The correct unit for measuring energy capacity of a battery product is called watt-hours. Watt-hours signifies that a battery can supply an amount of watts for an hour. For example, a 60 watt-hour battery can power a 60 watt light bulb for an hour. The same battery would run a 5W phone for 12 hours and power a 1W LED light bulb for 60 hours.
On the back of your appliance, you will find a label describing the power requirements. You should see a label describing the Wattage (W) or the Amperage (A) of the appliance. Once noted, choose a voltage transformer / converter which can handle a higher amount of wattage then your device is rated at.he difference is the type of battery you want to run your power inverter on. Most vehicles run off a 12 volt battery. The 24 volt are generally used in large trucks or industrial motors. For more information please visit PowerBright.com.
