Lots of cables not up to spec!

 

[Anubis]

yea saw this yesterday, not surprising

even the One+1 cable is not the correct spec

 

[Mopetar]

Kind of scary how many of them don't meet specifications or could potentially damage whatever they're connected to.

Wow. We need more reviewers like this guy. Pretty lol too that his very first review is of the Orange Box soundtrack from 2007.

So...all of those 3rd party lightning cables I buy are also questionable? Makes you wonder too about all of those micro sub cables out there.

I actually own a couple of those techmatte micro usb to usb c adapters they reference and have had no issues charging my Nexus 5X with it connected to a variety of different usb to micro usb cables.

To be fair he says it won't be compatible with the pixel, not sure why it'd be different from the 5X but I'd probably defer to an engineer who works on the product rather than some cheapo cable company. Maybe the pixel uses something that the phones don't and that is why the adapter works fine with the phone and not the pixel?

Anyways I noticed he reviewed the USB-A to C cables I first bought from NewLobo, and says they're out of spec. Pretty sure he's right as it charges my phone "rapidly" from my old HTC AC/DC plug which is supposed to be only 5V 1.5A. I'm almost tempted to rip apart the cable and put a current probe on it to see how much it really pulls, so far it hasn't caused a problem but it wouldn't surprise me if it sent this adapter to an early grave if I keep using it. I ended up ordering new cables anyways because the newlobo ones don't fit with my case, so I might experiment with it a bit.

From reading the comments on the Techmatte, I believe the Pixel draws a full 3A while the Nexus 5X/6P do not?

I also have a new lobo usb-a to c cable which also has been working fine for me but I also am using Anker Power IQ Car/Wall/Battery chargers. Don't know if that makes any difference.

I followed the Amazon review from this AndroidPolice comment. It appears to say that the 5X/6P does pull 3A when charging if it's told that the source is capable of providing that much amperage.

Thirdly, you seem to misunderstand the point of my review. You seem to be constantly trying to argue that the cables themselves are rated at 3A and can charge the Nexus 5X and 6P at the same speed as the stock OEM cables, but according to the USB Type C Specification, you SHOULD NOT be able to meet the same speed.

By setting the 3A resistor setting, you may cause damage to wall chargers, hubs, or PC USB ports that are NOT rated at 3A because the device will attempt to pull 3A and while the Type-A host on the other side may be ANYTHING made with a USB-A port since 1997.

The specification dictates that you MUST use a 56K pullup to identify as 'Default USB Power' source if you use a legacy cable in order to protect weaker chargers, hubs, and PCs that have been made in the last 18 years. Please read the USB Type C specification, the document named "USB Type-C Specification Release 1.1.pdf" Specifically section 4.5.3.2.4.

"The value of Rp shall indicate an
advertisement of Default USB Power (See Table 4-13), even though the cable itself can carry
3 A. This is because the cable has no knowledge of the capabilities of the power source, and
any higher current is negotiated via USB BC 1.2 or by proprietary means."

Using your bad USB cable, I have personally seen a high quality Anker charger in a brown out cycle continuously until I unplugged your cable and my Type C device charging from it.

By selling a cable that has a Type-A plug on one side but a resistor that should only be used when there is pure Type-C charging path (ie, C-C cable to a C port), you risk damaging people's older hardware with your out-of-spec cable.

Please fix your cables. Add a 56K ohm pullup instead of what you have now, and STOP claiming you can charge Nexus phones as fast as a C-C cable to the OEM charger.

Someone also made a spreadsheet organizing all this info on type C products

ps: It won't let me save a copy of the sheet to my drive, anyone know why?

I purchased one of the iOrange cables, it does not charge rapidly with my old chargers while the new lobo cables do. Pretty much lines up with what the guy was saying, it tries to pull more current than the charger is capable of, I definitely wouldn't trust and old AC adapter to last that long when it's maxing out it's power capacity all the time. The iOrange cable seems to charge really fast anyways so I don't mind that it's not charging "rapidly".
