Package included: 1 x DC 8V/40V to13. 8V 25A Converter Questions: How to choose the correct current for loads. For example, if the max current of your load device is 10A, then choose 10A/0. 812. 5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0. 520A according to real testing result since the motor and compressor starting current may be 2 3 times than nominal current.
