Stranded has higher resistance because the strands are longer due to being twisted, compared to the solid wire.

If you think the connectors don't matter... I don't know what to tell you. They are one of the main reasons why crap cables are crap.

While true, if you actually compare wires with the same size conductors you will find that there is in fact huge variation.

It's due to thinks like the number and size of strands, how they are wound, the type of conductor and its purity, and of course the USB connectors and the soldering play a huge part in it too.

Eh, nobody wants a chunky cable and connector to handle 240W (maximum USB C can supply), and these days it is certainly not cheaper that a buck regulator.

Copper isn't cheap and the conversion losses are going to be less than the losses to heat from lower voltages. The industry has responded with very high efficiency 50V capable converters.

Another advantage of USB PD is that with the PPS mode the device can be even smaller, featuring a lower power charger for non-PPS supplies, and using the PPS mode when available for higher power charging. None of these phones that charge at 50W+ have a 50W variable mode buck regulator in them.

The cabling situation isn't ideal. Hopefully it will improve. At least you can be fairly sure that most things will charge with any random cable though, just maybe not as fast as you would like. I use it to reduce the number of chargers I need to take with me on tips. I just bring one for the laptop, and plug everything else into its USB ports. If I need a quick charge I can plug that one charger directly into a device, but I mostly just do everything overnight.

There is at least one trifold on the market already... Xiaomi maybe, one of the Chinese brands.

Anyway, it sounds good in theory, you can have a nice big display but still fit it in your pocket. The main issue is that it's not got screens on both sides when folded, and they are the soft foldable type that can be scratched with your fingernail. Unless they do them all folding inwards, but then it gets even thicker and they will want another outer screen as well.

There are lots of USB C chargers that have a detachable mains cable. Anker make a few models, but there are lots of others. They tend to be in the higher power ranges.

It's great being able to travel with only one small charger now.

Even though the UK stupidly left the EU, we will benefit from this because nobody will bother making worse products for our market.

I look forward to everything being powered from USB C, with my own choice of cable length and jack (right angle in either direction, or straight), and the ability to replace them if I damage them.
