[Elecraft] KX3 Solar backpacking power advice

[Ignacy]

Probably the weight is a concern. 

You may use a foldable panel (e.g., 5W) and either charge internal
rechargables or external Lithium.I was frustrated with foldable panels
because of low output under less than perfect sun and poor reliability. 

The other option is to take enough Li-Ion batteries.  I prefer Li-ion
instead of LiFe-PO3 because of lower weight.   A 11.1V (12.6V peak) 5A
battery weights 300g (10oz) and should last a few days. Note that KX3 uses
almost half current at 5W if supplied with > 11V.
