Despite looking like and being as small as a Bluetooth speaker à la JBL Charge, the Nebula Capsule 3 Laser is a fully fledged projector that costs roughly €850 (US$930). It is equipped with a Bluetooth speaker and, much like a Bluetooth speaker, is powered by a battery so that you can use it on the go. We have tested out the device to see how well it works and how long it lasts on a single charge.https://www.notebookcheck.net/Anker-Nebula-Capsule-3-Laser-hands-on-review-pocketable-projector.770745.0.html
This is really cool and I look forward to a review of the larger version. I can imagine a future where people carry these around with them, or they eventually can get down to the size that a smartphone could reproduce images via laser projection. Someday...
