It's not what they claim or not, there is simply NO WAY for a solar panel that size to charge the phone at a decent rate. Plus it is dangerous to leave a li-ion battery under the sun.
Think about it:
Solar panel output
- DC to DC step up conversion loss
- DC to DC step down conversion loss
- iPhone standby energy consumption
-----------------------------------------
= final charge rate.
I have a solar powered emergency radio that barely works with sunlight, and it uses so little power that a pair of AA could last for days.
They are WRONG by saying that in ambient light the solar panel would produce the same amount of energy than under direct sunlight. Why do you think we have solar power plants deep in the middle of the desert?
Please save your money on this
