SoulBay Universal 30W 3V 4.5V 5V 6V 7.5V 9V 12V AC/DC Adapter Switching Power Supply Charger PSU with 8 Selectable Adaptor Tips for 3V-12V Household Electronics and LED Strip - 2000mA Max

I ordered these to replace a similar item that did the same task of transforming mains supply into lesser voltage values. This is designed to provide a range of voltages for items e.g. Portable DAB radio that uses 6 volts via 4 Size C batteries, which of course run out in your favourite program.This avoids that problem so you have a permanent mains supply, no more missed radio programs.This voltage converter not only has varying levels of power, but has a range of assorted fittings that fit varying electrical items, you select the adapter that suits your equipment, connect it to the lead that supplies the power via the adapter, check and change to yhe correct voltage and you get the same power supply that suits your item.A very versatile, well made power supply (adjustable) with real quality adapters.Stable power output and works well connecting via a standard 3 pin plug (UK Type G) and has a voltage output adjusting key.Excellent item. Recommended.

This plug with its various sizes of adaptor holes turned out really well for me. Has the option (with a key provided) to turn the device to the correct voltage.

I particularly like the fitting which allows bare wires to be attached! Very versatile!

Works for particular job of charging a battery where the original charger missing.

Perfect and versatile

Great service, delivered ahead of due date. Worked well to replace a broken unit for our exercise bike

Works fine, item as described

Didn't work on what I needed it to
