Dell Inspiron 15 3531 won't support new universal replacement charger

Had to replace battery charger for Dell Inspiron 3531. Bought one from Best Buy (was a universal type, with different adapters), plugged it in, and the laptop would not support it, wouldn't charge. I can't find an original Dell charger online, just more replacements. If I buy a replacement OEM type, will it work, or will it not be supported too?? I don't want to waste time and money ordering chargers that will give me the "not supported" message.

Is this a good question?

@volzster what are the specs of your universal charger?


I returned it, so I'm not sure, other than I do know it was 65w, which is what is required for the laptop.


@oldturkey03 , what I'm basically wondering is will a non-Dell made charger, that is an OEM replacement, work. I know with some electronics, they are made to only accept their manufacturers parts/accessories.

I'm assuming that because the one I purchased was a universal charger with interchangeable port adapters , that it may have been the issue, because it was made for several types of laptops instead of just the Dell.


The correct specs can be taken from your old charger. It will have a sticker on the bottom stating rated output voltage and current, as well as the DC plug polarity.
