## Questions & Answers

**Q: Does the device need to be connected to the mains when in use and the car is not being used for a few days?**
A: The idea is that you leave the device connected to the car and mains when not in use to keep the battery consistently charged. It can stay in the car near the battery pack ready for use.

**Q: The description for the noco genius2duk says it has a battery repair & conditioner mode, yet the comparison table says it doesn't - which is it ?**
A: The GENIUS2D desulfates during both the 12V and 6V charging modes. It is one of the first few steps in the charging process, if the charger detects sulfation in the battery it will automatically start desulfating during the charge, there is nothing that you need to do to activate it. The 12V Repair Mode that the larger models have is an additional mode dedicated to recovering heavily sulfated, stratified, old, damaged, and/or idle 12V batteries.

**Q: Is any using adhoc rather Onboard?**
A: Most modern cars come with modular battery’s and are covered. The idea of these units is to add a battery charger that doesn’t need to be disconnected every time.  You’d just plug the charger into an extension lead which you’d keep dry under the bonnet.

**Q: I want to connect it to a power inverter in my car's boot. Will it draw much power just to trickle charge my additional battery?**
A: The NOCO Genius chargers have not been tested to be powered by inverters or generators. In theory, it will work as long as the power requirements of the charger are met. I have listed the power requirements below for the charger, including the max amperage draw of the charger.

Working VAC: 120-240 VAC, 50-60 Hz 
Max Draw: 28W 0.12A @ 240V AC.
