– 200 ANSI Lumens | Dust-Sealed Optical Engine | 1280×720 Resolution. The J3 delivers a watchable image without needing complete blackout conditions. The dust-proof engine stops airborne particles from reaching the LCD panel, eliminating dark spots over time. Combined with native 720P resolution, the J3 produces clean, detailed visuals. The 1.3:1 throw ratio hits a 100-inch screen at roughly 2.8 meters.
– Electronic Trapezoid Correction | 360° Side Projection | Powered Focus. Traditional projectors demand dead-center placement. The J3 does not. Electronic correction works from any angle. Side projection keeps the image rectangular even when pointing diagonally. A motorized focus system handles adjustments with a button press. Auto-focus version optional. Set it down, turn it on, get a sharp, square image in seconds.

– 162×157×123mm | WiFi 6 Dual-Band | 4Ω 3W Audio | USB+HDMI. At just over one liter, the J3 disappears into any bag. WiFi 6 handles 2.4GHz and 5GHz for smooth streaming. The 4Ω 3W speaker uses an independently designed acoustic cavity for clearer dialogue and fuller sound. USB reads flash drives. HDMI connects consoles, laptops, or streaming sticks. Works wirelessly, with a cable, or from onboard apps.
