## Questions & Answers

**Q: if low voltage cutoff is reached, how much is the power consumption? I have a cigarette outlet that is always on. Afraid of batt drain even on cutoff.**
A: There is a power sensing circuit that remains active all the time but it draws so little current that I don't notice any difference between the unit being plugged into a 12 volt socket and it being unplugged. I rarely unplug mine. I only unplug it if I don't plan on using the car for several weeks and even then other parasitic draws in the car typically drain the battery down. This is the best solution I have found to solve the problem of 12 volt sockets that are unswitched.

**Q: Okay I'm glad to know the length of the cable, but what's the actual control box itself The height and width? The control box from which you control**
A: Controller Dimensions are 3.3in(8.5cm) Wide, 1.1in(2.8cm) Tall, 0.5in(1.2cm) Deep
Controller wire length is 47.2in(120cm)
Cig power wire length is 33.5in(85cm)
3 Cig Splitter Main Box is 4.3in(10.8cm) Long, 1.3in(3.3cm) Tall, 1.9(4.8cm) Deep

**Q: Hello, how do we get the temperature sensor? Thank you**
A: Hi that would be: B07BR6NZQY
https://www.amazon.com/dp/B07BR6NZQY

**Q: Plugged into an always on socket, If the auto voltage power off happens due to voltage drop, will the unit power on when voltage returns to normal?**
A: The unit has an on/off switch along with a touch switch for each plug. I use mine with my dash cam since my plugs are always hot.
I just turn it off when I reach my destination. 

A side benefit is that it has a display for voltage. You can see battery voltage and engine output while driving.
