|I'm suprised how many people, when scrounging around for an adapter/charger, will use anything as long as the plug fits the jack. The label on most chargers gives the polarity, voltage and maximum amperge.|
Some universal chargers have a removable tip that allows you to change polarity.
Those are the things a person should check before using them on any device.
Don't forget to preorder your Hatch green chili for this fall. Many vendors ship world-wide.
