For in-car charging, why would one choose to use the 250SE over the Smartpass120S?
Apart from the additional solar input in the 250SE, the 250SE can only charge at up to 20A, whereas the 120S can charge at 120A. Is solar the only reason, as the 120S has 5-fold the charging rate.
When combined the 250SE + 120S can charge at upto 140A with 20A solar input. Why then would someone use say the RedArc 1250D which can only charge at 50A. Is the ability to charge at 50A via solar in the RedArc the main reason?
All these options are doing my head in!
