Dreame Pocket Aura AI High Speed Hair Dryer

How fast the motor spins, in revolutions per minute (RPM). A faster motor moves more air from a smaller, lighter dryer.

110,000 RPM is about 1,800 turns every second.

How fast air leaves the nozzle, in metres per second (m/s). Faster air pushes water off the hair, so it dries quicker with less heat.

70 m/s is about 250 km/h.

Charged particles the dryer releases as you dry. They're designed to neutralise static on the hair, which helps reduce flyaways and frizz.

Loudness in decibels (dB). Every 10 dB higher sounds about twice as loud.

30 dB is a whisper or quiet bedroom. 40 dB is a library. 50 dB is a quiet office. 60 dB is normal conversation. 70 dB is busy traffic. For a purifier that runs overnight, the lowest figure is the one you'll hear while you sleep.

The mains voltages the dryer works on.

Singapore uses 230V. A 100–240V dryer also works in Japan (100V), the US (120V) and the UK, Europe and Australia (220–240V) with just a plug adapter. You don't need a voltage converter.
