Can this be used as an external power supply for a device that requires 5V of external power? The device I have in mind is a Pro-Ject Pre Box S2 digital DAC. I am currently using the wall wart that came with it but wonder if this might offer an improvement.

What is the output on the unit? The output on the Volt are: • AC Output: 110V/85W Max • USB-C Output: 5V/3A • Adaptive Output: 5V/3A, 9V/2A, 12V/1.5A

As you've probably guessed, I don't understand the technology involved very well. I hope this answers your question. It is from the Tech Specifications of the DAC. Analogue outputs6.3mm Headphone (front), 1x Variable Out (RCA Output voltage 2.05 Veff  Outboard Power supply5V/1A DC (included)

I just looked at the rear panel of the Pro-Ject Pre Box S2 digital DAC and the power supply requirement which is Outboard Power supply5V/1A DC. If you current power supply use a micro USB input (typically a USB cord with a Micro USB connector) then yes since the Volt has two USB ports (2A and a QC3.0).

Thanks! Yes, the wall wart power supply I am currently using connects to my Pro-Ject DAC with a a micro USD connection. The other end of that cord is hard wired into the wall wart. So...I assume I would need a separate USB cable with a standard USB plug on one end (to connect to the Massdrop power supply being offered) and a micro USB connection for the DAC. Here is a further complication. As you can see on the back of the Pro-Ject DAC, there is also a standard USB connection and I am using that to connect the DAC to an ISO REGEN (a USB "purifier"). But that should not make any difference as I would just be swapping out the power supplies while maintaining the current additional USB connections.

  • Apologies! But one more question. I see that the power bank has this spec: QC 3.0 Output: 5V/3A, 9V/2A, 12V/1.5A
  • But the DAC power supply requirement you reminded me of is 5V/1A. Will the 5V/3A be a problem? I don't want to "fry" the DAC.

It has a 2.4A usb and a 3.0 QC either will work since the Volt has an IC chip (intelligent chip preventing overcharge). If you are still worried I just using the 2.4A output which is what an IPad requires.

correct you just need to buy a USB cable with a micro tip with the Volt.

In all honesty this unit is probably an overkill if your intentions is only to use with the device you questioned about unless you are going to use it for other charging solutions such as a laptop, phone, tablet etc. the great thing about it is the capacity and it’s versatile uses.

I thought the battery was too large to fly with.
