On the left side of the unit you'll find the dual earphone jacks as well as the AV input (for using the player's screen as a monitor) and output jack (for playing DVDs on a larger TV), for which Panasonic includes the necessary AV breakout cable. Also in the box is a power supply and a car charger--but you won't find any accessories to mount the LS83 on a car seat headrest. The only accessory we wish Panasonic would have included is a remote control. We know the idea of a remote for a portable player seems trivial, but the majority of players we've seen recently all include one.
In terms of performance, the DVD-LS83 works well. We weren't overly impressed with the video quality; we'd have to label it as just average compared with the other players we've tested. We were happy to see that the LS83 had no problem playing our DivX-encoded video files, MPEG4 videos, MP3 and WMA audio files, and JPEG photos. However, you'll need to burn all of these files to a disc (DVD-R, DVD-RAM, or CD-R); had Panasonic added a USB port or flash card reader, the digital file support would've been far more attractive and convenient. Sound quality from the two onboard speakers was good, but like with all portable devices, you'll probably be using headphones in most viewing situations.
The battery rests below the screen's hinge and doesn't protrude excessively from the player's body. Panasonic claims the device will give you 6 hours of playback after a normal charge, and we found in our testing that this was spot on. It's worth noting that the step-up model, the Panasonic DVD-LS86, is essentially the same player that promises up to 13 hours of playback, but in our testing it yielded only 9.
