I've got a 5v (2A) power source, different electronics hooked

>What is happening?
What are you doing?

Ill post a kindof diagram of the setup. Basically i've got a subwoofer with a 5v phone charger which i put in it. Stay with me, diagram in 10 mins tops

pls halp

Supply doesn't provide enough current

>>1028110
It's the remote switch that turns off, why does everything work when i have plugged the phone in? (this project is mainly based on basic knowledge, don't know much but trial and error right)

>>1028110
this.

modern phones use close to 2 amps while charging.

you need:
1. a separate charger for your phone
2. higher amp power source

>>1028113
How can i determine how much Amps i need (without the phone then)

btw, with 5V remote switch, do you mean a relay? you might fry your electronics with the inductive spike if there is no suppressor connected

>>1028117
yes, tell me more?

>>1028117
>>1028122
also can you tell me what i should put where to prevent it?

When you cut the current of a coil the energy of the magnetic field gets dumped back into the circuit. This can create ridiculously high voltages. To prevent this you can connect a diode parallel to the coil. shitty pic related

I am researching right now, but I'm too dumb to see where in my circuitry I'd need to put a diode, and which diode I need :S

Am using this exact relay switch thing. Maybe it has a supressor built in? Can you tell?

>>1028139
Yes, nothing to worry about then.

>>1028140
Its the "D1" on the right side isn't it?
Also if youre the same dude who answered the rest of my questions, thanks a lot.

>>1028131
Across any relay coil, from negative to positive.

Wow didn't know my 800 milliamp phone charger equaled to 2 amps! Thank bud for that awesome assumption!!!

>>1028156
>>modern phones
there's the difference

>>1028156
There's a good chance you have no idea what you're talking about.

Amps are pulled, volts are pushed. Please.
This means your phone asks 2A, but only gets 0.8A. It will charge, but at a slow rate.
This also means that OP's circuitry asks for lets say 1.5A, and his phone asks for 2A, so the adapter he uses gives up because it cant deliver 3.5A.
