DJI's new USB-C cable shows real-time wattage on a built-in display

DJI has announced a 240W USB-C cable with a small real-time display built into one of its connectors, showing live wattage, voltage, and current as you charge. The cable supports up to 7A and is braided for durability. It arrives as part of DJI's push into the wider power accessories market — well beyond drones — bundled with the company's new 140W GaN charger at around $30, per Gizmochina.

The display

The headline feature is an E-Marker chip paired with a small screen on the connector. It shows power in watts, voltage in volts, and current in amps in real time — so if your laptop is charging slower than expected, you can immediately see whether the cable, the charger, or the power bank is the bottleneck. It's a genuinely practical tool for anyone who's ever doubted whether a charger is actually hitting its advertised spec.

At 240W maximum throughput, the cable can handle gaming laptops and DJI's own portable power stations, not just phones. The 7A current rating puts it above most standard USB-C cables on the market.

The catch

Data transfer is capped at USB 2.0 speeds — a limitation that looks odd in 2026 but is actually standard practice for high-power cables. Manufacturers drop the extra data lines to keep cables flexible and costs low. This cable is for charging, not transferring 4K drone footage. Competing 240W display cables from UGREEN offer similar specs at $40–50, with some variants pushing USB 3.2 data speeds, so the trade-off is worth noting before buying.

Availability

The cable is currently bundled with the DJI Power 140W GaN charger; a standalone retail price hasn't been confirmed. As of June 2026, there's no dedicated listing on the DJI US or UK store for the cable on its own — it may appear on Amazon.com and Amazon.co.uk through third-party sellers. The $30 bundle price undercuts UGREEN's standalone cable, but locks you into DJI's power ecosystem. If you already own DJI charging gear, that's a reasonable trade. If you don't, a purpose-built display cable from a specialist brand may offer more flexibility.
