To recharge, either use the built-in USB-C port for up to 1.5A charging, or simply pop out the cells, and replace them with a freshly charged set.
PowerPlay’s Power section is a pair of two 18500, Li-ion cells, that can power a Dominator HDO + rapidFIRE + DVR for up to 3 hours *.
The internal DVR on FatShark Dominator Goggles is ‘ok’, but it doesn’t come close to the quality that PAL/NTSC can offer. Instead of the MJPEG compression used in the Dominator, the PowerPlay uses x264 (AVC) compression, with a much higher bit-rate. The 30fps frame rate of the Dominator is also doubled to 60fps, which is essential for capturing fluid race footage. Product Description: ImmersionRC PowerPlay FPV DVR H264 60FPS
