WD19, Docking station
I’ve bought dock station wd 19 with power adapter 130w and it’s not enough for my laptop XPS 15 because it’s work with low performance.
Will dock station wd 19 work properly if I change the power adapter to 180w?

@BulletEMF as long as it's an official Dell/Alienware power adapter of at least 180W and the connector physically fits, then yes that will work. Dell standardized all of their barrel-style power adapters to deliver 19.5 V a long time ago and has stuck to that ever since. The different wattage levels are achieved by increasing the available amperage, but voltage is always the same. The only other difference has been the relatively recent introduction of a smaller barrel connector for certain systems (and USB-C power adapters, but that's a whole other thing). The end result is that Dell barrel-style power adapters are highly interchangeable. Since the voltage of all power adapters is consistent, using a higher wattage power supply than you need is fine and won't hurt anything because the powered device will only ever draw the amperage that it actually needs. The power adapter won't "force" the device to accept more amperage than it actually wants or can handle.

@BulletEMF yes. The 130W version can only pass 90W through to the attached system. The 180W version can pass 130W through, which is what the XPS 15 is designed for.
And depending on the display setup you plan to run, you might want to consider the WD19TB. The current XPS 15 models are HBR2 systems, which means the WD19TB can tap into 4x more display bandwidth than the WD19 when used with an XPS 15, and therefore it can run higher-end display setups. The WD19TB always comes with a 180W power supply, FYI.

@jphughanThank you! That's cool if I can change only adapter without buying new dock station.

@jphughanCan you please tell me one more thing - if I will use power adapter from Dell Alianware will it works? Power adapter from Alianware has same size of connector 5mm x 7.4 mm as dock station adapter.
