Nebula Capsule Smart Mini Projector, by Anker, Portable 100 ANSI lm High-Contrast Pocket Cinema with Wi-Fi, DLP, 360° Speaker, 100″ picture, Android 7.1, 4-Hour Video Playtime, and App

This is a revolutionary product — a very usable portable projector. It is decently bright; can work for hours on battery; can sit nicely on most surfaces and also comes with a standard tripod screw hole. It comes with Android 7.1, so it works as a portable smart TV on its own. It can also mirror screens of cell phones (I tested both IOS and android) and computers through wifi and bluetooth. Therefore, it has a very convenient and truly wireless setup. There is simply no other non-Anker/Nebula portable projector available today (Jan 2018) in its league.

The only projector worthy of comparison is the Nebula Mars. For not too much more money (especially when Mars has a discount), you get 500 ANSI Lumens vs 100, 1280×800 resolution vs 854×480, 19500mAh battery vs 5200mAh, 10W JBL speakers vs 5W unknown speakers. So Mars seems like a better deal. However, I simply cannot get over the portability of Capsule. In my mind, this single factor outweighs all the rest of them. Moreover, Capsule runs Android 7.1 now and probably will get an Android 8 upgrade, while Mars still has Android 4.4. That is another plus for Capsule. Actually, the two seem to have the same processor, RAM and ROM, so maybe Mars may also have the updated software one day?

The Amazon page is missing most of the specs mentioned above. Instead of brightness, battery capacity and resolution, it mentions picture sizes and playtime. But the specs should nevertheless be there.

I have been using this device for two days, for projecting my screen when working, and for movies. When projecting 100″ images, it is perfectly bright in a dark room at night, but is very dim during daytime even with the curtains closed. But I can always move it closer to the wall and make the projection smaller. At 30″, the pictures are visible even in a bright room. So in terms of brightness, I would say it is very usable. There are two modes: standard and “battery”. I assume the latter will make it dimmer. The battery life is amazing. The Amazon description says 4 hours, while the Indiegogo description says 2.5 hours. With the device set to standard mode, I could use it nonstop (steaming videos online) for 4 hours and still have about 30% charge left. It has automatic vertical keystone correction. There is no horizontal ones, but that is normal. It is suggested to work below a relative humidity of 85%, and does not seem to have any IP ratings, so using it in the bathroom may not be a good idea. To stream media from a USB flash drive, you have to use the provided micro USB male to USB A female cable that is about 2 inches long, like a tail to the device. While the setup does not look nice and the conversion cable is one more thing to carry, it is a pretty logical choice.

The device is very well packaged — better than Apple products, I would say. It also comes with high-quality accessories, including a travel porch with the same material as those for Anker batteries, an Anker micro USB cable and a nice compact charger with Quick Charge 3.0.
