Specs are from the official soundcore (Anker) product pages, checked 23 Oct 2026. Nebula is Anker's projector brand, now sold under the soundcore name.
Plenty of Airbnbs and home-stays have a small TV, an awkward login screen or no TV at all, yet almost all of them have a blank wall. A battery-powered smart projector turns that wall into a big screen for a family film night or a rainy evening, and it packs into your luggage. All three picks come from Nebula, Anker's projector line, and all three run Google TV and auto-adjust the picture in seconds.
soundcore Nebula Capsule 3 Laser: the best all-rounder
soundcore Nebula Capsule 3 Laser
- 300 ANSI lumens laser light source
- 1080p
- 52Wh battery: up to 2.5 hours of video
Best for: Carry-on travellers who want a bright picture from a can-sized projector
Check priceThe soundcore Nebula Capsule 3 Laser uses a laser light source rated at 300 ANSI lumens in 1080p, and Anker says it's almost twice as bright as current LED projectors, with HDR10 support. It projects up to 120 inches and measures 3.3 x 3.3 x 6.7 in, about the size of a drinks can. Anker lists the weight as both 2 lb (900 g) and 2.1 lb (950 g) on the same page, so expect about 2 lb.
The 52Wh battery gives up to 2.5 hours of video or 8 hours of music. It supports PD charging, so you can top it up from a power bank. You get Google TV, Google Assistant, Google Cast and officially licensed Netflix, plus an 8W Dolby Digital speaker. Autofocus and auto keystone sort the picture out in about 3 seconds, Anker says.
Specs
- 300 ANSI lumens laser light source, 1080p
- 52Wh battery: up to 2.5 hours of video
- Google TV with licensed Netflix and Chromecast
What we like
- Brighter than the LED Capsule 3 in almost the same footprint
- Power-bank charging over PD for picnics and balconies
Watch out
- Still a projector: it looks best with lights off and curtains closed
Who it's for: Airbnb travellers who want one projector small enough for a carry-on and bright enough for a living room.

soundcore Nebula Capsule 3
- 200 ANSI lumens
- 1080p
- 40-120 in image
Best for: Couples and solo travellers watching in a dark bedroom
Check priceThe soundcore Nebula Capsule 3 is the lightest pick at 0.85 kg, measuring 78 x 78 x 160 mm. It's 1080p at 200 ANSI lumens, with a picture from 40 to 120 inches. Nebula's spec sheet lists an RGB LED light source rated for 30,000 hours.
Battery life is up to 2.5 hours in Eco Mode, and it charges over USB-C PD (20V/2.25A). You get Google TV with licensed Netflix, Chromecast casting, an HDMI 2.1 (ARC) input for a laptop or console, and an 8W Dolby speaker. Like the others, it performs screen fit, auto keystone, autofocus and obstacle avoidance in about 3 seconds.
Specs

- Up to 2.5 hours (Eco Mode); PD 20V/2.25A charging
- 0.85 kg; 78 x 78 x 160 mm
What we like
- Smallest and lightest here
- Charges over USB-C PD (20V/2.25A)
Watch out
- 200 ANSI lumens is the dimmest of the three, so plan on a dark room
Who it's for: couples and solo travellers who watch in the bedroom and value pack size over brightness.

soundcore Nebula Mars 3 Air: the group movie-night pick
soundcore Nebula Mars 3 Air
- 400 ANSI lumens
- 1080p HDR
- 30-150 in image
Best for: Families and groups renting a whole house or villa
Check priceThe soundcore Nebula Mars 3 Air is a bigger box, 178 x 122 x 133 mm and 1.693 kg, but it's the brightest here at 400 ANSI lumens with 1080p HDR and a 30 to 150-inch picture. Dual 8W Dolby speakers make it the best pick when six people are watching in a villa lounge, and it doubles as a party speaker.
Anker lists up to 2.5 hours of video or up to 8 hours of music per charge. It has the same Google TV, Netflix and Chromecast package, an HDMI 2.1 (ARC) input, a noise level under 28 dB, and Nebula's 3-second auto setup with obstacle avoidance.
Specs
- 400 ANSI lumens, 1080p HDR, 30-150 in image
- Dual 8W Dolby speakers
- Up to 2.5 hours of video; 1.693 kg
What we like
- Brightest picture and biggest sound of the three
- Biggest maximum screen size
Watch out
- About twice the weight of the Capsule 3, so it's more one for a checked bag
- Anker lists a 19V/4.74A power input, so pack its own adapter
Who it's for: families and groups booking a whole house who want a proper big-screen night.

How to choose a projector for Airbnb stays
- Brightness vs bag space. 200 ANSI lumens suits a dark bedroom, 300 a living room with curtains, and 400 a bigger room or a group.
- Check the wall. A plain, light wall works. A bedsheet or roller blind can help in a pinch.
- Use casting, not the host's logins. Built-in Google TV and Chromecast mean you sign in on your own device, then sign out before checkout.
- Plan for the Wi-Fi. Streaming needs a decent connection. If the host Wi-Fi is weak or has a login page, a travel router can help. A travel eSIM such as Airalo is a useful backup for casting a short show (our travel eSIM guide). Watch your data allowance, as video uses a lot.
- Think about power. The Capsule 3 and Capsule 3 Laser charge over USB-C PD, so a suitable USB-C PD charger or power bank can top them up.
- Cover your kit. A projector is a valuable item to travel with. Check your policy's gadget limits (our travel insurance guide).
Our verdict
For most Airbnb and home-stay travellers, the soundcore Nebula Capsule 3 Laser is the one to pack. It's a laser-bright 300 ANSI lumens in a can-sized, roughly 2 lb body, with a 52Wh battery and power-bank charging. If pack size matters most and you'll watch in the dark, the Nebula Capsule 3 is the smallest and lightest. For a family villa or a group trip, the Nebula Mars 3 Air brings the brightest picture and the biggest sound.

FAQ
Can I use a portable projector without the Airbnb's Wi-Fi?
Yes, for local content. The Capsule 3 and Mars 3 Air list an HDMI 2.1 (ARC) input for a laptop or console, and Anker says the Capsule 3 Laser has a variety of ports. Casting and streaming do need a network. Your phone's hotspot or a travel eSIM can stand in if the Wi-Fi is weak.
Do I need a screen?
No. A plain, light wall works well, and all three autofocus and auto-keystone the image.
How long does the battery last?
Anker lists up to 2.5 hours of video for all three; for the Capsule 3 that's in Eco Mode. That's enough for most films, and you can keep them plugged in for longer sessions.
Is Nebula an Anker brand?
Yes. Nebula is Anker's projector line, now sold on soundcore.com as "soundcore Nebula".
