I saw this posted on Facebook, and I'll make the same comments here...

It's fake - or a highly doctored 'someday'.

1) Solar panels that small won't put out much DC voltage or current.

2) Since there is a European 220VAC plug inserted into the socket, this means that the low voltage DC is having to be boosted to 220VAC - and also converted to AC. Lots of losses there.

3) Since there is also the 'storage' of current - this means or indicates an internal battery (or supercap). With the mockup shown, they're running out of room fast.

It's great to 'blue-sky' - sorta like making a photoshopped photo of a flying car - but it is not real.

If it were possible to do this, it would be a small step away from really practical electric automobiles with small battery packs, and rechargeable from the sun. We don't have those, either.

For people that want to 'Plug in' a calculator or a novelty bulb, or a fan with the breeze of a farting gnat....

That is fake.

The device shown had a diameter of about 4 inches. For the sake of argument, let's pretend that that 4 inches are ALL solar cell. The area of a 4 inch circle is 12.5664 sq ins., which is 8.75% of one square foot.

The estimated maximum energy delivered to the surface of the earth by the sun is 600 watts per square meter. One square meter equals 10.764 square feet, so one square foot would receive 55.741 watts, and therefore this device would receive a maximum of 4.87 watts of energy per day. The best commercially available photovoltaic panels can achieve an effiiency of 21%. So under THE BEST conditions with THE BEST materials, this little window sticker could output 1.0227 watts per day.

Such a device would be nearly useless and is probably a scam aimed at the innumerate.

oh gosh. I wanted one. Well,thanks to all you folks who know something about the subject. I won't run out and try to buy one!

They only need to sell one per customer. Repeat customers not needed with the mark up of this gag. Hit and run.
