I have a WEN Power Pro Model 9000 16HP generator. It has a female

funny-looking plug on the side labelled

DC 12V 8.3A



I have never known what this plug is for, nor can I find any info on

it in the manual or via Google. Some has said it is for charging the

generator batery. Could it be so?



If so, what wud the necessary plug/wire thingee be called so's I can

order same. I never saw one in the original box - now long gone.



Thanks

The manual I saw on line said it is NOT to be used to charge a battery. But

that is ALL it said.

Notice it says 12 V, not 12.6 V.



Yes, it does say that. But battery charging is about all it is good

for! The circuit on page 30 shows an AC winding connected to a bridge

rectifier, which provides 120 Hz DC pulses to the outlet.



I think the statement on Page 19 may be a typo or mis-translation.

Other similar generators have 12 Volt outlets specifically for charging

automotive batteries. The "DC plug with wires" shown on page 5, has

battery clamps.



If it's to be able to charge batteries, then it would have to be significantly
higher than 12V. An auto battery is about 25% charged at 12V, fully charged at 12.7, and chargers typically use 13.5 - 14V to do the charging. Which it may
be, it might just be labeled and spec'd incorrectly. If it's really 12V, it's
not going to work to charge an auto type battery. But it's definitely not
to charge the battery for the generator itself as the OP suggested. That's already taken care of by the generator.




The 12 Volt outlet may look like a 120 VAC outlet with prongs bent at an

angle to each other. That is what is on my Generac and Yamaha

generators. The plug is the same for the two, but DC polarity is

backwards.
