I am looking for a high capacity external battery for a Galaxy s4 which when plugged into the phone it does NOT need anything to switch it "on". When the phone needs power I need it to flow without any manual assistance. Many of these must be switched "on" which is an issue for me.Does anyone know where to but this type of external battery?

Pyro2448, I see in the pixs that there is an "on/off" button on the cover. Does power flow to a connected device WITHOUT pressing this button??? this is critical for my application. Maybe the button only controls the digital display (I am hoping).

You are correct that there is a power button,but it plays no role in actually turning the battery on and off, when you click it, it displays the amount of charge left in a percentage format as well as a battery level icon, if you hold down the power button it allows you to change the about of power to a device, I have mine set to 19.5 amps when I'm charging my laptop. Plug anything into it and it charges IMMEDIATELY with no need to power on the battery!

Thanks, this will work great. One more question. Do you know how this item will discharge when simply sitting on the shelf after a full charge? Appreciate the help.

Sorry I'm not fully understanding the question your asking?do you mean discharge as in nothing is plugged in or if your phone is plugged in how long will it last? Or do you mean its still plugged in and at 100%?
