The amperage of the AC Adapter has no effect on the lifespan of the LEDs. If you gave the LED strip too much voltage however, it could shorten the lifespan. <br><br> You can think of it like this: a kayaker in a river. Suppose the width of the river relates to the amperage, and the speed the water is flowing relates to the voltage. The kayaker doesn't care how wide the river is, as long as it is wide enough for his kayak. If you want 50 kayaks to be able to go down the river at the same time, you'll need a wider river. Same with the LED strips - if you want more LED strips to be on the same AC Adapter, you'd need a larger amperage AC Adapter. <br><br> Suppose the amperage your LED strip uses is 100 mA. That means your 2 amp adapter can handle 20 strips. <br> Suppose the width of the kayak is 10 inches. That means a 200 inch wide river could handle 20 kayaks floating down at the same time.</div></div></div><div class=cus-faq><div class=row><div class="col-sm-1 hidden-xs">Q.</div><div class=col-sm-11>How long is the cord running from the adapter...the 2 amp one that is</div></div><div class=row><div class="col-sm-1 hidden-xs">A.</div><div class=col-sm-11>About 2-3 feet.</div></div></div><div class=cus-faq><div class=row><div class="col-sm-1 hidden-xs">Q.</div><div class=col-sm-11>why wont my fan run.

It steps down input voltage from 110V - 220V AC to 12V DC output voltage. Oznium's efficient switching adapters are available in three convenient amperage's to suit your project needs: 2 amps, 3.25 amps, and 5 amps. Dimensions: 2 amp = 1-3\/4 W x 3-1\/4 L x 1-1\/8 H 3.25 amp = 1-3\/4 W x 4-1\/2 L x 1-1\/4 H 5 amp = 2\" W x 4-1\/2 L x 1-1\/4 H Which amperage is right for me? You first need to figure out the total amperage draw of your LEDs. Suppose you are powering 16 feet of our LED Ribbon Strips which use 130 mA per foot. Note: mA is an abbreviation for milliamps, and there are 1000 milliamps in an amp, so 130 mA = .130 amps 16 feet x .130 amps = 2.08 amps While the 2 amp AC Adapter would work for this application (16 feet of LED Ribbon Strips), it would be at the limit of its capabilities. The LEDs may not reach their full brightness potential, and the 2 amp AC Adapter may work harder ","aggregateRating":{"@type":"AggregateRating","ratingValue":4.8,"reviewCount":5},"review":[{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"5"},"name":"Excellent ","author":{"@type":"Person","name":"Adrian Silva"},"reviewBody":"Exactly as advertised.
