• Most odd. I have three Anker. I've used one of them a shitload. All my races, most training rides over say 7hrs and no issues with it or the other two (one smaller lipstick, one big double usb one).

    How are you charging them? Tried plugging into a PC?

  • Better regulated currvolties™ I guess. I've heard people charging Di2 with power packs have thought batteries are dead only to plug them in using a PC and it works again.
