I want to be sure I understand you correctly, because I'm not too confident in this subject. You're stating that if my device is designed to run on lower than 2.4A, but I charge it using a 2.4A charger, it'll frequently charge and stop charging, then charge again? Does this mean also that I want to be careful to not use a beefy charger for my phone, rather than thinking "bigger is better"?

No, I don't think that is what was being communicated.

Basically, your device is designed to charge at a specific rate and it will draw only up to a specific amount of current (amps). Having a device that is capable of delivering more current doesn't mean your device will draw that current. A cell phone for example will have a varying charge rate, something that generally is between .5 amps and 1amp, with some devices capable of drawing 2 amps. But if you plug your phone into a 5 amp charger when the phones maximum rate of charge is 1amp, it will only draw 1 amp.

So in the end, bigger does not equal better, except to say that your highest charge rate should be equal to or less than the charging device, which helps keep heat to a minimum.

Correct.
