Input: 100V-240V 50/60Hz; output: 12V DC, 2A max; Works with device that draws less than 2A, such as 1.1A, 1.2A, 1.4A, 1.5A, 1.8A, 2A.DC plug connector external diameter is 5.5mm, internal diameter is 2.1~2.5mm. Comes with a female DC barrel connector. You can easily screw wires on it without soldering.Safety protection: automatically overload cut-off, over voltage cut-off, over temperature cut-off, short-circuit cut-off.Sufficient 24W output power and stable 12V output voltage will protect your electronic devices from destruction.It is perfect for 12V devices less than 24W, such as LED light strip, CCTV camera security system, Bluetooth speaker, keyboard, TV boxes, webcam router,etc.
Ahh.. that can be beautiful if you can put each LED in a hole with all the wiring below. Those LEDs that you linked to are 12-volts. You can easily run 10 of them on a 1-amp power supply This 12-volt supply comes with a connector for bare wires. You will need to wire the LEDs in parallel for this supply. Be careful of polarity--red to + black to -.
Actually you could probably use a phone charger (5 volts, USB) but your lights would not be as bright since they have built-in current limiting resistors designed for 12 volts.
Hope this helps.
