If you charge one device only, it can get to 65w, 45w+20w for 2 devices. The Anker webpage has conflicting information on this. But their manual confirms 65w max for one device.

Oh I see what you're saying now. 20 * 3.25 = 65 (V x A = W). Sorry, I wasn't familiar with how Watts was calculated so learned something from you today. Thanks!

The interesting bit is that Anker decided to make one of the most important specs of a power bank confusing. This should be its headline feature! Makes you question whether this power bank can in fact output 65W.

Well, there are other power banks that can most certainly output 60W and are often on sale for $30. So why would you buy one that may or may not be able to do hat.

A lot of laptops won't charge while powered on with 60W output, they need that extra 5W unfortunately.. So 65W does make a difference. My lenovo won't charge at all while it's on, if I put anything less than 65W into it.

Powered off it's a different story, anything will charge it.

There are 65W ones as well for $30. I've been using an INIU 65W one for over a year now. It has real life (not nominal!) power of c. 72Wh. It goes on sale for $30 once a month roughly. I have one, my GF has one, her sister has one. It's not as big a brand as Anker but just as good in my experience and according to reviews. There are a few reviews of it on YouTube showing real life capacity. That's how I picked it. INIU now has 100W and 140W versions as well that should be able to handle even gaming laptops.

The recent reviews on Amazon suggest that these might have a high failure rate.
I had this same model fail me. The only Anker product I've owned to do so.

it means either ports should give you 65w, only when you charge simultaneously charge on 2 ports then it splits 45w + 20w, a lot of reviews point it works fine on all laptops, 65w is the bare minimum for a laptop otherwise it reports as under voltage

I often charge my M1 Pro MBP on 30w. My wife's MBA and my son's Windows laptop comes with a 30w charger.

Perhaps SOME laptops require 65w to charge, though I've never personally encountered this.

Edit: googled a bit;
14/16" MBP require 30w,
13" MBP and 13/15" MBA require 20w.

Where do you see in the manual that it states that a single device gets 65w? I'm looking at the link you posted and don't see that information anywhere. On the Specifications page, I see "Total Output - 67.5w" but that doesn't mention a single device. I would expect to see something like "USB-C1 -65w" to confirm what you're saying.

Injust mine today, says right on the box usb c 1 65w for 1 device

This looks great, but not sure on how heavy it is & does build quality is good enough to keep it safe post day to day usage dings that are very common. just go by light weight onces under 10k mah to avoid drop dings/damage accident. So I feel if dropping it once will beak it just stay away no matter which brand makes it. Unless you actually have a use-case. 1 bad experience is enough to ruin all our confidence in these products nothing against any particular brand

Got mine in and can confirm the 65w output for one device. This thing is a lot bigger than my old 20k anker battery. Works great though.

For those who purchased this, how many charges ar you getting? I have been testing it on my pixel 9 pro that has a 4700 mAH battery and Im getting 3.2 charges when I plug it in around 18%. Wondering if it's the same, given it's 24000mAH, I was expecting at least 4 full charges....
