Targus Extension Cable

(Disclaimer: this is the SAME EXACT cable as the Naztech, except the Naztech has better connectors and is cheaper. I'd recommend the Naztech over this. Same criticisms apply.) Naztech USB-C to USB-C Cable, Certified USB 3.1 SuperSpeed+ Supports 10Gbps Data Transfer & 100W/5A Power Delivery! 3ft. Compatible with all USB Type-C devices (New Macbook) This is Nathan K, a Google Top Contributor program volunteer (Nexus/Pixel Support Forums), and follower of Benson Leung doing independent USB-C verification and testing. I analyzed Targus's "USB3.1 Type-C to Type-C Cable Assembly Gen2 1M 5A" [Model ACC927USX]. This cable claims to be a USB-IF Certified rebrand of CE LINK's U3-CC-5A1M C01000-00413. Yet it has major errors that suggests it does NOT comply with the USB Type-C specification version 1.2. This is a paradox. However, since I have encountered bad "USB-IF Certified" cords before (like the j5Create JUCX03), I have to conclude this Targus is noncompliant -- but safe. THE GOOD: This cable claims to be USB-IF certified on the packaging, and in advertisements. The cables have individual "Lot number" stickers on the cable itself. The connenctors are plain. Upon inspecting the eMarker it is properly rated for 5A/100W. This cable passed SI and DCR tests on a Total Phase Advanced Cable Tester Level 2. THE BAD: Upon manual inspection of the eMarker fields, there are silly errors. The Product ID is blank. The CertStat (certification) field is blank. The Vconn field claims "Vconn (always) required" insted of "for Identification only". HW and FW fields are blank. The IR drop is comparable to 3A OEM cords, but still within 5A limits. Per-pin resistance is high. WHAT IT MEANS: As I cited with the Plugable cable, a PID of Zero will only become a problem if CE LINK make *any other* product with a PID of 0. The CertStat field being blank means some devices/peripherals may refuse to work with this cable since it is "not certified". Vconn being labeled as required means it will "waste" 25mW of battery power continuously. IN CONCLUSION: I'd advise against the Targus cable. It has mistakes compared to USB-IF Certified cables like the j5Create JUCX01, which I link below as the "gold standard".
