The 300W demo used a Redmi Note 12 Pro+ with a 4,100mAh battery, which is somewhat less than the 4,300mAh battery included in the 210W Redmi Note 12 Discovery Edition (and the Realme has a far more generous 4,600mAh). As shown in the video, the phone reached 20 percent in just over a minute, 50 percent in 2 minutes and 12 seconds, and 100 percent in just under 5 minutes. The charger had a peak input of somewhat more than 290W, and it also managed to maintain 280W and above for around two minutes at one time.
