Cool.

a) seems unlikely but it's under warranty so that's the first step
b) the inverter has two 110 outlets and I was using just one.. with an air pump which would impose a consistent power drain so if there was a problem with it, it should have shown up right away
c) a possibility I suppose - however this is a pretty nice charger.. it should be overkill, actually
d) na, too simple even for me to screw up :)

Thanks for the input, Sleepe

If this is the last post, it was probably the battery!

Just curious what's the operational amps of your 110v inverter and what's the operational amps of your load (air pump)?

The intervert reads: 112W pump. 58A Max

also:
inverter
115v at 500w = 4.35 Amps

air pump
112w 110v = 1.02 Amp

Does that look right?
