LEDs and Arduino Microcontroller, How much Ampere, is it safe?
Consumption:

144 Leds * 60 mA = 8,640 mA, running at 5 V


This is if you put them all parallel. Calculating the power:

P = V * I = 5 * 8,640 = 43 W)


By using a higher voltage (e.g. 24V):

P = V * I &lt;=&gt; 43 = 24 * I =&gt; I = 43 / 24 = 1.8 A


I'm sure you can get an adapter that can plug into a wall outlet for 2 A (or 3A or 4A if you want to be safe).

On internet there are plenty examples how to divide led strip(s).

(also I think 60 mA is quite a lot for a LED, I thought simple 3mm leds should be given max 40 mA, but maybe you have better ones).
