Updated by Tomas Lindgren. Three must-haves, six small fixes and three bigger add-ons.
Start with three: a 100-inch screen, a streaming stick for projectors without licensed apps, and a 65 W USB-C power bank for USB-C models. After that, a stand, an iPhone HDMI adapter and blackout curtains solve the most common complaints people have in their first week.
On projectors with licensed Google TV, Roku or Samsung Tizen, yes. On plain Android boxes and mirroring-only models, often not: copy protection blocks mirrored Netflix, and some projectors can't install the official app at all.

Battery models usually last about 2.5 hours, which covers one movie. USB-C models have no battery but run from a power bank, as long as it delivers 65 W or more over USB-C PD. Phone-sized banks won't start them.
65 Wminimum USB-C PD for the D1R Air (Notebookcheck) and BOOM Air (listing)
For a bedroom, usually yes: most minis carry 5 to 12 W. For a backyard, no. The Mars 3's 40 W speakers are the exception in our data. Otherwise add a Bluetooth speaker placed near the audience.

The screen, the stick and the power bank fix the three most common complaints.
TOWOND 100-inch portable screen
A real screen is the cheapest brightness upgrade there is: a white matte surface reflects more evenly than a painted wall, and the stand lets you set up anywhere.
What to look for: Look for a wrinkle-resistant fabric and a 16:9 frame that matches your projector.

PUTORSEN universal stand with 1/4-inch screw
Getting the lens level with the middle of the screen avoids heavy keystone correction, which costs sharpness.

For projectors without AirPlay, this is the wired route. Some streaming apps block video over adapters; a stick avoids that.
What to look for: MFi certification for Lightning, and a charging port so your phone doesn't die mid-movie.

Check today's price on AmazonPeople searching 'screen projector' usually want a projector and a screen together. A white wall works; a matte white screen looks more even and a bit brighter. Gray walls cost brightness.
Gain is how much light a screen reflects compared with a standard white board. 1.0 is neutral; higher gain looks brighter head-on but dimmer from the sides.
No. It needs USB-C PD output of 65 W or more, and the cable must be rated for 5 A (E-marker). Check both before you buy.
Most minis have a standard 1/4-inch tripod socket underneath. Check the bottom of yours, and pick a stand that holds its weight with the head tilted.
Blow off dust first, then wipe gently with a microfiber cloth and alcohol-free lens fluid. Never spray the lens directly.
Yes. Cutting ambient light helps a 300-lumen projector more than doubling its brightness would in a lit room.
