Review title: P4400 monitor
Product review: Works great does just what it says it will do. You will probably need an extension cord to see the read out in inconvenient places. My phone says unplug your charger when finished to save electricity, this thing told me my charger uses no electricity when unplugged from the phone, so now I don't have to think about unplugging it, that one piece of information was worth the price of this.
