• A brief follow-up - my Bangle.js 2 seems to charge at around 98 mA for the majority of time, then by the time it reaches "100%", it has tapered off to 67 mA, where my powerbank then cuts off power. This is before Charge Gently (chargent) even activates. My USB power meter was powered separately for the tests, so it did not impact the powerbank cutoff.

    Taking it off the charger, letting the voltage settle, that put my Bangle 2 at around "96%" (and a few hours later, "94%").

    This is an excellent solution that turns an aggravation with my powerbank's cut-off into a free hardware charge limiter for my watch, thank you @halemmerich for the idea!
