I am making a mobile phone charging unit, we pay for power in 16amp supply or 32 amp supply.
32 amp is crazy money.
I wish to know if anyone can help .
How many mobile phones etc can I charge with a 16amp supply.
I bought a cheap amp tester , this said 1 iPhone draws 0.09 amps but this may not be correct.
Um... What is the voltage of the 16A supply? Give me a link to that charger.
For charging the "normal" phone you would need about 2,5W (0,5A @ 5V). For Iphone, you would need probably around 5 - 7,5W (1 - 1,5A @ 5V).
