The mini projector has invaded living rooms and backpacks: outdoor movie nights, big-screen gaming, nomadic presentations... But with dozens of models out there, how do you choose without getting it wrong? Here are the criteria that really matter.
How does a mini projector work?
A mini projector displays the image from your smartphone, PC or console onto a wall or screen using a light source (LED or laser) and a display chip. The most common technologies are DLP (good contrast, sharp image) and LCD (rich colors). Compactness no longer sacrifices quality: the best models fit in one hand for a picture up to 120 inches.
The 5 essential criteria
1. Brightness (ANSI lumens)
This is the #1 criterion: below 200 lumens, the image washes out as soon as there is ambient light. For evening/camping use, aim for 300 lumens or more; for a bright room, 500 lumens and beyond.
2. Resolution
720p is the acceptable minimum, Full HD (1080p) is the comfortable standard for movies and gaming. Beware of "4K supported" which often just means upscaling.
3. Connectivity
HDMI (console and PC), USB-C (power and video), Wi-Fi and Bluetooth for audio. AirPlay/Cast compatibility is a real plus for casting from a phone without cables.
4. Battery and size
Expect 1.5 to 3 hours on the internal battery for portable models. Under 500 g = truly nomadic; otherwise the projector stays in the living room.
5. Auto adjustment
Keystone correction and autofocus save a huge amount of time: without them, every setup becomes a chore.
Which use, which model?
- Home movie nights: Full HD, decent built-in audio, 300+ lumens
- Camping / outdoors: long battery, lightweight, durable
- Gaming: low latency, HDMI, 1080p resolution
- On-the-go work: USB-C, small size, 100-inch projection for meetings
Mistakes to avoid
Don't trust the "4000 lumens" advertised on low-cost specs: manufacturers often inflate the numbers. Look at ANSI lumens, the warranty and verified reviews. Also avoid models without keystone correction if you project at an angle, and check that the native (not "supported") resolution is Full HD.
FAQ
What distance for a big picture?
As a rule of thumb, 2 meters of distance gives an image of about 80 inches. Optical zoom is rare on mini projectors, so plan your distance accordingly.
Can a mini projector replace a TV?
For daily use, a TV remains brighter and simpler. The mini projector excels for nomadic use, movie nights or the bedroom.
Is the sound good enough?
Built-in speakers are decent but lack bass. Pairing a small Bluetooth speaker transforms the experience.
