C5 Usb Cable 240 Watt safe?

Hi,
I just purchased a usb to usb cable for my C5. It is a 240 watt usb cable. After the purchase i read online that this may damage the device. I also read that it’s ok. 2 conflicting points that both sides make are this: 1) Usb cables should have an e chip that communicates with the device and regulates the power being passed. 2)The camp that says it’s ok states devices control the amount of power coming into the device.

I’m overseas and the majority of cables here are cheap Chinese products. I’ve gone through 2 cables for my phone and laptop that stopped working after 2 months of use.

I do not want to damage my C5.

What are everyone’s thoughts on this am I safe to use a 240W? Even if the cable dies I am ok with it but I want to avoid it frying my C5. The article I read is that cheap cables exclude the e chip that regulates power going into device to cut costs and this is why it’s dangerous. Is this true? If so Bob mentioned the C5 regulates the power to 5 watts regardless so will the c5 protect itself?

thanks in advance

I suggest just using a standard, inexpensive USB cable. If more complex and expensive cables are designed and built properly (I have no way of knowing this in each individual case), they should limit their voltage to 5.0 volts (basic USB standard) unless the receiving device communicates a higher voltage requirement, so there should be no problem because micro-pulse devices do not request higher voltages.

my suggestion: spend a few bucks on a simple, basic, good quality USB cable, not USB-C PD (power delivery), not high-wattage rated. It may work fine, bit it will not work better, faster, generate more power… nothing like that.
