Rated 4 out of 5 by from Solid little adapter with minor issuesThese are typical of many small "wall warts" in that they don't regulate well until you have some load on them. My application for this was to replace the batteries is a small decorative LED string. Open circuit, the voltage was ~6 volts, lightly loaded with the string of LED's it's ~5.2V. If the regulated voltage is important to you with very light loads, you could use a shunt resistor to add enough load to get the unit into regulation, or spend more money on another adapter with better regulation. But, for the price (and most applications) they are just fine.

Rated 5 out of 5 by from perfect ac adapter for eton G8 radioThe 6vdc adapter which was designed for the G8 radio didn't work- produced an AC buzz. The 4.5vdc adapter was a perfect match and the radio works great. Hope to place another order with parts express in the future.

I have a 4.5 volt 100 mv that I cannot find .what is equivelent to it this is output

Asked by: james12345
Is it 100mv or mA? If it is mA than any 4.5 volt adapter with 100 mA rating or higher will work as a replacement.

I have an old SONY Portable CD Player D-EJ109 (Purchased in 2005 but still works well) but I never had an AC Adapter. Description says the requirement is for DC IN 4.5 V (external power input) jack. Will this product work with my device?

Asked by: SlipperCity
Yes this will work in terms of voltage although I do not know which size plug you will need for the CD player.
