Is Car charger of 5V, 1.2A compatible for cell phone which need 5V, 850mA?
My original wall charger (of cell phone) output is 5V, 850mA, but output of my car charger is 5V, 1.2A. Will that car charger be suitable for my cell phone? Thank you.
Yes the charger has the capability of providing upto 1.2A but your circuit draws the amount of current it needs (850ma<1.2A). You might of had problems the other way around but in this case your good.
