Zolt 34W Universal Power Adapter 3V 4.5V 5V 6V 7.5V 9V 12V 2A Max

The charger unit looks very well made and displays a green light when switched on. This light doesn’t go out right away when the unit is disconnected from the mains but decays slowly.It is important that you check how the socket on the item you want to charge is configured is it + or - on the centre pin. This can be found on the charger unit you are replacing , an adapter lead is available.The voltage required can be set on the charger unit and a tool is supplied to alter this.Additionally there is USB A socket hiding under the bottom of the unitThe next step is to choose the correct connector to fit the item you want to charge, a good selection is supplied.The only danger with this charger is if you use it to charge several different items which have different voltage requirements. If you forget to change the voltage setting you could damage the item you are connecting, by supplying too high a voltage.This charger is a great unit but you need to use it with care.

Works for me, although I was wanting 30w output from the adapter (non USB). I should have read a little bit better.The total output is 34w.Setting this to 12v for the adapter (non USB) at 2amps will give 24 Watt output (which is working for my device although 6 watts less).The USB port outputs a max of 10 Watts (which I probably won't ever use).Which goes up to a max total of 34 Watts.The max output is good enough for my device, although under powered slight working great. Would recommend this.

Smashing product with lots of additional connector tips and a very useful switch key. Having read the item description, I realised that I needed a polarity converter so I ordered that also. It didn't seem to work until I realised that I had to choose the corresponding voltage on the plug by using the switch key. It now works perfectly! This is an excellent product but electricity is dangerous and complicated. Read all the help carefully!

I love these things, they cost what a specific charger costs but are flexible enough to charge almost anything. This one ended up replacing a 5v charger when i had to use a long extension cord and the voltage drop was just a little too much for the device on the other end. So i cranked this to 6v and swapped them out. I've bought a bunch of these, this one is on all the time in a warm cupboard and has yet to die months later.

It worked in my case without having to use any of the spare connectors. A versatile switchable voltage power supply with a wide choice of adapters to fit almost anything

The adaptor looked sturdy and appeared to be what I wanted. The plug end used fitted my Roberts Expression dab radio, but when fitted to the cable was not a firm connection. I used just the plug end on the cable and this fitted well. Unfortunately when the unit was switched on the radio had a horrible buzz and distortion. I left the radio in situ and switched off the adaptor. The radio worked clearly. I did this a bomber of times with same result. The interference did not clear with time. The best thing I could say about the unit is that it does charge the batteries. I have returned the unit and hope to get one that charges and supplies power to the radio without causing the sound quality to down grade.

I couldn't find a charger for my cordless Dremel and found this. Works fine.The only thing I don't like is that the good selection of plugs it comes with are loose so easy to lose

Looks so promising and incredibly useful but unfortunately none of the bits fit and it doesn’t charge the tools I needed it for.

Good
