Sometimes, smartphone screens are just not big enough. Linking it to a projector is helpful but it's hardly portable and before you know it, the battery's gone. The Monolith, a triple-threat iPhone case that works as a projector and a battery pack, can light up your room while keeping your gear booboo-free.
The case, made by Japanese accessory maker Century, is said to be capable of providing about three hours of image projection at sizes up to 60 cm (in 16:9 format), in 640×360 resolution, with a 1,000:1 contrast ratio. But with a brightness of a mere 12 lumens, it's certainly no makeshift movie theater. At best, you'll probably end up using it for a viral video party … if you're entertained by three hours of that stuff.
If you are (and I'm not judging you!), you won't have to worry about killing your battery life; the 1,900 mAh battery will either cancel out the drain or boost your iPhone's lifespan up to 50 percent without projector usage and takes four hours to fully charge. For $260, it's a pricey battery pack, but you can decide whether the novelty of having a handy projector is worth the investment.
