Hi de hi happy campers :) just got a galaxy s7 and found out you can have a fast charger that uses 9v now i have searched google and youtube for fast charger etc etc and got loads of useless videos of how these chargers work sooo, if someone can enlighten me how they work please... are they a 9v psu and the phone is happy with it but a none supported phone will fry? are these chargers output normally 5v with a communication line to make the dc-dc converter push more voltage so any other 5v device will be safe unless it communicates? inevitably my idea is if i can is make one into my battery bank box for high speed charging, currently im using a 4s10p 18650's going to a 5a buck converter which sits at 5.2v feeding usb sockets and the center data pins are shorted for 1amp charging on normal phones many thanks for your ideas and help |

Almost all of chargers use data lines to regulate charge current. Simple chargers use voltage dividers or shorted data lines to tell phone how much current they can deliver. Quick charge phones use similar method, with one exception: voltage on data lines is set not by a charger (voltage dividers) but by phone. That way if you connect a normal phone to a quick charge charger nothing bad will happen, because phone will not request higher voltage. Some quick charge technologies even use data lines for more complex communication with a charger. You can read more on this subject on this site. |

you want to look for a QC2.0 or 3.0 charger, that is what the samsung phones are compatable with for quickcharge the phone tells the charger what it wants. and the charger responds. |
