Question: I understand that an AC adapter is needed for the viewer.  Where can I purchase an adapter that fits this viewer?
Document: Delivered on time. Viewer works as described. Battery life is long due to the LED's. Wish the AC adapter came with it.
Works great with slides. Negatives are fairly easy too, but some get curled and are sometimes hard to feed. A more pricey model would be good with a negative holder that inserts into the unit. Overall it is a good product. Where do you find an AC/Adapter for this model. The box it came in states an adapter can be purchased separately. Where?
While the negative viewer (the side slit) is better than trying to hold the strips up to the light, keep in mind that all you are getting is a magnification of the negative. You will only see dark and light shades, not color. However I find that it helps me identify what the picture is about before I scan it.About the only negative (and thus the reason for 4 stars versus 5) is that no AC adaptor is included with this model.
It is not easy to find good quality AC adaptors and they are not cheap. If you go looking for one, take the viewer with you since adaptors come with a variety of types of tips and you want to make sure that it works for your model. There are adaptors that are called &#34;universal&#34; that come with multiple tips that are good choices assuming one fits your viewer.
Extremely useful for sorting slides. Before receiving it, I borrowed a light board. The magnification feature of the viewer increases the usefulness of the light board.
However, it tends to jam when the release button is pressed to clear the slide from the viewer. I cannot in all fairness blame the viewer for all the jams, because my slides are old and some may have slightly swelled edges. But some are pristine, and they still sometimes jam. I found that I had to use a pair of tweezers, while holding down the release button, to clear the slide.
Had a viewer many years ago, and I  remember it as working smoothly, without a hitch. Although it too was a manually operated viewer, it had the capability of holding a small pile of slides in a side tray and pushing them through one at a time, with the next slide pushing out the previous slide into a  holding tray. This view must be fed one slide at a time into a slot at the top. Then it drops down into the viewer.
Easy to use. Like the large display. Good quality. Highly recommend. I use it to review old 35 mm slides that I want to send out for digitizing.
Very poor images on viewer and slides stick in viewer
It works better than expected. slides are clearly displayed and the viewer holds more than one slide in the holder.
Answer: I do not know WHERE you can find an AC adapter but the viewer doesn't NEED it as it works great with batteries which is how I use mine.
