Compact YOWHICK Projector and Speaker - Brand: YOWHICK - Remote Control: Included - No instruction manual or box - Volume Adjustment: Dial type From the time of purchase, a small shadow-like mark may appear on the screen. It's not noticeable when watching videos. Output is HDMI. The projector has a built-in speaker, but the sound is quiet, so I connected a separate speaker. The included speaker draws power from the projector when connected. The projector can be used with a tripod, like those found at 100-yen shops.
