Product review: aLLreLi USB 3.1 Type C Charging Cable for Nexus 5X / 6P

This listing combines several products, my review is for aLLreLi Type C to USB charging cable. I am using this cable with Nexus 6p.

I have been following Benson Leung reviews of Type C cables for a number of weeks prior to buying Nexus 6p. Benson has pointed out that many cables, including this one, violate the USB 3.1 specification that states that the termination resistor that advertises the maximum available current has been set incorrectly at 10K which advertises 3A of current, the correct value should be 22K which advertises 1.5A of current. However many Type A USB chargers are rated at 2.5A and some as high as 3A which are safe to use with this cable. I tried using this cable with a number of different chargers and the Nexus 6p phone. All of the chargers were self limiting to their specified capabilities, i.e. if the charger port is labeled as 1.5A that's what it approximately delivered, and charger ports that were labeled as 2.4A delivered approximately 2.4A.

To identify the maximum draw of the phone, I charged it with depleted battery using Type-C to Type-C cable and a Type-C charger provided by Google. My Nexus 6P has never drawn more that 2.5A when charging from the Type-C Google provided charger. Charging with aLLerLi cable and my various chargers stayed under this number as well. So I feel that the aLLeLi cable is safe for use with the Nexus 6p and a QUALITY charger. I don't want to say that it's safe for all combinations of devices, laptops like the Chromebook Pixel and the Apple Macbook draw more current than a phone, and there may be badly made chargers that lack current limiting and might burn themselves out. However with a quality charger that's rated for higher currents this cable will charge faster than a USB 3.1 compliant cable.

Below are the details of my tests. All test were done keeping all conditions the same: same level of charge for the phone, same apps running, keeping the screen on so I can see the results.

1) Type C to Type C cable that came from Google in Nexus 6p package with the phone discharged to the level at which is does rapid charging to see maximum draw
The phone draws 2300 mAh, the status indicates that it is charging rapidly. The phone battery level is at 61% to 62%.

2) aLLreLi Type C to Type A cable with several wall charger. I am using a current monitor to see how much it draws and compare the results with the cable received from Google in Nexus 6p package
With the battery level at 76% to 78% the phone does not use rapid charging. With non-rapid charging both cables behave the same
- aLLreLi cable 1.32A, Google cable is 1.31A

3) aLLreLi and Google cable with several different car chargers. The phone battery is at 58%, at this level it uses rapid charging if possible.
- aLLreLi cable using Bolse 3 port charger, 2.4A port: 2.31A (charging rapidly), Google cable on the same port 1.73A (charging)
- aLLreLi cable using Bolse 3 port charger, 1.5A port: 1.76A (charging rapidly), Google calbe on the same port 1.52A (charging)
- aLLreLi cable using Bolse 2 port charger, 2.1A port: 2.13A (charging rapidly), Google cable on the same port 1.51A (charging)

Attached are images from my tests that show the results with both cables.

The aLLreLi cable is 40 inches long. The cable inserted without a problem on the phone with a silicone skin on.

I received this cable from aLLreLi for testing and review. Bottom line: aLLeLi cable is not USB 3.1 compliant and does behave differently from a USB 3.1 compliant cable provided by Google in "rapid charging" mode however I see no harmful effect on the phone with good quality self-limiting chargers and I am using this cable on regular basis.
