Lightning-Fast Charging Speeds
The Anker Nano Pro delivers a powerful 20W output via its USB-C port, making it an exceptional choice for fast charging. It is engineered to significantly reduce the time you spend tethered to an outlet. For instance, when paired with a USB-C to Lightning cable, it can charge an iPhone 14 from a depleted battery to 50% capacity in a mere 27 minutes. This is up to three times faster than the older 5W chargers that were previously standard. This rapid power delivery is ideal for quick top-ups before leaving the house or for efficiently powering up your devices during a busy day, ensuring you always have the battery life you need without the long wait.
Incredibly Compact and Portable Design
One of the standout features of this charger is its remarkably small footprint. Measuring just 1.16 inches on each side, the Nano Pro is 45% smaller than a conventional 20W charger. This miniature size is a game-changer for portability, allowing it to fit easily into the tightest of spaces, such as an overstuffed backpack pocket, a small purse, or even your pocket. This makes it the ideal travel accessory, providing a high-power charging solution without adding bulk or weight to your load. Its lightweight design of just 1.1 ounces means you’ll barely notice it’s there until you need it.
Advanced Safety with ActiveShield Technology
Anker has equipped the 511 Nano Pro with its latest ActiveShield safety system to provide comprehensive protection for your valuable devices. This multi-tiered security system is far more advanced than standard chargers. It features a Dynamic Temperature Sensor that actively and continuously monitors the charger’s temperature to prevent overheating. Additionally, a built-in Power Tuner Chip intelligently adjusts the power output to safeguard your connected device from potential damage caused by irregular current or voltage. This ensures that while you enjoy rapid charging, your device’s battery and internal components are always protected, giving you peace of mind.
Broader Device Compatibility
The Anker Nano Pro is highly versatile, offering fast charging for a wide spectrum of devices beyond just the latest iPhones. Its compatibility list includes the iPhone 14, 13, 12, and 11 series, as well as the iPhone SE, XS, XR, and 8. It also provides efficient power to various iPad models, including the Pro and Air series. For Android users, it is compatible with devices like the Galaxy S10 series and Google Pixel 3, 4, and 5. It is also a useful charger for AirPods and Apple Watch. However, please note that while it can charge the Nintendo Switch, it does not support “Charge-and-Play” functionality in TV mode, and it does not support Samsung Super Fast Charging for newer Galaxy models like the S20 or S21.
Smart Charging and Battery Protection
The charger is designed to intelligently manage the charging process to optimize battery health. Due to the safety requirements of lithium batteries, the charging speed is not linear. The Nano Pro will deliver its maximum power output to push your phone’s battery from 0% to 50% at an accelerated rate. Once the battery reaches this mid-point, the charging speed will gradually taper down to protect the battery’s long-term lifespan and prevent overcharging. This intelligent speed management ensures that you get the fastest possible charge when you need it most, while also prioritizing the health and longevity of your device’s battery over the long term.
Stylish Finishes to Match Your Style
The Anker 511 Nano Pro transcends the typical utilitarian look of most chargers by offering a range of stylish finishes designed to complement the aesthetic of modern devices. It is available in six fresh colors that are specifically designed to beautifully match the look of your iPhone and other gadgets. This design-forward approach allows you to personalize even your charging accessories, making the Nano Pro not just a functional tool but also a stylish addition to your tech collection. Whether you prefer a classic look or something more vibrant, there is a finish to suit your style.
