Interesting info! You can also use an ammeter or something like the Kaisi battery activator ($20 unit with some other benefits for repair techs) to determine if the Amp draw through the lightning port is within normal range. I'm a bit hesitant personally of unplugging the battery while sending a charge through the lightning port. It maybe safe, but it seems like there is potential to cause issues due to how touchy the Tristar is to voltage irregularities in the first place.
