What's Difference Between 5A Cable and 3A Cable (PD Protocol)

If you wanna buy the tester of POWER-Z, you can visit our Amazon store:

Introduction
---------------------------------------------------------------
From 5W to 240W, we find the charging speed of electronic devices is faster and faster. But it's not easy for us to get the proper cable.
Even though the appearance looks similar, the performance is completely different.
For example, the charging cable can be divided into 5A (100W) and 3A (60W).
So, today, we gonna talk about what's the difference between them.

I bought a cheap 2M 5A PD usb-c cable and the manufacturer cheated and put a 5A emark chip in a thinner 3A cable and devices attempt to charge over 3A but fail due to the electrical properties of the cable being wrong. I left a review of the cable on Amazon alerting people to the fraud and Amazon deleted my review a few weeks after I posted it saying I was mistaken and the manufacturer was honest. I tested the cable with a cable tester it doesn't lie but Amazon doesn't care! I promptly cancelled my prime membership in response.

[@mikewolf5367]

A general rule of thumb is always be careful when buying cheap cables off Amazon. You can wind up frying your electronics that way. Personally I only buy first party like from Apple. Yeah it might be more expensive but the peace of mind is worth it.

[@user-nj2uu1tb8j]

You really showed Amazon huh.

Hey I know this won't likely be seen by you, but you've been doing an incredible job with this channel and I thank you for your hard work going over these chargers and power standards!

[@Mello2603]

Your video really helped me figure it out which cable I should buy. Thank you so much.

[@ChargerLAB]

Glad I could help

[@dogukancil5128]

Some devices using the Usb-c connector but not the PD protocol will not charge with a cable containing an e-marker chip as there is no voltage on the cable before the initial 5v negotiation. Vape pens are great examples of these, as these small devices rarely have spare room for PD circuitry.

[@PSM-IPADZ_OX]

Another great educational video ChargerLab and thanks. Great info about the amperage of the E-marker chip. However, it’s sad that a lot of producers of charging cables don’t put the specifications on their product labels so we are unable to determine the real life charging wattage unless we buy the cable and also a USB measuring device like that sold by your company. Higher price cables don’t necessarily guaranteed faster charging time or higher charging wattage. And we cannot cut our cables too. In the end, we can only get an assurance if we buy cables of any sort from reputable manufacturers. Or to keep following your fantastic video tear downs of chargers and cables ……. Keep up the good work …. Thumbs up 👍🏼

[@PavelShevchuk]

Can you please make a video explaining why some cheap devices with USB-C can only be charged via USB-A to USB-C cable, but not USB-C to USB-C cable? Now i have two of these (hair trimmer and helmet intercom) and i guess device manufacturer didn't include a chip that does PD negotiation, but would be interested in a more in-depth review of this issue. Thanks!

Info I needed, what is best cable for data transfer.

[@arianamirgholami9555]

One interesting thing is noticed between my 5A and 3A cables is that my phone (mi11ultra) with mi65watt gan charger doesn't charge with more than 27 watts so 8-9v 3A but with a 5A cable it goes to 45 watts so 9V 5A which makes sense but I wanted to point out that not all devices uses that 20V and are more limited but can benefit from higher amperage

[@aaast2549]

Bro i use 67w charger with my mi11t the phone can use 67w. When i charge with my 65w gan charger it says it only charge 55w why it cant charger 65w?

[@YouTubeviolatesmy1stamendment]

I didn't realize that tester could show the data speeds the cable supported I just ordered one of those now I've been looking for something that could tell that I also wanted one that could tell the protocols too but I didn't need that one as bad as the one that could tell the speed but since it does both I'm getting it

What about 6A and 10A cable ? Like OnePlus iqoo cables. Whats the difference between these . And why most after market type c cable limits at 5A . I have tried my OnePlus device it charges at 5A only with 100w after market cable . But with OnePlus cable it charges upto 8A.

I need an urgent reply ...... I have both 45W and 65 W adapter. Both charge my Samsung S24 Ultra with Super fast charging 2.0 (5A Cable)......65 W adapter came with My Laptop Book 4 but when I charge the cable along with this adapter cannot charge my phone with 2.0 charging, that means that cable is not 5A.......So all the time I need to carry 65 W adapter and both cables with me,,,,, My question is can I replace original Laptop cable with my 5A mobile 45W adapter cable? By doing this cause any damage to my Laptop?

Definitely yes and it is so safe no matter 100w 200w adaptor or future 1kw 😂 because usb-c pd can automatically regulate voltage and ampere and it's based on your device (receptor) as shown in the video usb-c can regulate voltage from 5v-20v and 3A/5A and more... Based on USB-c version or pps

I have a 2 meter cable that claims 100w 5A. Does that mean it's lying? I can charge my laptop fine with it (65W charger) it does not complain about slow charging. Also, my Mi10T Pro does not always go to "mi turbo charge" 33W with it, sometimes it says "quick charging" and it goes to 18W. Could that be because of a dirty port or the cable?

[@antonsrandomstuff]

Apple standard charging cable for Macbooks is 5A 2 meters. But it is noticeably thicker than other cables (twice thicker than lightning cable).

[@ChargerLAB]

We can still buy 5A cables over 2m, but that will be expensive. Therefore, most manufacturers will make it within 1m (cost-effective option)

[@dragosmoldovan990]

@@ChargerLAB that is what worries me, it was no expensive. It was around 6eur, branded Baseus

[@plasticdope]

@@dragosmoldovan990 in my experience Baseus is pretty good, just they (and many other Chinese brands) prefer to set their cables/chargers compatible with Apple products at first priority. You can find a $6 3m 100W cable from st like Essager, which works perfectly with a Macbook, but struggling to communicate with a Surface laptop. Cheap does not mean bad, just need to be suitable, and Apple :v

[@Naxxx.110]

I think they should rate the wires based on Watt & not current. Watt would be less confusing

[@plasticdope]

60W : 3A max, 100W: 5A

[@ChargerLAB]

I think that's what the USB-IF is prepare to do: kzbin.info/www/bejne/h2W6gmmKeauAfJI

[@n.shiina8798]

using wattage could be problematic to devices that uses high current. let's say a 3A cable labelled as 60W, a 60W device that uses 15V would overload the cable since the max. current is 4A. if you look up on AWG table, there's no power rating but current.

[@user-sq2uh3cd4p]

Nope, Rated wire based on Current is good, if rated on power (W) would be confusing, the thing is the maximum output voltage of USB-C is 20V
