1ST field monitor purchase. WTF, No power cable
Aug 23, 2022 18:17:49 #
Just received a Neewer F100 7-inch monitor (Amazon was selling them yesterday,for one day at $90.) So I pulled the trigger. I want to use it indoors for macro photography. For some reason, they do not come with a DC 12v power supply adapter. It says to use a 1.5A adapter. I have a 1A power supply adapter with the correct 5.5mm x 2.1mm male end and was wondering if I'll be OK using what I have or should I go ahead and buy a 1.5A adapter?

I'd buy the 1.5A adapter if that what the monitor requires (states).
The actual requirement may be something like 1.2A, which the 1.0 will not be able to provide,
plus, the 1.0 will probably run hot, shortening its life.
(Better to use a 1.5A for a 1.0A requirement, than under powered.)

They still make them?

The B&H listing for this model says the monitor operates off of Sony L Style batteries, these batteries are not included, neither is the A/C power supply. In the Q&A on the product, a "Neewer Rep" responded saying any 12V AC power adapter can be used, none are included in the purchase. This sounds like a product straight from Abe's ....

CC, As it turns out, seems like ANY field monitor under the cost of $200 just doesn't include power cables.

Perhaps being the field monitors they are meant to run on variety of power option which they leave it to the user to choose.

I get it. I guess what I'm asking is, using an
adapter rated at half an amp lower than the recommended amperage will it potentially cause harm to my equipment? Any electricians out there?

I suppose my post wasn't what you wanted to hear.
I'm only an electronics engineer, not an electrician.
Addendum: If the power supply cannot provide the rated power,
the supplied voltage may be lower than required, which may affect the operation of the device.
The voltage regulator circuitry would try to supply the required power, and if it can't, it will overheat,
shortening the life of the power supply.
Try this: current required in amps = rated power in watts (of the monitor) divided by voltage supplied in volts (12).
If your answer is less than 1.0, it will probably work.
Your 1 Amp, 12 volt supply can supply 12 watts at the most. Power (watts) = voltage (volts) x current (amps)

You can try your unit but it will probably overheat or shut down.

The monitor needs 50% more power than your 1A converter’s rating.
Your 1 A converter could “brownout” and that might damage the monitor circuitry but more likely your 1 A converter will simply overheat or shutdown.
Personally I wouldn’t do it I would get the recommended converter.
