With up to 166W of power for lights or other electronic devices, the multipurpose H99 PRO Battery Grip from Sirui features a built-in 97Wh, 26100mAh battery that can be recharged in less than two hours using either the USB-C or D-Tap inputs and included cables. Two outputs—one USB-C and one D-Tap—provide up to 20 and 22.2V of power to connected lights or accessories. Attach the light to the handle via the top 3/8"-16 screw or to a stand with the bottom 3/8"-16 or 1/4"-20 threads.
The handle's all-metal construction features four LED charging indicators and a rubber clamshell cover to prevent the top screw from scratching other accessories. Capable of powering any light with a USB-C or D-Tap input, the H99 PRO is well-suited for use with the pocket-sized Sirui C150X LED light, available separately. The battery grip is rated for 46 minutes of continuous use with the 150W fixture and up to 60 minutes with 100W lights.
