The brightness claim to read twice
This is the shelf where the brightness claim is at its worst. A battery projector that genuinely produces 200 to 400 ANSI lumens is routinely advertised at "9 000 lumens", and both numbers can appear on the same listing. Read the unit, and when there is none, treat the figure as marketing rather than measurement. Past that, the family divides on three things: battery runtime at a stated brightness, which is usually one film and rarely two; what runs on it, since a built-in operating system that lacks a licence for one service is a common and undocumented limitation; and sound, because a small chassis holds a small speaker, and the audio output you can reach matters more here than in any other family. We compare stated brightness with its unit, native resolution, battery runtime, built-in apps and licensing, and audio outputs.
Portable · Wi-Fi 6 · Bluetooth · 360° rotating foot · power bank input · phone pairing · 4K signal accepted
The cheapest projector in this catalogue: a small machine with a rotating foot and a power bank input, and no brightness figure to compare it by.
Best for: Finding out whether a projector suits the household at all, before spending anything that matters.
≈ 93 €
Battery · Android 11 · Wi-Fi 6 · Bluetooth 5.2 · 220° rotation · auto keystone · 4K signal accepted
A battery projector built around convenience — rotation, automatic keystone, Wi-Fi 6 — whose brightness the maker does not state in a measured unit.
Best for: A machine that gets carried between rooms and set down anywhere, where setup speed matters more than a comparable specification.
≈ 120 €
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.
≈ 209 €
Full HD · 350 ANSI lumens · battery · Google TV · autofocus · HDR10 · Dolby Digital+ · hard case included
A battery projector that states its brightness in ANSI lumens — 350 — which is honest, comparable, and exactly what a portable machine actually produces.
Best for: A bedroom ceiling, a garden after dusk, or a machine that travels — anywhere the alternative is no projector rather than a better one.
