Default Need battery maintainer advice

My C8 is on order so I'm shopping for the extras.

I would like a battery maintainer and in my readings here I settled on the NOCO GENIUS10. But it does NOT have a 12v cigarette lighter adapter (not sure of the term used now).
The C8 does have one of these in the frunk for such usage correct?
Should I look for a different charger? I'd rather not have to 'get to' the battery every time I want to hook it up or unhook it.

Advice?

Thanks

Battery Tender Jr. Cheap and it works just fine. I modified the end to be able to plug into the charge port in the frunk. I see no need to spend $100 on a tender. Have used mine for years on other cars and two winter seasons on the C8 without any issue or concern.

Buy one with the cigarette lighter style plug included, or get the adapter separately, as you wish. There are plenty out there. Attached is the one I use. Note that they all will have a replaceable fuse in the plug.

OK...looking at CTEK and Battery Tender Jr.
Next question can either or both of these be used with a extension cord? Distance from outlet to car is too great to just plug maintainer in wall and have the wire reach the frunk.

Just get the NOCO adapter from Amazon, probably around $18 or order directly from NOCO.
