I have a 10-year old iPod that still works like a champ! I use it on flights and drives to catch up on podcasts, and maybe play a little solitaire. I have other electronics, but music/camera/games have all been software disabled (work’s security restrictions).
I noticed this week, that when I plug my iPod into the computer, it charges fine. When I plug it into the USB port in my new truck, it charges fine. However, when I plug it into a multi-port USB charger or a spare charging battery, it won’t charge.
Has anyone discovered why an iPod will charge in some ports, and not others?

The iPod needs the data ± pins biased in a specific way for it to charge. Most modern USB chargers are correctly biased, but maybe not the ones that are giving you trouble.
