The Anker PowerPort III Cube 20W Wall Charger with PowerIQ 3.0 – A2149K21 is a compact, high-performance single-port USB-C wall charger featuring a foldable plug for easy portability and storage, making it an ideal travel companion or everyday home/office solution. Powered by Anker’s advanced PowerIQ 3.0 technology combined with USB Power Delivery (PD), it delivers up to 20W of fast charging output (with profiles like 5V=3A / 9V=2.22A), enabling rapid power-ups—such as charging an iPhone 14/15/16 series or similar models to 50% in about 25–30 minutes, roughly 3x faster than a standard 5W charger. The ultra-small cube design (approximately 32.3 × 31.8 × 33 mm and weighing around 38–44g) protrudes minimally from outlets, with a sleek white finish (UK plug variant for this model) that blends seamlessly into any setup while supporting wide voltage input (100-240V ~ 0.7A 50-60Hz) for global use. It offers broad compatibility with USB-C devices including iPhones (12/13/14/15/16 series and later), iPads, Samsung Galaxy phones, Google Pixel, and other PD-compatible gadgets (note: cable not included; use a quality USB-C cable for optimal performance). Enhanced with Anker’s MultiProtect safety features—including over-voltage, over-current, short-circuit, and temperature protection—it ensures safe, efficient charging without overheating risks. This reliable, value-packed charger serves as a superior alternative to bulkier or slower adapters, backed by Anker’s trusted quality and typically an 18-month warranty.

FAQs
How fast does it charge an iPhone?
It supports up to 20W USB Power Delivery, enabling fast charging where compatible iPhones (like iPhone 12 through 16 series) can reach approximately 50% battery in 25–30 minutes. This is about 3x faster than a standard 5W charger, though actual times vary slightly depending on the model, starting battery level, temperature, and the cable used.
Is a charging cable included, and what type do I need?
No cable is included with this charger. Use a high-quality USB-C to USB-C cable (for newer iPhones or Android devices) or USB-C to Lightning cable (for older iPhones) rated for at least 20W/3A to achieve full fast-charging speeds. Anker recommends their own PowerLine cables for best performance and safety.
Does it work with non-Apple devices like Samsung or Google Pixel phones?
Yes, it’s broadly compatible with any USB-C PD device, including Samsung Galaxy phones (for standard PD fast charging), Google Pixel, iPads, and other tablets or gadgets. It delivers up to 20W based on what the device negotiates, though some Android phones may cap at lower speeds if they require proprietary protocols beyond standard PD.
