Laser and battery, with the operating system as the product
Projectors designed to work alone: a light source, a speaker, a battery on some models, and a television operating system on board. Several models quote ISO lumens, a measured unit, rather than the unqualified figure this end of the market usually prints.
The built-in system is the part that ages, and it is a licensing question rather than a hardware one. Which streaming services run at full resolution on a given model is worth checking on the maker’s own page before buying — that answer changes with firmware.
Laser light source · battery powered · portable · home cinema and outdoor use stated
A laser projector small enough to carry and run on its own battery — the light source decides how it looks, the battery decides where it goes, and both are stated.
Best for: A garden in summer, a second room, or anywhere a mains socket and a dark room cannot both be arranged.

Foldable · 70 inch · outdoor and camping · HD
A 70-inch foldable screen from a projector maker — sized to match what a portable machine can actually light.
Best for: Travelling with a portable projector — camping, a garden, a holiday — where the projector and the screen go in the same bag.
≈ 69 €
Native 1080p · battery powered · Google TV · portable, outdoor use stated
A battery projector on Google TV from a maker that states ISO lumens on its larger machines — here the brightness figure is absent, and the page says so.
Best for: A self-contained machine for a dark room or a garden after dusk, from a range whose larger models are specified properly.
