The moment power-hungry road warriors have been waiting for has finally arrived: Anker’s Nano Power Bank with a built‑in retractable USB‑C cable is now on American soil. First teased by savvy gadget sleuths as early as 2024, the compact powerhouse quietly debuted across Europe in June 2025 before landing stateside this month. At $59.99 (with an on‑site 15% coupon available via Amazon or Anker’s own store), it’s posed as the perfect pocket companion for anyone juggling phones, tablets, and laptops on the go.

Late last year, whispers about Anker’s next-gen power bank began circulating on online forums and leak‑tracking blogs. Enthusiasts speculated about everything from fold‑out cables to onboard displays. By June 2025, Anker lifted the curtain in Europe, offering three sleek finishes—black, white, and a muted “sprout” green—at a ¥49.99/€49.99 price point. Now, US customers can finally get their hands on model A1638 without waiting for international shipping delays.

What sets this mini brick apart is its trifecta of charging options:

• Retractable USB‑C cable (up to 45W output), tested to survive 20,000 bends and extend up to 70cm (~27.6 inches).
• USB‑C port delivering up to 45W, ideal for fast‑charging slender laptops and ultrabooks.
• USB‑A port capped at 22.5W, ready for older devices or a quick boost to wireless earbuds.

Given these combined outputs, Anker claims you can juice an iPhone 16 Pro from zero to 50% in just 27 minutes—an eye‑popping stat that aligns well with today’s fast‑paced lifestyles.

Despite packing a 10,000mAh battery, the Nano Power Bank tips the scales at a mere 232g (~0.51 lbs) and measures just 81.5 × 50.5 × 36.0 mm (~3.2 × 2.0 × 1.4 inches). An integrated OLED display up top shows real‑time charge levels and output wattage, so you’re never left guessing how much juice you have left.

Recharging the unit itself is swift, too, thanks to a 30W USB‑C input port. A full refill takes roughly two hours—faster than most competitors in its capacity class. And if you’re the type to travel with both your phone plugged in and the bank tethered to the wall, the convenient pass‑through charging mode ensures all devices replenish at once.

Retractable cables in power accessories have a reputation for snapping under the slightest tug. Anker addresses this head‑on: the built‑in USB‑C cable not only retracts smoothly but stood up to 20,000 bend cycles during internal testing. That equates to daily use for over a decade, according to Anker’s durability claims. A tiny loop on one end even lets you attach a lanyard or clip the unit to a backpack zipper for easy access when you need it most.

In a market awash with bulky “bricks” and flimsy third‑party chargers, the Nano Power Bank’s retractable cable is its standout feature. Competitors like Pitaka and Native Union also offer integrated cables, but few can match the Nano’s combination of output wattage, physical compactness, and price. Meanwhile, Anker’s long‑standing reputation for reliable charging gear gives this newcomer a leg up on less‑known brands.

At $59.99—and with a 15% off coupon currently available—this power bank undercuts many rivals that charge upward of $80 for similar specs. Whether you’re a frequent flyer, commuter, or digital nomad, the Nano Power Bank promises to keep your gear powered without weighing you down. You can pick up your color of choice directly from Amazon or via Anker’s official US storefront, and the coupon remains valid until further notice.
