Our take
The BenQ GS2 is a portable projector with a native 1280 × 720 DLP panel, 500 ANSI lumens and an integrated battery rated for three hours. A 1.3:1 fixed lens and 30–100 inch range suit a measured small setup, while USB-C DisplayPort and HDMI allow direct connection from compatible computers or players. BenQ also specifies IPX2 splash protection and 0.5 m drop protection. It is not an all-weather outdoor device, and Android 6.0 does not prove that a specific streaming service currently works.
Portable viewing in a dim room or on a trip where a built-in battery, compact size and direct USB-C or HDMI input matter more than high brightness.
It is not for a bright-room image, native Full HD, UST placement, or a buyer who requires a verified current app catalog. Check for the detachable WDR02U dongle if wireless projection or Bluetooth is part of the plan.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- BenQ rates the integrated battery for up to three hours and the projector at 500 ANSI lumens.
- USB-C DisplayPort, USB-A reader and HDMI provide several direct connection options.
- The model has documented IPX2 splash and 0.5 m drop protection for careful portable use.
What to weigh up
- The native image is 720p and the 500 ANSI output favors a dim setting and modest image size.
- Wireless projection and Bluetooth depend on a detachable BenQ WDR02U dongle.
- Android 6.0 is documented, but current streaming app support is not guaranteed.

Full review: how the features affect your choice
What the features mean for you
What can its 720p image show?
BenQ lists a native 1280 × 720 panel and a 16:9 aspect ratio. That matches standard HD video and keeps a portable screen in a familiar widescreen shape. It accepts higher inputs up to Full HD, but the panel still displays 720p detail. For a temporary wall image or modest screen in a dark room, this may be a reasonable portability trade-off. If the projector will sit close to viewers on a large screen or show small text, compare a native 1080p model and remember the source resolution does not change the GS2's native pixel count.
How much brightness should you plan around?
BenQ specifies 500 ANSI lumens for the GS2. That is a directly labeled ANSI figure and can be compared with other models using the same measurement term. The output is modest beside bright classroom or meeting-room projectors. A dim space and moderate image size are sensible conditions for a portable model at this rating. The manual includes an Eco or battery setting, which can affect output and runtime. Do not assume the rating means a daylight image will remain clear, or that an older unit still produces its original output.
Will the fixed lens fit your room?
The GS2 has a fixed 1.3:1 throw ratio and a stated 30–100 inch projection range. With no optical zoom, the lens-to-screen distance determines image size, so measure before setting down a table or placing a mount. Auto focus and vertical keystone can assist setup, but they do not make this an ultra-short-throw projector or replace the correct distance. A planned 100-inch image requires more throw than a bedside picture. Compare your available distance with the screen width, and leave ventilation space around the body.
What sources and wireless features are included?
BenQ lists one HDMI input, a USB-A reader and USB-C DisplayPort. The USB reader can play supported local files, while USB-C can carry a compatible display signal. The GS2 also includes Android 6.0, but that system version does not establish current support for a specific service. BenQ says wireless projection and Bluetooth depend on the detachable WDR02U dongle. Confirm that it is present and test the intended phone or computer. HDMI remains a straightforward fallback for movie playback.
How should you treat the battery and protective ratings?
BenQ rates the battery for up to three hours and lists a three-hour charging time from empty. A used battery may provide less, so verify it with sustained playback before planning a full screening. The GS2 is rated IPX2 and drop resistant from 0.5 m; these ratings do not make it waterproof or impact-proof for rough outdoor use. Its two 2 W speakers support personal viewing, while a group may want separate audio. Keep the lens, ports and cooling path protected during travel.
Compare for your needs
A native Full HD or higher portable projector is a better fit when detail matters more than battery convenience. The GS2 is distinct for its built-in battery, USB-C display input and documented physical protection, balanced against 720p and 500 ANSI lumens.

Before you buy
Is the GS2 native Full HD?
No. BenQ lists native 1280 × 720; accepting a Full HD input does not increase panel resolution.
How long is its battery rated to last?
BenQ specifies up to three hours, but a used battery may provide less and should be checked.
Does it have built-in streaming apps?
BenQ documents Android 6.0, but the checked sources do not establish current support for specific services.
Can it cast wirelessly without an accessory?
BenQ says wireless projection and Bluetooth use the detachable WDR02U dongle; confirm it is included.
