Rechargeable NiMH AA batteries with USB

Submitted by on Sunday, 23 March 2008 Loading Add to favourites  5 Comments

rechargeable NiMH AA batteries with USBI have to admit it; despite all my sustainable efforts and rustic lifestyle, I’m a gadget gal at heart.

So, GREEN gadgets from ethical companies, really get my adrenaline going and I just love this offering from my friends at Natural Collection.

Here at Chez Green, we get through heaps of batteries for cameras (yep plural, disgraceful I know), clocks, little Miss Greens very un eco friendly plastic cd player (hangs head in shame) and an mP player (we SHALL have music wherever we go).

Although we religiously use rechargeables, I’ve always thought it a bit strange that I have to take power from the mains to charge up our batteries!

So imagine my happy dance when I discovered this Pack of Two Ingenious Rechargeable NiMH AA Batteries that have a hidden USB socket inside the lid!

Yes, dear readers, as you fritter your life away on the net, write emails, or browse Birkenstocks on eBay you can be charging up your batteries. My trusty laptop only uses 15p a week to run, so this would be an economical way for me to charge up those lovely AA cells and save a little juice from the mains.

Winner of the UK National Energy Efficiency Award for Consumer Product 2007, these get the thumbs up from me.

Have you tried them? Do they deliver the promises they make?

    Hey Mrs G, nice post and thanks for the nod our way :) I myself have 6 of these batteries and have to say I would be loathed to buy regular batteries ever again. Makes it so easy to recharge…

    Namaste

    It’s good to hear of someone actually using a product and giving a recommendation.
    I hope you had a wonderful Easter Day :)

    Only ran into this today so the comment is four years out of date – not sure if you’ll see it?

    Does this really save energy? I would imagine that plugging the battery into the USB port of a computer for recharging will drain extra power from the computer itself – either this means that you will have to recharge the computer’s battery sooner, or, if you are running the computer off the mains you will draw more current from the mains.

    My mobile phone can be recharged via the USB on the computer. Using a plug in monitor to the see the power consumed by the computer, I found that plugging in the phone increased the power consumed by about 3 watts. So it would only be the case that this saves energy if charging the phone by the mains consumes more than this.

    So you know how the sums work out?
