With the LG PH30JG, you can watch your favorite videos wherever you are. This mini projector has a compact size and an integrated battery. Fully charged, this battery lasts for about 4 hours. Put the projector in your bag and project images wherever you want, even if there's no socket nearby. You don't have to bring a Blu-ray player or laptop, because the projector has an integrated media player. This means that you can easily view images from a USB flash drive or hard drive. Thanks to the integrated speaker, you'll always have sound. If you want a movie or series to sound more powerful, then wirelessly connect the projector to a Bluetooth speaker.
