In brief: USB-C to HDMI cables for connecting portable devices to monitors or TVs are nothing new, but Anker's latest product includes a unique array of features at an attractive price. It charges faster than similar adapters and significantly undercuts Apple's digital AV adapter with superior functionality. The new Anker Nano USB-C to HDMI cable adapter supports 4K 60Hz video output from various devices and includes a separate USB-C port that enables fast charging up to 140W. At just $29, it's one of the best deals for connecting phones, tablets, and laptops to external displays.Plugging portable devices into TVs or monitors for extended periods typically requires a separate charging cable. For laptops, this means sacrificing an extra USB port. Meanwhile, phones and tablets often drain their batteries since they lack additional ports.Anker's adapter solves this issue by adding a USB-C charging port, allowing mobile devices to stay powered while outputting video and freeing up an extra port on laptops.The charging port also supports Thunderbolt 4 and 5. While Apple's USB-C Digital AV Multiport Adapter also includes USB-C and HDMI ports, it costs more than twice as much and does not include an HDMI cable.Anker's adapter is compatible with a wide range of devices, including Apple and non-Apple phones, tablets, laptops, and handheld gaming PCs such as the Steam Deck, Asus ROG Ally, Samsung Galaxy Tab, Lenovo ThinkBook, HP Chromebook, and more. Users can mirror or extend their screens to external displays and close their laptop lids while in use. // Related StoriesHowever, size and placement constraints prevent the adapter from connecting to some displays, including several Samsung and Dell monitors, and the Nintendo Switch (the full list is on the Amazon listing). The most likely reason is the three-foot cable length, though Anker may eventually release longer versions. Additionally, some Samsung and Google phones may not charge at full speed when using PPS (Programmable Power Supply) connections.A similar adapter from Ugreen is available for $25, supporting the Nintendo Switch and featuring a 6.6-inch cable. However, it lacks Thunderbolt 5 support and maxes out at 100W charging. Anker's adapter hasn't yet gathered many Amazon reviews, but Ugreen's alternative has received positive feedback.Those who require a higher-bandwidth HDMI connection may want to consider Cable Matters' HDMI 2.1 adapter, which supports 4K at 240Hz or 8K at 60Hz. However, it only includes Thunderbolt 4 (100W charging) and requires a separate HDMI cable.
