Is it possible to tell if this power adapter will work with my canon a400?
It says, on it:
PLUG-IN CLASS 2 TRANSFORMER
"MW Switching Universal Power Supply", made in China, and a Canadian
Underwriters Lab Symbol
Model MWS1189UC
Input 100V-140V, AC 60Hz, 28W
Output: 3, 4.5, 6, 7.5, 9, 12v DC.
Current 1700 mA
-Does the fact that this adapter states a current at all, indicate that it
is 'Regulated'?
-Also, I have a voltmeter and I tested some NiMH batteries that were rated
at 1.2V
(much to my surprise, I had assumed they were 1.5V, but I got home and
looked at the package and it said 1.2V) right after I finished charging
them, and they were in fact, only putting out 1.2V when hooked up to the
large resistance associated with a voltmeter, when they were connected to an
actual load of much lower resistance, I'm sure their V would be even
less --- my point in all this being that even if my adapter is rated at
1700mAh, don't you think the camera could handle it anyway (especially if I
turned the LCD screen brightness way down) because it clearly can handle
batteries that put out significantly less than 1.5V? (sorry, long question)
-A lot of these NiMH batteries have ratings like 300mAh, or the highest I
think was 2300mAh --- does this kind of rating mean basicaly that for the
first hour of use, at the rated voltage of 1.5V, they put out that average
amount of current (because it would vary, wouldn't it, somewhat anyway as
the battery depleted itself)?
-If a NiMH battery was rated at 300mAh does that mean it puts out an average
of 300mA/hour at the rated voltage of 1.5V, over it's lifetime?
