Belkin 140W ACAnywhere w/10A fuse

Guest
Hi,

I just purchased a Belkin 140W ACAnywhere adapter for my car. It
converts the 12V DC to 110V AC for use with a laptop computer,
cellphone charger, etc.

The manual says it will output a constant 140W. My car's cigarette
lighter has a 10A fuse. Therefore, I half expected that I would blow
the fuse when I turned the ACAnywhere on. But, it didn't blow the
fuse, and it worked normally on my laptop that probably does not pull
140W, but more in the range of 90-100W.

So, my question is will this wreak havoc on my electrical system?

Thanks

You'll know that you have a problem when you increase the load to the
extent that that 10A fuse blows, or smoke comes out of your laptop
computer.

What is the recommended procedure for putting the smoke back into the
laptop, so it will work again?

Soak the laptop in the toilet tank. Be sure to add 4 cups of concentrated
bleach and 1 cup of salt for every 1.3 gallons of water. Swirl. Flush.
Repeat.

No, it won't.

It is _capable_ of delivering up to 140 watts continuously, and would
probably draw 160 watts or so from the car while doing so, but will
only produce as much power as needed by whatever you plug into it (and
then will draw about 10% more from the car).

The AC Anywhere has a 3 pronged outlet like in the house that I plug
the laptop adapter into. So, if anything the laptop's adapter could
get fried. I don't see the laptop itself having any trouble.
 
These inverters are fairly efficient. It should be putting out 120 VAC. I
have no clue to why people refer the AC mains in North America to be 110
VAC. The standard from what we have been told is now 120 VAC, for many
years. I am sure if you measure the output of your inverter, it is going to
be 120 VAC. You will need a true RMS meter to see it accurately. If you were
to measure any of the AC outlets in your home they should read about 117 VAC
to about 123 VAC on the average. There are some areas where the voltages
would be a bit lower, but this is not the average.

The fuse in the car circuit will only blow if the load exceeds its 10 Amp
rating. If you are drawing 50 Watts of power at 120 VAC, this would be a
load of approximately 0.41 Amps at the 120 VAC level. I would believe that
the inverter would have maybe about a 10% overhead. This would be seen by
the source that is driving it.

Here is the clincher... At 12 Volts for the same given Wattage load, the
inverter will be pulling 10 times the current. This means that with a 50
Watt load, the 12 Volt side would be supplying to a load of about 4.1 Amps.
Then to compensate for deficiency loss, I would speculate to add another
10%. This should bring it up to about 4.5 Amps being pulled from the
automobile's cigarette lighter. If you were to double the load on the
inverter to 100 Watts, then the current pull would be about 9 Amps at the
cigarette lighter. I would guess this to be a safe limit from the fuse size
you indicated. If you were to put the full 140 Watt rated load on the
inverter, it would definitely blow a 10 Amp fuse in its input side.

No, car electrical systems are pretty crude and not all that fussy.

You've been living in a cave, haven't you? Or at least you haven't
popped the hood and looked inside the fuse box of a recent model
vehicle. I did the other day, and got just a little bit apprehensive.
See, it was a 2002 chevy tahoe, and there must've been at least thirty
fuses, not to mention at least a half dozen relays. In addition, each
of the 8 spark plugs has its own module. Gone are the days when vehicle
electrical systems were "crude and not all that fussy."

You'll know that you have a problem when you increase the load to the
extent that that 10A fuse blows, or smoke comes out of your laptop
computer.

----------------(from OED Mini-Dictionary)-----------------
PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.

Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).
----------------(For the Apostrophe challenged)----------------
