<DIV>I was having similar problems on Cellpro's with the power supply I was using (not Iota). Looking at the voltage input to the charger on an oscilloscope shows the load from the Cellpro's is far from steady and way too fast to see on a meter. Switching power supplies really prefer a steady load. I thought about capacitors and did some calculations, but at the currents we're drawing, they have to be very big. I tried some ones I had around (15,000 uF) and that helped, just a little. As John said, you really have to look at it on an o-scope to see if you're doing any good.<BR><BR>I ended up modifying the computer power supplies I'm using to put out higher voltage. That seems to be enough to keep the Cellpro's satisfied though I run them at less than full power.<BR></DIV>

<DIV>Chris,</DIV>
<DIV> If you have access to an oscilloscope by all means use it. You may not see everything with a DVM. A meter responds relatively slowly to voltage fluctuations as compared to an osilloscope. If the power supply is a switching type (I believe it is) the output may be "noisey" and that could be what's screwing up your chargers. Sometimes a capacitor across the power suppply outputs can help this but you need an oscilloscope to see what you're doing. :)</DIV>

<DIV>Went by HD at lunch. No luck. Doesn't look like they ever carried that model at the store where I went. Drats.</DIV>
<DIV> </DIV>
<DIV>I went online at the HD website and found this:</DIV>

<DIV><SPAN>http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100669124</SPAN></DIV>
<DIV> </DIV>
<DIV>Only 26lbs. Price includes shipping. I ordered one. I figure 750w AC should run my chargers and a fan. :-) I ran the battery in my van down once, it still started but the alternator quickly went out trying to charge a nearly dead battery. Don't want that to happen again. I have a 20 amp 12v power supply, but think I will get a 30 or 40 amp RV converter to go with this generator.</DIV>
<DIV> </DIV>
<DIV>I'll let you know how it turns out.</DIV>

<DIV id=EC_yiv1850378299>Well that would make sense--they speed up to produce power as it's needed--and a heating element is on and off to maintain an average temp. Certainly worth looking at. I like the little Honda as it's fairly easy on my wimpy back and quiet enough if you run an extension from having it at the front of the vehicle to the back--you are hardly aware it's there at full power. There's enough power to run two chargers and a small fan for motor cooling on hot days... I need to get a little oscillating fan--cool the motor--cool the pilot--cool the motor....<BR> <BR>BTW, I happened to be in the Muncie area touring some glass and fiberglass manufacturing facilities--(HOT)--but got a chance to stop by the AMA Headquarters after hours.

<DIV>One guy on the RV forum bought one at that price. The only complaint he had about it was the eco mode causing it to speed up and slow down constantly while his coffee maker was on. :-) I think it is worth looking at, and I plan to go down to HD today to see if they have one.</DIV>
