StarTech 4m 13 ft USB C to USB A Cable, M/M, USB 2.0, USB-IF Certified, USB Typ USB2AC4M

Benson here again, continuing my reviews of USB Type C legacy cables. Today I am reviewing StarTech's "1m (3ft) USB-C to USB-A Cable M/M - USB 2.0 - USB Type C to USB Type A Cable - USB C to A Cable (USB2AC1M)"Let's talk about spec compliance. My test setup today include a Chromebook Pixel 2015, and a Chromium OS USB-PD Sniffer (codename Twinkie). Please check it out by searching google for "Chromium USB-PD Sniffer". This product is also available on Amazon here : I got a comment in one of my previous reviews that I should be testing with a 2.4A capable power supply to demonstrate that the cable is of good enough quality to sustain 2.4A charging, so for this review, I am using one of Apple's 1st party power adapters with a 5.2V, 2.4A charging capability, specifically Apple's 12W iPad charger.Running the ectool command on Pixel:localhost ~ # ectool --dev 1 usbpdpowerPort 0: SNK Charger Proprietary 4618mV / 2400mA, max 5000mV / 2400mA / 12000mWPort 1: SRCIn this case, the Pixel has negotiated up to 2.4A of charging through the StarTech cable to the Apple charger.Switching over to the USB PD sniffer, I'll run the "tw cc" command to get a voltage reading on both CC lines:> tw ccCC1 = 417 mV ; CC2 = 20 mVThe important number to look at here is CC1, which indicates a voltage of 417mV. If you refer to the USB Type-C Specification 1.1 Table 4-25.Look at the row labeled vRd-USB, which indicates the legal voltage values to read from the CC pin in order to be categorized as "Default USB Power". The range is Min : 0.25V Max : 0.61V. For this cable, I measured a value of 0.417V right in the middle of this range, indicating that yes, this cable has a 56k' resistor and is within spec for CC termination.One more twinky command :> tw vbusVBUS = 4702 mV ; -2451 mAThe vbus command here uses twinkie's built in current and voltage meter. It's confirmed that Pixel is charging at 2.4A.For a USB 2.0 High Speed data test, I’ve hooked my Nexus 5X to my Chromebook Pixel via the StarTech Type-A to Type-C cable to test large file transfer via MTP. It just works, no problem!For other more subjective judgements of this cable : The Type-C plug on this cable is the stamped variety, meaning it has a seam on one side of the cable. This is ok, but not as great as the deep-draw plugs we see on other cables (especially 1st party ones from Google and Apple). The cable has a black plastic tip. What's really nice about StarTech cable is that the length of the cable is super thin and flexible PVC. Despite being so thin and light and flexible, the cable is designed well enough to handle 2.4A charging.In conclusion, this is a fine cable for your Nexus 6P/5X to use with all of your older USB Type-A chargers, hubs, and PCs. It also works great with Chromebook Pixel 2015 and will work great on USB Type-C spec compliant devices to come!

I use this to charge Xbox Series X, PlayStation 5, and Nintendo Switch controllers. It works perfectly. No problems charging during play or while the systems are in sleep mode. I also use it on my cell phone by plugging it directly into a USB port on the electrical outlet. My phone charges from 0% to 100% in 2 hours while still powered on. Zero problems. Fantastic cable!

startech has always been a favorite of mine. I can't think of how many cables I've bought over the years for different uses. repeat customer for sure.

I bought this as a replacement cable for my Lumi II steno machine. This is the brand Stenograph sends out with its writers, so I figured to repurchase the same. I wanted a backup as my current one stopped working, but that was due to my own fault. I bought two so I don't have to panic about not having a way to connect my writer. The first one lasted me three years, and probably would've lasted longer if I didn't basically cut it in half.

It is difficult to find charging cables that are compatible with my Samsung tablets but this one seems to be. The cable itself is thick and well made. I think this is a winner.

This USB-C cable was touching a plastic tape dispenser and it melted. See photo. I'd avoid using this for anything except data -- unsafe fire risk for charging.

What can I say, I've bought at least a dozen StarTech cables over the past year or two and every single one is a high quality reliable piece of equipment.The materials are always high quality, the manufacturing is spot on and everything works exactly like it is supposed to month after month in normal use.

Bought this because Benson Leung reviewed it. Been using it and working as it should.

Câble de qualité exceptionnelle ! Pas de faux contact, reste bien branché dans ma voiture. Recommandé !

As always Startech constantly delivers a superb product!

Cavo scarso che ricava molto lentamente, deluso...

Câble qui fonctionne correctement, respecte la norme USB Type-C (cf le commentaire de Benson Leung sur Amazon.com). C'est important si vous souhaitez l'utiliser sur les appareils sensibles, comme la Nintendo Switch qui a eu des problèmes avec certains câbles non officiels ne respectant pas cette norme.Construction correcte, cependant le câble est assez fin.
