If you want to show videos or presentations at any location, you should go for the LG PF50KS. This mini-projector has an integrated battery that will last for up to 2.5 hours. Put the device in your bag and use it anywhere, even if there's no socket nearby. If you connect the projector to the Internet via WiFi, you'll have access to the smart TV functions. This allows you to watch videos online from apps such as YouTube. If you'd rather display images from a USB flash drive or external hard drive, that's not a problem, thanks to the integrated media player. Whatever you're watching will be displayed sharply, thanks to the Full HD support. This means that letters, numbers, or other small details will be clearly visible.
