Measures:

# Cumulative kWh over time (using built in timer)
# Watts (active power)
# VA (apparent power)
# Volts
# Current (amps)
# Frequency (hertz)
# Power Factor

1875VA limit
15 A limit.

I googled a review that said it showed 0.06 kWh after 2 hours for a TV.

I'd imagine the utility co's unit has a higher amp rating.
