This is solely from my perspective using both an Android cell phone and tablet, and with input from Kenny.
The new camera (green or orange) will afford better focus and clarity.
Any typical 5v computing charging device or battery power pack will fuel up the 3.6v batteries in the camera or the separate battery pack for the base station as the camera and base station have internal voltage regulators for their 3.6v power supply needs.
When using the camera for long range viewing, the 18650 batteries have a limited life span of 2 hours or less. I found that out the hard way. (Edit - a power pack has worked out best for me, see my post further down in this thread).
When viewing the connection in your computing device, "Eagle Target Cam xxx" is the camera and "EAGLE TARGET CAM STATION" is the base station. If you connect to the camera while downrange at the target, you'll need to connect to the base station when you're back at the shooting bench!
From Kenny - Do not press the reset button on the base station as it may result in the base station to default. The slide switch next to the base station reset button is for future use in as possible weather station.
More pearls of Eagle LR Target Camera wisdom may be added to this topic.
The current model has upgraded batteries equivalent to the amp hour capacity of the Samsung 50E. We recommend to not connect to the camera unit itself and connect using the WiFi base station at all times. This will alleviate your viewing device from auto connecting to the camera at 150 yards and in. If you have connected to the camera before, hit the (i) icon on iPhone and delete connection, on Android hit the gear icon and click forget network.
