What are the specifications of the Handy BoardsDC adapter?
• 12 volt, 500 mA DC output • 2.1 mm inside, 5.5 mm outside diameter barrel-type plug • center conductor negative Most “universal” type adapters will work properly at one of their settings. Look for the yellow charge LED to light up indicating proper charge (make sure the Charge Rate switch is set to “Normal” mode). Please be careful not to get an adapter that is overpowered. Problems have been reported using adapters that are rated for 1 to 2 amps. Also, do not use an adapter that is underpowered or undervoltage. A 9 volt adapter will appear to work—the charge LED will light—but it won’t be able to charge the battery for more than a few minutes’ worth of power. Finally, do not use a regulated power supply. Use inexpensive, unregulated wall wart type adapters only.
