Backyard movie night lives or dies on three specs: enough lumens for dusk, a battery that outlasts the credits, and a throw ratio that fits your yard. Of the 10 portable projectors we track, these three deliver.

Timing
Projectors can't fight daylight. What lumens buy is start time: with the brightest units in our set you can roll the film at dusk instead of full dark — with kids, that difference is the whole evening.
The runtime check
The longest battery in our set runs 5 hours — comfortably past most features. Streaming over Wi-Fi drains faster than local playback, so if your double feature is ambitious, bring the power cable or a station.
The data
Sorted by overall score, highest first. Missing specs show as — and are excluded from that model's score with the remaining weights rescaled. Full formula on the methodology page ↗
