WITTY Power battery protector for cell phones ASO black

Why do our smartphones lose battery power so quickly?
The lithium batteries contained in our devices have a natural life cycle that can be influenced by various factors. One of them is nighttime - or generally long - charging, which takes an average of 8 hours per night and negatively affects the capacity of the lithium-ion cells. Namely, the battery is maintained at its end-of-charge voltage of 4.35V, even when it has reached 100%, to ensure that it does not discharge during the night. As a result, the battery life can even be halved, forcing us to buy a new battery or change the device.

Innovative technology
A team of electronics, mechanical and management engineers at Sapienza University in Rome has developed a technology that can prevent the lithium battery of USB-chargeable portable devices from remaining at their final charge voltage of 4.35 V for longer than necessary their lifespan doubled.

The so-called ASO (Automatic Shut Off) technology allows an increase in device performance so that the user can fully enjoy their devices. With Witty you can revolutionize the (nighttime) charging of your devices and put an end to the stress caused by a weak battery.

How does ASO work?
The ASO (Automatic Shut Off) is able to read the energy required by the smartphone from the charger and, thanks to a switch, disconnect the battery from the mains when the device's energy requirements are met. Unlike all other charge controllers, ASO does not read the voltage or capacity of the battery, but analyzes the current flow between the device being charged and the charger. Disconnecting the battery when fully charged prevents the battery from remaining at the end-of-charge voltage even after reaching 100%, which is extremely damaging to the electrodes of the lithium cells, allowing the battery to be lowered to a more comfortable voltage and its discharge cycle begins . It's like relaxing your muscles after an intense workout.

ASO is a European technology Made in Italy, patented by Witty.

Plug and play
Witty is super easy to use and intelligently manages your device's charging process.

1. Insert between charger and charging cable
2. Press the button
3. Charging is in progress, with ASO

compatibility
Witty is compatible with all portable devices that charge via USB Type-A, such as smartphones, tablets, smartwatches, headphones, Bluetooth speakers or digital SLR cameras. It is compatible with power supplies up to 65W, but charging is limited to the USB standard of 4A. There is no operating system limitation as it can be used with both iOS and Android. NOTE: The product is compatible with iPhone 13, Samsung S21/S22, OnePlus 9 Pro, etc. (sold from version 11/12/21).

ATTENTION: Witty only charges one device at a time. If you use a wireless base that can charge multiple devices, Witty cannot detect when the device is charged.
ATTENTION: Witty may not be compatible with wireless charging stations equipped with an LED.
ATTENTION: Witty is not compatible with laptops, notebooks and ultrabooks.

Environmentally friendly
By using batteries more efficiently, Witty reduces the amount of battery waste and slows down lithium extraction, which causes major water waste and CO2 emissions.
