The ad copy also mentions a 56k ohm pull-up resistor “for safety.” That last part confuses us because that’s only required on a USB-C to USB-A cable—not USB-C to USB-C.Despite this, we saw solid performance in both reaching 100-watt charge rates for a laptop, and very low resistance on its high-quality wires makes it our top pick for a 6-foot charging cable from a brand you haven’t heard of.And while it lacks wires to support USB 3.1 speeds, that makes the cable very pliable and lightweight. Like most brands we’ve never heard of, there’s confusing ad copy, with claims of just 5 volts at 3 amps (15 watts) and no mention of it supporting 20 volts at 5 amps (the 100 watts you need for a laptop). (Learn more in our guide on how to buy a USB-C cable on Amazon without losing your mind, and find out about how we tested these cables below our picks.)The Javex USB-C to USB-C cable came to our attention over its claim of having met the stringent UL 9990 testing standards, which involves Underwriters Laboratory buying random samples of the cable from stores and rigorously testing them for performance and consistency.As you can imagine, it’s probably not cheap to be in the program, especially when few are even aware of the value of a UL 9990 logo which could explain why Javex is no longer listed as part of the program but still claims UL9990 “materials” are used.Regardless, we do know that in our testing, the cable was top-notch in delivering higher voltage at both 60-watt and 100-watt loads. In doing so we were able to identify some clear winners to make your purchasing decision easier.We separated our picks into two groups: USB-C cables that are suitable for charging, and those that are suitable for both charging and fast data transfer, which essentially comes down to the difference between USB-C 2.0 and 3.1. So we bought 14 cables ranging from the biggest, most recognizable brand-names to the cheapest-looking cables around and put them through the wringer to test relative performance.
![]() ![]() But if performance and quality is your jam, the Cable Matters 6-foot USB-C cable will have you humming.Cable Matters USB3 Cable is but 2.6-foot so it lacks the appeal of long cables. At $20, it’s among the more expensive cables here. Those thicker gauge wires also mean you can’t roll up as easily or compactly as other cables, too.And no surprise, high performance and high quality mean it’s not cheap. The cable weighs almost 3.5 ounces, making it the the heaviest cable we tested outside of the 4-meter (13-foot) cable we looked at above. To hit 40Gbps, you’d have to step down to a shorter cable.The other cost of this quality is weight and pliability. That’s not a ding in our book because that’s the tradeoff of a 6-foot cable. Asus Tablet Charger Cord Full 40Gbps DataThis 6-foot cable features rubber sleeving and hefty wires that gives it a substantive feel without the stiffness you get from some cables.It's marked with Amazon Basics and a SuperSpeed logo so you're not going to mix up with the generic cables you have and the SuperSpeed logo tells you it's fast for data transfers.In our testing, we were able to able to push the limits of our USB 3.2 10Gbps SSD and could also drive our 240Hz 1080p panel. That makes the cable best suited to niche areas but it's fast nonetheless with excellent construction.There's not a lot to dislike about the Amazon Basics USB 3.1 Gen 1 USB-C cable. Compared to the Amazon Basics USB 3.1 USB-C cable, you'd only be paying $3.17 per foot.That Amazon cable can't match the Cable Matters USB4 in Thunderbolt performance but few need it. Looked at for dollar per foot, this $20 cable is about $8 per foot. That also translated into excellent USB 3.1 data transfer rates, monitor support and the only cable here capable of driving our Thunderbolt 3 SSD at a full 40Gbps data rates.If you're looking for high-performance in all things and don't mind the length, the Cable Matters USB4 cable is our pick.Its weaknesses are its stiff construction thanks to the higher-quality, thicker wires and construction Cable Matters uses and its price. We could even drive our high-performance Thunderbolt drive at 20Gbps transfer rates so way to sell yourself short Amazon.The only real disappointment with the cable is charging is limited to 3 amps which means it tops out at 60-watt charge rates. Except it does just fine since the alt-mode on USB-C just uses the wires included for the higher-speed USB 3.1 data transfers to run the monitor. Why not label it USB 10Gbps? Amazon is sticking to the rules which say a 10Gbps isn't supposed to work on a 6 foot cable.Also oddly, Amazon specifically claims there's "no alt-mode" support for this cable so driving a monitor won't work. And despite its USB 5Gbps rating, we could hit 10Gbps speeds anyway which says the cable's signal integrity is good despite its length. In capability though, this 8.5-inch cable is one of the better performers—a consequence of its short length. Why settle for something inferior? But we understand some will want to see which cables didn’t make the cut and why.The Dockcase USB-C to USB-C cable is the worst value here if you only judge a cable by length and price. With that said, this is a fine cable, but there are indeed ones with more capability too.Compared to our picks above, we wouldn’t advise purchasing any of the other USB-C cables we tested. In fact, that's the primary reason we didn't give the cable the nod for best brand-name cable pick.It does carry Amazon's name which has value to some, but at $19, it's hardly a steal. Wrench force bike pump instructionsThe company doesn’t mention it but that Thunderbolt 3 speed is limited to 20Gbps, not the full 40Gbps Thunderbolt 3 users expect, so take note.
