If this is not the right place for this question, sorry and please direct me to the right place!
I have a Dell Precision 5540 laptop, which has a 130W AC Adapter.
Input = 100-240v~1.8A 50-60Hz
Output = 19.5V == 6.67A
I wanted a docking station to plug in all my peripherals and so got a Belkin Thunderbolt 3 Dock Pro. However, I did not consider the charging. I believe the docking station is capable of charging a laptop however, when I plug it into mine, I get a notification on screen stating the laptop is not being charged. This is fine with me because it's easier for me to plug in my external laptop charger than order a new "compatible" docking station.
According to the charger brick that came with the docking station, the power specs are as follows
Input: 100-240V~2.5A 50-60Hz
Output: 20V == 8.5A
My question is this -- Is it dangerous to plug in my docking station AND my external laptop charger to the laptop at the same time? Although the laptop does not get charged with only the docking station plugged in, I assume it's still receiving the power. Along with my external charger, I am afraid it may be receiving way too much power? I know nothing about this topic, please correct me if my assumptions are wrong. Many thanks! :)
