Charging via USB-C port

Hello, can the Inspiron 15-7580 be charged via the USB-C port? I cannot see anything confirming this in the documentation. However, it seems that Dell sells a charger for this: https://www.dell.com/en-us/member/shop/dell-usb-c-power-adapter-plus-45w/apd/492-bbwz (Inspiron 15-7000 series mentioned at the bottom of page on the compatibility list) And in France, I see the (same?) charger is on sale : http://online-go.fr/dell-adaptateur-c-10/dell-inspiron-15-7000-7569-chargeur-original-45w-usbc-p-406... Can anyone confirm this one way or the other? Thanks.

Re: Charging via USB-C port

Looking at the Specifications document for that system on support.dell.com, specifically the sections that mention the USB-C port, there’s no mention of support for charging. Typically the documentation and products pages of systems that support this say something like “supports system charging / DC-in” in the notes about the system’s USB-C port(s). So my guess is that the system doesn’t support this. I wouldn’t put a ton of faith in the compatibility list on the charger product page. Those lists often omit compatible systems or list incompatible systems. Also, the Specifications document mentions both 45W and 65W chargers for that system, probably depending on the options your system is configured with. I would check the wattage on the charger you received with your specific system. If it’s 65W, you’d need a 65W USB-C charger anyway. I actually have a Nekteck 65W USB-C charger I’m very happy with if you decide to test this yourself. I also bought a 10ft USB-C cable since the included 6ft cable was shorter than the total cord length of my system’s charger. If you want to do that too, make sure you get a USB-C cable rated for up to 5A / 100W, because otherwise it will only carry up to 60W.

Thank you for all that. Well I shall look for a shop where I can test it out before buying -- not sure how easy that will be.

Re: Charging via USB-C port

Well I finally managed to get to a shop in London where they were happy to try it out. So we tried it with a 60w charger they had in stock. In the BIOS we got the message that we had attached a power supply inferior to the required 65w. When we booted into Windows there was a message that the computer was charging, however that the supply was not as powerful as it should be and tha some power might still be taken from the battery. So the answer seems to be for my Inspiron 15-7580 system is that USB-C charging does work, despite there being no mention of it in the Dell specs. Very happy Smiley Happy

Re: Charging via USB-C port

I have recently purchased a Inspiron 13 7000 2in1 (7386) and have been attempting to get a 'straight answer' to if this can be charged through USB-C?

My thoughts after a lot of exchanges with Dell support is that nobody knows the answer. It just seems strange to me that some models even older ones can (7368 is quoted for Dell part 492-BBWZ 45w & 7389 for Dell part 492-BCBI 65w) but there does not seem to be any confirming answer when it comes to the 7386.
