A perfect upgrade to fast charging
I bought this Anker 20W Nano Pro charger as a Christmas gift for my parents, teaming up with my brother, and it ended up being a great choice. They’ve always used older, slower chargers around 15W, so this was their first experience with a “fast” charger. The difference was immediately noticeable, and they absolutely love how much quicker their phones charge now. The size is another huge plus. It’s incredibly compact, which makes it perfect for travel and easy to keep plugged in without taking up space. Despite how small it is, it delivers reliable power every time. I recommended this charger because I’ve been using Anker’s 45W Nano charger myself, and it’s been rock solid in both performance and size. Anker has consistently impressed me as a brand, so I felt confident giving this as a gift. Turns out I was right, it’s been a big upgrade for my parents and one they genuinely appreciate.

Anker is always good quality!
Seems to charge devices more quickly than older models and does not seem as hot to the touch. Reliable as I have a couple other Anker products, including a pink charging block for my daughter, that have been well used over several years! The price is a good value for the product, no cord needed, I will purchase other Anker products again!

Purchased Twice because of Value
The primary reasons for my purchase of two Anker Nano Pro Power Adapters were their quality, competitive pricing, and exceptional value. Anker is a reputable brand renowned for producing high-quality products. Additionally, the adapter’s PD protocol feature enables it to dynamically adjust the power transfer rate to optimize charging efficiency. While the adapter occasionally generates heat during use, this is a minor drawback. I highly recommend the Anker Nano Pro Power Adapter.

My favorite travel charger
This is perhaps the perfect phone charger to pack for travel. 1) It's small which is always important when packing. Small as in the original apple charger small. For a simple phone charger don't need a huge plug (hello, looking at you ANKER 735). This is clearly only as big as need to fit the circuitry and nothing more. Compact, clean, solid. My only critique in design is that the plugs are fixed, not foldable. A reasonable tradeoff for a charger this small. 2) Single USB-C port, which is all you need for a smartphone. I honestly travel with very few electronics anymore so I don't need multiport chargers. One phone = one port. 3) 20W, which might be a drawback for some as it won't handle some of the larger, more power demanding devices, but that's not it's purpose. It's designed for iPhone and it works perfectly for that. It will keep up with the power draw if you're using your phone continuously while plugged in and will take it from 0 to 50% in about 30 minutes while monitoring temperature/power draw so it doesn't overheat or over charge. The only really complaint is it's small enough I've misplaced and replaced this 4 times, which is more my issue and not the devices. Great little charger, now they just need to integrate an Apple AirTag so I stop losing them :D

It’s cute, it’s little, and it works!
I’m really impressed by this little charging block. I have this paired with a 6’ mfi certified charging cable and I can charge my iPhone 17 from less than 10% up to 100% in about 90 minutes. Love the different color options. When you have a house full of iPhone users, charger blocks tend to get passed around. Now I know which one is mine. I plan on purchasing another one for the living room.

The Anker 511 Charger (Nano Pro) has been a fantastic addition to my tech gear. It’s impressively compact but packs a punch with a 20W output, which charges my devices much faster than the standard chargers. It works great with multiple device types, making it versatile and ideal for my iPhone and iPad. Despite its power, it stays cool and operates quietly. Highly recommended for anyone needing a reliable, fast charger!.

lo que me gusta es que es mas pequeño y barato que el cargador oficial de apple y viene en una caja pequeña lo cual es mejor para el ambiente,carga alrededor de la misma velocidad y no se calienta.
