a flight remains a sensible step.
