Depends on how you define vampire. If you mean completely parasitic and useless, that's one thing, but if the load is actually doing something, that's something else. Yes, I do have 20+ tiny loads that I can count off the top of my head, but most are on the order of 1W each (cordless phone charging dock with a phone in it), or they're actually doing something semi-interesting (eg. hardwired smoke alarms, clock, router, dvr hunting for shows to record). True vampires (eg. phone chargers not on a power strip, idle PC speakers and or/their wall warts, shredder, etc)? Nope. Although I welcome suggestions for something I might have missed.

See, my problem is that if the Blink does in fact draw 21kwh a month, that's literally 10% of my ENTIRE monthly electrical usage pre-LEAF - so I feel somewhat justified in (anticipating) not liking it and saying so, especially if there's no technical reason why it should be that way. I realize my total usage is crazy-low, and if that load was 1% of my total like it would be for my next door neighbor, I suppose it wouldn't matter.

When I mentioned to an Ecotality guy at the SD rollout that there were statements floating around that the Blink drew 30w when idle, he emphatically expressed that he thought that would not possibly the case (realizing that it would be irritatingly high), and that it "should" only draw "a few milliamps"...eg. 25mA @240V would be 6 watts. But he didn't really know, and the claim of 30w supposedly came right from the manufacturer. So I'm thinking it could well be true. If it draws 6w, then you're right, it's not worth losing sleep over and there are any number of other similar loads to worry (or not) about.

Possibly, yes. Or "trade" it for the clipper creek which has a much more reasonable 4-5W vampire draw (still too high though, IMO!)

No kidding.. my "nighttime, nobody home" power floor is over 500W, what with all the WiFi, chargers, computers, remote-control stuff.

My house is a whole clan of vampires.

Ouch - that's 360 kWh/month right there!

maybe there is a way to just turn off the wi fi. or lower its power output when it "knows" the car is not in the area.

30 watts is high and suspect. 5 watts is marginally acceptable. i just took my killawatt meter around to several gadgets in my house and 3-5 seems to be the norm. was a bit shocked to see that on my DVD player when it appears there is nothing but a clock on it when its off.

but i have so much other stuff that is on all the time...netflix instant view, have 2 of them. it does nt even have an on/off switch.

funny though, my wi fi i checked it, it uses between 40-80 watt so not a whole lot difference.

I put a call in today to someone from Ecotality about the Blink's standby load. I left a message. If I ever get a call back, I'll report what they say. Once the Blink unit is installed, my TED will tell me exactly what it's using. More info if/when it becomes available.

Ouch - what kind of wifi device do you have? Mine uses about 5w. An older one I had drew 10w. If you replace yours with a low power one it will pay for itself in a year.

Thanks Jimmy....I'm in the ETEC project, and I will not be happy if the Blink draws 30W just sitting there. :o

Agreed - I just put the power strip which has my Cisco cable modem, Belkin Wifi Router (which has a fairly big, warm wall wart) and Sunpower data gateway all on it on the Kill-a-watt - 12 watts total. Looks like the cable modem is 4-5, router is 5-6, gateway is 1.

When I install wall sockets for 120 or 240v EVSEs, I will also install an appropriately-rated wall switch directly alongside each socket, and one for the (probably unused) hard-wired connection, if any.

It probably (?) will not hurt the EVProject data to have the Blink shut off when it is not being used.
