Anker A1638 Nano 45W Power Bank — 10000mAh with Built-In Retractable USB-C Cable

Anker A1638 Nano — The Cable Is Already There. That’s the Point.

The worst thing about power banks isn’t the weight, the bulk, or even the price. It’s forgetting the cable. The Anker Nano A1638 eliminates that problem permanently — the charging cable is built in, retractable, and always with you. Add 45W fast charging and a crisp smart display, and you have the most practical 10,000mAh power bank you can carry.

🪢 InstaCord — Built-In Retractable 70cm USB-C Cable

Pull the InstaCord out of the Nano’s body and it extends to 70cm — long enough to reach your phone in your pocket while the power bank stays in your bag. Let go and it retracts cleanly. The cable is rated for over 20,000 bends without degradation — built to last years of daily use. One pull. Charge. Done.

⚡ 45W Fast Charging — Half a Charge in Under 30 Minutes

With 45W USB-C Power Delivery, the Nano charges an iPhone 16 Pro to 50% in 27 minutes. Samsung Galaxy devices hit 50% in a similar window. This is true fast charging — not the “fast” label slapped on a 15W device. For a 10,000mAh power bank, this speed is genuinely remarkable.

📦 16% Smaller Than the Competition

The Nano is designed specifically to be 16% smaller than comparable power banks with retractable cables — ultra-compact without sacrificing capacity. It’s slim enough to sit alongside your phone in a single pocket. The Nano design philosophy is “less bulk, same power,” and it delivers.

📺 Smart Intelligent Display

The real-time display shows battery percentage, live output wattage, and input wattage while recharging. You always know exactly how much power remains and how fast you’re charging — no guesswork, no LED dot approximations.

↕️ 30W Two-Way Charging + Pass-Through

Recharge the Nano itself at up to 30W input for a full refill in approximately 2 hours. Pass-through charging allows you to charge a device while the power bank recharges simultaneously — plug in, plug on, go.

🛡️ Anker MultiProtect + 24/7 Safety

Anker’s MultiProtect system covers overcharging, overheating, over-voltage, and short-circuit events — protecting both the power bank and your connected device around the clock. Compatible with Samsung Fast Charging 2.0 for Android users.
