Powering a raspberry pi 3.

Ruben360

Hey,

its recomended to use a 2.5A@5V charger to power a raspberry pi 3. Is it ok if I use my 4A@5V phone charger to power it? Or do the extra Amps damage it?

I need a quick answer.

Thanks!

I use a 2A charger for my r-pi 2B, which works good, I think a 2.5A is the best for a r-pi 3.

btw, how can your phone survive a 4A charger?! my phone already has struggles when I use the 2A charger for it

you can use a 4A charger.

I have never heard of a 4A charger. Are you sure its not 0.4A?

If the charger is rated less than the rpi then the charger will be damaged/catch fire/pull a samsung Note.

My phone supports dash charge which is pretty much the fastest chaging technology

more As wont hurt it but you dont need 2.5A for a p3 if you dont have a bunch of things hooked up to it - I think my could work even on 1 (or 1.5 dont remember) without my 7inch touch....

An electrical load only pulls as much current from the supply as it needs. The current rating of a supply is the maximum sustained current the supply can handle while functioning properly. So if you have a 2a load and a 90a supply, you're only going to pull 2a from your supply despite having the capacity for 90.

I use a 3 amp 5v charger so you should be fine. Those extra amps wont effect it but will actually help if you overclock it.

The only reason I'm here is that I have homework that I don't want to do
