Excellent Charger Unit
I bought two of these and they have worked very well for me. I have one by my bed and one by my living room couch. They make it easy for me to charge my MacBook, iPhone, and iPad. The charge is fast and they are small and portable for travel. I highly recommend them.

Charges fast, reliable.
I now have a bunch of these in service around the house and I’m very happy with them. They supply enough power to simultaneously run an Apple HomePod mini as well as fast charge an iPhone pro. I’ve been using them for around a year now, and none of my devices seem to be showing any signs of improper charging performance. I have owned at this point quite a few Anker brand chargers and cables and have been pretty consistently satisfied with most of them. I would say generally I think that the brand has absolutely earned its positive reputation for the solid-state devices, chargers anyway. The cables I think do not quite match the reputation in my personal experience, but in their defense I am extremely hard on hardware. This particular product, the dual USB fast charger, is really hard to beat at any price. I don’t think I’ve yet seen another fast charger this small at any price, and I have tried a handful of other dual USB chargers with this one outlasting all of them so far. Until the same company puts out an updated version of the same thing, this will be the only model of single outlet sized USB adapter I purchase.

Excellent compact charger for your iPhone and Apple Watch
This is a nice charger to keep things compact when you’re charging your iPhone and Apple Watch. It is slightly larger than a standard Apple phone charger. Just as with the Apple charger the prongs do not fold up, so keep that in mind. Perfect for use next to your nightstand. If you use only one of the ports then you’ll be able to get the full 40W output, which allows you to charge your phone at the absolute maximum rate (28W for my iPhone 14 Pro). When using both ports the power will be split evenly into a max of 20W per port… a little overkill for your Apple Watch but still plenty of power to charge up your iPhone. When charging overnight both devices will easily reach full charge while you sleep. If you need to recharge your phone during the day simply plug it in by itself for the fastest possible charge.

Customer Service is great
Edited: Received a replacement at seller's expense and this one works as advertised and at the level and quality I typically see from Anker. Perhaps there was a quality issue with some of them but the customer service experience was excellent.Original review:This is a phenomenal charger for one product. Unfortunately, I purchased this because there are two ports.This did not work for what I would argue is an advertised use-case since 20W is clearly targeted towards an Apple customer. I tried using this with a HomePod mini (came with 20W adapter so likely 9V/2.22A) and iPhone 11 (should draw 18W at 9V/2A) and instead neither charges. Maybe I have a defective unit but I essentially paid extra money for a 40W single-port charger. Should have just purchased 2 of their older ones which definitely work.

IPhone charger
This charges very well. As long as you have the correct cable. If you have an older cable it works fine but doesn’t charge as fast. It will take a little longer to charge your phone. I love this charger because it’s small enough to take with you if you need to. I can’t complain. So far it’s working very well and charges my IPhone in half the time, but I did get a better cable. I would recommend this product.

Great USB C charger
I originally got this for travel, but ended up using it everyday at home. I like that it has 2 outlets for USB C connections. It was a bit bigger than I thought it would be, but better than having to carry 2 charging bricks. I like it so much I bought one for my husband. It's bigger, but doesn't seem to block other sockets when plugged in.

Fell in love with this Charger!!!
Holy Moly!! This Anker charged packs a lot of punch into a very little device. I own many apple brand 20W chargers and after having used this Anker charger, I have noticed that my charge times have significantly improved! I have NOT had any issue with this charger getting warm when using it and I have charged two devices simultaneously.Looks: This charger is a violet color and looks very stylish! it is easily distinguished from other chargers plugged into he wall so that I do not have to worry about which one is mine.Size: it has a good size to it that allows for it to be plugged into my surge protector without it taking up a whole bunch of space or other outlets. I can easily slip this charger into my backpack or pocket without issue. The portability was a huge plus for me and I really liked that it eliminated the need to carry multiple chargers with me.Highly recommend!!

Outperforms an earlier Anker charger 3x its size, plus custom colors
Bought an A2628 in early 2021; for some reason that one balks charging earbuds; often had to unplug and replug-in to get it to charge after too many days on overnight and still low-batt...This one is 1/3 the size, has the same paired smart ports, immediately recognises my earbuds and charges at the same 40W single/20W dual rate... plus is beefy enough to charge a tablet if ever needed.Only complaint is an acrid smell immediately on first charge cycle, so unplugged to make sure I didn't buy a house fire... but all's clear now and whatever produced the odor prolly cooked off...Will update if the rating has to change in long-term use...
