Can I use one of those generic A/C or D/C power adapters with my QChord? No. You should use only the specially designed power (A/C) and cigarette lighter (D/C) adapters, or risk possible damage to your QChord.
This is because the QChord uses reverse polarity adapters; that is, the center pole is negative and the outer sleeve is positive. The correct adapters are available on our accessory page in our QChord Store.
The AC adapter designed for the QC hord has the following specifications.
- 12 Volts DC
- 500 ma
- REVERSE POLARITY (center pole negative, outer sleeve positive)
The QChord will function with a little lower voltage and/or current than specified. But since the polarity of the QChord adapter is opposite to that used on most adapters, it is VERY IMPORTANT to make sure that any substitute adapter meets the polarity requirement. Otherwise the QChord will not function, and there is the possibility of damage as well.
