Watching your favorite movie on a big-screen TV is great, but most TV sets these days top out at 70 to 80 inches in size. If you want to cast the action on an even larger screen, you’ll want to invest in a good projector.

While some projectors can run you thousands of dollars (especially newer 4K projectors), Amazon has a number of portable projectors available for way less than you think.

Their current best-seller is this mini projector from AuKing, which boasts a 4.3-star rating (out of five) from more than 13,000 verified reviewers. Even better: it’s discounted to just $57 right now as part of October Prime Day — that’s a 42% discount and one of the best portable projector deals online.

Newly released for 2024, the AuKing portable projector delivers your content in full HD resolution with 9500 lumens of brightness for clear, detailed images that always stay in focus. Even better: the shoebox-sized projector can cast a screen up to 200 inches in size, making it a great pick for sports, gaming or movie night at home.

This mini projector comes with built-in speakers that are surprisingly loud for its size (you can also connect it to an external set of speakers to boost the volume even more). Improved noise reduction technology keeps the projector running smoothly without that annoying buzzing or whirling sound.

Lamp life is great, at up to 55,000 hours, and AuKing says you should be able to use this projector for up to 15 years.

This portable projector features an HDMI, VGA, AV, and USB output, so you can connect it to your phone, USB drive, gaming console and more. It stores easily thanks to its small size and it comes with a two-year warranty in case you run into any problems. It’s light enough to transport with you (say from home to party) but it’s durable enough to not topple over.

This Amazon projector deal gets you the AuKing portable projector, a remote control, power cord, HDMI cable, AV cable and user manual for just $57. Regularly $99+, the deal saves you 42% off one of the most popular mini projectors online.

Keep in mind that this is best-suited for indoor use and the projector works best in dark rooms (your image won’t be as clear in bright rooms or during the daytime). This is also an HD 1080p projector; if you want the sharpest, crispest images, you’ll want to upgrade to a 4K projector like this model, on sale for just $189.99 on Amazon here.

Amazon says more than 2,000 people have purchased this projector in the last month alone, with reviewers giving it a 4.5-star review (out of five) from more than 4,000 verified reviews online. See full details here.
