Can this item stay plugged into AC and stay charged up for use?

While the JNCAir does have a auto shutoff for AC charging, it is still not recommended to keep it plugged in all the times. DEFINITELY do not do that if recharging with DC power. Recharging with DC power works, but there is no auto shutoff and the battery (and you) might get damaged if left in too long. Charging with DC is only for emergency situations. basically, just leave it plugged in about 20 minutes to a couple hours, depending on how dead the JNC is. ok, sorry I went off on a tangent..so NO, do not leave it plugged in charging at all times, only charge it if it needs to be charged

Yes, you can leave it plugged in and ready for use. However, I found that you do not need to worry about it discharging without it plugged in and just siting there unused. It is amazing that once charged, it holds that charge for a long time. This is a fantastic product. It is better than any others that I have owned previously.

According to the information I read the built in charger is a float charger meaning it will not overcharge if left plugged in. There is something else offered if you keep it in your vehicle, they will send you mail when it will need a recharge based on when it was last charged. I might add I am very pleased with the performance of this unit.

I am not mechanically astute. Hopefully someone else can help you and I am going to be sure to check back for the answer. MayGod Bless You.

Probably not. I have not tested it that way but I left mine unplugged, did not use it for 4 days and it was almost dead when I tried to use it. However it does recharge really fast. I plugged it in and an hour later it seem to have a full charge. I use this little device daily so I just leave it plugged in. Maybe just plug it in an hour before you need it and use it that way.

it will not charge by ac.you will need to to use to also use an ac charger at some point over night charge (a dc charger will only maintain a batteries)

Yes, when plugged in the speaker will run off a/c while also charging the battery.

Yes, It can be used permanently plugged-in without overcharged. I've been using it that way for 2 years and the battery still works well when the speaker is unplugged.

No, the directions say you shouldn't because it could overheat. But it charges very quickly (5-10 minutes) and stays charged for weeks.

Yes it can be charged if you have an ac adapter. (None supplied with initial purchase). I do not know how long the battery charge last but think that would depend upon how many times the unit activated from movement, which is not predictable.

Wagan's Solar Cube charger is an actual floating charger, so you can leave it plugged into the AC outlet when not in use. Hope that helps!

Yes, you can keep it constantly charged. I like this tool. I have a large cordless but this is great for finer work. It has a surprising amount of torque. Very pleased. You'll need to get a set of smaller bits for fine work.

Yes. Unfortunately, the unit I received doesn't retain its charge for much time.

The person I purchased this unit for, leaves it plugs in at all time. She unplug unit for several day while on vacation, and the battery died. So I suggest you leave unit plug in at all time to preserve the battery life.

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.)
