Will be OK to use charger listed below for Kontrol S88 mk3 ?

I use a Dell (3rd party) laptop 20V 3.25A 65W charger on my s88 mk3 and it works fine.

back of mine (pic below) shows similar to yours although mine doesn’t show wattage (easy to work out)

As far as amps and wattage is concerned, a device will only draw what it needs, my charger is saying, if needed it can go up to 65 watts

There’s various USB standards, apart from USB-PD (which is what mine and the one you’re looking at are), all the other USB specs are 5V. USB-PD can support up to 20V, 5A, 100W. The USB-PD also states it HAS to also support 5V, 9V and 15V. Many also support 12V but that’s not part of the standard.

Wattage is simply voltage multiplied by amps. Hence:

5V at 1.5A will draw 7.5W

5V at 3A will draw 15W

20V at 5A will draw 100W

So if a device is using 5V and 1.5A, it will draw 7.5W, doesn’t matter how many watts the power supply can deliver, that’s how many watts are needed.

Likewise if a 5V device only wants 1.5A, doesn’t matter if the power supply is 3A, 1.5A is all it will use.

Think about your wall socket, in UK it’s 13A. When you plug in say a phone charger, a router, a games console etc it doesn’t draw anything like 13A, but plug in a 3000W kettle, it will use 12.5 amps ( to find amps it’s watts divided by volts, so 3000w / 240v in Uk)

The multiple voltages are the different USB-PD "profiles" that @Ojustaboo mentioned. It's really just to let you know if you want to charge something super fast it can go up to 20 volts @ 30 watts.

My laptop for example needs 65 watts to charge while it's powered on. So knowing that, your charger wouldn't be a good fit for my laptop. But Ojustaboo's Dell charger would be a perfect match.

The short answer is that USB-PD will negotiate between the charger and device to be charge and picked whatever is the best that can be supported. Anker is a solid brand, but this is why you need to be cautious of cheap USB power supplies.

Yeah I'm still surprised given all the issues with compatibility, needing USB-C hubs etc... that NI just didn't toss in a power supply they knew would work.

I use this hub and it works great for my S61 MK3, using the factory single USB-C cable. It's a powered hub so it should work fine for the S88 as well. I bought it specifically because I have a Mac Studio, so I can plug it into the back USB-A 3.2 ports and still connect USB-C to the hub, and it's pretty cheap too. But there are definitely other USB hubs that will work.

Personally I like having a powered hub instead of a single dedicated "charger" for a device because hubs are more versatile. A 65 watt or even 30 watt power supply just for the S88 is pretty overkill.

I think it may be prohibitively expensive to try to figure out what power supplies work in which countries. By comparison, a USB-C plug is a USB-C plug, no matter in the world where you are.

Also, power supplies are little transformers and they're not clean and pure as the wind-driven snow to make. They require magnets, copper windings, management firmware, and lots of chemicals to make. There may even be an environment tax to sell such devices in some countries. There could be many reasons why manufacturers just don't include them anymore, but hassle factor is probably high on the list.

Yep, I THINK in the EU it was decided not to keep supplying new chargers with every product as most people had one or two already sitting in a drawer somewhere, and too many were being chucked away and ending in land fill.

Problem with the S series is that it uses USB-C and while many people might have USB-C, many others don’t, for instance my PC has no USB-C ports, my iPhone isn’t new enough to have USB-C, my iPad does have it, but I use that every day for charging.

From what I can gather, if I’ve understood correctly, if you have the mk3 88 note, you’re going to need a charger, this should at least be made very very clear on adverts (with a link to suitable chargers, while I might know what to get, many people wouldn’t have a clue) my new S88 sat there for a day while I waited for Amazon to deliver one as I was not made aware in advance that I needed one. not a happy start. I do think that if this is the case, they should have included one in the box, there’s too many dodgy ones on Amazon etc

Wow, a post from mid-February. But this still applies, so…

Companies can't win for losing these days, it seems. If you provide a power supply/charger with your new product, then you get accused of making the e-waste problem worse. You might as well be making AC adapters and just putting them out for the trash collection that goes to the landfill.

Or you DON'T provide a free power supply/charger with your new devices, and you get accused of being greedy.

In a way, it's cruel. Society keeps beating the donkey whether he listens or not.

My PC has two USB-C ports in the motherboard, and I built this one probably 4+ years ago. I also have an Asus Thunderbolt PCI-E card installed, which gives me two TB ports on the back, so that I can drive my UAD Thunderbolt audio interface.

But really, I find Thunderbolt to be more of a hassle than it is worth, so my next audio interface will be a USB version.

And I still have the iPhone 12, so I too still have the old "Lightning connector", but truth be told, I only use a cord when I'm in the car and want to use Apple Carplay's features. Charging the phone at home is always done with wireless charging. I was planning to upgrade to the 15 last year when it was first announced, but then I got to thinking more about it, and I decided that this time, I could just go a whole 4 generations between upgrades.

At this rate, I could possibly decide to wait for the iPhone 17 to come out. I could then easily justify getting the battery service done on this old one (I think I'm at 85%), and maybe finally get around to replacing the cracked screen protector too, lol.

This iPhone 12 "Pro Max whatever-whatever" has certainly been durable. The main reasons I'd want to upgrade is for the camera advances and the switch to USB-C.
