The OnePlus 5T Dash Charge feature is one of the best fast-charging options out there, pumping the Snapdragon 835-equipped phone full of electrons at lightning fast speeds. It couldn't be otherwise, as the OnePlus, Oppo and Vivo brands are members of the same parent company, BBK, and we all know how fast Oppo's VOOC charging system is, thanks to its 20W output, same as the Dash Charge, in fact.
That is why OnePlus is so adamant on advertising how quickly you can top up the 5T in any creative way imaginable. First, it was direct comparison with the competition, and now it is something funnier to watch, yet no less informative about the Dash Charge capabilities. To spare you the suspense, the phone finished first in less than an hour, though a small disclaimer at the bottom says that it was off at the time of charging. It's oodles of fun nonetheless.
