Decent Cigarette Lighter Plugs? WHERE??
 
Backgrounder: Where can one get a decent (i.e., robust)
general-purpose automotive cigarette lighter plug/tap? I have some
equipment which draws some amps at 12VDC. I'd like to install them in
my car on a temporary basis from time to time and use the cigarette
lighter receptacle as the power source. 2M mobile xcvrs being typical,
10 amps for a 50 watter, etc. One has a radio or whatever and one has
the specific power cable for the whatever. The problem (MY problem at
least) comes at the far end of the power cable, the widget, the plug
which connects the input end of the power cable to the volts and amps
inside the cigarette lighter receptacle. I've been to Radio Slack,
I've been to Pep Boys and I've been to HRO. The *CRAP* plugs RS and
Pep sell for this purpose are giggle-level JUNK. No surprise there of
course. As if I'll be able pull 10 amps thru the #26 wire they supply
with their plugs . . the HRO guy told me to try a hamfest. "Thanks Bob
but it's eight degrees F here, maybe I can find a warmer hamfest
tomorrow".

I have a borrowed example of a plug which should do the job in front
of me right now. The front end is typical, a spring-loaded centered
plunger for the plus side contact and two opposing leaf springs for
the ground side contacts, internal AGC fuse. At the aft end there two
nice big red/black screw-down terminal posts of the usual design which
can accomodate up to #10 wire, maybe even #8. Nicely finished, quality
piece. The only markings on it are a 5.9+mm patent number which has
been dinged and can't be read.

(A) Does anyone out there know where one can buy these?
(B) Or have a source for a similar alternative plug?
(c) Ignoring the fuse ratings how many amps can auotomotive cigarette
lighter receptacles supply before they become toast? What are the
standards/limits? Versus having to punch #8 wire thru the firewall and
do it right?

TNX a bunch, Brian W3RV

There's no single standard for all vehicles.

Your vehicle owner's manual should tell you how many amps your
particular cigarette lighter circuit will safely provide, and an extra
robust plug may exceed the capapabilities of that circuit, or exceed
the specs on the fuses for that circuit. The fuse specs should be in
the owner's manual, too, or you should be able to track the fuses down
yourself.

Most firewalls have one or more unused holes -- it's just a matter of
finding the grommit, and pulling it out.

Try a I know it will sound strange, but try a truckstop. Semi's have
all sorts of accessories that plug into cig lighter or accy. plugs, so
truckstops usually carry a good adapter and other items along that
line.

Not strange at all Keith. I borrowed the nice plug I described above
from an over-the-road trucker & ham buddy who picked it up at some
truck stop mobile electronics boutique. These guys really put their
lighter receptacles to work and they can't afford to mess around with
junk. But he drives 4,000 miles/week and at this point he has no idea
where he got it so I'm sort of stuck unless I go Interstate crawling.

Back to Google . . they gotta be out there.

Heh.

Brian,
Did you see the one at Radio Shack which looks very much like the one you
describe? The binding posts are not full size, but the construction is
above average. I bought one and think it is...well I'll say ok. It says 10
amps if I recall & If you believe it. It looked better than anything else I
saw and I thought would be ok for moderate loads up to, oh, I don't know 6-8
amps is my guess.

Also note that the newest "power connectors" that look like cig-lighter
recepticles have a rating posted right there. I don't remember what my van
says. I think (but don't hold me to it) mine says 180 watts total for both
of them (One in rear too) -- about 12 amps.

The real cig lighter can't supply much and I have had one go south with a 25
W mobile. It was dropping quite a bit of voltage causing a low rumble on
the FM TX so that it confused the repeater CTSS decoder. Took a while to
figure out--it "reparied" itself interestingly enough with no intervention
from me. I since went to the battery and more powerful rig.

Have you tried Digi-Key, Mouser, Newark, etc.?

Have you tried looking for an internet Truckstop? Surely someone, somewhere
has such a beast?

Finally, it never hurts to _call_ these places. Some will just brush you
off, but some may be willing to tell you about what they have, and keep you
from crawling all over the US interstate system looking for the right part.

Let us know what you find -- I'd like to know where to get these things,
too.

There's no single standard for all vehicles.

Your vehicle owner's manual should tell you how many amps your
particular cigarette lighter circuit will safely provide, and an extra
robust plug may exceed the capapabilities of that circuit, or exceed
the specs on the fuses for that circuit. The fuse specs should be in
the owner's manual, too, or you should be able to track the fuses down
yourself.

Most firewalls have one or more unused holes -- it's just a matter of
finding the grommit, and pulling it out.


I checked my own car last week and the circuit is fused for 15 amps. I
was just wondering if 15 amps is some sort of "standard".

I've done #8 zip cord thru firewalls installations but that's not a
consideration in this instance. I want to be able to occasionally move
my equipment from vehicle to vehicle without having to run a power
cable all the way to the battery. It's apparently done all the time
with a ten amp plug. Back to square one . .

I have one of the Radio Shack binding post plugs as well. It's in one of

Frankly, I think you'll also have to worry about the quality of the
cigarette lighter *plug* as well as the output capacity of the jack. As
you mentioned, the tip of these things is spring loaded. When you run a
LOT of amps thru it (the spring) it eventually looses its 'spring' and the
plug becomes unworkable. Remember all the current passes thru the spring
(almost like a fuse) no matter how heavy the actual connecting wire is.

I can't see why it should (the spring pass all the current), but even if it
does, can you not insulate either or both end of the spring so that it won't
conduct?

The spring is part of a serial path -- tip spring fuse
wire.

----| ////// [[[[[[[[ -----------------


Insulating the spring would leave you with an open path, just like
cutting the wire.

Frankly I doubt the spring-weakening idea. Some lighter
adapters are just poorly made. I've had some fail to make decent
contact when brand new. I've often had to twist the adapter around
until it made good contact.

I also bought a 110V to 12V (lighter scket) adapter and had
the same problem as in the car. I originally got it to avoid battery
failure problems while uploading firmware to my GPS unit. It still
required a little twisting to make good contact. Same when I later
used it in my office to charge a cellphone.

I have no idea what exactly makes this kind of connector
unreliable, but I've never yet found one that didn't cut out
intermittently.

: describe? The binding posts are not full size, but the construction is
: above average.
(snip)

I have one of the Radio Shack binding post plugs as well. It's in one of
my 'go kits' for emergency use.

Frankly, I think you'll also have to worry about the quality of the
cigarette lighter *plug* as well as the output capacity of the jack. As
you mentioned, the tip of these things is spring loaded. When you run a
LOT of amps thru it (the spring) it eventually looses its 'spring' and the
plug becomes unworkable. Remember all the current passes thru the spring
(almost like a fuse) no matter how heavy the actual connecting wire is.

Richard in Boston, MA, USA

I can't see why it should (the spring pass all the current), but even if it
does, can you not insulate either or both end of the spring so that it won't
conduct?


The spring is part of a serial path -- tip spring fuse
wire.

----| ////// [[[[[[[[ -----------------


Insulating the spring would leave you with an open path, just like
cutting the wire.

Frankly I doubt the spring-weakening idea. Some lighter
adapters are just poorly made. I've had some fail to make decent
contact when brand new. I've often had to twist the adapter around
until it made good contact.

I also bought a 110V to 12V (lighter scket) adapter and had
the same problem as in the car. I originally got it to avoid battery
failure problems while uploading firmware to my GPS unit. It still
required a little twisting to make good contact. Same when I later
used it in my office to charge a cellphone.

I have no idea what exactly makes this kind of connector
unreliable, but I've never yet found one that didn't cut out
intermittently.

I've done #8 zip cord thru firewalls installations but that's not a
consideration in this instance. I want to be able to occasionally move
my equipment from vehicle to vehicle without having to run a power
cable all the way to the battery. It's apparently done all the time
with a ten amp plug. Back to square one . .


VW seems to use a 20 amp fuse for the lighter -- at least in the Jetta.

The problem seems to be voltage drop -- perhaps they can handle 20
amps, but there is still voltage drop -- even 10 amps had a good deal
of voltage drop.

Radio Shack sells an adapter that would work. It's rated at 10 amps and comes
with a pos and neg binding post, like that on a power supply. With a decent car
ACCESSORY port (not cigarette lighter port), you can run a 50 watt FM radio. I
have been using on in my work car with no problems. The radio indicated over
14VDC when it is turned on and plugged into the aftermarket accessory port.

At the aft end there two
nice big red/black screw-down terminal posts of the usual design which
can accomodate up to #10 wire, maybe even #8. Nicely finished, quality
piece


That sounds like the one I picked up from Radio Shack. Part number 270-1521.

First I've heard of an "accessory port" vs. a lighter rerceptacle. Do
you know if those are available as aftermarket items which can be
installed separately from the usual lighter receptacle?

That's it! That's the plug I borrowed from my buddy. So he didn't get

My '99 Dodge PU has one, plus a lighter jack. They look similar but the
accessory jack is fused higher and, unike the "lighter", isn't on the
ignition switch circuit. Works great to power different 50W 2 meter and
dual-band rigs. There's also a place in the armrest for your packet station

I use an FT-3000 in the work vehicle, and it displays the voltage when first
turned on. With the cig lighter, it shows around 12v. In the aftermarket
accessory port, it shows over 14v.

Yes. Try www.galls.com.

And a good thing about the Radio Shack website is now you can look up an item,
type in your zip code, and it'll tell you if that item is in stock in any of
your local Radio Shacks! :)

Backgrounder: Where can one get a decent (i.e., robust)
TNX a bunch, Brian W3RV


I've given up on cigarette lighter plugs and am converting all of my 12V
stuff to Anderson PowerPoles. Just yesterday I've bought a car charger
and one of those portable auxiliary starter batteries and the first
thing I've done to them was adding a set of PowerPoles. In my car I have
them also as my HAM power supply in the shack.
