Package includes: 1 x DC 8V/40V to 12V 25A Converter Questions: How to choose the right current for loads. For example, if the maximum current of your charging device is 10A, please choose 10A/0. 8=12. 5A at least for resistive loads according to international standard. If the charging device is motor or compressor, then you can choose 10A/0. 5=20A according to the actual test result, since the starting current of the motor and compressor can be 23 times than the rated current.
