## Questions & Answers

**Q: how does everyone say this is the right adapter?..my FR-300 has the middle pin negative...this charger looks like it is reversed..**
A: I have two Eton Model FR-300 radios and this adapter works just fine. I have used this for many months. I cannot speak for any other models. I would ask Eton directly.

**Q: just want to know where I can get a cell phone charger adapter for a Eton 300?**
A: I suggest trying Wilson Eledtronics--they have almost everything for radios including cell phone connectors.

**Q: can anyone verify that that this is the right fr300 Eton adapter with a middle negative pin?**
A: Apologies, I really dont remember.
bcook@mcn.org

**Q: I just got this and it is 5V @ 1A. The radio's manual state the charger should be 4.5V @ 200ma or the battery will be damaged. What's your experience?**
A: The original ETON Adapter Part Number GPU3504 was:
4.5 volts with the center pin being negative 
with a maximum current of 100 milliamps (0.1 amps).
The 3.6 volt battery pack is three 1.2 volt Nickel-Metal-Hydride batteries in series.
Nickel-Metal-Hydride batteries are very sensitive to being charged.
The charging voltage for each cell must be between 1.2 and 1.6 volts.
Therefore the maximum charging voltage for the battery pack is 4.8 volts.
The manual says;
IMPORTANT NOTE: If using an AC adapter rated higher than 
200 milliamps, unplug the internal rechargeable battery to avoid damaging it.
Later manuals had a Notice that the embossed 5 volts
on the radio was wrong and should have been 4.5 volts!
