This water pump is 12v dc, Can i power it using usb then connected to power bank or computer?

The simple answer is NO.
A USB provides only 5 Volts DC, and cannot handle more than about 2 Amps.
You can use a Switching Voltage convertor to provide 12 volts from the 5 volts, but what is the current required by your pump? The USB will need to provide 2.5 times that current; can it?

 

Hello,

In the given link there is no information about the power rating of the pump.
Keep in mind that the USB port of a computer has a very limited output.

I was testing some motor in here and both works in 12v and 5v so i was thinking maybe this will work too

So if i use this 12v motor in 5v usb, maybe the motor in air pump runs slower?


the air pump only indicates 12v, dunno about more details on it

 

If you run then motor at a lower voltage, it may run, but will draw more current and run hotter. It may stall on load leading to permanent damage to motor and / or power supply.

 

Some air pumps are extremely efficient.
We use the air pump linked below our portable bait bucket and their battery life claims of 40 hours on a pair of D batteries (in parallel) is believeable. It seems to run forever on a single D cell. One of these should easily run from a USB power source using a buck converter to get down to 1.5v. Water pumps take a lot more energy though.. Why are you targeting USB as a power source?

Probably a good idea would be to get a 12vDC power supply such as this:

and a water pump such as this:

...with the water pump with a power consumption of 3 Watts you would only need a 1 Amp power supply.

 

Hello,

What kind of pump are you trying to use?
In post #1 you are showing a waterpump.
In post #4 you are talking about an air pump.

A waterpump will consume much more power as an airpump.

A simple 12volt secondary transformer and a bridge is all you need.

hey everyone, thanks for your fast response

just answering some few Questions from the commenters:
*I want it to power usb because the little aQuarium i have is beside my pc and not to mention I want to power it to powerbank or my pc instead of a wall outlet which is very dangerous if the water touches it.
Airpump or waterpump, i saw some diy and you can use airpump as waterpump too.
I can actually power the 12v water pump using my power supply. Connect it you yellow wire which is 12v but as I said, I dont want a wall outlet or power supply just to power a water pump and my aQuarium is not that big actually.

So where is the PC powered from?
Actually a 120/240v transformer with 12v secondary offers galvanic isolation, you can also connect the 12v COM to earth ground, the same as your PC P.S is for safety.

how about this bro?

Ill use a booster
https://shopee.ph/8W-USB-Input-DC-D...wer-Supply-Boost-Module-i.56540719.1005401202

5v to 12v

Will this work?

my pc is powered with my 700w power supply, I have a spare pwoer supply im not using and use it to power my peltier module and some gadgets that I test but not permanent power source though

 

Only 8W!

If you do end up connecting the water pump via a USB connector.. Do not forget that the water pump will only operate when the PC is on.

ya 8w only. i think the water pump is 3 or probably 2 amp draw

i have alot of power banks

so my plan is solar power>powerbank>waterpump

 

ya 8w only. i think the water pump is 3 or probably 2 amp draw

That is 24w to 36w!

Then think about a 4-6vDC water pump with a USB connector such as this:
