Verdict
ASUS P3B is a short-throw LED projector for coffee-table use, but weak contrast, high-pitched fan noise and about one hour of battery hold it back.

Verdict
ASUS P3B is a compact battery projector for presentations and small rooms, but its 1280 x 800 resolution and modest colour limit movie watching.

  • Built-in 12,000mAh battery provides up to 3 hours of cable-free use and functions as a power bank
  • Versatile connectivity options including HDMI, MHL, VGA, microSD, and USB ports
  • Bright 800-lumen output for its size, providing sharp WXGA (1280x800) visuals in low light
  • Long-lasting LED light source with a 30,000-hour lifespan

What customers don't like about ASUS P3B

  • Remote control is often cited as small, cheap-feeling, and sometimes unresponsive
  • In-built speakers are relatively quiet and may not fill larger rooms
  • Image quality and brightness can drop noticeably when running on battery power versus AC power
  • Limited local media playback functionality, such as difficulty with specific video formats (Cinemascope) or external hard drives
  • Wireless connectivity and networking features can be finicky or require additional dongles to work reliably
  • User interface and menu systems are not considered very user-friendly

Verdict

The ASUS P3B is an ultra-portable LED projector featuring a native WXGA (1280 x 800) resolution, an 800-lumen light source, and a 100,000:1 contrast ratio within a compact 750g frame roughly the size of a CD case. Main characteristics include a 30,000-hour lamp life, a 12,000mAh built-in battery providing up to 3 hours of wireless projection, and a short-throw lens capable of projecting a 200-inch image from just 3.4 meters away. Key pros are its extreme mobility, ability to double as a power bank for mobile devices, and versatile connectivity including HDMI/MHL, VGA, and a microSD card slot for PC-free presentations. Notable cons include a significant drop in brightness to 300 lumens when running on battery power, reported issues with uneven focus across the entire image, and a cooling fan that can be noisy during plugged-in operation.
