How we picked and examined
Every sort of adapter or connector we evaluated required totally different sorts of testing, however we have been ready to make use of some frequent exams throughout the board. Our principal testing machine was a MacBook Pro (13-inch, Late 2016, Two Thunderbolt 3 Ports), with ancillary testing performed utilizing a 2016 Dell XPS 13, our decide for the best Windows ultrabook. We examined the data-transfer pace of the USB ports on hubs and adapters utilizing our favorite flash drive from SanDisk with the AJA System Test app, repeating the take a look at 3 times per machine. To check USB-C–to–USB-A cables, we linked Samsung’s Portable SSD T3 (one of many quickest drives with a USB-C connection) to the Dell XPS 13 and ran CrystalDiskMark.
We examined video adapters utilizing a Dell P2715Q (our decide for the best 4K display), Intel’s Cranium Canyon NUC pc, an older VGA monitor, and a 1080p TV. We measured the refresh fee utilizing the Blur Busters Motion Tests.
For connecting older USB gear: USB-C–to–USB-A adapter
If there is a single accent most individuals with a USB-C–solely pc will want, it is a USB-C–to–USB-A adapter. Obtainable as both a small nub or a brief cable, this sort of adapter helps you to join legacy USB equipment, together with flash drives and cables, which have a conventional USB-A plug. We examined 9 adapters and located that all of them work equally nicely. Our favourite nub-style adapter is Aukey’s CB-A1-2, obtainable in a two-pack for lower than $10. The plastic-bodied dongle is a bit over an inch from finish to finish, about half an inch huge, and barely thicker than the USB plug that you’re going to hook up with it.
In the event you choose a brief cable over a nub adapter, go together with Anker’s USB-C to USB 3.1 Adapter. The black cable feels sturdy and has stable housings on the ends. The benefit of a cable over a nub is that it strikes the connector away from the pc a bit—about 5 inches on this case—which may make connecting bulkier units with out blocking different ports simpler.
For video, USB-A, and charging from a single USB-C port
Our favourite adapters for including USB-A ports, connecting to HDMI shows, and powering your pc on the identical time are Sanho’s HyperDrive USB Type-C Hub and Satechi’s Slim Aluminum Type-C Multi-Port Adapter. They’re an identical in each means, together with design, efficiency, and MSRP. Every consists of a solid-feeling aluminum block that connects to your pc by way of a completely connected, 6-inch USB-C cable. On one edge are two USB three.zero ports and a USB-C port—the latter just for passthrough charging—and a single HDMI port is discovered on the tip reverse the cable. Sadly, every USB port offers a most of solely zero.45 amps to linked units, so neither adapter is well-suited for charging units or powering bus-powered laborious drives.
For video solely: USB-C–to–DisplayPort cable
In the event you’re connecting to a DisplayPort-based monitor, you may want a devoted cable—not one of the adapters we examined embody a DisplayPort port. (In the event you’ve acquired a MacBook with solely a single USB-C port, you may as a substitute want to make use of an HDMI-to-DisplayPort cable with one of many adapters with an HDMI port.) Each USB-C–to–DisplayPort cable we examined labored completely, providing a pixel-perfect picture and full 60 Hz efficiency, even at 4K. That mentioned, we suggest Cable Matters’s USB-C to DisplayPort 4K 60 Hz Cable if it is obtainable. It is the one one of many three cables we examined that has a clip on the DisplayPort plug housing to carry the plug in place—it’s important to squeeze the clip to launch the cable from the port.
For a number of older USB units: USB-A hub
For many who do not want video output however nonetheless need passthrough energy and a number of ports for older peripherals, we like HooToo’s HT-UC004 Shuttle USB 3.1 Type-C Hub. It is wider and thicker than the HDMI-equipped adapters from Satechi and Sanho, however quite a bit inexpensive. Along with a USB-C port that helps Energy Supply for passthrough charging, it consists of three USB three.zero ports, in addition to an SD card slot—the latter one thing we did not think about crucial for this class, however a pleasant further. Nevertheless, as with different adapters, the HooToo’s USB ports present solely a disappointing zero.45 amps for charging—you will not have the ability to cost telephones or tablets at something close to full pace, and a few bus-powered units, similar to laborious drives, could not work correctly.
For energy and information between USB-C units: USB-C–to–USB-C cable
Probability are you may finally want a USB-C–to–USB-C cable for charging and connecting USB-C units. You will discover a ton of cheap choices, and although we would usually lean towards saving a couple of dollars on cables, that is not well worth the threat with USB-C: Some cables that do not adhere to the USB-C specification can really fry your computer. You must spend a bit bit extra to get one thing that is verified to work safely together with your machine.
Based mostly on the testing he and Google engineer Benson Leung have performed, Nathan K., a member of Google’s Top Contributors Program and an unbiased USB-C accent tester, recommends J5Create’s JUCX01 in his accessory guide, the place it is ranked “undoubtedly get.” We examined the cable ourselves, and although our exams weren’t as exhaustive, the cable labored nicely for us. It helps USB three.1 Gen 2 speeds of as much as 10 Gbps, in addition to 5-amp and 100-watt charging, and it is USB-IF licensed. Put merely, it would cost your pc as quick as potential (so long as you are utilizing the right charger) and can transfer information as quick as USB can. Each JUCX01 additionally has a novel serial quantity, so if the corporate ever has a recall or assist subject, you may know in case your cable is affected.
In the event you’re not involved about shifting information on the quickest speeds, Apple’s USB-C Charge Cable is a good cost cable that is a bit inexpensive than our prime decide. (Simply be sure you get model MLL82AM/A in a rectangular, not square, box.) It provides 5-amp, 100-watt charging (probably the most energy USB-C is designed to offer), however helps solely USB 2.zero information speeds, so it will likely be significantly slower than the J5Create should you’re transferring information.
For charging USB-C units: USB-C charger
In 2015, PCWorld ran a test evaluating USB-C chargers throughout totally different laptops and located that no single charger might even cost each pc, not to mention cost all of them quickly. Because of this, we suggest utilizing whichever charger got here together with your pc, or an adapter particularly really helpful by your pc’s vendor. If it is too troublesome or costly to interchange your pc’s inventory charger, we like Apple’s 61W USB-C Power Adapter as a result of it is broadly obtainable and works with many non-Apple units. You may examine this adapter and our different suggestions in our guide to USB-C chargers.
For connecting to VGA projectors and shows: USB-C–to–VGA adapter
If it’s essential to hook up with a projector or an older monitor with a VGA connection, the best choice is Kanex’s USB-C to VGA Adapter. All of the adapters we examined labored equally nicely, pushing out 1920×1080 decision at 60 Hz. The Kanex mannequin is without doubt one of the least costly we discovered, it comes from a really respected model, and it has the longest cable of any VGA adapter we examined—an extended adapter cable provides you extra flexibility for connecting video cables, and reduces the stress these heavy cables put in your pc’s ports.
For connecting to HDMI screens and TVs: USB-C–to–HDMI adapter
The easiest way to attach a USB-C pc to a high-definition TV or monitor, even at 4K decision, is to make use of Anker’s USB-C to HDMI Adapter. All 5 of the adapters we discovered that promise a 60 Hz refresh fee labored as marketed. The Anker is our decide as a result of it is pretty cheap, it has a pleasant metallic physique, and it really works with the 2016 and 2017 MacBook Professional. Another fashions both explicitly warn that they do not work with the most recent Macs or have buyer evaluations claiming as a lot.
For connecting to legacy chargers and older computer systems and peripherals: USB-C–to–USB-A cable
If you would like to attach a USB-C machine to an older pc or charger that has solely USB-A ports, you may want a USB-C–to–USB-A cable. In the event you’re involved extra about charging speeds than data-transfer speeds, we suggest Anker’s PowerLine USB-C to USB 3.0 Cable. Very like Anker’s Micro-USB and Lightning variations of the cable, this one contains a easy design and good development at an reasonably priced value. We noticed energy draw approaching three amps after we plugged it right into a high-amperage USB-A port, and its information speeds have been on a par with each different USB three.zero cable we examined.
At this level, only a few units assist the 10 Gbps information fee that USB three.1 Gen 2 cables can supply, so we do not assume most individuals have to spend the additional cash on a Gen 2 cable. In the event you can reap the benefits of these speeds or wish to future-proof, we suggest Google’s USB-C to USB-A Cable. It matches the charging charges we would count on, and although we measured learn speeds of three.49 Gbps and write speeds of three.32 Gbps on the USB three.1 Gen 1 Samsung T3, it will theoretically assist sooner speeds with sooner units. The construct high quality can also be very nice: The cable is thinner than that of many different fashions, and the well-designed strain-relief collars ought to assist forestall breakage over time. It even has a built-in plastic clip for preserving the cable coiled.
For connecting to DVI shows and projectors: DVI adapter
We discovered solely a handful of DVI adapters that declare to deal with 1920×1080 decision at 60 Hz, and one of the best amongst them is StarTech’s USB-C to DVI Cable. In contrast to the opposite adapters we examined, this one would not require a separate DVI cable: It has a USB-C plug on one finish and a male DVI connector on the opposite. In our exams, the decision and refresh fee have been precisely as promised.
In the event you want an adapter with a feminine DVI connection, Cable Matters’s USB 3.1 Type C to DVI Adapter additionally did nicely in our exams, however evaluations on Amazon counsel points with some MacBook Professional fashions.
