## Questions & Answers

**Q: Is this suitable for powering an LED light strip?**
A: Be careful and note the low amperage delivered by this power supply. This only puts out one amp or 1000 milliamps.  I was thinking about getting this and checked my LED semi-concealed light strip's power supply.  It says 6 amps, not 1 amp.  You can have a device that draws less amps than your power supply and everything will be fine.  If something draws more amps the power supply will struggle and likely overheat.  Even if it works, it will fail early.  No matter what length you might 'trim' a light strip to, you should still be able to supply at least as many amps as the original supply and if you have more amps available in the power supply that's fine, the device just won't use them.

Don't guess and hope you're within the parameters of your power supply.  Either check the manufacturers specs online or look  at the old, failed power supply for specifications.  Too many amps are OK, too many volts (or too few) are not.  Too few amps (1 Amp = 1000 Milliamps) is not OK under any circumstances.  You could fry your power supply, damage your device, have a fire or melt down your power supply.  Fire is unlikely but possible, the more likely outcome is damage to your equipment or loss of the inadequate power supply due to early failure.

**Q: I would like to order 100 of these do you have a listing for such?**
A: hi this qich seller from hong kong , you can choose the QTY of the listing , and if you can order 20 QTY(100pcs) , we will give you 5pcs (1 QTY)  for free , thanks a lot and always here for you

**Q: is the center positive and outside negative or the opposite?**
A: Yes center positive and outer negative.   That is correct.

**Q: Could you confirm the input voltage range?**
A: I can only confirm 120Vac use, as I have no 240 Vac to test. But Sticker says 100-240VAC ~ 50/60Hz.I have several brands of cameras and these P.Supplys are best I have.
