I am planning to build a device that has batteries and will recharge my laptop. My laptop recharger says output voltage is 19.5 volts and output current is 3.34 maps. What if I don't use 19.5 volts, instead I use a voltage close to 19.5 volts and i don't use 3.34 amps, instead I use a current close to 3.34 amps. I use say 20 volts and 4 amps, will that recharge my laptop?
