Customer Review: Works..but you have to know what you are doing!It's very unforgiving!
Summary: 2 Stars

After receiving item, I found it did not have a 2.5mm sub mini jack. I used a R*Shack Adapterplug "E" plug. The unit works as advertised. There is a temperature concern (120 degrees F) but not unusual since this transformer can deliver up to 1 amp. If you need only a few milliamps then go for an adapter with 300ma. Because of the heat, it's not for home use and needs to be isolated from flammable materials. I kept it on a power strip and kept the air vents clear. Heard that some blew up and that WILL happen if you are using the transformer to charge a battery built into the device and using a lower setting than the battery voltage. The battery having a higher voltage will send the extra voltage back to the adapter; overloading it. It is VERY important to match the voltage to the device. Some say that they put a volt meter on it and the voltage was higher than expected. That's because the unit is using a voltage regulator and needs active current to flow in order for the regulator to adjust the voltage to an acceptable level. I'm a technician with electronics background and not a complete expert by any means. That would require a Masters or PHD.

Bottom Line: This transformer (made in China) with no UL label can provide you the power you need for your equipment but due to it's lack of safety features and it's high heat dissipation should only be used by someone that knows electronics and more importantly voltages and current demands of their unit. This unit is unforgiving if you select the wrong voltage settings. It will smoke and cause fire.
