True, but irrelevant I believe. These are plug-in chargers, not battery packs and even when 'fully loaded' are not going to be drawing anywhere near the maximum current available from the mains supply, so it's not as if the additional power requirements of the display come at any detriment to its charging capability. Yes, the display is using power, but the additional cost of that is probably going to be less than $1 over a year.
And my father never wanted a smartphone. He had a basic £20 'dumb' mobile that stayed charge for weeks. Didn't need anything fancy.
I can read and I have seen what charging speed which port gives, but in reality the charging speeds are much lower than what they claim if a 2nd device is being charged.
I use $10 USB-C cables with LED displays on them showing charging rate with any charger (and I have a lot of chargers). Way cheaper to buy a few $10 cables (less on sale), than super-expensive charger with a display.
Classic example of because someone doesn't use the tech they think no one else does.
I would be concerned with the quality of those cables and am not surprised to read in the review summary:
Because you have no purpose for having precise charging data doesn't make it gimmicky. Do you ignore the battery charge indicator on a laptop or phone because you don't care about the percentage of battery left? Most people don't. I like knowing if my laptop is charging at full speed or if a particular charger is living up to it's specs. Without such indicators (I use charging cables with LED displays in them) I would have no idea. That's not a gimmick to me.
I probably have 20 of the cables of all lengths and 100W and 240W, and they are basically reading from an e-marker chip so whether they are 2W off or not, I cannot say (nor do I care if my laptop is charging at 88W or 90W). I've been buying these cables for a couple years and only one bad one (DOA and was replaced by seller). I know they are not a precise scientific measurement instrument, but it gives me a much better idea how much power a device is drawing and whether it's working right.
Please re-read my OP. I clearly stated that 17 people will think this tech is amazing.
That's great it has worked out for you but I'm not wasting my money on questionable design/quality. Also, calling a user an idiot is hardly fair since they're using those cables like any typical charging cable. It shouldn't matter which direction you plug in a charging cable when it's USBc on both ends. Let's say you plugged it in reverse and it shows 0 W, is it actually still charging the device? In other words, does it charge in either direction but only report in one direction? Or does it only charge and report in one direction. The fact I even have to ask makes me lose interest in this cable. Simple design isn't quite simple.
