Anker Nano Power Bank (10K, 45W, Built-in Retractable USB-C Cable) Black

Anker Nano Power Bank (10K, 45W, Built-in Retractable USB-C Cable) — Black

The Anker Nano Power Bank packs a 10,000mAh battery and a 45W retractable USB-C cable into a pocket-sized shell. It suits commuters, travelers, and students who want fast phone charging without carrying a separate cable. Additionally, the built-in display shows exactly how much power remains, so guessing about battery life becomes unnecessary.

Technical Specifications

Battery & Capacity

• Capacity: The battery carries a 10,000mAh rating, though energy loss during conversion typically delivers 5,500-6,500mAh of usable charge.
• Recharge time: It fully recharges in about 2 hours, provided a 30W or higher USB-C Power Delivery adapter powers the input.
• Usable charges: Because capacity varies by device, it provides roughly 2 full smartphone charges for most phones.

Charging Ports & Output

• USB-C port and built-in cable: Each supports up to 45W independently, and both additionally work with USB Power Delivery, Quick Charge, and Samsung PPS 2.0.
• USB-A port: This port supports up to 22.5W, which suits older devices or accessories without USB-C.
• Multi-port charging: When several devices connect at once, output splits, so USB-C drops to roughly 15W while USB-A falls to 7.5W.
• Laptop compatibility: Since 45W falls below most laptop charging needs, a 20,000mAh or higher power bank suits laptops better instead.

Cable Design

• Retractable cable: The cable extends to 70cm (27.6 in), and it retracts flush into the housing when not needed.
• Durability: Because Anker rates the cable for over 20,000 bend cycles, daily pulling and retracting should not wear it out quickly.
• Locking lengths: The cable stops at six increments roughly 4 inches apart, so it holds a chosen length throughout use.

Physical Design

• Dimensions: At 81.5 x 50.5 x 36.0mm (3.2 x 2.0 x 1.4 in), it takes up roughly the footprint of two AirPods cases stacked together.
• Weight: The unit weighs 232g (0.51 lb), close to the weight of a large smartphone.
• Colour: This model comes in black, though white and green versions are also available.
• Display: An integrated screen shows battery percentage, and it additionally reports per-port wattage output.

Use Cases & Applications

Does the Anker Nano Power Bank work with Samsung phones as well as iPhones?

Yes. The USB-C port and cable support Samsung PPS 2.0 fast charging, along with standard Power Delivery for iPhones and other USB-C devices.

Can it charge a laptop?

Not effectively. The 45W maximum output suits phones, tablets, and earbuds, however most laptops need more power than this bank can deliver.

How long does a full charge actually last?

Battery life depends on device and usage, but the 10,000mAh capacity typically provides about 2 full smartphone charges before needing a recharge itself.

Is the retractable cable durable enough for daily use?

The cable carries a 20,000-bend rating, so regular daily pulling and retracting should not cause premature wear under normal handling conditions.
