How often do you need to charge it and how do you know when it is fully charged And how many hours does it hold a charge when in use?

It holds the charge very long, I charge it once a week with 4 hours recording 4-5 days/week. There is a steady light indicator to show fully charged level.

It blinks red when charging, and stays red when charged. Haven't run it for long periods, but instructions indicates that it will go 13 hours.

When you start to charge it a small red LED on it starts to blink. When it is fully charged it stops blinking. I haven't had mine long enough to answer your "how many hours" question. If the answer is not in other questions on this page, there is a similar device on Amazon selling for about $11. Somewhere on either that device or this one, someone said how long their's lasted on one charge. The time on the $11 device is probably the same as this one.

I don't have to charge it too often. It lasts me the whole day, and my lectures are 2 hours long each. So it holds a really good charge. Just make sure to charge it once you use it that day, or every other day. You know when it is fully charged when you plug it into your laptop and the light stops flashing. I charge mine each day I use it but I could even go every other day. It's a great recorder!

Hmm - I don't know that I've ever really checked the amount of time it takes to go from completely dead to a full charge. I normally just plug it in to an outlet and leave it for an hour or two and then it's good to go. You can also use the USB to charge it on your computer - which is nice. It's really a nice little charger - I use it all the time on trips, or if I know I'm going to be away from the house all day I'll keep it in my pocket just as a safety measure in case my phone battery dies.

I am unable to respond to this question, all I can comment about is that it charges up and then we can use it continually for several hours or days depending upon how long we keep it on.

How long you have to charge it depends on the charger you are using. I use a wall plug charger and I would give it at least 8 hours for a full charge. On a computer, I would say at least all night or more. I have had mine in my locker at work for weeks and it never lost it's charge and still charged my phone.

I have used mine for 6-7 hours more than once of of a full charge and it was still working great. Very happy!!

There is no way to know when it is totally charged. I just charged it up overnight and it held a charge for a long time.

I'm not sure how long it takes to fully charge; I've left it charging for up to two days and the charging light never shut off. My guess for how long actually it takes to charge is like half a day or something, but that's pure speculation. And to answer the other question: Yes, as long as you're reasonably careful.

I've never had it take more than 3 hours from completely empty, but it depends on what you're charging it with. As for how long it holds the charge, mine has held a charge for a couple weeks and any loss in capacity was not apparent to me. It may hold it longer than that, but I have used it so frequently that it has never been left alone longer than that. Make sure you charge it fully before first use, the longer the better for that. I believe the other answer was either a defective product or not fully charged the first time, because of how fast they lose the charge and how short their charging time is.

It seems to last a number of hours. I charged it initially and have had only one time where I ran low. It gets used two to three times a week and I only charge it once per week.

it has an internal battery that last up to 8 hours.it charges with a usb cable, and you can use it while is charging...

I don't know exactly, I just plug it, and leave it. whenever I remember it, I take it off the charge, and it'll be fully charged! If you put it in charge with less than %5 battery life, it'll take longer to be fully charged. I usually charge it whenever I use it, I plug it before I sleep, next morning will be fully charged!

You can go quite awhile once charged...I think at least a month if not more. You did remind me to check mine though since it has been awhile since I charged it! ;)I've never kept it plugged in though...only plugged in overnight to charge it up and it holds a charge for a good duration of time!

In my experience it depends on how far it has been discharged. The times I have needed to fully charge it, it usually takes about 2-3 hours.

This unit stays powered for approximately 5 hours on an ongoing basis when fully charged. However, it is VERY difficult to tell when it has (finally) fully charged. It takes forever.

I would recommend charging it for between 3-4 hours. There should be a blue indicator light on the side where the power button is that may turn off when its fully charged(if the device is already powered down)

When the unit is new, 3 hours on a full battery. The older the unit gets, the more that time declines. After about a year, it would barely hold a charge. I'm not sure if it is the battery/charger/unit itself. We replace the charger every 6 months and it gives us about 2.5 hours, and declines over time.

It takes about 30 minutes to charge. It will usually stay charges for around four hours.
