Great Device and Very Versatile
My grandson had lost the charger for his portable DVD player so to make him happy I told him that I would get a new charger for him. When this device came up it looked perfect for the job so I ordered it.This plugin unit is well made, feels solid and has no rattles or rough edges. To adjust the voltage there is an easy to use control on the underside of the transformer which is clearly marked. I set this to 9 volts which is what I needed for his DVD player and then tested the output with my multimeter which showed a reading of 9.2 volts and as this can handle up to 2 amps where I only needed 1.5 amps made this perfect for my needs. As the voltage control can be moved and I didn’t want him to blow up his DVD by turning this up to 12v I then used a resin to seal over the control so that it can no longer be changed, as my grandson is only four years old I thought this to be the best way.Along with the transformer comes an assortment of connectors, one of which was the exact one that I needed to fit his DVD player, so I connected that to the cable and glued it into place, again he is only four, so taking things to pieces is his favourite pastime at the moment, lol.The other connectors that come with this will fit anything that I have seen but incase you have a connector that ins’t supplied then it still comes with a two core wire adaptor to allow you to manually connect a cable to this unit.This is a terrific unit and is good value.Recommended.

Single Adapter For All Devices
Review for 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.With several devices where I have lost original power adapters, with different voltages it’s a challenge finding suitable adapters. This kit comes with not only changeable voltage transformer but also comes with several different tips which allow connection to many different connector type. This does away with the need for multiple adapter to support different voltage and connectors, this one transformer is all you need.This also supports reverse polarity which on one or two devices is the case. Cant’ comment on values as no published selling price at time of review due to availability.

Reverse polarity adapter with 9 Tips
Delivered by Amazon in a plain cardboard boxInside the box there is a 30w plug that comes on a long lead , and a packet filled with 9 different adapter tips and a key for changing the polarity on the plug . These adapters are suitable for use with routers ,speakers monitors led strips and other household electronics . So if you e lost a lead you don’t need to buy a new item just use this plug .I’m uncertain why my son wanted it I think it wafor his keyboard ,but he’s very happy and has taken it away with him .prime price is just £14.99 which is great value for money considering how versatile this is .Happy to recommend

Perfect for Guitar Effect Pedals
My main interest in this was for use with my guitar effects and it works perfectly – there’s no electronic noise – it allows your pedal devices to produce clean audio.The one and two star reviews due to polarity confusion (user error) are unfounded. The polarity marking are clear and explained well on the Amazon description page. It only took me a minute to see that there is an arrow mark on one side of the connector lead fixing that needs to be aligned with the adapter in the orientation that you need for the correct polarity.It’s a 2 Amp adapter so it can handle more than one pedal – I bought a daisy chain cable (5 pounds) that allows up to 5 pedals to be powered by this adapter.HIGHLY RECOMMENDED! AAA+++

Watch the polarity
As a guitarist, I have a pedalboard that needed a new 9volt power supply. As this can be switched into serval configurations this was no problem,. Selecting the correct tip was also easy by looking for what looked like the best fitting tip and trying in the socket before attaching it to the lead. This final step is where you have to take care. I needed a centre negative so using the end of the lead which has the word “tip” on it, you then have to match the negative with the negative symbol and away you go. It has to be the other way around for a centre positive. Once I had that worked out, plugged it in and away it went. The other important factor was that it delivers 2000ma which as it is driving a daisy chain for 8 guitar pedals it was important that there was enough power to drive them all. No problem there either. Versatile with lots of options.

Really handy
This is such a good charger as you can change the adaptor on the end to one of many different options depending on what you want to charge. So much easier than having lots of different chargers. The tips are easy to change and it charges things well.

One of the few that allow reverse polarity BUT be careful
I really like the option to have a universal charger that also allow me to reverse the polarity on the terminals but for sure I recommend anyone to be extra careful and always double check that everything is plugged in correctly before powering on.At a penny under £15 I feel that the price is fair.

Incompatible with LEXIBOOK CG1335 Chessman FX, Electronic Chess as underpowered.
Wanted to use for LEXIBOOK CG1335 Chessman FX, Electronic Chess but underpowered. Not a fault of the device, just would recommend ANY product that has an option to be powered from the mains electrical supply should advise on the mains adapter that can be used.

Good replacement power supply
Have been using with an old LCD screen that is really very old now, but still works for a standalone computer. This is a better unit than others I’ve owned, not least because of its options and safety features. It feels well made and comes with a good range of adapter tips which should suit most users.

Well-made and straightforward to use
I’ve got a few different mains adaptors (bought to run some photographic ring lights I bought a while ago) so I’m familiar with what to look for when buying them, having bought a poor quality one previously.One problem is that it’s difficult to work out the polarity of the power supplied at the connector. No such problems here, as the polarity is clearly marked on both power lead and the connector. If you want to reverse the polarity, simply reverse the connector. Helpfully, both sides of all almost connectors are clearly labelled, apart from the USB connector. With that connector, you have to ensure the triangle on the USB connector in on the same side as the triangle on the power lead. (My first picture shows the USB connector connected correctly and being used to power a USB ring light.)Another problem is loose connector tips which fall out if the lead is moved. Fortunately, the connector tips on this adaptor fit very securely and do not fall out with careless handling.Some power adaptors have a fairly modest power output, but this one has a healthy 30W peak output, and also helpfully includes a USB output on the base of the plug unit. When I unplugged the adaptor, the LED remained lit for about 14 seconds. Changing voltage is achieved by using the provided key (or a screwdriver) in the rotary switch on the back, and is performed with a very positive click. The power lead is about 145cm long.I tried this power adaptor with a few different electrical items, from Li-Ion battery chargers, to small desk fans, LED lights, etc. and whatever I tried it with, it worked without issue.That said, it’s a crowded market, and that reverse polarity may be a boon or a pain, depending on your needs and who’s using it. It might be that a “foolproof” power adaptor with a round connection to the adaptor tips (where it’s impossible to get the polarity wrong) may suit you better, so check out your options before purchase. For a jack of all trades adaptor though, this one doesn’t put a foot wrong.

Great AC adapter, easy to use, works with lots of things
Great AC adapter, easy to use, works with lots of things. The included key allows you to change the voltage, this making possible the use of this adapter with different items even thanks to the different pieces it comes with! Highly suggested

Good replacement power supply
I ordered this to replace the power supply for a device I had which had an EU plug instead of the standard UK. I needed a 5V 2A supply which this unit is capable of doing.The voltage is easily selected by turning the red dial using the tool included.There are many different device connectors to choose from so most devices should be covered included the device I used it on.I have had no issues with the supply and it appears to work well.

Great little power supply.
If the output of this meets your requirements, then I’d have no hesitation in recommending it.Comes with a useful selection of connectors, all of which fit tightly into the socket at the end of the lead, and all of which make good solid electrical connection.Some reviewers have found fault with the alleged potential to get the polarity wrong, but I would dispute any fault in manufacture. – All the connectors have the polarity clearly designated by it being moulded into the respective connector – so there should be no ambiguity about which way round the connecters are being used.Tests I’ve done show that the actual output voltages (on my particular unit) are all with 0.25 volt of that statedAll in all, a great little power supply for the price.

Versatile mains adapter with good output range and reversible polarity
This is a compact, quite powerful and versatile mains adapter at a sensible price that will provide 2 amps of output current throughout its range from 3 volts (where 2 amps = 6 watts) to 12 volts (where 2 amps = 24 watts).I bought this unit mainly for the reversible output polarity feature which consists of a decent length lead that terminates in a two-pin socket.What I liked:Nine of the more common sizes of DC barrel connectors are supplied, each of which ‘plugs into’ this in-line socket either way round.Output polarity (i.e. centre pin positive or negative) depends on which way round you insert the barrel connector onto the lead and polarity is marked on both the lead and plug-in connector: simply line up the arrowhead on the lead with the required polarity on the barrel connector and push the connector firmly home.The output voltage selector switch is quite stiff to turn, very positive and cannot be accidentally changed.The barrel connectors sit firmly in the socket and take some effort to remove, so they should not fall out inadvertently.Voltage regulation is very good: less than 0.05 volts drop from no load to half load – that’s pretty stable!A separate USB A female socket is provided on the base of the unit with a 5 volts 2amp output rating.The unit stays very cool in operation and barely warmed up in over an hour’s use on a warm day.The 5 Volt output from the built-in USB socket was almost right on the button at 5.06V: that’s very good!What I wasn’t so impressed with:The output voltages on the barrel connector were a tad high for my liking: nothing to worry about, but they were up to 10% high at the lower voltages. This is highly unlikely to cause any damage to connected equipment as a freshly-manufactured unused 1.5 volt alkaline battery can initially provide in excess of 1.6V. The output voltages on my unit are recorded below.Rated Actual3V 3.33V4.5V 4.71V5V 5.21V6V 6.18V7.5V 7.67V9V 9.06V12V 12.18VThe unit is double-insulated and does not have an earth connection (the earth pin is plastic, not metal), which results in a tiny amount of mains leakage current, but this is very low and I could only JUST detect it by rubbing the barrel connector across the inside of my wrist (it felt like a barely detectable nibbling sensation).Hint:If you find the range of barrel connectors included with the adapter is somewhat limited or does not contain the one you need, I extended the range by:1) purchasing this set of barrel connectors: Amazon part no. ASIN: B07F7776T62) connecting the 5.5×2.1mm barrel plug that came with the Soulbay mains adapter onto the two pin lead, selecting the required polarity.3) pushing the appropriate Aceyoon barrel connector for the equipment I was using onto the end of the 5.5 x2.1mm Soulbay barrel connector.A little bit of a christmas tree admitted, but it worked!Overall, versatile and not bad for the price, but the unit lost one star with me for the slightly high output voltages at the lower end of the range. This could just be that my unit wasn’t terribly well calibrated: you may fare better.

Warning !!! Tip markings on both sides of socket ? must look for tiny arrow for correct polarity
Item works as described but be careful when choosing your polarity make sure you use the side with the small arrow as both sides have “TIP” markings but they contradict each other..

Difficult to determine correct polarity
It’s easy to select the required voltage using the key supplied, but more difficult to ensure correct polarity.Studying the web site pictures, it would appear that the side with a small triangle at the base is the front. It is then easy to determine which way to connect the required adapter.If in doubt check with a volt meter.

Far less unsafe than some suggest when properly connected and set-up
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.
