The Pyle PLMN7SU 7" Battery Powered TFT/LCD Monitor works great in or out of your vehicle, thanks to the built-in two hour rechargeable battery. Connect a DVD player, video game system, rear view camera, or any other device over the AV input port. This monitor can also play audio and video files from SD, MMC, MS and mini-USB inputs. Built-in stereo speakers allow you to watch your favorite videos without headphones, or go private by plugging in to the standard headphone jack. A super-thin wireless remote control is included to control playback and adjust monitor settings remotely.
