Great solar cell smears

This is my second solar cell of this magnitude for charging mobile phones, tablets etc.
But it is a fallacy to believe that you upload directly phones etc with these solar cell
can! I did this several times tried the result was a discharge of the connected device!
If you want to use this solar cell in the sun to charge, so you need a Power Battery
which is connected to the solar cell, and by this battery can then load the connected devices!
So to speak, a buffer battery switch in between. Property me this a 13000 mAh USB Power Battery at Amazon
bought, and it works perfectly! Simply looking at Amazon for anchor USB Power Battery, and then select the output.
For a 7 watt solar cell, a 13000 mAh battery is recommended, as the charging current in full sunlight about 1.2 amperes
is, and the battery is then charged within 14 hours. In cloudy sky it will then already by 100 hours So do not expect too much! Works for me but well in sun, battery is full quite quickly.
