8m (JCC154G).

Overview

The j5create JCC154G is a USB-C to HDMI cable that supports pass-through charging up to 7.5W via a separate USB-A power input. It delivers crisp 4K resolution at 60Hz with HDR support, making it an excellent choice for mirroring or extending your tablet, smartphone, or laptop display onto a larger screen. The 1.8-meter length offers flexibility, and the plug-and-play design requires no additional drivers. Built with an aluminum housing, it feels premium and durable.

Connectivity & Compatibility

This cable relies on USB-C DisplayPort Alt Mode, so your source device must support video output over USB-C. Compatible devices include iPad Pro (2018 and later), iPad Air (4th gen), many Android phones (Samsung Galaxy, Google Pixel, etc.), and USB-C laptops like MacBook and Windows ultrabooks. The HDMI side conforms to HDMI 2.0, supporting 4K@60Hz, HDR10, and HDCP 2.2. The dedicated USB-A power input (1.2m cable) must be connected to a USB charger (5V/1.5A or higher) for pass-through charging. No software installation is required — simply connect and use.

Product Info

The j5create JCC154G was released around June 2021 and is widely available on Japan for approximately ¥1,980. It occupies a unique niche: most USB-C to HDMI cables lack a dedicated charging pass-through, making this model stand out for users who need simultaneous power delivery. The aluminum casing adds build quality, and the cable is backed by a standard one-year manufacturer warranty. Accessories include the main cable and a quick-start guide. Market positioning is entry-to-mid tier, offering excellent value for its specialized feature set.

Best Use Cases

① Tablet users who stream or present for long periods iPad Pro/Air owners can output to a TV or monitor without draining their battery. The pass-through charging (7.5W) is sufficient to maintain battery level during video playback. However, for power-hungry tasks like gaming, you may need a higher-wattage charger or the tablet may still drain slowly. ② Android phone users who want a big-screen experience With a compatible Android phone (e.g., Galaxy S21+, Pixel 6), you can mirror the display to a larger monitor while keeping the phone charged. Ideal for watching movies, giving presentations, or using DeX mode on Samsung devices. Check your phone’s USB-C specification beforehand to ensure Alt Mode support. ③ Laptop users needing a simple multi-monitor setup Connect your USB-C laptop to an external display and charge simultaneously. The JCC154G works well with light workloads like web browsing or office tasks. For heavier loads, the limited 7.5W pass-through may not keep the battery from discharging — consider a full-featured Thunderbolt dock for that scenario. Who should look elsewhere? Users who only need a standard USB-C to HDMI cable without charging can save money with a simpler adapter. Those requiring higher refresh rates (120Hz+) or 8K output must look for HDMI 2.1 cables.
