12v 2a Power Supply Adapter by Keple | 2Amp AC DC Adaptor Mains Plug for Home Appliances | CCTV Camera, Yamaha Keyboard, Router, Hub, Switch, LED Strips | 2.1mm 5.5mm Barrel Jack Connector

Bought this to power an electronics project 3.3/5V supply unit - worked fine, doesn't get hot/warm - not really much else I can add other than has a good selection of plugs which will probably come in handy at some point.

I bought this to replace the Yamaha PA150A 12v 1500mA supply which runs my Yamaha Moxf8, and which suddenly stopped functioning after two and a half years. It works fine, there are no unexpected noises on the audio outputs of the keyboard and the attached connector fits well. Plus it costs about a quarter of the price of a replacement Yamaha supply.

It's seems nearly impossible to buy an AC adapter suitable for the HTC Vive link box. This really is absurd because you can buy a spare link box directly from HTC but not the corresponding AC adapter to go with it! This wouldn't normally be a problem but HTC chose to use a very unusual size of DC jack for this device and as a result it rules out 1000's of AC adapters with standard sized plugs in the process.I actually took a bit of a risk with this Keple 12V 2A AC adapter... it had the correct voltage at 12V DC, current at 2 Amps and one of the supplied converters that comes with it looked like it will fit the HTC Vive link box, so, decided I should give it a go.I was happy to discover that one of the converters (marked 'H' with a red plastic coloured ring on it) fits into the HTC Vive link box fine. You then connect the Keple AC adapter's lead into the back of the converter plug. Unfortunately the lead coming from the Keple AC adapter has a right-angle plug on it which makes the connectivity to the HTC Vive link box a bit untidy but it does fit (see attached image). I would have preferred a straight-through connection from the AC adapter but with such limited options available I'm not going to complain!Before powering up I also checked the polarity was correct. As advertised, this was centre pin is positive. Unlike other AC adapters with multiple fittings you cannot change the voltage or polarity of this AC adapter which limits its flexibility for use with some other products.This AC adapter from Keple works perfectly for my rather niche requirements and as a result I'm very happyPros:- Provides 12V @ 2A DC- Various converters/adapters supplied for connecting to multiple devices (centre pin is positive)- Feels well made- 2m cableCons:- Polarity cannot be changed (not without butchering the cable and voiding the warranty!)- The plug from the AC adapter has a right-angle connector on it which limits the cable tidying capability

Bought as a replacement for a lost light pad cable. Beware if you're buying to replace a cable where there is a small gap in your appliance for the power supply, as the jack adaptor is quite bulky.Nevertheless my light pad seems to work just fine but the cable isn't as secure as I would like and it's easy dislodge.

This little multi tasker literally saved my laptops life! After my dearest adolescent son managed to lose my charger I was stuck! Then this little beauty came to my rescue! It's value for money and as it came with loads of other Jack's, it will be useful for other electrical items!Brilliant all rounder!

Didn’t work for me but to be fare could be the DVD player who knows ???

I needed a replacement power adapter for my router. This item stated it was universal & fit any hub. Well, it didn’t. It didn’t even come close. It’s totally miss advertised.

Great little quality power adapter, runs my Reolink PTZ camera nicely with very little heat dissipation. Much better than the 30W POE injector i tested. well made and the device appears to have legitimate CE marks for once (apparantly designed in London made in China so it said on my box).
