Attempt purchasing for a USB-C cable and also you’ll little question be struck by the complicated disparities in cable pricing and efficiency claims. These are simply cables, proper? Can they actually be that totally different?
At PCWorld we’ve used our share of USB-C cables and may say with complete confidence that, no, not all of them are the identical. Huge variations can come up within the high quality of a cable’s development and the way it performs, whether or not you’re speaking about charging or transferring knowledge.
My hands-on analysis of quite a few cables — starting from the most important, most-recognizable model names to the most cost effective of a budget — has revealed some clear winners.
For my USB-C cable opinions, I don’t trawl shopper opinions like some “reviewers” — I buy the cables retail and take a look at each personally, inspecting how they’re bodily wired, the resistance, and the accuracy of the embedded eMarker (if it has one).

Ever since Apple stopped promoting our prime big-brand cable for charging, we’ve been searching for an appropriate alternative and we might have lastly discovered it with Belkin’s BoostCharge 240-watt charging cable.
This 6.6-foot, or 2-meter, cable helps the very best USB Energy Supply cost price, comes from a acknowledged big-brand, and is identical value as Apple’s 100-watt cable that used to promote for $19.99 all day.
What occurred to Apple’s 100-watt charging cable? In step with up to date USB energy supply specs, which strikes the bar from 100 watts to 240 watts for quicker cost charges, Apple dumped the 100-watt 6.6-foot cable for a brand new 240-watt cable and *cough* elevated the worth from $19.99 to $29.99.
The excellent news is the Belkin BoostCharge 240-watt charging cable is a worthy different to Apple’s providing.
Internally, the cable is nearly on par with the Apple cable for cable resistance. That’s factor as a result of Apple’s cables are literally internally constructed fairly properly in our expertise. It’s the skin of Apple cables that has a status for falling aside and fraying.
The BoostCharge offers us extra confidence than Apple with its nice braiding, beefy overmolding and Belkin’s boast that the cable has been examined to greater than 30,000 bends.
The BoostCharge additionally options twin eMarker chips, which assist over-temperature safety. With 240-watt cost charges, that final function is especially necessary because the BoostCharge can detect if it’s overheating and sign the gadgets to pause till it has cooled down sufficient.
The largest bummer is the shortage of wiring to assist video output or precise high-speed knowledge transfers. The BoostCharge is mainly a plain-Jane charging cable supporting 480MBps switch charges (vs. 10Gbps or 20Gbps).
That’s wonderful although, as a result of most individuals are merely charging a laptop computer, pill, or telephone, and don’t want all of these options nor the majority (knowledge cables are usually a lot thicker because of the further wiring). We truly suggest that most individuals purchase a fundamental charging cable for the each day abuse of plugging and unplugging gadgets, and, if obligatory, reserving a shorter and higher-capability cable strictly for transferring chores. This could make the pricier quick knowledge and video cable final far longer.
Certain, the Belkin is $20 and maybe not the most effective worth, however for somebody searching for the nice and cozy embrace of a giant model to make them really feel higher, we predict the BoostCharge cable is an efficient choose. The TLDR is when you would have purchased an Apple cable however you’re balking at $29 for the equal — choose up the Belkin BoostCharge as an alternative.

How PCWorld exams USB-C cables
We bought retail USB-C cables for this roundup. We bodily measured and weighed every cable and examined every connector. A correct USB-C cable ought to use a one-piece shell quite than a folded shell with a visual seam in it. Not one of the cables we bought used the lower-strength folded shells.
We do need to level out that weight does are inclined to matter. All cables are primarily tiny metallic wire strands sure along with insulation. Certain, the connector, housing, braiding, and outer shell all components in its weight, however lighter-duty cables actually have fewer wires and are far lighter. For instance, the Cable Issues high-performance USB4 cable is 32-inches lengthy and weighs greater than the Amazon Fundamentals low-performance USB 2.0 cable, which is greater than twice as lengthy.
That’s not at all times higher although, as a cable with extra wires which are a heavier gauge—or thicker—are much less pliable and in addition take up more room in your bag.
You’d suppose you possibly can inform whether or not a cable is USB-C 2.0 by trying on the wires within the connector however that’s not the case. Some cables use connectors with pins that aren’t hooked as much as something.
For instance, a USB-C cable that’s wonderful for charging however a canine in knowledge switch will present up as being wired just for USB-C 2.0, as you possibly can see under by the inexperienced LEDs. The “CC” LED signifies the Cable Configuration channel is wired up accurately.
A full-featured USB-C cable has further wires to hold higher-speed knowledge and the USB Cable Checker 2.0 exhibits this Cable Issues USB 4 cable within the image under with the right wiring all out there. The small LED show additionally tells us that the cable has an ID e-Marker chip, the shell is correctly grounded to the cable, and it does a fast resistance take a look at too. The cable tester additionally checks to see if the steel shell of the cable is grounded to the bottom wire of the cable, which is required by spec. Each cable right here was correctly grounded.
Resistance is futile
The resistance examine from our cable checker is fast and soiled, so we augmented that by additionally measuring the resistance of the cable’s floor wire and vbus wire utilizing a milli-ohm meter related by way of a pair of USB-C breakout boards. The breakout boards at each ends add about 30 mohms to the whole. By spec, a USB-C cable shouldn’t exceed 83 mohms on the bottom wires and 167 mohms on the voltage bus.
Lots of the cables we examined have been inside spec or shut sufficient that it didn’t matter, since there’s seemingly much more resistance we’re not capable of account for with our methodology. We undoubtedly might inform which cables used heavier-gauge or thick wires with much less resistance to limit the circulate of electrical energy, and which of them cheaped out.

This Cable Issues USB 4 cable has all of the options you need for transferring knowledge or connecting your monitor.
What did the e-Marker say?
Since every of the extra superior cables carries an e-Marker that tells the pc what the cable can do, we famous that and the validity of the e-Marker’s claims. All however one of many cables met these claims, however the one which was mistaken was manner, manner mistaken. It claimed USB 3.2 10Gbps switch speeds and a 1-meter size, when it actually didn’t have the wires for the quicker switch speeds and was truly 2 meters lengthy.

Some USB-C cables function a chip or e-Marker that incorporates data the system reads. This two meter cable’s e-Marker is wrong.
We then checked out how briskly the cable would cost and switch knowledge, and whether or not it supported an alternate mode to run a monitor, utilizing real-world {hardware}.
For charging speeds we recorded the utmost wattage at which the cable might cost an Asus ROG Strix 15 gaming laptop computer over its USB-C port utilizing USB-Energy Supply with an Aukey 100 watt USB-PD charger because the supply whereas the laptop computer was below load. USB-PD at this time is restricted to 100 watts (with a 240-watt spec on the best way). Any USB-C to USB-C cable ought to deal with 3 amps at 20 volts, or 60 watts. All the USB-C to USB-C cables fell into the usual 60-watt or 100-watt camps.
We didn’t take a look at the temperature of every cable’s housing, however we did take a look at the most cost effective cable by operating it at 5 amps and 20 volts for an hour. The housing heated up by 50 levels Fahrenheit, and the cable itself grew to become comparatively heat (see the thermal picture under). Not superb, however it did this with out failure. We subjected different cables to two-hour masses with out failure, as properly.
For one closing cost take a look at, we tasked every cable with a 20 volt, 3 amp and 20 volt 5 amp load (for the 5-amp rated cables) and measured the voltage delivered on the finish of the cable utilizing our CT-3 meter.
The cables with the thinnest-gauge wires add extra resistance, which in flip reduces the voltage delivered to your laptop computer, pill, or telephone.

The thinner the wires utilized in a cable, the higher the resistance, and the higher the warmth as you possibly can see from this thermal picture of a $5 6.6-foot USB cable carrying a 5 amp, 20 volt, 100-watt load for one hour.
For knowledge switch, we measured the pace utilizing Crystal Disk Mark 8 whereas plugged into the USB-C/Thunderbolt 4 port of an MSI Status 14 Evo laptop computer. For the reason that cables can be used to switch knowledge from a Thunderbolt storage drive, we measured how briskly that occurred utilizing a high-speed SSD-based SanDisk Skilled Thunderbolt G-Drive. We discovered three switch modes among the many cables examined: Thunderbolt 20Gbps efficiency, Thunderbolt 40Gbps efficiency, or zero efficiency as a result of the cable wouldn’t work in any respect with a Thunderbolt drive.

Fundamental USB-C charging cables is not going to allow superior drives resembling this G-Drive Thunderbolt 3-based SSD, regardless of the USB-C plug becoming.
Our final take a look at checked out every cable’s functionality operating an Asus ROG Strix 17.3-inch moveable gaming monitor. The monitor is a high-performance gaming monitor with a decision of 1920×1080 and refresh price of 240Hz—which is mainly the identical bandwidth necessities of an ordinary 4K 60Hz show.

It’s mainly the most typical sort of cable for electronics at this time and due to its common and open design it has quickly changed all different rivals together with Apple’s Lightning in addition to older USB cables. It’s enchantment is the reversible nature so that you not need to search for alignment. With its potential to deal with 240 watts now, USB-C to USB-C cables will seemingly start changing different proprietary cables as properly.
What’s the distinction between a Kind A and Kind C cable?
There are a couple of key variations between the 2. A USB-C to USB-A cable has an oblong connector on aspect with 4- to 9-pins in it. As you recognize from attempting to plug a mouse into your PC, it solely suits in a method and also you normally by no means get it proper the primary time.

With most new telephone chargers going to USB Kind C, you’re most likely going to normally need a Kind C to Kind C cable.
Do you have to purchase a USB-A to USB-C or USB-C to USB-C cable?
The suitable reply is determined by what you need to plug the system and cable into. If you’re charging your Galaxy S24 Extremely or iPhone 15 right into a charger utilizing a USB-A port, then clearly, you’ll need to purchase a USB-A to -C cable.
When you’re questioning what the capabilities are between a USB-A to -C versus a USB-C to -C cable, that largely is determined by the cable.
In pure capabilities, a USB-C to -C can probably cost as much as 240 watts and switch knowledge at as much as 40Gbps (and better finally with USB4). These are all issues even the most effective USB-A to -C cable can solely dream about.
The factor is, whereas a “full-featured” high-end USB-C to -C cable can do extra, most telephones can’t benefit from its options. For instance, it’s a must to have an iPhone 15 Professional, iPhone 15 Professional Max, or a high-end Android telephone such because the Samsung Galaxy S24 Extremely or Google Pixel 8 Professional to have the ability to switch knowledge at 10Gbps. Most price range telephones and tablets switch knowledge over USB at a plodding 480Mbps even when you’ve got a USB-C to -C cable able to 40Gbps switch charges. And also you guessed it, if a telephone’s prime switch pace is simply 10Gbps, pairing it with a 40Gbps-capable USB-C to -C cable nonetheless limits you to 10Gbps switch speeds. The straightforward fact is that for knowledge switch, a USB-A to USB-C cable that helps USB 3.2 10Gbps or 20Gbps switch charges is greater than sufficient for most individuals.
The place it seemingly issues extra to pay for a USB-C to -C cable is charging pace. Exterior of proprietary fast-charging designs utilized by a couple of telephone makers resembling Huawei, Oppo, and One Plus, USB-A on even the latest iPhone and Galaxy usually prime out within the 15-watt to 20-watt vary. Utilizing a USB-C to -C cable and an acceptable USB-C charger will allow you to attain 30-watt cost charges or extra relying on the telephone.
We’d be remiss if we didn’t level out that regardless of USB-C charging usually outperforming USB-A — in actuality, you’re not giving up that a lot efficiency since most telephones don’t cost at their most cost charges more often than not.
TLDR: A USB-A to -C cable with assist for USB 10Gbps will work wonderful for almost all of quick telephones for knowledge switch however gained’t hit the upper cost charges you want.
Is USB-C the identical as USB PD?
The quick reply isn’t any. USB-C is the usual that defines the bodily “oval” reversible USB-C plug and connector and nothing extra. It doesn’t check with the underlying switch protocols resembling how briskly knowledge is transferred. A USB-C connector generally is a very sluggish 480Mbps “USB 2.0” or it may be the quickest 40Gbps USB4 or Thunderbolt 4.
USB PD, or USB Energy Supply, refers back to the superior charging capabilities over a USB-C a connector and cable. The latest USB Energy Supply 3.1 spec permits for charging as much as a formidable 240 watts, though we’ve but to see any laptops that assist it but.
Why gained’t my low-cost USB-C system cost over USB-C?
