Nebula Anker Nebula Capsule II Mobile Projector I have confirmed its operation. I was able to watch YouTube for 2 hours and 20 minutes until the power ran out. I checked the operation with the volume turned down, so the viewing time will be shorter if you turn up the volume. Also, please note that this may vary depending on the playback environment. Power adapter and charging cable are not included. There are scratches and dirt. If you are not concerned about the above, please consider purchasing. Type...Portable
