## Customer Reviews

### ⭐⭐⭐⭐⭐ Works Like A Charm!
*by G***E on June 9, 2017*

This is an excellent little 12 VDC to 9 VDC converter and works exactly as it's advertised. I am using it for camping and instead of buying lots of D-cell batteries I use this to power my 9 volt camping fan and light which normally requires 6 D-cell batteries. I can now use this little converter to run off my rechargeable AGM 12V batteries which last much longer on a charge plus power my many 12v needs during the day. I checked the 9v output of this converter and it was 9.19 volts with no load and 9.09 volts with a 0.55 amp draw. The MFR claims 96% efficiency and I believe that is quite accurate. After running this converter for an extended period of time under load it remained very cool. It's about the size of a small box of Diamond matches, so takes up very little space. It has ears on both ends for permanent mounting, and it appears to be well sealed in case of moisture. Use connectors that prevent the possibility of getting the polarities backwards, and you should be in good shape for years to come.

### ⭐⭐⭐⭐⭐ Worked great to power two a Motorola Talkabout Charger base station
*by A***M on February 23, 2024*

Does its job as requested. I connected this to a cigarette / aux plug on one end, and the other to a barrell connector to plug into a Motorola Talkabout charger. The goal was to keep two radios charged in their base station. Goal completed.Delivers 9v as promised and plenty of length on the wire leads to do what I wanted.

### ⭐⭐⭐⭐⭐ DC converter works great in my travel trailer!
*by C***K on November 18, 2020*

I purchased the Magnolian 12V to 9V DC converter so I can run a 9V Sony AM/FM/CD boom box radio in my travel trailer, running off the trailer’s 12V battery bank when we dry camp instead of depending on 6 C batteries. I soldered a 12 volt dash cigarette lighter male plug to the “line in” wires and the “line out” 9V wires to the battery connections in the boom box. This way, I can run the radio on DC or use the AC plug included with the Sony to power my radio whenever we have a full hookup. So easy, even a caveman could do it! I’m very pleased with how this set-up works in my trailer. A perfect solution to the problem of C batteries running dead all the time. Of course the trailer’s 12 V battery bank recharges every time we move to our next campsite.
