Apple has announced the new iPhone 15 series, which replaces the company’s longstanding Lightning connector with USB-C for the first time. We’ll update this guide soon to reflect this development Usb A To Usb C Cable
If you have a device with a USB-C port—such as most laptops, tablets, game consoles, or phones, including the latest iPhones—you need a cable to charge it and to transfer data to and from other devices. Unfortunately, when it comes to USB-C, even cables that look identical can behave very differently—for instance, a cable that charges your phone at top speed might be sluggish at transferring music files, or vice versa. We’ve tested dozens of cables and adapters to help you find the right ones for your needs without overspending.
A quick primer on USB specifications for those living in blissful oblivion: While ordinary USB-A ports are limited to just 12 watts of charging power, USB-C ports can provide 18 watts of fast-charging power to phones and, more rarely, up to 240 watts to laptops (depending on the cable and device you plug into them). Apple’s Lightning ports can use regular 12-watt charging with a USB-A cable and faster charging via USB-C. Micro-USB and Mini-USB can provide only regular charging regardless of a USB-A or USB-C connection. Each has different capabilities and limitations in charging power and speed (measured in watts, W) and data-transfer speed between devices (measured in megabits per second, Mbps, or gigabits per second, Gbps).
This 6.6-foot cable rated for 100 watts performs just as well as Apple’s MacBook Pro charging cable—for about half the price.
Why you might prefer it: The Cable Matters USB-C to USB-C Charging Cable is rated for 100 W charging, so it can recharge even large laptops such as the 16-inch MacBook Pro at full speed. At 6.6 feet, it’s as long as any cable we tested in this category (it also comes in a 3.3-foot length). It’s USB-IF certified—meaning that it meets a set of criteria designed by the USB Implementers Forum, a nonprofit corporation run by Apple, Intel, Microsoft, and other tech giants—and it has a one-year warranty backed by a company we trust. And although it performs just as well as Apple’s 6.6-foot and 3.3-foot MacBook Pro charging cables (which aren’t USB-IF certified), it costs half as much.
Flaws but not dealbreakers: This cable supports only USB 2.0 data-transfer speeds, so it’s not the best option for moving big files around. It’s also thicker and bulkier than many of our other picks, but that’s a fine trade-off for maximum charging power.
This cable is sold only in a bundle with a 60 W wall charger, but the set is a great deal if you happen to need both. It charges phones, tablets, and laptops at up to 60 W at top speeds, and it’s an ample 6.6 feet long. It comes only in black, though.
Why you might prefer it: The Nekteck USB-C to USB-C Cable with 60W USB GaN Charger is typically priced about the same as Apple’s comparable MacBook charging cable—and as a bonus, it’s packaged with our favorite wall charger. Either item would be a good value on its own, but the bundle is a steal. The 6.6-foot cable is long enough to reach most outlets from a desk or couch. Its housings are as sturdy as any we tested, and the main body of the cable is slim and flexible. It’s also USB-IF certified and backed by a one-year warranty.
Flaws but not dealbreakers: Like the rest of our picks in this category, this cable has sluggish USB 2.0 data-transfer rates. It can’t provide as much power as the 100 W Cable Matters version, but it had no trouble powering devices at up to 60 W in our testing.
This cable offers the same functions as our main pick in this category. It’s twice the price, but it has a lifetime warranty from a company we trust.

Why you might prefer it: Anker’s PowerLine II USB-C to USB-C 3.1 Gen 2 Cable is another great option if you want to transfer data quickly (10 Gbps) as well as charge phones, tablets, laptops, and other USB-C devices that require up to 100 W of power. It’s sturdy and well built, and it’s USB-IF certified. Plus, it comes with a handy Velcro fastener to keep your cable neatly coiled, and it has a lifetime warranty backed by a company we trust.
Flaws but not dealbreakers: Like any fully functioning USB 3.1 Gen 2 cable, this Anker cable is short (3 feet) and too thick and rigid to easily pack into a drawer or bag—though the included cable tie helps. It’s also twice the price of our main pick in this category, but it performed just as well in our testing, and the lifetime warranty and more streamlined housing design slightly outweigh the extra cost.
Few devices are Thunderbolt 3 capable, but if you need top data speeds (up to 40 Gbps) and 100 W charging, this cable is the best we’ve found.
Why you might prefer it: This cable could be considered the “professional” pick, likely to be overkill in most homes. Rated for 100 W charging, the Anker USB-C Thunderbolt 3 Cable can charge a 16-inch MacBook Pro or any high-powered laptop. It’s Thunderbolt 3 capable, so although it looks like any other USB-C–to–USB-C cable (aside from the Thunderbolt logo on each end), it can transfer data up to four times faster (40 Gbps) between supported devices. When you use it with non-Thunderbolt USB-C devices, it functions as a USB-C cable that supports 100 W charging and USB 3.1 Gen 2 data-transfer speeds. The housings attaching the plugs to the main body of the cable aren’t as robust as those of some other Anker cables, but they seem sturdy and roomy enough to let you get a firm grasp. Notably, this cable’s 18-month warranty is the best coverage length we’ve seen in this category, and that should give you plenty of time to test the cable out with your devices and decide whether it works properly for you.
Flaws but not dealbreakers: The Anker USB-C Thunderbolt 3 Cable is shorter than we’d like, but there’s a practical reason: Thunderbolt 3 cables longer than 1.6 feet do not support data transfer at full speed, unless you’re willing to pay a premium for an active cable. And since most people are likely to use this cable at their desktop—for example, to connect a laptop to a portable SSD right next to it—1.6 feet seems plenty long. This cable is also rather thick, but that’s true of all Thunderbolt 3 cables, since bulkier wiring is required for them to perform properly.
This cable is Apple certified, it has sturdy housings to withstand frequent plugging and unplugging, and it’s compact enough to fit in a purse or pocket.
Just as sturdy as the shorter version, this Apple-certified cable is plenty long enough to keep at your desk or on your bedside table.
Why you might prefer it: Compared with the USB-A chargers and cables that accompany most Apple devices, USB-C–to–Lightning cables allow you to charge most iPhones and iPads (excluding the newest models, which charge via USB-C) at much faster speeds when you pair them with a high-speed USB-C charger.
Although our equipment doesn’t let us test the internal capabilities of any USB-C–to–Lightning cables, we did perform a head-to-head comparison of numerous options certified under Apple’s MFi (Made for iPhone/iPad/iPod) program. We like the Anker PowerLine II USB-C to Lightning Cable (3 feet) best for on-the-go charging, and we prefer the Anker PowerLine II USB-C to Lightning Cable (6 feet) for keeping at your desk or nightstand.
Of prime importance, the Anker cables’ MFi-certified status means they meet Apple’s standards to ensure optimal performance with the company’s devices—from iPhones to Magic Trackpads—in terms of charging and data-transfer capabilities.
Although you can find unlicensed third-party options, we chose not to consider them; since such cables might not be fully compatible with Apple devices, you risk the cable fitting incorrectly or overheating and then damaging the cable, your device, or both.
Anker backs both of its cables with a lifetime warranty and its excellent customer support. The cables have a thick, rubber sheath encasing their innards, yet both of them—but especially the 3-foot version—remain flexible and compact enough to stow easily in a pocket or pouch. Plus, each one comes with a convenient hook-and-loop cable tie to keep your cable coiled and to prevent tangling.
Unlike on Apple’s cables, the plastic housings that join the metal connectors to the Anker PowerLine II cables seem sturdy and robust, built to withstand bending or fraying even with frequent use. Compared with most of the other cables we tested, these cables make a satisfying click when plugged into a USB-C port and have minimal wiggling, ensuring a solid connection.
Flaws but not dealbreakers: The official Apple cable comes in 3.3- and 6.6-foot versions, so Anker’s 3- and 6-foot cables are a bit shorter. But they’re still plenty long in most scenarios. And although Apple’s cables are thinner and less bulky than the Anker PowerLine II cables, so they’re more portable, the Apple cables are notoriously flimsy—and they don’t have anything like Anker’s handy hook-and-loop cable ties.
If you want a fast-charging Lightning cable that can reach across rooms (and survive an apocalypse), this one’s for you.
Why you might prefer it: The 3-meter Nomad USB-C to Lightning Cable is just as fast as any other cable we tested, plus it’s encased in the most rugged sheath of any we’ve seen. The housing is made of a thick, double-braided Kevlar that seems less likely to wear or snag than the more common nylon material. The cable’s plastic housings are sturdy, with little ridges along the collar for added flexibility. At nearly 10 feet, it’s also the longest cable we tested, allowing you to more easily reach faraway outlets (though it also comes in a 5-foot version). Like the Anker PowerLine II cables, the Nomad is MFi-certified to work with Apple devices. And although Nomad’s five-year warranty doesn’t match Anker’s lifetime warranty, the coverage period is longer than that of most cables we tested. Lastly, the rubber cable tie that comes with the Nomad is more robust than any we’ve seen, with thick ridges fastening it closed, keeping your cable securely coiled.
Flaws but not dealbreakers: Because this cable is longer and more robust than other cables we tested, it’s noticeably bulky if you try to stow it in a pocket or purse. But if you plan to keep it in one place for the most part, or if you have room to spare in your bag, the Nomad’s added bulk might not be too bothersome.
This 6-foot cable is solidly built and works great for charging USB-C devices on older sources with only USB-A ports. It transfers data slowly (USB 2.0) and supports only 15-watt charging.

Why you might prefer it: The Belkin Boost Charge USB-C to USB-A Cable is your best bet for charging a phone, tablet, or other small USB-C device on a USB-A port. Some of older wall chargers, car chargers, and laptops have only USB-A ports, so having at least one cable like this around can be useful. The Boost Charge cable isn’t as capable as most of our other picks, but we confirmed in our testing that it can charge devices at up to 15 W of power, which is the limit for this type of cable. The plastic housings felt pleasantly rounded and comfortable to grasp while we were plugging and unplugging, and they seemed firmly attached to the body. The cable itself is also thin and flexible, making it easy to coil up and stow in a bag or pocket. It’s 6.6 feet long, which is the perfect length to reach from an outlet to a bedside table or desk, though it also comes in a 3.3-foot version if you prefer a shorter cable. In addition, it’s USB-IF certified, backed by a two-year warranty, and priced at only $10 or so at this writing.
Flaws but not dealbreakers: The Boost Charge cable is limited to slow USB 2.0 data-transfer rates (up to 480 Mbps). But since most people will be using it only to charge small devices, that isn’t a huge deal.
Most people use USB-C–to–USB-A cables for charging only, but the Anker PowerLine II USB-C to USB-A 3.1 Gen 2 Cable offers fast data-transfer rates up to 10 Gbps in addition to a full 15 watts of charging power.
Why you might prefer it: The Anker PowerLine II USB-C to USB-A 3.1 Gen 2 Cable is something of a rarity, a USB-C–to–USB-A cable with fast data-transfer capabilities up to 10 Gbps. If you need a cable like that—to charge a USB-C phone on a laptop’s USB-A port and also transfer files between them, for example—this is the one to get. In our testing, it achieved full data-transfer speeds, and like our main pick in this category, it can charge small devices with up to 15 W of power. The body of the cable is pleasantly thin and flexible, and the housings on either end are made of a solid piece of plastic, a design that we’ve found makes housings last longer, without breaking, compared with designs using a rubber collar. This cable is USB-IF certified, and unlike some of our other favorite Anker cables, it’s backed by an impressive lifetime warranty.
Flaws but not dealbreakers: The biggest drawback of this cable is that it’s short—just 3 feet long—but that’s the longest a USB 3.1 Gen 2 cable can be without adding lots of extra bulk. And although it’s fairly inexpensive, it still costs a little more than the $10 Belkin.
The best USB-C–to–USB-A adapter we’ve found, this lets you connect a USB-A plug to a USB-C port with a short cable. It can carry up to 15 W of power and offers moderately fast data transfer up to 5 Gbps.
Why you might prefer it: The Amazon Basics USB Type-C to USB 3.1 Gen 1 Adapter is great if you’ve bought a laptop devoid of USB-A ports, such as a MacBook Pro, and don’t feel like immediately replacing every older cable and flash drive you own. The advantage of a cable over a nub is that it moves the connected USB-A cable or flash drive away from the computer a bit—about 6 inches in this case. That extra length and flexibility can make it easier to use certain accessories, especially those with wide plugs. This adapter is USB-IF certified, it performed well in our testing, and it supports USB 3.1 Gen 1 (another way of saying USB 3.0) data-transfer rates up to 5 Gbps. It can also carry up to 15 W of charging power, allowing you to charge small devices at top speed. Available for $10 at this writing, it’s also one of the least expensive models we tested.
Flaws but not dealbreakers: Amazon Basics’s adapter has the shortest warranty (one year) of any we tested. But we’ve had generally good experiences with the company’s customer service, and a year should give you enough time to decide if this adapter suits your needs.
We don’t recommend a three-in-one cable with Micro-USB, USB-C, and Lightning for everyday use, but it is handy for travel.
Why you might prefer it: A three-in-one cable is, essentially, a USB-A–to–Micro-USB cable with Lightning and USB-C adapters attached by short tethers. Although we don’t recommend using such a cable on a daily basis because it’s limited to slow charging and data speeds and the adapters can be a pain, we do think one can be handy for travel or as a backup you can throw in your desk drawer.
Of those we tried, the Anker PowerLine II 3-in-1 Cable was the clear winner. It’s MFi-certified, it got top marks in our power-draw and data-transfer tests (like every three-in-one cable we tested, it supports only USB 2.0 data speeds), and it seems well made. It’s a slim cable that’s easy to coil up and stow in a bag, and we found its adapters the easiest to plug and unplug—the other ones we tried were fussy and difficult to wrangle.
Flaws but not dealbreakers: In theory, having a three-in-one cable is a convenient, compact alternative to carrying around three individual cables. But in practice, we found all of them cumbersome to use—an inelegant method of addressing different standards and legacy connectors. But if you regularly use all three types (Micro-USB, USB-C, and Lightning) and hate carrying around three different cables, this is a decent option.
We wish its rubber adapter tethers were easier to maneuver and built more sturdily—we fear they might break after repeated use—but none of the models we tested impressed us in that regard. This cable’s slim, compact design and good overall performance make it the best of the worst.
The Amazon Basics USB Type-C to USB Type-C 3.1 Gen 1 Cable worked fine in our testing but had an F rating on Fakespot the last time we checked, and some reviewers say it stopped working after about a month and a half.
Although the Amazon Basics USB Type-C to USB Type-C 2.0 Cable performed similarly to our Cable Matters pick in power draw and data-transfer speeds, its plastic housings felt flimsier.
The Anker PowerLine III 60W USB-C to USB-C Cable and Anker PowerLine III 100W USB-C to USB-C Cable each cost twice as much as our current picks in this category, and neither cable is USB-IF certified. Even more perplexing, when we ran them through the Total Phase Advanced Cable Tester, it reported signal-integrity errors every time.
The Google USB-C to USB-C Cable (USB 2.0) is the standard-issue cable that ships with Google Pixel phones. It seems fine, but we didn’t test it since it costs so much more than other contenders.
Apple’s USB-C Charge Cable (2 m) was our former pick in this category, but it’s not USB-IF certified. Plus, our Cable Matters pick is about half the price and just as good.
Apple’s USB-C Charge Cable (1 m) is half the length and twice the price of our Cable Matters pick, and it’s not USB-IF certified. Although its slim design makes it more compact and portable than our pick, it feels notably underbuilt compared with the competition and has less reinforcement at the cuff.
The 2.3-foot J5create USB Type-C 3.1 to USB Type-C Coaxial Cable used to be our pick in this category, but it’s on the shorter side compared to other available options.
The Belkin Thunderbolt 3 Cable (100W) performed about as well as our Anker pick in our tests, and they’re both backed by two-year warranties, whereas the Anker cable’s coverage lasts for 18 months. Anker’s cable is more widely available, though, and the matte finish of its housings makes it look and feel more luxe than the Belkin models.
Although the Apple Thunderbolt 3 (USB-C) Cable performed no worse than our Anker pick in our testing, it has a shorter warranty (one year) and costs more. Plus, any Thunderbolt 3 cable longer than about 1.6 feet (like this one, which is 2.6 feet) can’t provide top data-transfer speeds.
Although the Belkin Boost Charge USB-C Cable with Lightning Connector as roughly on a par with our 3-foot Anker pick in our testing, its housings were not as sturdy or easy to grasp as the Anker’s.
The Nomad USB-C to Lightning Cable with Kevlar (1.5 m) is just as rugged as the 3-meter (10-foot) version. But at this shorter length, it’s not as useful for reaching faraway outlets—and it’s too bulky to be of much use for on-the-go charging.
The Anker PowerLine+ II Lightning Cable (3 feet) and Anker PowerLine+ II Lightning Cable (6 feet) are pretty much identical to our PowerLine II picks, except they have double-braided nylon sheaths instead of rubber. The different sheath didn’t seem to add much to performance, and these models cost a few dollars more, which is why we didn’t name them as picks. But you should get one of these if you prefer a fabric sheath and don’t want the added length or bulk of our Nomad pick.
The Amazon Basics USB Type-C to USB-A 2.0 Cable is similar to our Belkin pick in that it’s a good (6-foot) length, it’s USB-IF certified, it performed well in our power-draw tests, and it gets up to no more than USB 2.0 speeds. Unlike the Belkin, though, it has a short, one-year warranty (versus two years) and somewhat flimsier housings.
The Amazon Basics USB Type-C to USB-A Cable used to be a pick in this category, but it has worse housings than our Belkin pick and a measly 30-day warranty.
In our latest round of testing, we ousted our former pick in this section, the Anker PowerLine USB-C to USB 3.0 Cable (3 feet), for not being USB-IF certified. In contrast, our Belkin and Anker PowerLine II picks both have this certification and performed as well as or better than this cable in our testing.
The Anker PowerLine USB-C to USB 3.0 Cable (6 feet) is a nice length and has a great look and feel; it also achieved full USB 3.1 Gen 2 data transfer speeds (10 Gbps) in our testing. But in addition to not being USB-IF certified, this model fell short in our tests, as the Total Phase Advanced Cable Tester reported DC-resistance and signal-integrity errors.
The Anker PowerLine USB-C to USB 3.0 Cable (10 feet) was the longest cable we tested in this category. Unfortunately, it’s not USB-IF certified, it got up to only about 5 Gbps in our testing (USB 3.0 data-transfer speeds), and it had DC-resistance and signal-integrity errors when we ran it through the Total Phase Advanced Cable Tester. Also, due in part to its impressive length, it’s extremely bulky.
The Anker PowerLine+ USB-C to USB 3.0 Cable (3 feet) performed well in our tests, and its braided cable makes it a bit sturdier than both our Belkin and Anker PowerLine II picks. But it’s not USB-IF certified, and most people don’t need such a rugged design.
Similar to our Anker pick in this category, the Belkin USB-A to USB-C Charge Cable F2CU029bt1M-BLK offers USB 3.1 Gen 2 data-transfer capabilities and 15 W charging, and it’s 3.3 feet long and USB-IF certified. However, it costs more than the Anker version, it has worse housings, and it comes with a two-year warranty, whereas the Anker has a lifetime warranty.
The Belkin USB-A to USB-C Charge Cable is a former pick, but we found its housings inferior to those of our current Belkin pick. Also, its 90-day warranty is laughably short.
The build quality of the Google USB-C to USB-A Cable is really nice: It’s exceptionally thin, it has a strain-relief collar to help prevent breakage over time, and a built-in plastic clip keeps the cable coiled when you’re not using it. But it isn’t USB-IF certified, it gets the slowest possible (USB 2.0) data-transfer speeds, and it’s only 3.2 feet long.
The Monoprice Essentials USB Type-C to USB Type-A 3.1 Gen 2 Cable performed well in our tests. In addition, it’s USB-IF certified, it offers the improved data-transfer speeds of USB 3.1 Gen 2, it comes with a lifetime warranty, and it costs a fraction of the price of some of the other USB 3.1 Gen 2 cables we tested. However, it doesn’t have a particularly rugged or streamlined design, and it’s available to buy only on Monoprice’s own website, which charges shipping fees. If those drawbacks don’t bother you, though, it’s a good alternative to our Anker pick.
The StarTech USB 2.0 USB-C to USB-A Cable is probably the competitor most similar to our Belkin pick of those we tested: It’s 6 feet long, it’s USB-IF certified, it earned good marks in our power-draw tests, and it reaches only USB 2.0 speeds. But even though it costs about the same as the Belkin, it’s not as nice to look at and feels cheaper.
Nonda’s USB-C to USB-A 3.0 Adapter performed well, but its fat shape makes it difficult to fit two plugs into side-by-side ports. And Rankie’s USB-C to USB 3.0 Adapter felt cheaply built compared with the others we tested.
Anker’s USB-C to USB 3.1 Adapter isn’t USB-IF certified.
In our power-draw tests, the Jsaux USB Type C Adapter performed abysmally—2.3 watts, in contrast to the 7.4 watts we saw from the other models we tested. We also think the little built-in plastic loop and silver chain (designed to attach the adapter to a key ring) are impractical and tacky.
Like our Anker pick, the Nomad Universal Cable is MFi certified, and it passed all of our data-transfer and power-draw tests. At nearly 5 feet long, it’s 2 feet longer than Anker’s version, yet it’s still fairly compact. Its braided fabric sheath and rubber cable keeper are nice touches. But this cable’s plastic housings were the worst of any we tried—plugging and unplugging this cable felt like doing battle with an unyielding opponent. Plus, the Total Phase Advanced Cable Tester reported a DC-resistance error.
Before beginning our initial round of testing in 2015, we consulted with Nathan K., a volunteer with the Top Contributor (now called Product Experts) program at Google. He’s an independent tester who has worked with Benson Leung, a famed (in these circles) Google engineer who first brought to light potential issues with USB-C accessories that didn’t conform to USB-C specifications.
In our latest few rounds of testing, we used the Total Phase Advanced Cable Tester (a fancy, $1,500 piece of equipment) to scrutinize the wiring and signal integrity, DC resistance, and compliance with USB-C specifications of every cable we tested. We also used it to double-check our other data-transfer speed and power-draw measurements.
To test the data-transfer capabilities of the USB-C–to–USB-C cables for phones, tablets, and laptops up to 60 W, we plugged one end of each cable into a portable SSD, and the other end into a 2016 13-inch MacBook Pro with four Thunderbolt 3 ports. We then ran a free system-performance app called AJA System Test Lite on the laptop to measure read and write speeds in MB/s (megabytes per second). To test power draw, we used the 13-inch laptop, a Satechi ammeter, and a first-generation Google Pixel phone, and we noted the maximum power-draw readings on the ammeter as well as on the laptop’s System Report.
To test the data-transfer capabilities of USB-C–to–USB-A cables, we plugged the USB-C end into the 13-inch laptop and the USB-A end into an Aukey USB-C–to–USB-A adapter (discontinued). We then plugged the adapter into the portable SSD, and ran AJA System Test Lite. To test power draw, we used the ammeter, the Pixel, and a USB wall charger, and noted the maximum power-draw readings on the ammeter.
To test the data-transfer capabilities of Thunderbolt 3 cables, we plugged one end of each cable into a LaCie Bolt3 (a desktop SSD with Thunderbolt 3 ports) and the other end into the 13-inch MacBook, and we ran AJA System Test Lite. To test power draw, we used the 13-inch laptop, the ammeter, and Apple’s 61W USB-C Power Adapter and noted the maximum power-draw readings on the ammeter as well as on the laptop’s System Report. To test USB-C–to–USB-C cables for the MacBook Pro and other high-powered laptops, we used the same methods but with the Samsung T3 instead of the LaCie Bolt3.
To test the data-transfer capabilities of USB-C–to–USB-A cables, we plugged the USB-C end into the 13-inch laptop and the USB-A end into an Aukey USB-C–to–USB-A adapter (discontinued). We then plugged the adapter into the Samsung T3 and ran AJA System Test Lite. To test power draw, we used the ammeter, the Pixel, and an Anker PowerPort II wall charger and noted the maximum power-draw readings on the ammeter.
To test USB-C–to–USB-A adapters, we plugged the USB-C end into the 13-inch laptop and the USB-A end into a SanDisk Extreme CZ80 16GB USB 3.0 Flash Drive and ran AJA System Test Lite. To test USB-C–to–Micro-USB adapters, we plugged the Micro-USB end into a USB-A–to–Micro-USB cable and the wall charger. We then plugged the USB-C end into the ammeter and the Pixel and noted the maximum power-draw readings on the ammeter.
Based on our testing of Lightning and Micro-USB cables in past years—we sent more than 70 cables to a former NASA engineer, who tore them apart to examine their internal components— we’ve learned that there’s little difference in their charging or data-transfer capabilities. So, to test USB-C–to–Micro-USB cables, USB-C–to–Lightning cables, and three-in-one cables, we mainly focused on the build quality of the sheath and housings, and we made sure the metal connectors fit snugly into corresponding ports.
On every test we ran, we took each measurement three times per cable (unplugging the cable between measurements) and calculated the average. After collecting data on all the contenders, we considered other factors—USB-IF and MFi certifications, length, price, availability, brand reputation, warranty and customer support, ease of use, packability, and aesthetics—to make our final decisions.
We plan to test USB-C cables supporting up to 240 W power transfer, and cables with Thunderbolt 4 capabilities, when compatible devices become more widespread.
To replace several older picks that have been discontinued, we also plan to test active Thunderbolt 3 cables, USB-C–to–Micro-USB cables, and 10-foot cables for charging USB-C phones, tablets, and laptops as soon as we can.
We’ve been asked about a recommendation for a USB-C extender cable (such as this model), but we don’t have one because they aren’t permitted under USB-C specifications. For a cable like this to work properly, it (and your other cables or connectors) would need to have heavy-gauge power wires, which would make the cable thick, inflexible, and expensive.
