Ultra-portable projectors, like the EZCast Beam J4A projector, have seen many uses through the years. First, they helped meetings to occur anywhere without regard for existing AV. Then, during COVID, they were used for entertainment and displays during socially distanced gatherings. I have one to review – Read on to see what I think! What is it? The EZCast Beam J4A projector can best be described as a combination of an Android 10 device, a hybrid IR pushbutton remote/Bluetooth air mouse remote, and a DLP movie projector with auto vertical keystone adjustment and a built-in battery. The Android system is powered by an ARM Quad-core Cortex-A55 CPU and ARM Mali-G31 GPU and has 8 GB of storage. The device does not come installed with Google Services. The Android UI on the screen is easily accessed by swiping the included remote through the air once it is paired by Bluetooth. The Projector has 300 ASNI lumens brightness, 20,000+ hours LED lamp life, 5000:1 contrast ratio, and a progressive scan display resolution of 854 x 480. The battery in the display can power the system for 4 hours.
