Very small sample (152 ratings).

CNET's pick for the smallest useful projector: the size of a soda can, with full Google TV and a built-in battery. It's very dim (84 lumens measured), only 720p and not color-accurate, and Amazon owners are split on brightness, setup and sound.

Top complaints

  • Very dim

    CNET measured 84 lumens (150 claimed). Anker recommends 30 to 80 inches, and at 100 inches the projector keeps asking you to move closer. Amazon's summary says some owners find the brightness insufficient.

  • 720p and inaccurate color

    CNET lists 'not very accurate' as a con and notes the 720p resolution when most projectors are 1080p or 4K.

  • Mixed setup and sound experiences

    Amazon's summary says setup and sound get mixed reviews, from easy setup to an 'infuriating' one, and crackling sound after three months of light use. Autofocus and value also get mixed reactions.

What owners love

  • Truly pocketable

    About the size of a beverage can (CNET). Amazon shoppers praise the compact size and say it's easy to take anywhere.

  • Full Google TV and flexible power

    Full Google TV, an HDMI input, autofocus, and USB-C charging that can run from a 45 W power bank (CNET).

  • Good contrast for its size

    CNET measured 381:1 contrast, double the original Capsule and better than some larger, pricier projectors. It also works as a Bluetooth speaker.
