Longer Cable for Solar Panel

Need a longer cable for the solar panel, 13 feet is too short for our application, 20 foot would be much better.

I was on the fence about buying on of these if an extension can be added to the cord, I assume you could just plug another USB cable into it?

Marlin, I’m wondering if you ever attempted adding an extension. The output of that panel may not handle the extra length (and it would be tough to test on the ending connector). The panel’s rated at 2.5 watts at 5 volts DC. I’ve been trying to get other specs on the panel so I can test it but “support” can’t find anyone who can answer a spec question (Voc, Imp, Isc). Let us know.
