EnergyStar plugpacks

Sep 18, 2007 103 Replies

I just got a new Nokia mobile phone and it came with a switchmode mains charger plugpack as many of them do these days, but this one has an Energy Star label saying this adapter was energy star compliant for reduced consumption. This is the first time I've seen this on any plugpack, so I thought I'd test it out.



I got 0.12W on my energy meter with no phone connected. Compare that with 0.55W for my old Nokia transformer plugpack, and 0.55W for a (presumably non-energy star compliant) Motorola switchmode plugpack.



That's a big saving, especially when you multiply it by a few tens of millions of phones. Very nice indeed.

My charger sits in the drawer until I need it. That's 0.00W when no phone is connected. Furthermore, my phone doesn't have any unnecessary energy wasting features such as cameras and the like.

Much easier to simply switch the power point off, but then of course the wife complains that it "looks messy" :->

My new phone has more standby and talk battery life than my old phone monochrome Nokia, and it's got a 2MP camera, MP3 player and all the frills, and a ridiculously bright 2" screen. Amazing. But it's got like 3 different power saving and power down modes, haven't figured them all out yet, might have to RTFM to save some time!

Try finding a phone these days without a camera ;). Last time I looked at the local Telstra shop, (over a year ago) even the cheapest models all had cameras.

Will have to face up to this in the new year, as my current CDMA will be useless, and will be forced to upgrade to a next G phone with all these fancy features. from what I hear, as a bonus, the coverage will be sub-standard outside major cities, but hey, look on the bright side, in addition to the cameras, MP3 Players, FM radio, etc etc we will also have fancy "must have" features like pay TV and "mobile internet at broadband speed " that I, and most people would never use, and wouldn't pay typically excessive access fees for. What happened to the people (surely a significant number) who just want a phone that they can use reliably ?

I'll be keeping my old anti-ROHS lead based solidly constructed phone for canyoning and other adventure stuff. I think it will survive being thrown down 10m waterfalls much better than the new one.

Dave, you drank the Fresh-Ade about mobile phone chargers eating power.

People in the developed world use something between 120 kWH/day (Europe) and 300 kWH/day (Canada or the US). If every one of them saved 0.43W continuously, 24/7, that would be an improvement of 12 WH/120 kWH or

0.01%. And that's if _everyone_ had a mobile, and _everyone_ got a new charger. Not to mention the energy cost of manufacturing all those new chargers.

Every little bit doesn't help.

I see your point about it making bugger all difference, and agree (there are much more effective ways for everyday people to save much more power) but I find it very hard to believe that every person (or household) - even in the US (home of all extravagance) could use

120-300 kwh per day. This alone would equate to $18 - $45 a day (at 15c per kwh) which I doubt is possible to sustain, or maybe this sort of financial drain is contributing to the US sub-prime meltdown ? ;)

That figure isn't just electricity, but includes gasoline (the biggest use for most of us), home heat, the inefficiency of electric plants, and the energy required to make and transport the stuff we use. I got the figure from David MacKay's (draft) book, "Sustainable energy--without the hot air",

It'll be a pretty good book when it's done, and it has some excellent sections even at this stage.

This online book is quite interesting - it tries to put things like your charger into perspective.

No I didn't. I just found it interesting from an engineering point of view that you can now get these low standby power adapters. Even if it saves a small sniff of power, I just though it was elegant from an engineering point of view, a NICE thing to do.

I know. I wasn't implying that it would help save the world or anything, and I'm not saying everyone should rush out and buy one because it's going to save them power, but it's certainly not a BAD step forward for the industry. You can fiddle with numbers and their relevance in the global scheme of things all you like, but 0.1W will always be better than 0.5W.

*sigh*

** So the cretin is still unaware we are being FORCED to use such adaptors for all applications - whether they are safe or suitable or not.
** What the " industry" making AC power adaptors is being FORCED to do IS a bad thing.

The ban on the sale of iron transformer adaptors begins in April next year.

Of course I am aware of that Phil. My posts have had nothing to do with that at all.

Of course *that* is a bad thing, but my posts had nothing to do with that at all.
