Leaky Batteries
2010-07-06Rapid Charger is a little big to be travel portable in an age where carry on space is at a premium. However, the biggest problem is the batteries themselves started leaking within 6 months of purchase. This doesn't create confidence in the product. i wouldn't buy it again.
Don.t buy these batteries
2010-07-05These batteries only charged one time after that they would not hold a charge(we found out at my sons graduation,I wish I had brought extra batteries.)

An OK charger
2010-04-25The batteries it shipped with lost their ability to charge in about two charges. The charger itself is OK, but nothing special
Dead first time out
2010-04-18I bought this from Amazon for Christmas 2009 to accompany the digital camera I was giving my wife. The non-rechargable batteries we put in the camera lasted until April.

The next day, I put the batteries in the camera which immediately reported "battery exhausted". I feel like I wasted the money I spent.

Professional video camera
A Professional video camera (often called a Television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, direct-to-video movies, etc.
There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end camcorders) used for ENG and EFP image acquisition, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder.

Audio & Video Connections Guide
" For a list of all the ways technology has failed to improve the quality of life, please press three." - Alice Kahn
This quote is certainly applicable to consumer electronics. From the very first commercially produced radios to the latest in high-definition television technology, the manner in which the components used to deliver our news, music, movies and entertainment are interconnected seems to have escaped logic. For both the newcomer and the old hand alike, connecting equipment in the most efficient and effective manner can be a painful chore. It is hoped this article will improve your background knowledge concerning potential A/V system connection schemes and where each is most appropriate. The next time you find yourself in a "connectivity quandary" perhaps the ideas shared here will help you to quickly solve the riddle of which wire goes where and why!
