The smartphone pictured, made by Realme, has set a world record for charging speed — 26% in one minute of charging and a full charge in just 4 minutes and 15 seconds.
This charging rate was achieved using 320W charging.
For comparison — your smartphone's fast charger is most likely 15–20W.

Ultra-fast charging exists primarily in devices from Chinese manufacturers.
The reason you won't find it in devices from reputable companies like Samsung or Apple is that fast charging comes at the cost of significantly accelerated battery and device wear.
The extremely high current generates a great deal of heat, which both degrades the battery and damages the delicate electronic components inside the device.
Western brands are largely considered high-quality based on how long their devices last over the years, which is why they prefer to cap charging speeds.
For the same reason, charging electric vehicles at fast-charging stations is not recommended, as it harms battery health.
And a final tip — if you own an iPad Pro, you can charge it with a 30W charger, significantly reducing charging time compared to the 20W charger included in the box.
But of course — keep in mind the impact on your iPad's long-term health.
