Common Questions
Is it suitable for powering an LED light strip?
If the current needed by the strip does not exceed the power supply's rating and the barrel connector mates with the correct polarity, these can be used to power an LEDs light strip.
Can you offer a discount if I order 100 pieces?
If you can order 20 QTY, we will give you 5 pieces for free, thanks a lot and always here for you.
Is the center positive or negative?
Yes, the center positive and outer negative.
Is it possible to confirm the input voltage range?
I can't say if the Adapters work at the 220V/240V input rating because I have only used them at 110V / 60Hz.
Do you have a 9v 1300mA for a speaker?
I don't use them for speakers. I use them for lamps.
