It will follow charged MP3450I after loading's internal battery hascharged fully. The MP3450I also will be charged fully at finally. It will total charged fully after7~8h by connected as this diagram. if empty of all battery ( MP3450I& loading's internalbattery). It doesn't matter the loading device is operated or not . It will auto stop chargingMP3450I battery.while offer to device's loading current higher than 2±0.2A. ; it will startcharging MP3450I if device's loading current less than 2±0.2A. The loading device demandpower always priority one of support from AC Power adapter.3.Outdoor application ————Back-up power for your device:Please check loading device demand voltage/current before connected the DC OUT port ofMP3450I. It will shut down if demand current over MP3450I maximum output 4.5A.     Packaging & Shipping    V.Packing accessories:     VI. Product clear picture:
