I bought the single, USB unit and installed it in my RV. The "parasitic" draw is negligible if you are not charging anything; just a single small LED, and likely much less than the 12VDC meter's multiple LED segments. Actually, the only downside to the USB section is that the LED is bright and on all the time. I mounted it inside a cabinet, so it's not an issue, but it would be annoying at night otherwise. Personally, I love having the double USB port; no more bulky cell chargers plugged in every available outlet!
