I use dc converters, you have to remove the integrated one. The first has 19v input that comes from the eliminator and 12v output. the converter you connect the 19v input and adjust it to its 12v output there are some cheaper ones that are only downhill cost 20 pesos, or the one that I leave on the link that can work both up and down. It costs 52 pesos. https://articulo.mercadolibre.com .mx / MLM-619190033-dc-converter-auto-regulation-up-down-24vcd-15a-_JM? quantity = 1
