m16 R2, charging while powered off via USB-C?
Hi there, just wondering whether Alienware m16 R2 is able to take charge from the USB-C port? I don't intend to use it while getting charge from USB-C as I understand the power requirement of it. However, is USB-C charging an option to top up the battery when it's powered off? What's the maximum charging watts (say 100w) for if it is possible?

The thunderbolt 4 port from your Alienware is designed to connect to a thunderbolt 4 docking station such as WD22TB4. The typical power delivery from these docking stations is 130w to Dell systems and 90w for non-Dell systems. Hence, the suggestion to use up to 130w USB-C charger was taken safety into consideration.

There is no official support for USB-C charging on this system. However, trickle charge with USB-C while the system is off should be possible. Use the thunderbolt port as it's wired for power delivery.
Since it's a non-support method, there is no guideline for the maximum power requirement. You can attempt with 130w USB-C charger, preferably Dell brand charger from XPS and Precision product line.

Thanks Chino, i'm just a bit afraid that it would damage the motherboard or battery with 100w plus attempt so want to double check before trying. the usb c thunderbolt port is set up for PD charging external devices but it looks like that's below 30w output? would it suggest the same for input limit?

I can see in the manual for this system that it can do up to 15 W power share through the thunderbolt port, but I assume that means output, so to charge a phone or whatnot. Is there any documentation that officially states what it can handle for input? I have a nice 100W Anker USB C charger that would be lovely to use instead of the big brick for evening work from home tasks or quick backup power during meetings. I also have a Dell WD19 dock in my office that would be nice to have as backup input in case I forget my charger or something.

Dell coded their system BIOS to detect and accept Dell OEM chargers. If you use a third party power adapter, it may be accepted at a lower input wattages or right out rejecting it. Therefore, can not give you a definitive answer.
However, you can always performing a test. Boot your system into BIOS settings, then plugging in the Anker charger. Observing to see if the charger can be recognized in BIOS and the accepting wattages.
