This is probably more power through USB-C than most devices can leverage, though that's perhaps more of a ding on the marketing rather than the device. Most high-power laptops will either top out at around 100W or are artificially capped to 100W when not using proprietary chargers - see the note below from Anker about Dell compatibility, for example. As another example, most MacBook Pro models typically max out around 100W power draw, but Apple sells their 140W charger for those MacBook Pro 16" users and this Anker charger represents an opportunity to replace that charger option at a solid discount.

Due to Dell's proprietary charging protocol, Dell XPS 15 (9500/9510), Dell Alienware X14, and Dell Mobile Precision Workstation 5570 can not be charged at full speed with this charger.
So ultimately the 140W rating is only possible for devices which use the new 28V profile, which isn't particularly common (28V/5A). More on that in a bit.

The support for Programmable Power Supply (PPS)is unsurprisingly solid, with 5-11V supported with up to 5A of current, meaning support for both 25W and 45W Super Fast Charging. Moving beyond traditional PPS, this charger also supports the Extended Power Range (EPR) with the aforementioned 28V profile as well as Adjustable Voltage Supply (AVS) - AVS being a sort of PPS stepped voltage support for the range from 15V-28V.

A teardown has been well-documented for this adapter:

One note from the manual is the low efficiency at a 10% load (around 68%, not atypical for many chargers/power supplies). Ultimately, this charger is targeted and optimized for those shopping the $100 Apple 140W adapter and is truly aimed at replacing that high-power laptop adapter.

Good luck!

sure would have been nice if they'd have provided a second port. Especially given all you just said about topping out at 100W for all intents and purposes. Another device could really have benefited from simultaneous charge .

Nice analysis. But how do I utilize the remaining 40W after I plug in my Macbook Pro? I wish it has another USB-C power so I can fully utilize the charger.

Yeah I don't know what the value in this really is. 140 Watts is a lot of power to only have one port. My MacBook Pro took 97 Watts I believe and I had it hooked up to a 65 watt charger via my monitor (Ben Q and LG) all the time and that was plenty to keep it from dying throughout even a rigorous graphics heavy work day. 140 Watts is good but having a second port to take that 40 watts would have made this a much better charger. This charger may work for a select few people but most people won't need it and can go with something cheaper that gets the job done.

I love Anker products in general, but this particular 140w model has a bad record, with many reviews saying it was DOA. I recommend the 140w chargers from IDMIX and Baseus, which are cheaper than the current Anker deal and have multiple ports.

To your key point: plenty of devices which can charge faster don't typically need to do so. Between two of my USB-C laptops one is rated for 65W and the other for 45W and yet I've regularly measured both to draw no more than about 20W while running and charging in normal use.

This charger is intended to be a cheaper alternative for those shipping Apple's 140W model; those with an alternate primary use case are much better served by most any other option.

Good luck!
Jon
