Someone new to FPV and cannot find any information that tells me how to charge the TBS Crossfire Transmitter. I tried connecting the USB cable to my computer and left it connected for several hours, but I don't believe that charged it at all (or perhaps extremely slowly). I see the TBS Crossfire Transmitter came with a XT30 to JST cable. Is this what I'm supposed to use to charge it? Buy this connector (https://hobbyking.com/en_us/xt60-jst...E&gclsrc=aw.ds) and hook it up to one of my 4S drone batteries? Or can I charge the TBS Crossfire Transmitter through my Taranis X9D plus radio?

I looked over the TBS Crossfire manual but I don't think it covers how to charge it; very surprising and a bit frustrating for someone new like me.

Any help /pointers are appreciated!
