Window Socket: A portable solar charger

The Window Socket offers a neat way to harness solar energy and use it as a plug socket.

I would be very surprised it that thing gave out more than a few milliamps.
Single digits that is.

Re: Window Socket: A portable solar charger
 

It does have an integrated battery. So direct use is not recommended i think.

Re: Window Socket: A portable solar charger
 

And just how large is that battery, I wonder?
I too have looked through the page but nowhere did it mention any specs.

lol quite a joke. 1000mAh is smaller than N9 battery, so it cant even provide 5V usb charging for long :)

Its a bit late for aprils fools.

Re: Window Socket: A portable solar charger
 

Had a couple of solars none provided enough grunt now the one i have at least charges the battery that in turn charges the cellp

Re: Window Socket: A portable solar charger
 

Ah, somehow I saw the 5-8 hours but missed the 1000mAh.

Still, I call it a BS. You can't escape geometry. The Sun bathes the Earth with about a kilowatt of energy per square metre. That thingy looks like it might be about 5cm across, giving us about 0.002 square metres to work with. At 100% efficiency this would give us 2 watts. Sadly, the most efficient solar cells available nowadays only achieve something between 15 and 20%. Let's be generous and assume 20%. That will get us to 400 milliwats. At full sunlight.

The battery in my N900 has a capacity of about 4500mWh (3.7V multiplied by 1210mAh - a to power status measurement). Assuming constant feed of 400mW we have so generously allowed above, it would take 11.25 hours of full sunlight to charge my phone.

... Not to mention for some :eek: reasons, it insist on supplying 220V (or 110V, no idea, but mains voltage level), so you loose another load of power on conversion. It's a joke. I don't expect it to be able to charge standard battery N900 in less than 24 hours of *constant*, high sunlight.

It was probably not designed for cellphones, it would most likely be good for some green people who wants to run led-lights at night.
