Harbor Freight Predator 3500W question

Champion on sale

Same price on Amazon too.

What 12 volt DC device are you charging via a 12 volt DC source?
With genset running you can use any standard 120 volt AC charging device.

Thanks everyone!

I think I'll cross off the Predator 3500 as I'd still like to have the option to charge electronics using the 12 volt socket if necessary.

My power house 2100 manual says you can back charge the generator battery with that 2 pin plug. If you leave the remote start on the battery will go dead in a few days. If you use that 2 pin to hooked to the TT battery that won't happen.

It's for the 12v banana plug wires, for recharging a battery.
They are the LAST thing to use use, as they are very inefficient. You're better off using jumper cables instead.

How to recharge battery without shore power
1. Plug the shore cord into the generator and let the converter charge.
2. Use a separate stand-alone charger.
3. Use solar power.
4. Use the jumper cables and connect trailer battery to vehicle battery.

Last choice, the generators 12v connection.

What practical use does a 2-pin (12v) outlet have for camping purposes?

They are supposed to be for battery charging, but I've never used it nor do I know anyone who has. They are unregulated and low amperage, and on my Honda only work at full throttle.

The owner's manual should supply any further information.

A tad off topic. I bought a Champion 3100 w remote start online at Walmart this week for $650 delivered. It also happens to be Hurricane prep Tax free week in Fl so no sales tax.
