The Ulanzi HT005 is a dedicated DC power adapter designed to provide a steady energy source for Ulanzi 40W PRO and 40W RGB lights. It converts a standard 100-240 VAC input into a 19V output with a 3.42A current, delivering a total power of 64.98W to ensure your lighting remains consistent during long shoots. This black adapter comes with a US-style plug and a total cable reach of 2.7 meters, which is split between a 1.5-meter power cord and a 1.2-meter adapter cord. This length gives you more flexibility in where you place your power outlet relative to your light setup. The package includes both the DC adapter and the necessary AC power cord for immediate use.
