Can a LED drain a battery?

    I just installed an aftermarket USB port and a 12V outlet in my camper shell.

    I specifically wired them so they will always be on, so I can charge my phone and other electronics during the night when I'm sleeping.

    I do not have any sort of dual battery setup.

    I noticed when I hooked everything to the battery both the USB and the 12V have a blue LED that is always on.

    I will sometimes park my truck for several days at a time without driving it.

    Will these LED's drain my battery to the point my truck won't start?

    Thanks.

    Possible? Yes. They are extremely low draw, so a few days shouldn't be an issue. I'd wire in a switch. I also have a Solar powered Battery Tender for when I park my truck or other vehicles. They work great. I put it in my windshield.

    I have a couple of these, they work great.
