    Understanding battery capacity: Ah is not A

    - 5 October 2014

    Hi Jan,
    Thanks for you explanations. I have an musical device (TC Helicon Harmony Singer) with tech specs: Power Supply (Supplied): 12V .4A ; Power Consumption: 5.6W. I want to use with mobility, so need some sort of battery power supply. I cam across a 12V 4800mAh Rechargeable Portable Emergency Power Li-ion Battery.
    With tech specs:
    - Capacity: 4800mAh
    - Voltage: DC 12V
    - 110~240V 2-flat-pin plug power adapter
    - Provides emergency power supply for devices with 12V power source
    Have I made the right choice and can you give an indication of how many hours I can use it before I need to recharge? Will it last for 4 hours in a row? Thanks for your reply!
    Jerry
