Tiny, pocket-size projectors -- often referred to as picos -- have had a bumpy start on the market, but they've started to hit their stride, as evidenced by Brookstone's $300 HDMI Pocket Projector. Although it has some drawbacks, they're fewer and less severe than those of previous models I've reviewed, which makes this one of the better pico options -- for the moment anyway.
One of this projector's big strengths is its design. Measuring 0.89 inch by 3.9 inches by 3.8 inches (HWD), it weighs around half a pound and is truly pocket-friendly so long as you aren't wearing tight pants. It's about the same size as an Apple TV streaming-media box.
Sitting there alone, the projector looks quite sleek with its glossy, slate-colored finish (yes, you'll have to wipe the fingerprints off after handling it if you want to keep it looking shiny).
It's a shame it has to be cluttered up with cables and power adapters, but it does have a built-in rechargeable battery that delivers about 2 hours of battery life. A USB port on the back can be used to charge a smartphone, and there's also an auxiliary input for adding an optional speaker to augment the sound.
The projector does have two built-in 1-watt speakers that produce enough sound to make your videos watchable, but even a tiny wired or wireless speaker will deliver significantly more sound. I combined the JBL Micro Wireless Bluetooth speaker with the unit and it really improved the movie-watching experience.
Around back you'll also find an HDMI port, which is not surprising considering this is called the HDMI Pocket Projector. Obviously, you can connect the projector to any video source that has an HDMI-out option; Blu-ray players, as well as many smartphones, tablets, and laptops, would fit the bill.
To help pair your device with the projector, Brookstone includes a couple of adapters for smartphones and tablets along with a short HDMI cable. I got it working with a Kindle Fire HD, a Blu-ray player, and an Android phone. But if you own an Apple device, you'll need an Apple Digital AV Adapter -- that's $40 for the 30-pin version or $50 for the Lightning version. Alternately, you could hook an Apple TV box to the Brookstone, and wirelessly send video from an iPhone, iPad, or iPod Touch via AirPlay mirroring.
A couple of other small things worth mentioning: There's a threaded hole on the bottom of the projector, so you can mount it or attach it to a tripod. Also, you focus the picture using a small ring on the left side of the device. It isn't terribly precise -- and it takes some fiddling around to get the correct focus -- but it works.
Brookstone includes a cheap nylon sack to store the projector in. It will prevent the device from getting scratched up, but otherwise it provides minimal protection.
