[240W SUPER FAST CHARGING] This type c to type c fast charging cable supports PD 3.0 and QC 3.0 fast charging, it charges your macbook pro and new iPhone 15/15 Plus/iPhone 15 Pro Max as fast as Apple official 240W cable; Fast charging gives you a quick and convenient way to recharge your devices up to 80 percent in 30 minutes, and data transfer speeds up to 480Mbps (1200 songs synced per minute).
That's BS because PD 3.0's max wattage is 100W.
I'd still like to see someone give it 12 amps to find out :)
It is the voltage that goes up, the cable remains 5A max. That's why a lot of these cheap cables just have the eMarker chip updated to include the new voltages.
It's a bit annoying to test 240W cables if you don't have a laptop that supports 240W PD. Just because the eMarker is coded to 240 or 250W, it doesn't mean the dodgy cable is suitable for that.
Wouldn’t 240w be unnecessarily high in resistance and renders it ineffective if you are using it on a 100w pd?
The power adapter and the device determine the voltage and the current to use when charging. If there is an E-Marker chip inside, then the device will take the data into consideration. Also, most devices start with 5V and negotiate with the USB-C charger to ramp up the voltage and current.
Better quality wires need to be used for 240W and a E-Marker chip must be present. However, most people don't have ways to test / check the E-Marker. These cables can be dodgy. I bought a cheap USB-C Gen 2x2 cable (mainly for data) that's rated 100W on the packaging, but the E-Marker chip is coded to 240W. Would you trust such cable for power delivery?

That’s what I was referring to, not so much to do with the quality but the capacity of the cable needs to be higher, which means thicker cables. I have noticed the cable that comes with my 757 power bank heats up on 65w power draw, which kind of made sense as it only draws 22.5w charging, 65w therefore overloads the cable. It is then annoying to have to switch cables because it’s the same port to charge and discharge. Guess I could sacrifice some efficiency for convenience and use 100w cables everywhere.
The e-marker is an interesting component, I didn’t know about it, thanks for sharing. The only way to know if a cable is made to handle the wattage is to test how hot it gets me thinks, without professional equipment. 240w is a massive overkill or a marketing gimmick.
Dodgy 60W cables have much inferior efficiency / higher power loss. It still cannot compare to a dodgy charger (even worse).

Sorry to be blunt, that's because the cable provided by a lot of power banks (especially cost effective ones) are lousy. Original Apple lightning cable, even the USB-A, doesn't heat up. Cheap $2 cable heats up even with less than 10W charging. Cost cutting / cutting corner.
I wouldn't trust these el cheapo cables at 60W so rated 240W…. I am cynical about the claim. At 2m, most people can't tell if all they do is connect to the devices. The devices will still accommodate, but some of the smarter devices know it is a lousy cable. Put it through a meter, and you can tell the difference.
Ahhh, the Lisen al Gaib of cables.
Is this a genuine LISEN?
