Convert VOLTS-AMPS to Watts at alternating current (AC)
Enter the total power in volts and click "Calculate" to get the actual power in Watts.
The actual power P in Watts (W) is equal to the total power S in volts-amperes (VA) multiplied by the power factor PF.
P (W) = S (VA) × PF (0.7)
Service life of the device, taking into account the level of safe discharge of the battery
To do this, specify:
- Device power (Watts)
- Battery capacity (Ampere-hours)
- Battery voltage (Volts)
- Acceptable discharge (%)
By default, the calculator sets the maximum discharge value recommended by the manufacturer (conservative 50% by default) of battery capacity.

What battery capacity is needed for the device to work for N-hours
To do this, specify:
- Device power (Watts)
- Set the Working Time (Hours)
- Battery voltage (Volts)
- Acceptable discharge (%)
By default, the calculator sets the maximum discharge value recommended by the manufacturer (conservative 50% by default) of battery capacity.
