Smartphone manufacturers have increased their focus on creating fast-charging technologies in recent years. Even Apple utilized such a technology last year when it introduced the iPhone X, iPhone 8 Plus and the iPhone 8. This doesn’t just help companies attract customers during marketing campaigns, but such customers are able to top up their phone’s battery capacities in a very short period of time.

Right now, OPPO is the leader when it comes to fast charging technology thanks to its Super VOOC tech. This fast-charging progress was most recently seen on the Lamborghini Edition of the Find X flagship. It can fully top up a 3400mAh battery in just 35 minutes, making it a very attractive selling point for customers who want to get a couple more hours while plugging the phone in the power brick for a short period of time.
