Q: What is this used for?
A: If you want to connect two RA-2
FCLA adapters together for example, you would use this cable. Each RA-2
could then have a USB adapter (RA-14
) to charge a cell phone. You could also charge two batteries at the same time with RA-8
cables. Many possibilities. Just be sure your solar charger has enough output. A 20 watt charger (F16-1200
) should be adequate to charge two cell phones simultaneously.
