Well i want to use it to power on my laptop directly to a big Lithium battery (100ah/12v)
My laptop electric specs are DC output 19.5volts 11.8amp
So i made the cirquit, i plugged the DC regulator to the battery and the laptop to the regulator ( and set the parameters on the regulator then press OK button)
My issue is that the device gives me the apropiate voltage output (19.5v) but its delivering zero amps
I also tried the auto mode and same thing happens
On the laptop appears that its plugged in but the battery its not charging
1- PC 2 pins fan ( 12v 0.20a) and the psu was set up with those parameters. The fan runs without problems.
2- old low power laptop (19v 4.74a max) so i ve set the parameters on the psu. The laptop tries to run but 5 seconds after, it shuts down and the psu stops working. Also, i tried set higher parameters on the psu but no change.
3- Gaming high power laptop (19.5v 11.8a max) in this case when i set the parameters of the psu to the required ones, the laptop doesent even starts, same hhappened when i set the max parameters aviable of the psu.
All mentiomed loads works fine with an boost buck converter that i have
I will attach a video so you can see, thx for the help 🙂
I tried to use it the same way (20V constant voltage). I set it to max output current (15.0A) but got no current when I enabled the output. I finally set the current limit to 3.30A and got some current. But the supply could not maintain constant voltage, and fluctuated from 17 to 20 volts, and switched continuously between CV and CC mode. This supply apparently cannot supply enough power to maintain, even if the CC is set as low as 0.50A.
