Our smart-charging device helps keep the Lithium-Ion battery of all your devices healthy.

Leo's algorithm automatically implements all the best-practices for battery lifespan optimization and charges with a focus on reducing battery degradation.

Healthy battery
Prevents the battery from spending hours in a fully charged state (automatically stopping the charging at the right time)
Zero waste
Avoids high battery temperatures, by adjusting charging speed and taking breaks
Plug and play
Charges at different speeds to reduce unnecessary fast-charging, for example during the night

Besides these functions, with Leo you can:

Healthy battery
Measure and analyze data such as the current and voltage at the charger level, and the charging protocol. Leo can function as a USB multimeter!
Zero waste
Charge, measure and save the battery for all your USB-C devices. Use it for your smartphone, e-reader, headphones, speakers, tablet or even your PS5 controller
Plug and play
Perform Over-the-Air firmware updates using our App, as we continue to improve our algorithms using AI

Stop planned e-waste!
