So how do you measure current? Kill A Watt? or multimeter + shunt
resistor?

Before getting the Kill-A-Watt I use now, I used a multimeter with a
homemade adapter for measuring current. It was safe as long as it was
connected to the meter first. Anyway, I never used it outside or anywhere
near water.

So basically just a shunt resistor. Like, say, 1-2 ohms, 10-20 watts.
Plus a plug-and-socket arrangement. I should try that sometime. The poor
man's Kill A Watt.



I didn't add a shunt resistor, the meter already had one. Before selecting
that meter, I looked for one with a 10A range for measuring the current
consumption of devices.
