2nd charge

With the meter on the correct screen, I see it uses 450w while charging, and 5w at rest. That seemed low to me until I thought about fuses blowing. Except fuses are measured in amps. At work we have a refridgerator that is listed at 7.5amps. We have two of them. When we tried three, on a 20 amp fuse, it blew if all three tried running at the same time.
I wrote down amp usage for the scooter, but don't have it with me.

1st charging notes

Charger started at 118 volts, but within 5 min was down to 117 volts. Before plugging in, was reading 12 volts.


UPDATE

I don't know squat about electricity. I was measuring the outlet, a 120v outlet, and not the draw. Gonna try again tonight.

Falling into the depths of obsessive compulsiveness

Just purchased a device called a Kill A Watt EZ. It's an electricity usage monitor. I plan on using it to see how much draw items in my house use. I'm wondering how much power my electric scooter draws, and how much power a turned off thing uses (TV, stereo, appliances, etc).

When I shopped for home solar, installers were surprised how little my bill was. At the time, two years ago, solar would have taken 15-20 years to pay for itself, even with rebates. I'll wait for it to fall under 10 years before I commit to it.

Tying the two together, the Kill A Watt EZ telling me how much juice my electric scooter is pulling may help me figure out about using solar to recharge it. Saw a 45 Watt system from Harbour Freight for $200. Also interested in seeing how much I need to do to recharge a netbook.

I expect this to be fun and interesting.
