Review on 🔌 UNU Quick Charge 3.0 Car Charger: Dual USB 36W Power Charger for Samsung Galaxy, iPhone Xs Max, Xs, Xr and More Devices by Eric Grayson

Okay, that's a homework example. I haven't spent more on fast chargers because I know the phone will end up using only as much current as it needs to charge the battery, given the five volts it has to handle. Ohm's basic law, that's right, power, voltage, current - it's all related. Okay, this time I did some research and found that the fast charge function actually matches the voltage to allow the phone to charge faster and let me tell you it absolutely is faster. than any standard high power charger. What to do with other car chargers now? Also, the other port provides enough power to charge my iPad mini.
