Variable vs Fixed Voltage?


Variable Voltage sockets use built-in smart charging technology to communicate with the individual device, to only deliver the power a device needs, when it needs it. Meaning devices can charge from 0-50% or more, in as little as 30 minutes.


Variable Voltage follows three stages of charging: Stage 1: Where fast charging occurs – 50% in 30 minutes. Stage 2: The output slows as the battery nears full to protect battery health.


Stage 3: Once the battery is fully charged a small charge will be offered periodically as a ‘top up’, whilst pushing the maximum output to the other USB Port.


This protects and prolongs battery life, by never overcharging connected devices. Variable Voltage USB Sockets are available in 45W & 22W.


Fixed Voltage sockets offer a cost-effective solution where speed of charging is not a priority (e.g. charging overnight). These sockets will enter standby mode when a device is fully charged, protecting the devices battery life.


Fixed Voltage USB Sockets are available in 15W & 12W.


Is 45W Faster than 22W?


A 45W wall socket typically charges faster than a 22W wall socket, however charging speeds will vary depending on the device and charging conditions.


Device capability: If the device supports fast charging of 45W or above, you will see faster charging than with a 22W socket. If the device can only accept 22W, then the charging speed will be the same. Cable quality and type: The charging cable must support higher wattage for fast charging.


Battery management software: As the battery gets closer to full capacity, the device's software controls may slow down the charging speed to prevent damage, affecting the perceived charging speed between a 45W and a 22W charger.


45W wall sockets are perfect for charging higher powered devices such as laptops & tablets. 22W wall sockets are ideal for smartphones and smaller devices.
