Customer Ratings & Reviews

All in one USB C chargers are now highly sought after after becoming industry standard,I like to stick with one brand and Anker is that brand since day one. Their track record speaks for itself. Now that a majority of devices are using usb type c you don't have to carry a plethora of proprietary chargers anymore. I'm so glad those days are behind us those times were a hassle. That being said let's jump into my review. I have a bunch of devices that use USB type c such as my laptops, Chromebook, tablet, mobile phone, gaming devices like my switch. While they all have different power requirements 40W seems to be the sweet spot for me. It is a power brick and it works as it should. What is important to note is YOU MUST buy quality type c cables to take advantage of the advertised speeds. Not all cables are created equally I opted to also get a pair of anker brand type c braided cables for the best results. I was able to super fast charge my Galaxy Z fold 3 in an hour, my HP Chromebook in less than an hour and 10 minutes with the battery being nearly depleted, my HP Evo laptop in less than 2 hours, my Nintendo switch in less than an hour as well. :::Pros & Cons::: Pros: - small form factor - supports quick charging - inexpensive - 40W is plenty of power to charge most devices Cons: - couldn't find any ::: General thoughts::: I've used this product for a few days and I can't use the default chargers because this is just a much better product than what most devices include a perfect example of this is my Tab S7 it didn't include a quick charger you need to purchase one separately. And the Switch includes just one charging cable which is atrached to the dock. Despite charging a bunch of devices this power brick never was hot to the touch I was amazed by that. This is an example of a perfect product. The only way to make it better is by making a model with more ports and higher charging capacity but those exist already. ::TL;DR If you need a small form factor charging brick then pick this one up it'll charge pretty much anything that supports USB C. One of these in your bag will save you from carrying so many chargers.

This Anker charger is great i use this ti charge my phone and tablet both of which are fast charge items. They both get charged up quickly and this is such a compact charger. Anker always has some of the best charging items out on the market and never fail to make them better. This will replace one of my larger chargers I am currently using and I will get faster charging for my equipment.

Most compact high watt double usc charger out there! I really like that it doesn’t block off other wall outlets under it or to the side of it, unlike bulkier chargers that stick out to the sides too much. Also, $30 is well worth it for the quality. Occasionally on sale for $25 which is a steal.

This little baby is one of the crown jewels of my charger addicifion. Dual 20w ports ebsures im never in red on any of my devices. Being able to also simultaneously charge two things is a game changer. It does get a little warm to rhe touch but nothing to cause concern. Despite folding prongs, this is still a no brainer based on performance and its compact size

This fast, compact charger is great for iPhones, iPads, smaller Macs and most other USB-C power requirements. I have 2 of these, 1 at work and 1 at home. 40w from such a small power brick is impressive (GaN)! This is more powerful than the charger that comes with smaller Macs (30w) as well as twice the power of Apple’s 20w iPad/iPhone charger. You can charge 1 device at 40w or 2 devices at 20w. Great for travel. Highly flexible.

This charger is barely larger than Apple's original 5W charger that we all know, but it pumps out an amazing 40W! (2A at 20V to be exact). Power is shared between ports (so if 2 ports are used - top rating goes down to 20W per port). This adapter is a no-brainer for travel and can charge even your larger power hungry devices (like iPad Pro)! Check pictures for my power tests (and size comparison between Apple's 5W and 29W and Anker's 40W and 60W adapters), it easily put out 35W for my iPad. Helps reduce clutter too (one less brick)!

I absolutely love this charger. It's super fast and super fast chargers my s23 ultra. It's very sturdy and high quality. I highly recommend it to anyone who nees a good charger. It's also small and lightweight.

I have lots of Anker cables and charging blocks but I needed USB-C connections and this charger did not disappoint. Very reliable, charges fast, compact in size, and an amazing product. Hands down one of the best charging products out on the market.

The Anker 521 Powerport lll Nano Pro Duo 40w Fast Charger is a necessity is today’s world where we all have multiple devices that need to be charged no matter where we are. Out of the box it is immediately apparent that this is a quality device. It is compact at approximately 1 3/4” deep and 1 1/3” height and width, yet with a nice amount of weight that reflects the amount of tech inside. The prongs do not fold so they do add some nominal length when carrying the charger. It also comes with an 18 month warranty. The charger features : Power IQ 3.0 which adapts the power output to the maximum speed for your device. Voltage Boost which compensates for cable resistance Real time temperature sensing to assure that the device temperature stays within normal range. Power Tuner Chip adjusts the maximum safe output for your device. Dual USB-C ports which will output 40w from a single port or 20w simultaneously from 2 ports. We have 2 Pixel phones and this is able to rapidly charge both phones at the same time. It will also charge my laptops, though not as quickly at the much larger chargers that were provided by those manufacturers. I travel often and for me this means I no longer have to carry multiple chargers with me, some of which are large and heavy. I can just bring this small charger and know that it will get me by with all of my devices. I am extremely impressed with this charger and would highly recommend this to everyone.

This little bugger is exactly what I was looking for! I already have a plethora of the single port 20 watt chargers from Apple. Those are fine but I found myself switching the USB C cable at least once a day to move from charging my iPhone to my iPad or vice versa. More if I wanted to charge with the Apple Watch fast charger. I went on a search and found this adaptor/wall wart. I have enjoyed Anker's products in the past and now I can add this to the list. It will charge at 40 watts if you have only one device plugged in or 20 watts each with both devices plugged in. I get to leave both device cables in at once and not lose one! Maybe we won't need multiple ports as often if we ever get USB C on iPhone (haha that'll be the day) but until then, this nicely compact charger will do the trick for me.

[Employee of bestbuy] This charger block does everything you need it to. I primarily use it for my Galaxy Watch (10W Draw) and my Fiancée's Apple Watch (15W Draw) and it works perfectly. It does fine with other, more demanding uses too, like my phone (40W draw), as long as only one of the ports is being used.

Works well with the Apple lightning cable and charges fast. Like that it charges for Apple and Samsung. Would purchase this again.

Lots of power in a small package. Works great with my Apple products. It has two USB-C ports that can each produce up to 20 watts of charging power.

The Anker Powerport III Nano Pro Duo 40W Fast Wall Charger is a compact and efficient charging solution designed to meet the needs of modern smartphone users. With dual 20W USB-C ports, it promises rapid charging for devices like the iPhone 15 and Samsung Galaxy series. Available in a sleek white design, this charger aims to deliver power and portability in one convenient package.

It is pretty fast charger. Especially when the top one used only. It charges with full 40W. Pretty small form factor with great price. I wouldn't miss it.

The product is durable and reliable. I use it for all my devices. It is easy to handle and can be transported anywhere.

Compact and good price. It fits easily into my electronics bag. I checked the price of one that only had a single UHC port, and it was much more economical to get the double port.

Charges my devices super fast and works perfectly with my Samsung S25 Ultra. Compact design and great build quality. Highly recommend!

[Employee of bestbuy] I bought this at the begining of march for a trip when i realized there wasnt enough plugs for my devices and i didnt think another individual port block would suffice. I got this little plug!!! Wow i prefer it over the brands. Charges my phone/battery pack, watch or tablet (yes ipad wothout overheating) at the speed of other chargers. You have to share the ports but its great for getting an ipad. Pro 11” charged and my phone overnight.

Works really well, speeds are advertised, will recommend for anyone who uses Type-C.
