Our take
The ASUS P2B is a genuinely portable WXGA projector with an internal battery pack, RGB LED illumination, and a documented 1.1:1 throw ratio. ASUS specifies 1280 × 800 DLP resolution and a 20–120-inch image range, which help define a compact setup. Its 350-lumen figure is not labeled ANSI, and the manual does not give battery runtime. Consider it when battery-backed placement and native WXGA matter more than a standardized brightness comparison or a long viewing session. Confirm charging, model variant, source connections, and operation on the individual unit.
Portable presentation or casual viewing where a battery and WXGA image are useful in a measured short conventional throw.
It is not for buyers requiring a verified ANSI threshold, a guaranteed runtime, bright-room projection, or an integrated subscription-app platform.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- ASUS identifies a native WXGA 1280 × 800 DLP image and a built-in battery pack.
- A 1.1:1 throw ratio and stated image-size range assist short-room layout planning.
- USB and microSD local media provide source options without always requiring a separate video player.
What to weigh up
- The 350-lumen specification is not an ANSI rating and should not be converted.
- No battery runtime is established in the reviewed ASUS manual.
- RGB LED illumination and battery operation do not establish a particular brightness or long-term unit condition.

What the features mean for you
Portability is backed by a documented battery pack
The ASUS P2B manual identifies a built-in battery pack, giving the model a real cordless-use basis rather than relying on a vague portable label. ASUS does not specify how long it runs in the pages reviewed, so there is no reliable runtime promise to use in planning. Battery age, brightness setting, source activity, and the condition of an older unit all matter. If a presentation, screening, or trip depends on unplugged operation, test that exact projector after charging and bring its adapter where possible. The battery makes placement more flexible, but it does not automatically make the projector suitable for a large audience or bright surroundings. Treat portability and usable image size as related but separate filters.
WXGA gives a clear native-detail baseline
ASUS specifies the P2B as 1280 × 800 WXGA using DLP imaging. That widescreen format has more native pixels than SVGA or WVGA models and is useful for slides and video formatted for a 16:10 canvas. It remains below native Full HD, so it is not the right choice if a 1920 × 1080 panel is essential. A larger incoming signal does not add pixels to the image engine. The model's stated range up to 120 inches is not a guarantee that such a large picture will be bright enough under every condition. Balance resolution with light output, room darkness, and the actual screen size you plan to use.
Keep the non-ANSI rating in its original units
The P2B manual lists 350 lumens but does not label that number ANSI. It belongs in the summary with that qualification and stays out of the structured ANSI field. Comparing it with a projector specified at 350 ANSI lumens would suggest an equivalence the source does not establish. Room light, picture size, LED mode, battery state, and screen surface can change what the audience sees. Buyers who need a dependable light-output threshold should select a model whose maker publishes an ANSI value. For personal battery-based projection, consider the P2B only after accepting that the saved evidence gives a different, non-ANSI measurement basis. This is a documentation limit, not a measured claim about image brightness.
The 1.1:1 ratio is short conventional placement
ASUS specifies a 1.1:1 throw ratio and a 20–120-inch image range. That can allow placement closer to the screen than a long-throw business projector, but it should not be confused with an ultra-short-throw design that sits close to a wall. Measure from the lens to the screen and match the actual image width to the ratio. Leave clearance for ventilation, power, and source cables. The reviewed manual does not establish optical lens shift, so place the projector squarely and at a suitable height instead of assuming a simple optical alignment adjustment. Test focus at the intended size and do not treat the maximum diagonal as a promise about legibility or brightness.
Local media does not equal streaming apps
The manual describes local media access through USB and microSD. That can be convenient for supported files stored on removable media, while the built-in battery removes a separate power cable for some setups. Those facts do not establish an Android TV or other built-in subscription platform. Use a compatible external streamer, laptop, or other source if a particular service matters, and verify the correct input path. The RGB LED light source is documented, so this is not a laser model; the number of lumens does not change that classification. Check the model label, battery charging, fan and focus behavior, ports, remote, and supplied adapter before purchase. This review evaluates the model documentation, not a personally tested unit.
What else to compare
Compare AAXA BP1 for a battery model with a stated ECO runtime and local media, or ViewSonic PJ458D for an explicit ANSI rating with AC power.

The decision
P2B fits a portable WXGA plan when its battery and 1.1:1 geometry help, and unspecified runtime and non-ANSI output are acceptable.
