United Kingdom, Sept. 15 -- Apple has introduced the 40W Dynamic Power Adapter with 60W Max for its new iPhone 17 series.

The new fast charger, priced at $39, supports the USB PD 3.2 AVS (Adjustable Voltage Supply) protocol, allowing the adapter to deliver more precise voltage tailored to charge cycles.

Although it's marketed as a 40W charger, the adapter can reportedly reach up to 60W output for a time - but only for around 18 minutes - before it scales back to avoid overheating.

Apple claims the brick can fast charge the iPhone 17 models to 50 per cent in about 20 minutes, up from the previous 50 per cent in 30 minutes on older iPhones using the 30W adapter.

Alongside the charger, the iPhone 17 lineup brings several notable upgrades...
