How many Amps (A) will the machine give as output, provided it is fully charged and at what Voltage (V) normally?
The internal battery is rated at a nominal 12V and 7A HR. The battery maximum COLD CRANKING CURRENT is rated at 200A. Of course at such a high current the time is much shorter IE The battery will deliver 7A for about an hour, 14A for about 25Min etc. 12V is a universal output for many devices that need current. The 120w output is from the internal storage battery. There is always power available by using the foot input. This output can charge the internal battery or an external battery (if the internal battery is disconnected) at a power from 25 to 40 Watts. The amount of power available is dependent on how vigorously the foot pedal is operated.
