I'm now quite good at DJing and accordingly I do it more often with or for my friends. We meet, I'll throw something nice in the boxes and we have a great time. The problem here is the electricity. Until now we always had a generator or a fixed power connection.
Since I now also have a smaller DJ controller and we can listen to loud music with the Soundboks even away from the power supply, I wanted to look around for a way to make the whole setup mobile and independent.
The laptop has a battery, the Soundboks has a battery, so now only the DJ controller needs to be powered.
Now the question: is there a way to take electricity with you and tap it through a normal socket connection. A cheap DIY solution would be best. Can you somehow connect a car battery or a fat battery? Does anyone have any experience? As I said, the controller is not big, so it consumes little. It must be possible somehow.
There are inverters from 12V to 230V… But the inexpensive ones are only trapezoidal inverters (quality of the generated AC voltage) … I don't know whether the electronics like that. Then it depends on the consumption of what the thing actually has. The size of the inverter and the battery required to achieve the desired runtime are also based on this.
There are also power packs with a socket as a combination. But not exactly cheap either. Does the part have an external power supply unit or a 230V connection cable directly on the device? Maybe there are other solutions (to generate a power bank with a low voltage output instead of 230V and to hunt it again over a power supply unit to turn it into a low voltage…
Now the question: is there a way to take electricity with you and tap it through a normal socket connection.
But you already know that batteries deliver direct current and that 230 volts alternating current come from the socket?
That means: You need a device that converts the conventional batteries you brought with you (e.g. Car battery with 12 volts direct current) back to 230 volts alternating current.
There's such a thing, but the devices in question are of course not free and the degree of efficiency is also unlikely to be the best.
Search for https://duckduckgo.com/?q=Auto+230+Volt+wechselrichter on the Internet, you should find appropriate devices.
I would spontaneously think of a UPS.
What kind of DJ controller do you have? It will run internally with a very low DC voltage. It would make no sense to bring the voltage of a battery to 230 volts AC with 50 Hz; to let the power supply unit of the device bring it back to a few volts DC.
The controller has a power connection and an internal power supply I assume.
Then you can only operate it with a battery if you connect an inverter, which turns the 12 V direct current into 220V. If it has an external power supply unit and it is labeled with an output voltage of 12 V direct current, you can also operate it with a 12 V car battery. To do this, provide a cable with the appropriate connections.
However, a suitable fuse must be interposed because without it the controller would burn off in the event of a fault.
The controller we would use for this is a Numark OmniControl. Ancient thing, but works fine and draws little electricity.
At the back of the socket for the power supply is written "DC IN - 6V / 1A"
So you don't need a 230 volt AC voltage. 6 volts DC is sufficient and the device only draws 1 ampere. One could e.g. Tinker something nice out of five D-cell batteries.
