    • Sturdy Build, Fast Charging, and Super Portable
Color: Arctic White
I chose this product over others because it offered the best mix of port capacity, charging speed, and compact foldable design — all at a reasonable price point. It has enough ports to charge all my devices at once, and the cord length is generous enough without being bulky. The build quality feels sturdy and premium, and the foldable design makes it super easy to carry in a backpack or drawer. I've used it while traveling and at home, and it's performed consistently well. The charging capacity is impressive — even my tablet charges quickly. Highly recommended for anyone who wants a reliable and portable power solution! ... show more

    • Best Charger For iPhones!!
Color: Arctic White
The Anker 511 Charger is a tiny powerhouse that charges your devices super fast and reliably. Whether I’m at home, church, or on the go, this charger has become my go-to. With 20W of power, it charges my USB-C devices like my phone and tablet in a flash. My phone goes from 0 to 50% in just about 30 minutes, which is a huge time saver. And even though it’s small, it doesn’t skimp on performance. What I love most is how small it is. It fits in my pocket or bag without taking up much space, making it perfect for travel or when outlets are scarce. The build quality is top-notch, just like Anker products. It feels solid and durable, and I trust it to keep my devices safe with its built-in safety features. And it’s super quiet—no buzzing or heat buildup, even when I use it for a while. If you need a reliable and efficient USB-C charger, the Anker 511 is a great choice.

    • Fast Charger
Color: Arctic White
I recently purchased the Anker USB C Charger 20W, also known as the Nano Pro, and I couldn't be happier with this compact and powerful charger. It's proven to be a reliable and efficient charging solution for my devices. First and foremost, the size of the Nano Pro is incredibly compact. It's small enough to fit in the palm of your hand, making it perfect for travel or everyday use. Despite its size, it delivers a powerful 20W charge, ensuring that my devices charge quickly and efficiently. The PIQ 3.0 technology is a standout feature. It's designed to provide a fast and stable charge, which is essential for busy individuals who need their devices ready to go in no time. I've noticed a significant reduction in charging time compared to other chargers. Compatibility is another advantage of the Nano Pro. It works seamlessly with a variety of devices, including the latest iPhone models (14/14 Plus/14 Pro/14 Pro Max), Galaxy phones, Pixel, iPad, and iPad mini. It's a versatile charger that can handle all your USB C devices. The build quality is excellent, as expected from Anker. It feels durable and well-constructed, ensuring that it will withstand daily use and travel without any issues. One thing to note is that this charger does not come with a cable included, so you'll need to use your own USB C cable. However, this allows for flexibility in choosing the cable length and type that suits your needs. In summary, the Anker USB C Charger 20W, Nano Pro, is a top-notch charging solution for a wide range of devices. Its compact size, fast-charging capabilities, and compatibility with various gadgets make it an excellent choice for those who value efficient and reliable charging. I highly recommend this charger to anyone in need of a high-quality USB C charger for their devices. ... show more

    • Small but Powerful — A Must-Have Charger!
Color: Arctic White
Anker never disappoints! This 20W Nano Pro charger is compact, lightweight, and charges my devices incredibly fast. I use it with my iPhone and iPad, and it powers them up way quicker than the old standard chargers. The build quality feels premium, and it doesn’t overheat even with extended use. I also appreciate the sleek, minimalist design — it fits easily into my bag or even my pocket when I’m on the go. No cable included, but that’s clearly stated. If you already have a USB-C to Lightning or USB-C to USB-C cable, you’re good to go. Highly recommend for anyone looking for a reliable fast charger in a small package! ... show more
