This is good info and describes my charging situation, thanks for the info. I wish I had researched this more before but moving forward with a better solution won’t be that big of a deal.The EC Off-road USBs are at best going to probably only work at 2.5w (500ma@5v). Modern phones need a lot more power than that, or at least you are going to want more power for any decent charge rate. You really want a modern USB output that can do PD (usb-c) and/or a USB A port that will do negotiation to higher voltages. Most phones will work with these now.
These can charge phones usually at 10-30w. New iPhones/iPads use PD, so that’s the way I would go. A USB A with QC would cover all your other possible needs.
I’ll shop accordingly.
