Yes, Igor that is when you bring out the hampster, a tread mill and a 6  pack of brew.

 My experience shows that bigger solar panel is safer. My 60W panel in real life gives less then 1 A on a cloudy day and about 4 A on a bright sunny day when the sun is in its zenith. It also has USB and 12V output which can be used for telephone or iPad charging. Unfortunately rainy days here are more often then sunny :(

  I use a Mercury 27 W foldable from Instapark.com with a 9.9 AH Life04 and runs the KX3 all day and most of the night plus it has a USB port to charge the laptop.

 I am using 60W foldable solar panel, Genasun MPPT controller 
 https://genasun.com/products-store/mppt-solar-charge-controllers/ (they 
 are RF quiet) and 5500 AH LiFePo4 battery with built it limiting 
 circuitry  which some outlets are selling as a substitute for lead acid 
 motorcycle batteries. All works just great with KX3. When using K3 I add 
 one more solar panel and 25 AH LiFePo4 battery. This proved to be enough 
 to keep going the whole day.
