What is the model of the charger that comes in the box? (UK)

Just buy any reputable Qualcomm Quick Charge 2 or 3 charger, as good or better than OEM. There is no benefit to having a Motorola branded one.
[FONT=&quot]I ask because I've tried the [/FONT]5V/0.4A[FONT=&quot] plug that came with my [/FONT]Linx 12X64[FONT=&quot] tablet and the [/FONT]Samsung Adaptive Fast Charging travel adapter[FONT=&quot] (9V/1.67A or 5V/2A) that came with my Samsung Galaxy S8+ and both appear to trickle-charge the Moto G (2015).[/FONT]
 
My wife's Moto G3 (2015) did not come with a charger. And this phone definitely does not have quick charge!
