This is reviewed as the best Mini portable TV projector. Simply connect your phone to it and point it at a wall, or screen if you have one. If pushed this little guy to 120 inches and it took it with a clear bright picture. I recommend you stick to about 80 inches. The Apeman M4 retails for over 200.00. You must buy a connector that allows your phone to input to the M4. It retails for about 30.00. It was used twice so it’s as new. Travels light. You can put this thing in your pocket! Runs for a couple of hours on battery or just plug it in. 230.00 value, selling the M4 and HDMI to phone adapter for a great price hurry this won’t last long. Tv projection is the hottest thing going in today’s A/V arena.
