I would not deny. During charging it heats but if you do not use it while charging then it is Not at All a issue, I suggest that do not use your device while charging because this device charges up very very quickly, be a little patient to increase your device’s life by many times. -Turbo Charger You would not get it on Xiaomi, Moto’s Turbo charger is very very good. Solid Build Quality, Long cable, Very Fast Charging.Never Worry About Charging -Battery Very good battery life.
