The difference is the charging current of 5.0A compared to 0.8A. If you only want to charge your motorbike battery or a car battery from time to time, you can go for the 0.8 model (suitable for a battery capacity of up to 32Ah). For more flexibility and other applications, especially for larger batteries, we recommend the 5.0 model (suitable for a battery capacity of up to 110Ah).
