Just Browsing Solar charging

[Brant]

I’m sorry if this has been discussed, and I’m sure it has, but I’m new to this. I’m wanting to setup a solar panel to charge my 1 expander 12v battery while in storage. Just a portable one. What amount of Watts do I need in the solar panel? Is 160w enough??
Peoples advice will be very much appreciated.

Also along with this, would a solar Mat be enough to keep the battery charged when away for using to charge phones. iPad and alike?

160w is plenty. If its charged before its stored you easily get away with half that, but theyre cheap enough to stick with the 160w, its more useful

Couple of amps per device, an hour to charge each, max of 4 hours of sun. 20w per device more than enough
