Does anyone know what model or type of adaptor I can purchase for my Dell Inspiron 13-7368 laptop for the power inlet so that I connect onto my external portable power unit (The connection to the power unit is USB)?
I do not have knowledge of how those the Dell power inlet are being classified and I cannot locate the specification for it. The AC Adaptor that I have for the Dell laptop is model HA45NM140. The information maybe on the AC-Adaptor but I do not know what I am looking for in regarding the plug in type for the inlet of the laptop.
You cannot power or charge the system over USB. If you need some type of power source, it'll need to be an inverter that can supply the AC requirements of the AC adapter you use (you will still need the adapter).
