Some folks here in the forum and in the FB groups have posted about occasional charging challenges between power stations and power banks with bidirectional charging. I picked up a high speed, high watt USB C to USB C adapter online to see if it would help force the charging direction from the Trail to the RAPID. After a short pause, it worked on the first plug in! I’ll keep testing it out to confirm it fully works, but I’m sharing now in case someone else was thinking of trying this option.
