What is a charger?Ī charger is essentially a converter with a sophisticated multi-stage charging algorithm. This flat voltage is just enough to sustain your 12V batteries and the DC devices that run off them, but this can be a recipe for shortened battery life. For example, 12V converters typically output a flat 13.5VDC. A standard converter outputs a single voltage, up to its specified amperage rating. These 12VDC devices are advantageous because there is less of a power draw compared to their 120VAC counterparts. We need this DC voltage to power various 12VDC devices such as lighting, fans, refrigerators, etc. In most RV, marine, and off-grid applications we are going from 120VAC to 12VDC. Simply stated, a converter takes AC voltage and converts it to DC voltage.
In some cases more than one option will work for you, while in others there is a clear choice. I am going to go over the differences and similarities between them. Are you having trouble understanding the differences between converters, battery chargers, and converter/chargers? Well, you are not alone.
