## Questions & Answers

**Q: How many can you daun together and still be effective?**
A: CTEK recommends using only one extension cable (56-304) with your charger.

**Q: Do you sell these in longer length?**
A: Have to buy the extension.

**Q: When using the interior Cig lighter plug, can you gently close the door over this or does it need to be fed through an open window?**
A: I gently close the door on mine -- it is not crimped in any way.  Been doing it for 3 winters now with no issue at all.

**Q: Does this work for the ctek MXS 5.0?**
A: Thank you for your interest in Euro MotoElectrics.

Yes, the extension will work on your CTek MXS 5.0
