A person dpes not need a small power supply with a small generator. Period. But all of the power supplies have fragile hypersensitive trimmer pots that defy easy use. Why they do not fit a 69 cent 10-turn cermet I do not know. But disassembling the power supply to solder in an alternative is not for everyone. Me included. But it has to be done. I purchased caliper dials to fit the 500 ohm Vishay pots so I can dial-in a voltage by numbers. The Borg has a pair. My latest quest is 4-1/2 digit voltmeter and ammeter with 1.1" LED segments. Lools like the 5-amp float will be 13.2 volts fixed.
The 90-amps potential is enough to satisfy any portable responsibility.
Landy sure found out about parchment thin starter battery plates and thermal gain.
With caliper dial and chart the power supplies become very user friendly. Yes mine has an Intermatic 7-hour spring wound timer. I can play this thing any way I want up to 6-hours then the float kicks in. The float is plenty to sustain my BiPAP.
Now I need someone who does electronic repairs to solder in the pots.
