Actually, what I was thinking of was the Echo Charge from Xantrex.
But I got the company wrong The DuoCharge seems to be a similar
device as well. Both copies of the Eliminator which has been around
for years before both of the others.

I believe the DuoCharge is pretty much a knockoff of Eliminator,
functionally. I wanted an Eliminator for a long time, but choked at
the cost. The DuoCharge came along at a better price point, so I
jumped at it.

The Xantrex is really a different beast, though the difference is
subtle. It follows the input voltage profile, whereas the DuoCharge
is effectively a single stage charger powered off the house bank
instead of 110v. If your starter and house banks are the same type,
the Xantrex will likely do a better job of keeping the starter bank
charged if it gets discharged more than starter banks normally do. It
does not work as well if batteries with significantly charging voltage
requirements are used. The DuoCharge allows for batteries of
different types, but the output curve is basically similar to an
automotive regulator.
