Round Jack Plugs

[rotrax]

Hi, I know some on here are electrical whiz kids and are familiar with parts.

I need to run a remote charging lead for my Bluetti 180 Power Station. The supplied lead is barely 60cm long, I need 6-7 metres.

The supplied lead has a conventional looking round DC Jack Plug, but for an 8mm socket. I can only find 5,5mm ones. It needs to be rated for a max of 10 Amps.

Anyone have a source?

TIA. If I cant find one, I can, of course extend the old one, but would prefer not too.

Is it 7.9mm rather than 8mm - that seems to be a size that does exist...

Could it be a Hella or Bulgin type, or something like that?

You need to check the inner pin diameter. If suitable Farnell have it.

It's also known as a DC7909 plug by Chinese suppliers.

I had the same issue when using the power ports on my Jackery power bank - they put sockets on that require plugs that are hard to find.

I think confusion is arising because Rotax in mistaken in thinking it's a jack plug.

I suspect what he's after is a DC7909 plug on an extension lead with a DC7909 socket on the other end.

Commonly mistakenly called jack plugs. Proper name is barrel connector.

That looks like 2 of those will be a cheaper easier solution than my Lumberg plug and making a custom cable as Farnell are expensive and the cable will need to be bought as well.

No. This is a barrel connector.

Ah... that would be a cask connector, not to be confused with a keg connector

Thank you-that might well be the answer. I will need two, as the power station will be some distance from the most suitable charging source.

Appeciate all the help-this really is a useful forum!

How about cutting the lead and splicing in a longer new one, preserving the original connector?

That was the option could I not find anything suitable.

Thanks to Little Sister, post #6, It looks like I can get the ends and length I need.

Thanks guys-now I know they what they are called, thanks to the forum, thins will be easier in future.

For those here with long memories, I think that's a Lakesailoring.
