Lot of the bad (not necessarily cheap!) cables use either completely inadequate wire gauges, with only a few strands of copper - or don't use copper wire at all but copper coated aluminium (CCA) wire instead. Which is a lot cheaper compared to copper - and also much worse conductor. My bet is that the "seat heater" cable is actually CCA and not copper at all.

It has to do with that voltage drop! I found this out when experimenting with solar panels with direct USB output. Things like cell phones are "smart", they slowly ramp up the power draw while watching the voltage. Once the voltage drops too much, they stick there. If the voltage drops any time during charging, they assume a fault condition and default to a "safe" low power state. Good ones will then ramp back up after a delay, but bad ones are stuck. Some other "dumb" devices do similar, but they only have two levels, high port or low power.

Amazing video as usual! I only have one small note: you can't just simply multiply/divide to get a resistance/meter value, because - as you mentioned it - a lot depends on the connectors too. So x length of cable will not necessarily have double resistance compared to x/2 with the same internals and connectors, because depending on the quality, the connectors might give a higher fraction of the resistance. For example if you have a 2x resistance, where 1x is from the 2 connectors, and 1x from the cable, by having double length, you will have just 3x resistance. But that's all theoretical, we could get more accurate results only by fully disassembling them, and measuring separately the connector and the cable.

​@@AtlantisArch It's a good idea to have a chip, never disagreed with that. Just saying that there are 3 components: load, power supply, cable. Ideally the system could measure the cable resistance. But, a chip is better than blindly trying to draw 5 amps. The loads don't usually seem to slam up to full current, anyway; they ramp up and monitor voltage. So then the bad situation is a 5A chip cable, an incautious load, and a power supply that goes from full voltage to failure without any voltage reduction as a signal. House wiring has overcurrent protection. Many people assume that prevents a fire when putting a 15A load on a 18awg cord set. There should be a fuse in any cord that can't take the full 15 (or 20A, these days) that the outlet will provide.

The Silicon Chip magazine published a design and made a kit for a usb cable tester about a year ago. This passes up to 1A through the power lines of the cable and measures the voltage drop across it as well as checking what pins are connected to which. I don't have any high power usb c devices, but it has been good for creating a system of tagging known good and bad cables around the home so I know they are reliable / charging only or can do higher currents.

E-Markers are part of the USB-PD (Power Delivery) standard, which is a separate standard from USB 2.x/3.x themselves. USB 3.x itself only supports a maximum current of 900 mA (500 mA for USB 2) and only if a device requests that much power. If a device requests nothing, it may only draw 150 mA (100 mA for USB 2) at most. If an USB power plug supports USB-BC (Battery Charging), again a separate standard, which only requires some resistors for detection, they can draw up to 1.5 A. Most plugs do support BC today and most devices still use it for charging (that's because in the EU supporting this standard is required by law for products to be sold there). Only if you need even more, you need to use USB-PD instead. When using PD, the cable must tell plug and device what it is capable of and the device must tell the plug what power it desires (5 V, 12 V, or 20 V and up to 5 A are supported). Starting with PD 3.1, also 28 V, 36 V, and 48 V are possible at 5 A, resulting in up to 240W power delivery.

The schematic that shows how they're measuring it shows it as 500mV drop *at 5V* supply. The text shown doesn't specify what voltage they're using which is kind of weird because the voltage drop should be linear with the supply voltage, but USB does use 5V as the base voltage except when specifically triggered into a higher voltage so it make sense that this would be the default. So I expect pretty much all measurements are at 5V. If that's the requirement we can extrapolate that it correspond to a 2V drop at 20V, which only one cable exceeded and two got somewhat close (~1.5V) and 10 was well below the limit.

If i were buying such a cable i would get the cheapest one cause the more expensive ones isn't going to be any different in terms of longevity.

I believe part of the reason why some of those cables are over the expected voltage drop is because _you are misreading the USB spec._ The spec specifies a maximum of 500mV drop *for the Vbus line,* but it also allows *250mV drop for GND.* Measured together as a round-trip voltage drop (as your approach based on input/output voltage does) that means an allowed maximum of *750mV for the cable as a whole.* So cables G and L actually do appear to pass as well (and C and J are within the same "extra" range for measurement error which you afforded to cable F in your own analysis).

Beware, do not trust people talking about Watts without mentioning the applied Voltage when testing conductors. Amperage is the Industry standard for that. It makes no sense, especially since USB C cables are used with Voltages from 5 to 20 Volts like for Dell laptops. Watts = VoltsxAmps! The proper way to describe the this is using Amps, because the Voltage can be ignored using Amps. That is why fuses and cables are rated in Amps not Watts, a 15Amp breaker will trigger at 15Amp 10Volt =150W, 100Volt = 1,500W or 1,000 Volt = 15,000W. . Halfass education

The longer the wire the more resistance. It is the same reason Ethernet should be ran no more than 90 meters. I am not saying you can't get away with a little bit longer but don't be surprised if you have seemingly inexplicable reliability issues. Even a shorter cable can cause issues if it is broken anywhere or even not properly terminated. Or even just inferior cable may cause it too. I at least make sure to get mine from a place that sells some sort of branded one and not generic. In all fairness though, the generic ones are from a brand too. It is just not marked on them. My next upgrade as far as USB goes will be Thunderbolt 3 or better which is compatible with USB devices. You just won't get the Thunderbolt devices to work on a USB port. I am not sure if the new USB 4 is compatible both ways or not but it may be worth it once prices start to plummet if the scalpers don't prevent it.

What annoys me most with USB-C cables so far is mostly not the quality of the cables, but the plugs. I have a whole bunch of cables around which will simply not seat into the socket firmly any more and even if part of the cable hangs of the table, it's own weight is enough to lose the connection and stop charging. On that regard, the cable that actually came with my phone seems to hold up the best so far. But also let's be fair, i rarely opted for the more expensive cables, so I am not actually too surprised as well.

My current laptop has Thunderbolt 4 which apparently requires it to be able to charge via USB-C, but mine doesn't. Turns out that only counts if the laptop's normal charger is 100W or less.

Absolutely don't discount companies that follow the USB spec though. There are mechanical things that go into that too. Loose USB ports?

Hello, i test usb-c cables all day, we order them from china and test them if its okay to sell in europe like the voltage drop, durability etc. Its true that most of the cables are not made from pure copper its allways a mix. or CCA copper coated aluminium. Sometimes we cant even identify whats its made from. With the rising power the biggest problem are the connectors and things between them, allways check if theres any dust or liquid (resistance) before charging because thats where most problems come from, devices and cables burned at the connectors.

Given that the total resistance would be Rconn + Rwire + Rconn, it might be worthwhile trying to organize the cables by length to hopefully compare like for like with only the wire length affecting the comparison in a subgroup. Granted not all connector resistances are equal but I suspect the cable gauge/quality will be the biggest differentiator. You could measure temperature at the junction to see if certain cables heat up more or less at the connector.

Wire gauge is very important in both electronics and electricity. The smaller the gauge the less current it can handle. So it is best up go with a larger gauge of wire. In electronics it helps to reduce heat, in electricity it help in voltage drop. But anytime you use too small a gauge of wire for the amount of current passing through it the more heat it will generated and will also increase the chances of a fire. Ideally usb power cables should use 18-20 gauge wire but tend to use much smaller like 26 or 28 gauge wire, some even smaller.

Many people will want to use the same cable to charge and transfer data, so testing both is kind of important. I have a bunch of Anker cables only to find out they were USB 2.0 and not 3.0 / 3.1 speeds. This is annoying when my phone supports 3.1 but the cable only transfers 2.0. Now, I will admit, it was my fault for not doing more research and missing it said USB 2.0. I would have gone with USB 3.1 if I had seen it. However, these companies expect people to either not notice or know the difference in speeds, so sell lower quality cables than they should. I do plan to get a 3.0 to 3.1 cable, even if it isn't Anker because transfer speed matters more to me than charging (since all these cables are fast-charge anyway).

As it would probably be fair goo say a company particularly a smaller company would use thinner or cheaper components for shorter cables as the length of the wire may not require or make financial sense to do so. Again too confirm it may be that the longer cables could be identical apart from the length. But saying all this thank you for your experiments and results, it was still informative and appreciated.
