This morning, I had an iPad Pro plugged in with the matching purple cable. When unplugged the box from a surge protector, it exploded! I thought my house was going to catch on fire.

This morning, I had an iPad Pro plugged in with the matching purple cable. When unplugged the box from a surge protector, it exploded! I thought my house was going to catch on fire.

1. Anker 521 Nano Pro 40W dual port (This device)
33 watts while charging a laptop. Other port not connected.
16 watts when the second port is connected to another USB-c device.
Compare the performance against other Anker USB-c chargers.
2. Anker 713 Nano II 45W
3. Anker Powerport Atom III 45w
They both delivered 37 watts.
-- Dec 18, 2021 update --
Anker sent me another Nano Pro 521 to test. I rerun the test using the same laptop but discharged to a different level. I used Anker 100-watt 3 ft USB-c to USB-c cable with Kavalan 100-watt USB power meter. I cross checked the values using a Choetech USB power meter. I ran the test three times and used the best numbers. I also included the initial estimated time to full charge.
The Nano Pro “IQ” port designates the port closer to the “IQ” label.
Both 1st and 2nd shipment Nano Pro 521 delivered about 4 watts less with about 10% longer estimated time to full charge compared to other Anker 45-watt chargers. At 36-watt demand, I expected the Nano Pro 40-watt charger to kept up with the Anker 45-watt chargers.
On the 1st shipment Nano Pro 521, the “IQ” side port initially registered 5.1 volts with 0 amp this time. After plugging and unplugging the charger several times, the port started working.
Nano Pro 521 40W model A2038 - 1st shipment
"IQ" port = 31.6 watts, 1hr 52min
"other" port = 31.0 watts, 2hr 8min
Nano Pro 521 40W model A2038 - 2nd shipment
"IQ" port = 31.6 watts, 1hr 54min
"other" port = 31.8 watts, 1hr 54min
Powerport III 45w model A2711
35.9 watts, 1hr 46min
Nano II 45w model A2664
35.8 watts, 1hr 42min
Powerport Atom III 45w model A2617
35.9 watts, 1hr 43min
OEM Laptop charger brick
53.3 watts, 1hr 24min
Only down side is that we of course had to buy another charging cable for her because this charging brick only accepts USB-C type inputs, and all of her cables were USB-A type inputs. So that meant buying new charging cables, which was it too bad it needed to be done anyway but that just meant that new cables were needed before being able to use this charging brick/block. But in buying the new cable, it helps in lowering the charging time and speeding up the charging process.
Would be nice to see a package deal or combo deal offered to help buyers ensure that they get the proper cable to take advantage of the excellent charging times and fast charging speed of this new charger.
I’ve always been impressed with Anker’s quality. Their devices are and cables are rugged and stand up over time. You can probably get some cheaper alternatives, but I don’t want to have to worry at all about creating a fire hazard because I’m saving a few dollars on a charger.

Reviewed in the United States on October 24, 2021

Would buy again or a single port charger.
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...
