A hill I will die on is that tech products should just stop bundling cables, for anything, with the possible exception of unit-specific power adapters. A while back I purchased a KVM switch - it came with 3 DP cables, which went straight into my e-waste box. I've also seen office fit-outs where mountains of cables that came with monitors went straight from factory to landfill because they were the wrong length.

I understand some of the reason it happens - it's not a great experience to buy a product and then be unable to start using it immediately because you don't have the right cables. And there are a lot of low-quality cables out there which might have the right connectors but not actually work - I bought at least 3 different 5m DP cables before I found one that reliably worked at 4K. But surely that can't justify the literal mountains of e-waste the practice creates.

Sadly I don't think it'll ever change without regulation.

> possible exception of unit-specific power adapters

No. Unit-specific power adapters should not exist. Either put a USB-C or a 120v/240v AC connector on the device, depending on power requirements. It's really not that hard.

Note: it must be connector, not a fixed cable. I.e. an IEC C8 or C14.

I agree in principle, but I think there has to be some room for exceptions here. Some portable devices like smartwatches are too space constrained for USB-C and some devices might use too much power for USB-PD but still be too small to include the power supply internally. Also, some of my synth gear uses a locking barrel connector, which I think is a better trade-off than a locking USB-C connector because it can be locked and unlocked faster.

Bundled power bricks are also much less likely to directly be e-wasted without being used.

This might apply to (most) IT devices. But there are devices that require 24 V, or 48 V, or any other voltage that USB-C can't supply, and that for various reasons (space, EMI, possibly even compliance with some safety regulation) can't contain an integrated power supply unit from 120/230 V mains. Of course this should be an exception and most consumer devices can definitely work with the regular voltages and currents that USB-C can supply.

It's a bit silly IMO, but USB PD EPR _can_ support 24v and 48v- for charging laptops, I believe. The day I see a server rack with a pair of USBCs plugged into it is a far day off I hope though.

[ale42]

Didn't know, thanks for the info... I still have to see a power supply capable of delivering those voltages on USB-C though. All the ones I've seen can output 5V, 12V and 19V.

Sounds like a job for Power-over-Ethernet :)

That's fine but it should be a standard for a entire class of products.

[ale42]

Totally agree. Using something like USB-PD that has voltage negotiation on the wire might increase the price of some appliances (especially those that have just minimal electronics inside), but a standard connector (like just a barrel jack?) would already be nice thing!

[yellowapple]

I'd add 8P8C for PoE to that list, but otherwise agreed.

A really bad one now is devices providing crappy power only usb micro cables, very often these will still have the 4 pin head. I've started instantly binning them to avoid situations where I need to transfer data and can only find these ones lying around

Printers stopped coming with a USB A-to-B cable many years ago. Who knew that the printer makers were in the right all along?

[xp84]

Yes, and I think they did that for relatively cynical reasons -- as a handout to the Best Buys of the world who would then be able to attach a 90% margin "Printer cable" at $29.95 to your $50 Black Friday special inkjet.

I suspect the reason why this didn't go on to become standard across all classes of device, is because since 2010 or so, the average or median margin on accessories has cratered thanks to Amazon Marketplace sellers. You could realistically end up needing to buy a Belkin $30 printer cable in 2005, unless you'd heard of Monoprice. Today by contrast if you just search Amazon for it, you'll have one for $4.94-$6.49 delivered within 2 days. If margins were still what they used to be on cables and stuff, I think you'd have a strong incentive for places like Amazon and Walmart to pressure suppliers to make cables a la carte (officially for environmental reasons, but also, for great profits, lol)

You won't die alone on that hill. I think it's a great thing that many phones no longer ship with chargers. The mild inconvenience of having to buy a separate charger should not outweigh the reduction amount of waste we produce with new chargers.

Brazil has made it illegal to sell a phone without a charger which IMO is a total step backwards. If anything, it should be illegal to not give the option to unbundle cables from the package.
