"What I am wondering is what the input carbon for a solar charger would be and from that it is a very easy calculation to work out if it makes any sense..."

"Oh... I see... you mean the time it would take to offset the carbon cost of it's manufacture?

Sorry, I totally misread your first post...

Wouldn't you need an estimate from the manufacturer for that?"

"Here's one answer...
