But the tiny size, combined with the high-contrast picture, makes this an ideal companion for business presentations on the go. The lack of wireless connectivity is disappointing, and the fact that Optima sells a dongle to correct that oversight for an additional cost is borderline insulting. The projector is also on the expensive side. You will want to ensure your presentation room is as dark as possible. It's ideal for business because it's bright enough for a conference room and small enough for a briefcase or backpack. The size becomes even more impressive when considering this powerful machine's 700 ANSI lumens and 20,000:1 contrast ratio. In this case, you can get a 100-inch projection just six feet away. It's also a short-throw projector, so you can have the projector close to the screen and still have a full-sized picture. Photos of the projector don't show how small this projector is. There are mini projectors, and then there's the Optima ML 750ST. Resolution: 1080p | Brightness: 50 ANSI lumens | Contrast Ratio: 2000:1 | Projection Size: 30 to 100 inches Overall, this device is small enough to fit into a jacket pocket or a small bag, making it ideal for campers, hikers, or anyone who wants to tote their projector. The included tripod lets you point the projector anywhere you need it. You can connect to your projector using the HDMI input or plug in a USB drive to display photos and movies. Still, we like to see that kind of versatility in devices. You can also charge your phone off the battery, leaving even less power for the projector. The projector comes with a 3,400 mAh battery built-in, which will barely get you through a 2-hour movie. However, it also has a dim picture, so you'll want to set this projector up in as dark a room as possible. This device is about the size of three CD cases stacked on top of each other and has decent sound. Keeping in line with portability comes the Apeman M4 DLP projector. Resolution: 720p | Brightness: 200 ANSI lumens | Contrast Ratio: Not listed | Projection Size: 40 to 100 inches It's not cheap, but it's got everything you need. Overall, we like the Nebula Capsule II and it's the perfect solution for a pop-up cinema night or even as a bedroom TV for occasional use. You can also control it using Google Assistant, a smartphone app, or the supplied remote. The projector runs on Google's Android software, so with the easy-to-use interface, you can easily download apps like Netflix or Hulu, plus you get the bonus of built-in Google Assistant. It's got everything you need, including a speaker built into the base and a built-in app store-connect it to a Wi-Fi network, and you're good to go. When it comes to that, the size of a soda can is about as small as you can get (especially as most bags and backpacks have pockets designed for carrying drink-sized items). When considering mini projectors, portability is one of the prime considerations.
