Current Surge Safety

R

High current, especially a sudden surge of current due to eg. component failure is usually a precursor to dangers. Prüfen’s microprocessor continuously monitors current flow from Power to Recipient Device. If current flow is abnormal, Prüfen AUTOMATICALLY ABORTS charging and displays an current error message.

R

Using USB Power Adaptors from dubious manufacturers with over-rated specifications are hazardous. Mobiles and Tablets that have been subjected to high impact are also at risk. It is important to monitor the currents of these devices during charging.

R

Charging is aborted when Charging Current goes above 2.4A for both 5V and 9V
