Comparing *Small* Inverter Generators

When I use the Earthquake generator to charge a pair of T105s at about 50% SOC, I have to initially force the PD converter into its 13.2 volt mode. After 10 minutes or so I can step it up to 13.6, and sometime later to 14.4. I have to keep the current at 35 amps or less, which equates to about 900 VA with the PD converter operating in boost mode. I also have available a worst-case fallback of being able to fire up the built-in Onan for the initial charge. I find it ironic that after changing the long #6 wire between the converter and battery to a short #2, I realize that having the long wire to limit the current could occasionally be useful.
