## Questions & Answers

**Q: Can i use this to supply a device requiring 0.4-1.0a 12v dc in?**
A: Yes, it can.

**Q: What is the cable length?**
A: The low voltage DC output cable is approx. 1.48 metres from mains unit to the end of the 2-pin socket. There is no input mains lead as the 13A plug forms part of the mains unit itself, which is of the nickname 'wall wart' type.

**Q: WHat is the length of the barrel**
A: The length may be inconsistent, attach the size and length of all plugs: 5.5*2.5mm 12cm; 2.5mm 12mm; 3.5mm 14mm; 4.0*1.7mm 12mm; 3.5*1.35mm 12mm; 5.0*2.1mm 12mm; 5.5*2.1mm 12mm; 5.5*1.5mm 13mm

**Q: Is the output voltage regulated? ie. if variable power is drawn by devices (such as musical keyboards,) does this change the voltage?**
A: It actually depends on if the currect your device draws is stable or not. From what you mentioned, there is two possibilities when the total power consumption is variable, one is the regulated voltage output with changeable current, another is un-regulated voltage with stable current. This power adapter belongs to the second situation, the voltage output may drop or up within 5% range, not actual 12V(11.9V or 12.2V) when you adjust the voltage knob at DC 12V setting. Hope this may help you.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Far less unsafe than some suggest when properly connected and set-up
*by L***R on 7 January 2022*

This is designed and intended for use as a power supply and not a recharger. It is designed for use with a variety of electronic devices whose power needs fit within the 3-12V at 2.5A range (or lower current levels) and where it can replace or be a permanent alternative to disposable or rechargeable batteries.The "SoulBay 30W Reverse Polarity Universal AC Adapter Multi Voltage DC Power Supply, with 9pcs Adaptor Tips, Compatible with 3V to 12V Household Electronics, 2Amp Output" supplies voltages mostly stepped at 1.5v intervals in well-marked and positively engaged steps when set by the enclosed key - a medium flat blade screwdriver will work equally well. It is unusual in that it has a means to reverse the polarity of the output voltage such that the numerous devices with a positive centre core connector are readily accommodated but, by reversing the tip, allows the relative few with a negative core to also be served.Some reviews appear to suggest that it is potentially dangerous to use, not to the user but to devices, because there is no certainty about tip orientation. That is INCORRECT and MISLEADING! The output lead is clearly labelled on its 'normal' side and provides a positive core when a tip is properly connected. Each tip is also very obviously labelled on both larger surfaces, one showing the core as positive, the other negative. It could not be much clearer unless in flashing red neon!In addition to subsequently purchasing one for personal use, one identical was first purchased by a family member as a power source for a single device, the alternative being an OEM PSU at more than twice the price as it requires a negative core supply and they are almost impossible to find as third-party alternatives! It was set up to meet its specific voltage and polarity needs and works perfectly.The tips are a very tight fit and need to be firmly connected until fully engaged - they will not easily accidentally disconnect - it needs a strong grip! The voltage dial, once set, will stay as-is and cannot easily disengage without the aid of the key or a screwdriver.Safety considerations are better implemented than with a similar product from another brand where its tips use an easily disconnected co-axial method and voltage adjustment is by a large knob whose position could be easily altered by a careless touch, passing pet or young child and pass unnoticed, risking the device should the voltage supply be beyond its limits - it does have a small LED display for output voltage but that cannot prevent an accidental voltage increase, only show that it occurred.

### ⭐⭐⭐⭐⭐ Works just as it should.
*by D***Y on 21 May 2025*

Does the job. Just used for a couple of weeks. No issues. Full range of voltages available to be able to run small battery powered equipment from mains power.

### ⭐⭐⭐⭐ Provides Power for various devices
*by B***E on 9 February 2025*

Works well, the only thing that would improve it would be to be able to change the power settings without the special key provided. Like a slider selection switch. That would have made it 5 stars.
