Charging dock for Spectre x360 15t-CH000

[garyfritz]

A year ago I got a Spectre x360 15, but for various reasons had to return it.  While I had it I started researching USB-C charging/display/USB/audio/etc docks for it, and I discovered most docks wouldn't properly charge it.  The x360 would complain about a non-HP power supply.  If I remember right the x360 13's didn't have a problem but the 15's needed more juice than most docks provided.

I finally got myself another x360 15 (product 2FW62AV) and I still want a dock.  The supplied charger is rated 150W (19.5V, 7.7A).  Does that mean the dock must also be rated for 150W?  Most docks I see on Amazon are rated for only 60-80W. Is there any dock option that will work, hopefully for less than $200!?  I may end up getting a non-charging dock (a lot cheaper) and just use the supplied charger for power.

Actually I would be perfectly happy with a charger that would **maintain** a full charge, even if it couldn't charge up a drained battery, especially if that was gentler on the battery and meant it was safer to leave the laptop always connected to the dock.  Replacing the battery on this thing will be a serious PITA and I'd like to delay it as long as possible.

Normally charging dock MUST have wattage higher than the supplied charger. All my charging docks to date have up to 50% more power than the normal chargers because they have to supply power to drive other peripherals.

OK, what docks are you using?  As I said, all the ones I found were in the 60-80W range.  I didn't do an exhaustive search but it would help to have some pointers to where to start.  Thanks!

And if they're as $$spendy$$ as I suspect, I will probably just go with the "cheap expander dock and use the stock charger" solution...
