Nice average charger. Maybe even above average.

The only thing that type of cable is good for is a laptop while the phone lies on the desk. Even an external battery doesn’t work well. You need at least a couple inches of cable to make it functional with an external battery and more than that to use with most desktop computers or using an outlet.

Well yes it can fill the battery very quickly because it only has to travel the short distance of that cable.

Shorter cable means shorter path for electrons to travel therefore faster charging, smart 😉😂

It would be funny if it actually worked like this in practice

That is some Apple shit right there. Careful , they may see this. “Our shortest cable ever” sell that shit to us for like 40 bucks easily.

Actually, in theory yes it does work. Current is equal to voltage divided by resistance (I=V/R). The higher the current, the faster the charge. The longer the charging cable, the more resistance that cable has and the lower the current is, resulting in a slower charge. Fun fact the wireless charging (mag safe) that Apple makes for the iPhone only comes with a built in cable that is of relatively short length and only available in that short length for this very reason. The mag safe uses induction charging which is very inefficient and requires a lot more amps to charge your phone. If the MagSafe charger had a longer wire, you would need more than the 20 watt charging block to power the charger due to the resistance in the longer wire.

I had a feeling someone would bring up Ohm’s law, and that’s why I said “in practice” and not “in theory”, because you are correct, in theory a shorter cable means less resistance means faster charging.

In practice, a 1m usb cable has less than 1 ohm resistance; I would imagine the difference in charge time between a 1cm cable and a 2m cable would be measured in seconds.

Also yeah, MagSafe is relatively inefficient for charging, but it is one of the most efficient methods of wireless charging, if not the most efficient (because alignment magnets).

A longer cable wouldn’t change much at all in this equation. You can test this yourself with a usb c extension cable (assuming it supports the necessary PD standards).

They work as well as a fully formed one, though (I’m told)

Whowoodathunk that shortening the cable makes the charging faster! Apple been robbing us under our noses all this time!

The longer the cable, the more voltage drop, not current drop. And yes, if the device pulls the same current that lower voltage will reduce the wattage slightly. (And charge speed is not current. It’s power: IxV) However, voltage drop in a cable that is of normal length isn’t going to be an issue, and putting a higher wattage brick behind it isn’t going to do squat.

If a 20W charger is used, the puck would still attempt to draw 15W of power because that’s the rated charging load. The brick isn’t going to shove more power into the device to make up for voltage drop. (And if it did, it would be as a result of higher current, which would also increase voltage drop further).

You decrease the effects of voltage drop by either increasing the conductor size or by raising the source voltage (and thereby decreasing current for the same load).

it’s like those micro usb cables that would come with cheap bluetooth accessories in the mid-late 2010s, except longer.

thursdayfern t1_j62rbzd wrote

Sure, but I didn’t say electricity flows through wires, I said it was a shorter path for electrons to travel.

Also I was joking, this is obviously not how electricity works, otherwise you totally would be able to charge faster this way.

I like that video a lot, but that guy primarily talks about electromagnetism and alternating current; neither of those are a factor in a lightning cable, or in his car battery/light bulb experiment. Those are both using direct current.

You guys are all wrong. The battery charge is the total energy (joules) stored in the battery. Joules = Watts x time. To shorten the charge time, the Watts must be significantly larger than they are now. This implies that either the voltage or the current must be larger too.
