Anker Nano Power Bank 20K – Powerful 30W Built-In USB-C Cable Power Bank in Sri Lanka | FoneHouse

Never worry about running out of battery on the go with the Anker Nano Power Bank 20K — a massive 20000mAh portable charger that combines Anker’s signature quality, powerful 30W fast charging, and the ultimate convenience of a built-in USB-C cable in one ultra-compact and travel-friendly package. Whether you are commuting, travelling, studying, or working remotely, the Anker Nano Power Bank 20K keeps all your devices powered up without the hassle of carrying separate charging cables.

The Anker Nano Power Bank 20K features a built-in USB-C cable that is integrated directly into the power bank body — simply pull out the cable, plug it into your device, and start charging instantly with no separate cables needed. The 30W bidirectional Power Delivery charging works in both directions — delivering 30W of fast charging output to your devices and accepting 30W of fast input to recharge the power bank itself, bringing it to 50% in just 45 minutes. When paired with the built-in USB-C cable, the Anker Nano Power Bank 20K can charge an iPhone 15 to 50% in just 30 minutes — one of the fastest charging speeds available from any portable power bank.

With a massive 20000mAh battery capacity, the Anker Nano Power Bank 20K can charge an iPhone 15 up to 4 times, a Samsung Galaxy S24 up to 3 times, or keep a MacBook Air running significantly longer on a single full charge — making it the perfect power solution for heavy users, frequent travellers, and anyone who needs serious backup power on the go. The intelligent colour digital LCD screen clearly displays the remaining battery percentage, estimated usage time, and current charging rate — so you always know exactly how much power you have left without any guessing.

Despite its enormous 20000mAh capacity, the Anker Nano Power Bank 20K is designed to be ultra-compact and lightweight, making it easy to slip into any pocket, bag, or backpack for truly go-anywhere portability. The built-in handle adds even more carrying convenience. Airline safe and universally compatible with all USB-C devices including iPhone 16, 15, 14, Samsung Galaxy S25, S24, S23, Google Pixel, MacBook Air, iPad Air, AirPods, and more, the Anker Nano Power Bank 20K is simply the most complete and best value 20000mAh power bank available in Sri Lanka today.
