Belker 30W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter with 8 Tips
Bottom line: The Belker 30W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter: Seven switchable DC voltages (3V-12V) plus 8 tips replace a drawer of dead adapters; main trade-off: center-positive polarity only; center-negative gear needs Belker's separate reversal cable.
