WOW that IOTA is a deal. I grabbed 1 to replace my WFCO junk. 30A is all I need.

The IQ4 upgrade is $20 on Amazon

Thanks for sharing


There was an Iota about 12 years ago ( ISTR it was in Jaycos) that did not have the jack hole (whatever that is called) for the IQ4 (which used/uses the same jack hole for the booster jack they had.)

So be sure this one has the place to plug in the jack if you want an IQ4 to go with it. They have a new range of IQ4s now, for different charging profiles you can choose from.


Data sheet for this model HERE says it has the jack..

From the data sheet..

"Dual Voltage jack allows for manual selection
between Normal and Absorption Phase
charging as well as easy installation of the
IQ4 Smart Charge Controller

Can be used with the optional IQ Smart Charge
Controller for automatic multi-stage charging to
prevent battery sulfation and stratification"


And directly from Goldmines own page..

"Note: This unit is not a smart charger without the purchase of an optional IQ-4 Smart Controllers."

So, from everything I can tell, it will accept the IQ-4..

Although you are welcome to contact the vendor to confirm before ordering..

Actually was considering buying one myself, would make a real nice power supply for my Ham equipment plus the bonus of multi stage charging if I add a battery for backup purposes.. Dedicated 30A 12V power supplies do not come cheap..

Sorry I hijacked your thread iski4fun.

Do yourself a favor and buy one of these IOTAs. You can't beat the price, and I believe you will need one. If you're not comfortable putting a 120V plug on it, find someone that can.

Even without the IQ4 controller, it's better than what you have. My WFCO converter puts out a constant 13.6V and I've lived with it for 7 years. You just have to be careful to not let it boil your battery.

I believe IOTA floats close to 13.7 so it might be a bit high for camping in the heat.

I received my IOTA today. It measures 13.52V on my calibrated Fluke. It's advertised as 13.4V on the enclosure label.
I'll order the IQ4 tonight

Thanks again for bringing this to my attention. I'm always looking for a deal.

On Edit: I realized this morning the 13.52V I measured last night was at the battery. The voltage this morning at the IOTA output is 13.60V and 13.58 at the battery.

Found it - beneath the oven! Thank you all for the info and direction. I had to remove CO2 detector to get eyes on it. Looks like I'll be removing the oven and some drawers. It make much more sense now - thanks again and Happy Holidays everyone!

Glad to be of some help.

Check to see if your converter has some fuses blown on it, they often include reverse polarity protection fuses which are supposed to blow when the battery is connected backwards..

Might be a low cost repair in that case.

If the converter is dead, that IOTA 30A converter is still available at Electronic Goldmine surplus for $40.. You would also need to get the IQ-4 smart plug to get multistage charging (recommended), I believe that is going for around $20.

My preference for replacement is Progressive Dynamics wizard models but the IOTA with IQ4... A very very very very tight #2 on my list.
How close are they? Bumper locked. is the term that applies.

I replaced my **** Magnatek with a Progressive Dynamics from Best Convertors. Talk to Randy there.

As time2roll pointed out, the IOTA floats at 13.6V, same as my WFCO. A bit too high for camping in the heat. This boils my batteries over time.

With the IQ4, the IOTA bulks at 14.8V, absorbs at 14.2V and floats at 13.6V. It's my understanding this profile is too high for my Johnson Controls 29DC batteries. iski4fun`s batteries may better handle these higher voltages long term.

My $70 IOTA with IQ4 will make a nice multi stage bench charger/power supply but I'm not replacing the WFCO with it.
