The Nebula by Anker Capsule 3 1080p Laser Projector is a compact, can-sized projector aimed at anyone who wants a big-screen experience without dedicating a whole room to it. With a 1080p laser light source, built-in Google TV and Dolby Audio, it is clearly positioned as a premium portable rather than a basic travel gadget.
Its 300 ANSI lumens brightness and 120-inch maximum screen size make it best suited to dim rooms or evening viewing, but the combination of Full HD resolution and laser tech promises a noticeably sharper, cleaner picture than cheaper LED options. Weighing around 2 lb and running on battery for a full film, it is designed to go from living room to bedroom to garden with minimal fuss.
User scores are strong, sitting at 4.5 out of 5 from a growing number of reviews, suggesting that most owners are very happy with the blend of portability, picture quality and smart features – even if the price is on the higher side for a casual projector.
The Capsule 3 is ideal for film lovers and box-set binge-watchers who want a big screen without installing a ceiling mount or buying a bulky TV. If you like the idea of moving your movie night from the living room to the bedroom or even out into the garden, its compact footprint and built-in battery make a lot of sense.
It is a good fit for flat dwellers and smaller homes where space is tight. At just 17 cm tall and 8.3 cm wide, it is easy to tuck on a shelf or carry in a bag, and the 120-inch maximum screen gives you a cinema-like experience without a permanent installation.
The price and spec put it in the premium portable bracket rather than entry level, so it suits buyers who are happy to pay more for laser picture quality, a proper smart TV interface and Dolby Digital sound. First-time projector buyers who want something simple will still find it approachable thanks to Google TV and voice control, but it particularly suits tech-savvy users who appreciate having all their streaming apps built in.
It also works well for occasional work use – think presentations in dim meeting rooms – but its strengths are clearly home entertainment, especially streaming platforms like Netflix, Disney+ and YouTube that are supported out of the box.
The standout strength is image quality for the size. Full HD 1080p resolution on a laser DLP engine means sharp, detailed images with more consistent brightness and a rated 30,000-hour light source life, so there are no bulbs to replace for years of normal use.
Portability is excellent. At around 2 lb and roughly the size of a large soft-drink can, it is genuinely easy to move room to room or take to a friend’s house. The built-in battery offers about 2.5 hours of video playback – long enough for most films – and USB-C PD support means you can top it up from a power bank when you are away from mains power.
The integrated smart platform is a big plus. With Google TV, built-in Google Assistant and official Netflix support alongside Prime Video, Disney+, YouTube and more, you can stream directly without plugging in a laptop or streaming stick. Chromecast support and Bluetooth round things out for wireless casting and audio.
Sound quality is better than most portables thanks to the 8W Dolby Audio speaker. While it will not replace a dedicated sound system, it delivers surprisingly full and clear audio for casual viewing, making it a true all-in-one cinema that does not demand extra speakers.
Ease of setup is helped by automatic horizontal and vertical keystone correction, so you have more freedom in where you place it and can still square off the picture without fiddling endlessly with menus.
At 300 ANSI lumens, brightness is respectable for a portable, but it is not designed for bright, sunlit rooms. For the best results you will want curtains drawn or evening lighting, especially if you are pushing towards the larger end of the screen size range.
The price is on the premium side for a compact projector, and the specification includes just 16GB of internal storage and 2GB of RAM, which is enough for apps but not generous. There is no memory card slot, so you cannot expand onboard storage for offline media.
Connectivity is stripped back: you get one HDMI 2.1 port and a single USB-C port, with no Ethernet (wired network) option and no DVI. For most users HDMI and Wi-Fi will be fine, but wired-network fans and those wanting to hook up lots of external devices may find it limiting.
Finally, the warranty is only one year, which feels modest at this price point, and there is no built-in microphone on the unit, so you will rely on the remote for Google Assistant voice control rather than hands-free commands.
Day to day, the Capsule 3 feels more like using a small smart TV than a traditional projector. Once it is charged, you can simply plonk it on a table, power it on and be into your streaming apps within moments. The cylindrical shape is easy to grip and move, and there is no heavy power brick to wrestle with for short sessions on battery.
The auto keystone correction in both horizontal and vertical directions makes setting up the image far simpler than older projectors – you do not need perfectly straight placement to get a tidy rectangular picture. The 1.2 throw ratio means you can get a decent-sized image from relatively close to the wall, which suits smaller UK rooms.
Sound from the 8W speaker is impressively clear for spoken dialogue, and casual music or sports soundtracks have enough body not to feel tinny. For bigger movie nights you may still prefer to pair it with a Bluetooth speaker or soundbar, but you do not have to, which keeps things uncluttered.
Because it is a smart projector with Google TV, you control almost everything from the bundled remote – switching apps, searching with Google Assistant, adjusting settings. There is no built-in display on the device itself, so menu navigation will always be on the projected image, but that keeps the hardware clean and simple.
Charging takes around three hours for a full battery, and the maximum rated battery life of up to 10 hours applies to lighter tasks, with roughly 2.5 hours for continuous video playback. That is typically enough for a film and some trailers without needing to plug in midway.
The core performance story revolves around the 1080p DLP laser engine. Full HD is still the sweet spot for portable projectors, offering a crisp picture that flatters HD content from Netflix, Disney+ and Blu-rays. The laser light source gives more stable brightness and colour over its 30,000-hour rated life, which easily covers years of daily use without maintenance.
Brightness at 300 ANSI lumens is well judged for portable use. In a dim room, images up to around 100–120 inches remain punchy and detailed, while colours stay reasonably vibrant. It will not compete with a high-end home cinema projector in a fully lit room, but that is not its aim – think cosy film nights rather than daytime sports in full sunlight.
Smart features are a real highlight. With Google TV, you get a slick, modern interface, personalised recommendations and quick access to major streaming services including Netflix, Prime Video, Apple TV, Disney+ and YouTube. Google Assistant built in means you can search for films, launch apps or adjust basic settings by voice through the remote, and Google Cast support lets you cast content from Android phones, Chrome browsers and compatible apps with minimal fuss.
On the hardware side, a quad-core processor running at 2.1 GHz and 2GB of RAM keep the interface responsive, and 16GB of internal storage is enough for core apps and updates. Wireless connectivity includes Wi-Fi and Bluetooth, so you can pair headphones or speakers, or use it as a Bluetooth speaker when you are not watching video.
Connectivity ports are simple but modern: one HDMI 2.1 input handles consoles, laptops and media players, while the USB-C port deals with power and some compatible devices. There is no Ethernet jack, so you rely on Wi-Fi for streaming, but for most home users with a solid wireless network that will not be an issue.
This is clearly positioned as a premium portable projector rather than a bargain option. You are paying for a combination of 1080p laser picture quality, genuinely compact design, an integrated smart TV platform and Dolby Audio in a single neat package.
If you only need a basic projector for occasional presentations or do not care about portability, you can certainly find cheaper models. However, many of those will use dimmer LED light sources, lower resolutions or require an external streaming stick, and may not come close to the Capsule 3’s all-in-one convenience.
The strong owner rating of 4.5 out of 5 suggests that most buyers feel they are getting fair value for what they spend, especially given the long-life light source that should minimise running costs over time. The main caveat is the relatively short one-year warranty, which is a little lean at this price and slightly tempers its value proposition.
Overall, for someone specifically shopping for a compact, battery-powered projector with built-in streaming and good picture quality, it represents solid value – not cheap, but justifiable if you will actually make use of its portability and smarts.
The Nebula by Anker Capsule 3 1080p Laser Projector delivers a very compelling portable cinema experience. Its combination of Full HD laser projection, genuinely pocketable design, integrated Google TV and capable Dolby Audio speaker makes it one of the more refined all-in-one options for film nights at home or on the go.
It is not perfect: brightness is best suited to darker rooms, connectivity is fairly minimal and the one-year warranty feels short for a premium device. If you want a permanently installed, super-bright projector for a dedicated cinema room, your money may be better spent on a larger, more traditional model.
But if you value flexibility – movie nights in any room, streaming apps built in, and a big-screen experience you can pop in a bag – the Capsule 3 is a strong choice. For renters, flat dwellers and anyone who loves tech that simply works wherever you put it, it is easy to recommend.
