Inspiron 13 (7373, at least) will definitely charge from

My 7386 definitely charges with my 130 watts Dell 15 dock Charges and runs without battery losing any charge.

If you’re referring to the WD15 dock and you have a 130W power supply connected to the dock, then the WD15 can send up to 90W to the attached system. That’s more than enough for a 13-inch Inspiron system.
