Our take
The Nebula Solar Portable D2131 is a portable-style Full HD projector with a documented 400 ANSI-lumen rating, Android TV 9, Google Play access, and autofocus. The evidence chain matters: Anker's support page identifies Solar Portable and links a D2131 document; the manufacturer manual explicitly covers D2130 and D2131; Anker's Solar specifications give the shared product figures used here. That supports a useful image and app profile without guessing runtime. The reviewed manual does not establish an internal battery or a three-hour battery claim, so verify power requirements for the exact unit before planning an outlet-free movie. Its projection distances are conventional, and its moderate output is best considered for controlled light.
Portable-style home viewing where Android TV and Full HD matter and the setup can be powered from a verified source.
It is not for buyers who require a verified battery runtime, a bright-room ANSI threshold above its stated rating, ultra-short-throw placement, or native 4K detail.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Anker's Solar specifications give native 1920 × 1080 and 400 ANSI lumens.
- Android TV 9 and Google Play provide a documented built-in app platform.
- Autofocus and a portable product designation support flexible home placement when power is confirmed.
What to weigh up
- The reviewed D2131 manual does not establish an internal battery or a runtime.
- At 400 ANSI lumens, room darkening and a moderate image size are important practical considerations.
- The documented projection geometry is conventional rather than ultra-short throw.

What the features mean for you
Full HD gives the Solar a clear image role
Anker's official Solar specifications identify native 1920 × 1080 resolution. That provides Full HD detail for movies and video, while remaining below native 4K. The rating is tied to the Solar model family; the D2130/D2131 manufacturer manual explicitly covers both model numbers and the Soundcore support page identifies D2131 documentation for Solar Portable. Those sources are the basis for connecting the model details. Check the exact label and firmware on the unit, especially if a seller uses a generic Solar name. Native resolution describes pixel count, not brightness, screen suitability, or battery life.
Plan around 400 ANSI lumens and room light
Anker rates the Solar at 400 ANSI lumens. The clearly named method supports comparison to other ANSI-rated models, but it is a modest output for a projector used in ambient light or at a very large screen size. A darker room and a restrained image size can make more sense than expecting it to overpower daylight. Lamp hours are not the issue described for this model, but the individual unit's condition and image uniformity still need inspection. Do not treat the 400-lumen figure as a current measurement of used hardware or promise of equal brightness in every mode.
Use Android TV as the documented app route
Anker lists Android TV 9 and Google Play for the Solar, which establishes an onboard app environment rather than merely wireless screen mirroring. App availability can change over time and may depend on service support, software, and account setup, so confirm the exact interface if a particular service is essential. HDMI 2.0 and USB-A provide external-device options when an app does not suit the household. Built-in apps reduce extra hardware, but they do not establish cordless operation. Keep the power plan separate from the streaming question and test the desired service before relying on it for an event.
Treat portability and battery runtime as separate facts
Anker calls the product Solar Portable, which supports a portable-use category, but the reviewed manufacturer manual does not establish an internal battery or runtime for D2131. Do not carry over a runtime claim from the historical candidate title. Confirm whether the exact unit includes a battery and how it is charged before planning an outdoor or outlet-free session. A portable chassis can still be used in a powered room. The supplied manual and model label should guide practical setup; check the adapter, connectors, autofocus, Wi-Fi, remote, and actual operating behavior before relying on a used unit.
Measure the screen distance and view the actual image
Anker's Solar specifications include projection distances for conventional image sizes, and the source does not describe an ultra-short-throw lens. Measure lens-to-screen distance and compare the desired image size with the manufacturer's table before settling on a shelf. The projector's autofocus can simplify sharpness adjustment, but it does not move the optical image or replace careful positioning. Check focus across the whole image, color uniformity, and keystone after the unit warms up. If a close-wall installation is the main constraint, choose a projector with a verified UST ratio instead of inferring one from the compact Solar Portable name.
What else to compare
Compare WANBO TT if built-in named apps and 650 ANSI lumens matter more than portability, or RCA RPJ140 if local disc playback is the priority.
