Can it be used all day, every day at the office (8-10hrs/day x 5 days/wk)? Can it be plugged into a 110V USB wall plug adapter?

The one I purchased could only be plugged into a USB port for power. As to leaving it all all day, I would say that I've only had mine on for a few hours a night because even though the lightning bolts can be seen during the day they are more dramatic in a darkened room. It is well made, so I see no reason it couldn't be left on all day. Hope this answers your question.

I have used mine in the office every single day for over 4 months and nothing has gone wrong yet. I do not know about the wall plug and everyday use because mine is plugged directly in the usb port of my pc.

I have had it on 24/7 for about 3 months now and it's going strong. Yes you can plug it into a wall adapter

Yes, it can be plugged into a 110 volt wall outlet and works as advertised!

Yes, you can use pop-out USB connection to charge it or even use a USB wall adapter (like for a cell phone) to charge it. I have used mine for 20 minute interviews and never have had it go down a "bar" in battery life. I always charge mine for the equal amount of time I used it for and it works out well that way.

You *can* keep it plugged in, but it's not good for the battery. It's better to charge it, then let it run on battery. It warns you about 9 days before the battery goes (when you go to take your temp in the morning, you get a "BA09"... the next day "BA08" etc. But it still functions on those days. I think I charge mine overnight about once a month? So, you COULD leave it plugged in, and it would still function, but my understanding is that you'll reduce the longevity of the machine. (When you need to rely on the battery, the battery life might be compromised.)

if you have a standard wall outlet to usb charger adapter: yes it can be used while charging or 1.5-2 hr battery life

I purchased one and it has worked perfectly, being used about 1 hour per day. No idea why yours might not be.

The power source has to be plugged into a wall outlet. You could possible retro fight a USB adapter if you know how...

Yes it can be used plugged in. Also it can be used without being plugged in.

You can plug a regular usb into it, and it comes with a micro usb cable attached. It should work universally as usb output is only 5v

I've mostly used it on USB, but from time to time it comes unplugged and I dont notice til days later that it's still running. I've never attempted to use it for 80 continuous hours, but I'd say it lives atleast 60 before it needs a charge.

The device itself runs on 5VDC at <2a using a standard micro USB connector. I gave up on finding the adapters for the wall wart and threw it out (one less power supply to carry as well).

Not really it's going to be a waste of energy . I plugged it 2 hours before using it.

I charge mine from either the car adapter or a wall wart in the office. Use a quality one, like an iPhone USB charger. No issues with mine.

I do not think so. The USB adapter is for transferring data only. Only DC battery. no 110 AC input.
