**Can I use the charger that came with the Moto G4 (**Motorola 15W 1 piece Turbocharge™ Wall Charger) to charge my Moto G4 Play?
It shouldn’t be a problem. For what it’s worth, Motorola’s guidance is here: How to properly charge the Moto G Play (4th Gen.)?.
I agree with @rolandh . I recently used the “turbo charger” (or whatever Samsung calls it) that came with my S7 to charge my granddaughter’s Moto X (2nd Gen) and it charged if faster than her native charger.
