What if we all changed our chargers?
By Charlie on 29 April 2008
Ok. So I am a bit loony, but I’ve been excited for a long time by the Nokia High Efficiency Charger. From what I’ve been told, normal Nokia chargers draw about 150mA power when just plugged in and not charging a device (when the charger is on standby). The High Efficiency Charger only draws 15mA when plugged in and idle (I might have to be corrected here, but I do know it’s a 1:10 ratio).
Why is this important? There are over 3 billion phones out there. And I am sure there are more than 3 billion chargers. That’s a lot of power being consumed just to leave the charger plugged in. This wasted standby power is called sometimes Vampire Power.
I thought our High Efficiency Charger had no load during standby. Sure, it’s still a really efficient charger, but I wished we could do better.
Well, I hear that there are some folks in Nokia Design working on chargers that produce no Vampire Power.
James reports from the recent Nokia Design Event that:
This is exciting. Lots of chargers. Lots of Vampire Power. The world waking up to the problem. Now Nokia doing something about it, too.
As for what we should do while we all wait for these chargers to start showing up: 1) unplug chargers when you’re not using them, 2) get newer chargers that are Energy Star compliant (which I would expect most major brand chargers to be, these days), 3) demand zero standby energy from all your favorite electronics companies.
What do you think of Vampire Energy? What are you doing about it? Or do you think it’s just a drop in the bucket?

This is very useful information. Each one of us can make a difference by simply unplugging our chargers!We should communicate this message widely.

Makes sense to me; I tend to be one of those that will leave his devices plugged in all night. Might have to start setting an alarm to beep me when its done charging in an hr or two until I can get one of those new fangled chargers.

I guess that goes for the most of us that leave the charger in the outlet, including me. There are a couple of things:
- Handset manufacturers don’t only make phones, they make accessories including bluetooth headsets and other power-dependent accessories. I’d estimate that 3 billion figure for chargers mentioned is a minimum figure for these out there.
- I have many Nokia devices that need power, but I usually try to leave not more than one charger in the wall. This is key for people who have devices that use the same charger.
