Hi all,

Just want to check my understanding of amps with respect to charging electronic devices.

I have devices I need to charge, which have the following ratings on thier AC power supplies:

1) 5v 0.7A
2) 5v 3A
3) 5v 1A
4) 5v 0.7A

My understanding is that I can power all of these using a 5v 1A power pack, it just means the 0.7A ones will charge slightly faster and the 3A one will take 3 times as long to charge.

Is this correct or am I going to blow something up?

Do I need to find a charger that outputs at the lowest common denominator of 0.7A ?

Thanks,
Roger.
