Fast chargers have been invented to overcome the long time it takes to charge a smartphone. If the battery mAh is more, charging with a normal charger is a matter of time. So, in the case of such batteries, fast chargers are being offered with many smartphones to save time. Oppo K10 5G (China) is one of them.
Oppo K10 5G (China) is one of the phones that came in the market with a huge battery and a fast charger. The phone comes with a 67-watt fast charger which will take only 29 minutes to charge the battery 2-80%. So, it would no longer take the normal amount of time it used to charge a 5000 mAh battery.
