Kill-a-Watt meter

[Brammofan]

I wasn't sure whether to put this in servicing or mods... it's just a useful tool to find out exactly how much juice you're putting in your Enertia.  Implovator uses it to figure out his energy use, and I've heard of other users doing the same. 
P3 International P4400 Kill A Watt Electricity Usage Monitor

Definitely an affordable way of monitoring your cost per mile, savings per mile, and other information for the anally-retentive among us.

Any word on what his kill-a-watt meter reads when charging and or in float mode? I have that meter as well, and find it invaluable

All the best,

I have a Watts Up, which is very similar in concept. I agree that a meter like this is invaluable to an e-bike owner.

My boss used the same thing on my bike just to make sure I'm not sucking the life out of his company, the first day while the bike was parked out in the sun it read 58 cents after getting fully charged from around 35% while the next day we charged it indoors at about the same percentage drain it read 48 cents, my boss couldnt believe how cheap it really is to charge the enertia

[Brammofan]

The Kill-a-watt is an invaluable tool in getting your spouse to believe that the reason the electric bill is so high is because the AC is running all the time, and it is not the bike.  In KC, it costs me about 25 cents to charge it from 20%.

Wow if only electricity was that cheap here I would be cranking up the AC all day long too lol

[HighlanderMWC]

I'm running about $1.20 for the days when I'm charging from battery levels of 8-15%, but that's due to $.39/kWh

[werm_works]

Whoa were do you live???

[HighlanderMWC]

San Francisco. It's a tiered rate system and .39 is the highest tier that my family is usually in.

[Brammofan]

  Wow... that almost 4 times what I pay.  My sympathies to you.

Just ordered one on Amazon...

just for kicks...and yes my wife questions how much it draws from time to time...and we have AC and a swimming pool...so my bike is a minimal draw compared to those two.

My wife asked me the same thing because our bill went up about $25 a month shortly after I got the bike.  I tracked it down to a new TV set that we got at about the same time. It seemed to draw ALL the time, whether off or on.

I have been using one of those meters to follow the charging process of my 2012 Zero. When bulk charging the meter reads around 900 watts, plus or minus 50 watts. After bulk charging is completed, it cuts off quickly (instead of tapering the charge) and goes into a 7 watt trickle-charge mode - where it stays until the cows come home.

I've been metering my power consumption so far - I'm typically using between 120-130 Wh/mile, so I've added about 32 kWh to my utility bill so far this month. I anticipate total monthly bills in general will go up by around 100-120 kWh ($8-10).

Historically I use a yearly-average 650 kWh/month, so the ebike will be a noticeable but relatively small increase.

gonna have to learn some math...

energy charge:

First 450kWh------- 0.0906237/kWh
Next 450kWh------- 0.1373455/kWh
All Additional kWh--- 0.1576960/kWh

Of course with the solar panels we are usually in the plus range...though in June, July and August we will be in the first 450 (maybe even into the next 450 if we are using both the Air and Pool a lot....but we also produce a lot then too, so we still usually break even)...

What do those rates come out to with an Enertia?  A Plus?
