Best Battery-Powered Projectors in 2022: BenQ, Anker and More

You don’t need bulky gear or a big budget for a big screen. With a small portable projector you can have a movie night inside a pillow fort, in the backyard or even out in the wilderness. The best options can fit easily in any backpack, and some are small enough to fit in your pocket. 

Whether you project onto a blank wall or a projector screen, you can capture the picture quality you crave without getting weighed down. They also offer a handful of connectivity options including HDMI and Bluetooth, and they typically run on batteries. Many mini projectors are set up to stream, giving you access to Netflix, Amazon Prime Video, Disney Plus, Hulu and other streaming services without having to connect another device.

Portable projectors do come with a few drawbacks, though. One is that many are relatively dim, lacking the brightness of a traditional home theater projector, meaning they can’t project as large an image as the big guys. Another is that even the best portable projectors often have lower resolution than their larger counterparts. If you’re never going to be far from an outlet, a standard projector will get you a much bigger, brighter and better image for similar money. But if you want something compact, portable and battery-powered, here are our top picks for the best portable projector.

The Mars II Pro is the best compact projector option here due to its light output, overall image quality, ease of use and affordable price. This mobile device is a bit bigger than most other portable projectors here, but still small enough to hide completely under a six-pack of Coke.

The built-in 12,500-mAh battery is good for about 3.5 hours, longer if you just run it as a Bluetooth speaker. There are apps built in, some of which consider the Mars II a portable device, meaning you can download content to its 8GB internal memory for offline watching. The faux-leather strap also makes carrying the outdoor projector around super easy.

I like the top projector better but the AAXA P6X is my pick when money is tight. Not only less expensive than the Anker above, it’s also brighter with superior battery life. This mini projector fits in my hand, creates a 720-pixel image, and has a huge 15,000-mAh battery. An HDMI input and USB connection lets you connect and power a streaming stick. The stick connection is important because the AAXA lacks built-in apps. 

Light output is impressive for its size and price, about 50% more than the Anker Mars II Pro, though its contrast ratio is a bit less. The internal battery should last around 90 minutes in the mini projector’s brightest mode, and an impressive 240 minutes in ECO mode — probably a little less if you’re also powering a streaming stick. The internal speaker isn’t great, but there’s a headphone jack you can connect to a portable speaker.

While we didn’t like it quite as much as the BenQ GS50, this small, flat Anker mini portable projector costs less. Its main disadvantage compared to others on this list is its relatively dim image, which means it can’t project as large a picture and still look good. If you want a sleek, budget-friendly portable with 1080p and plan on keeping the image on the small side, however, this is a solid choice.

The Anker Nebula Capsule is smaller than a can of soda, but can create a big image. Well, maybe not “big,” but “TV-sized” certainly. It’s not particularly bright, nor loud, but for something that can fit in your pocket it’s great. The other options here offer a far brighter, better image, but if size is your main concern, the Capsule looks better than you’d expect for its price and stature.

Although it costs more than the Anker Mars II Pro, this BenQ has more accurate color and a better picture overall. With 1080p resolution, compared to the Anker’s 720p, you’re less likely to see pixel structure or a “screen door effect” when watching from close up or with a really big image screen size. In most cases, however, 720p is just fine, making the Anker a superior value.

While the GS50 is unavailable via Amazon as of right now and only available on special order from B&H, you can sign up for inventory notifications from BenQ here.

Other products we’ve tested

LG CineBeam PH30N: The LG PH30N is tiny even compared to other portable projectors, even smaller than the AAXA. It’s not particularly bright, however, nor does it have built-in apps. The battery doesn’t last as long as the AAXA either although it is a bit cheaper. Read our LG CineBeam PH30N review.

Samsung Freestyle: The small, cylindrical Freestyle is an interesting idea, but it comes up short. About the size of a Bluetooth speaker, and in fact can double as one, the Freestyle can pivot on its stand to project an image at any height on walls and even the ceiling. Its built-in streaming is far better implemented than most portable projectors. However, it lacks a battery and its performance is average, at best. Worse, its price is a good 50% higher than it should be based on how it looks and performs. Read our Samsung Freestyle review.

BenQ HT2050A: The HT2050 isn’t technically a portable projector, but it is compact and roughly the same price as one of the more expensive “portable” options. Its picture is also much better in pretty much every way, so if you’re looking for a projector for use around the home, or maybe backyard, and you don’t need battery power, it’s worth considering. Read our BenQ HT2050A review.  

Epson Home Cinema 2250: Like the BenQ HT2050A, Epson’s HC 2250 is an excellent home theater projector. It performs about the same as the BenQ, but is better in some ways and worse in others. Again, it’s intended for in-home use, but is small enough to put on a shelf or in a closet when not in use and will look better than any of the projectors on this list.

FAQs

What makes a mini projector different from a full-size projector?

The biggest difference is light output. Traditional, full-size projectors can get much brighter than any portable mini projector. Most portable projectors use an LED lamp, while full-size projectors have either UHP lamps (which are basically high-powered light bulbs) or laser light sources. Projector light output is measured in lumens. The brightest portable projectors we’ve reviewed measure about 350 lumens, while a traditional home theater projector measures 1,500 lumens or more. 

A bright projector can produce a larger image, and looks better when there’s some ambient light around. For that reason dimmer portable projectors are best enjoyed with smaller images and in as dark an environment as possible.

Beyond brightness, mini projectors are much smaller (of course), can run on battery power and usually include built-in streaming and decent speakers. Traditional projectors have more lens adjustments, including focus, zoom and lens shift, and can run louder. 

Does a mini projector have to be plugged in?

It depends. Many portable projectors have built-in batteries that can run for two or three hours before needing to be plugged in. Some can also attach to external USB battery packs that allow them to be run without plug-in power. On the other hand, many smaller portable projectors, especially cheaper ones, don’t include a built-in battery or work with battery packs. They will need to be plugged in to work.

Can you watch Netflix on a portable projector?

Yes. Many mini projectors have built-in streaming that allow them to show Netflix and other streaming services when connected via Wi-Fi. For projectors that don’t have built-in streaming, you’ll need to connect another streaming device, like a Roku or Fire TV Stick, to the projector’s HDMI input to stream Netflix and other services.
