Lightning fast, super compact, and totally worth it!
Color: Black
Amperage: 2.22 Amps
I am so impressed with this charger! I paired this Anker 20W Nano Pro with the Anker New Nylon USB-C to Lightning cable for my iPhone 13 Pro Max, and the charging speed is insane, I literally gain 2% battery in about a minute. It’s way faster than any other charger I’ve used. Beyond how well it works, the design is super sleek, simple, and compact (honestly really cute!). It’s a bit pricier than basic chargers, but it is 100% worth every penny. Big fan of Anker now!

Charges quickly, compact size, good value.
Color: Black
Amperage: 2.22 Amps
I really like this - I've bought several, and just bought another. I realized that when I'm sitting in my recliner, my iPad wasn't charging as long as I was watching something - the charge kept decreasing. I ordered another one (I already have them in other locations), and my iPad has already charged several percent, while I'm watching. It's compact size is perfect. I've had two others for a year and a half, and they're still working fine.

Still one of the best 20W travel chargers after a year
Color: Black
Amperage: 2.22 Amps
This has become the charger my family actually grabs when we travel. Super compact, light, and it consistently delivers full 20W to phones and Nintendo devices that max out around that power level. "GaN" technology is the reason it packs real output into such a small body, most chargers are using older tech. After more than a year of regular use it still performs the same. No slowdown, no weird heat issues in normal phone charging. Two clear limits: it is not for laptops, and this version does not have folding pins. That is my only real complaint. Everything else about it just works. If you need a reliable, pocketable 20W charger for phones, Nintendo Switch, or similar devices, this remains one of the best options on the market.

Compact and Reliable Fast Charger for Modern Devices
Color: Black
Amperage: 2.22 Amps
The Anker 511 Charger (Nano Pro) is a 20W USB-C charger designed for quick and efficient charging of a wide range of devices, including iPhone 16 series, Samsung Galaxy, Google Pixel, and iPads. Its compact design and advanced charging technology make it a convenient accessory for users who need fast and reliable power on the go. I tested it with multiple devices to evaluate its performance, compatibility, and convenience. Pros: ✅ Compact Design: Lightweight and portable, making it perfect for travel or everyday use. ✅ Fast Charging: 20W output powered by Anker’s PIQ 3.0 technology charges devices quickly and safely. Cons: ❌ Cable Not Included: Requires a separate purchase of a USB-C cable if you don’t already own one. ❌ Limited Ports: Single USB-C port, which may not suffice for users needing to charge multiple devices simultaneously. Performance and Usability: The Anker 511 Charger delivered excellent performance during testing. It fully charged an iPhone 16 Pro from 0% to 50% in approximately 30 minutes, matching advertised speeds. It remained cool during operation, a testament to its built-in safety features. The single-port design ensures focused power delivery but limits multitasking. Its compact form factor fits easily into tight spaces or travel bags without adding bulk. Comparison: Compared to standard 5W chargers, the Anker 511 provides significantly faster charging times. Its compact size and reliability give it an edge over bulkier fast chargers. While multi-port chargers may offer more versatility, the Nano Pro excels in portability and single-device efficiency. Who Is This For?: This charger is ideal for users who need a portable and fast charging solution for a single device. It’s perfect for travelers, students, and professionals who prioritize compact design and reliable performance. Conclusion: The Anker 511 Charger (Nano Pro) combines speed, safety, and portability into a sleek package. While the lack of an included cable and single-port design might be limiting for some, its performance and build quality make it an excellent choice for those who need an efficient charger for modern USB-C devices.

Good smartwatch charging block

Great, but up sized.
Color: Black
Amperage: 2.22 Amps
Works as advertised and fits between other plugs on a power strip. Bought as a replacement for the discontinued PowerPort PD Nano. This newer model is noticably heavier and bigger and just doesn't feel as satisfyingly small in hand, but considering its price and availability, it's a fine replacement. In the end, I actually chose the slightly taller Nano 3 (30w) as a replacement. Besides the extra height, that model has a smaller base area footprint, feels lighter, and has a folding plug (which makes up for the height, at least when carried). Side note: originally order this in black, but received a gray model.
