As the battery level, temperature and charging condition change, the power your phone needs changes too. A fixed charging voltage may create unnecessary conversion loss and extra heat during certain stages of charging.
The Mietubl AVS dynamic phone charger is designed to respond differently.
With AVS dynamic voltage adjustment, the charger can adjust its output voltage within the supported charging range to better match the device's real-time charging requirements.
When your phone's battery is running low, a 20-minute charge can make a meaningful difference.
The AVS dynamic phone charger is compatible iPhone 17 and iPhone 18 models can reach up to 50% charge in approximately 20 minutes when used with the appropriate charging setup.
* Note: Charging performance is based on laboratory testing. Actual charging time may vary depending on device model, battery level, battery condition, temperature, background activity and other factors.
During fast charging, the phone does not require exactly the same voltage from 0% to 100%. The charging system continuously changes according to battery condition and power demand.
AVS allows the charger to provide more finely adjusted output voltage to compatible devices instead of relying only on larger fixed voltage steps.
Less unnecessary voltage conversion. Less wasted energy as heat. A more refined fast-charging process.
Newer smartphones are becoming more active in deciding how they want to be charged.
The Mietubl AVS charger is designed to work with the dynamic charging characteristics of compatible iPhone 17 and iPhone 18 devices, allowing charging voltage and power to adapt as demand changes.
Instead of treating the entire charging session as one fixed process, power delivery can respond to different charging stages.
Compact enough for everyday use. Powerful enough for more than a phone.
With up to 60W output, the charger can support a wide range of compatible USB-C devices, including smartphones, tablets and selected laptops.
For phone charging, the benefit is not simply the maximum wattage. It is having enough power available when the device requests it — while AVS helps provide a more appropriate working voltage when supported.
