Do you have to keep it charged (elctrically connected) for all days? If you need it and if it is not chraged than it is useless.

I had it charged up and then unplugged it. The next day it wouldn't open one bottle. It needs to be charging all the time.

You can keep it plugged in all the time and you won't damage it. I think it takes at least 20 hours to fully charge it, after it's been totally drained of it's power.

My experience is similar, although I don't usually use it constantly all day. I keep it charging whenever I'm not using it.

Does not have to be plugged in all the time. Just after using it and every 30 days. I don't know how much current it uses but you can keep it plugged in and it'll stop charging it once it's fully charged

Yes. Just keep it plugged in 24/7 and you wont have to worry about the battery going dead or having to reconnect it.

Mine kept its charge for a couple of month. Since the connector broke the first day I tried to use it, it was in my drawer until I received a new connector.

Several hours. Check the item description. and google the item title for blog discussions for more details. I think it also matters on what you hook up to it, but I'm not certain. It's also ok to keep it plugged in while it is in use.

I don't believe you can specify which days like your example. If your electronic is only plugged in the device during those days, it would still provide what you want. You can also hit a single button to turn it off on days you don't want it operate... You would just have to push it every day.

I haven't had any problems with it holding a charge. I have noticed if I don't use it for a few days it doesn't work. So I would suggest charging it every other day or so. If mine is charged it usually lasts a couple hours.

You can leave it plugged in if you wish. I usually unplug it after fully charged and let it sit. It keeps the charge for many weeks.

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 maintain a charge, but if you're watching movies it may discharge even while plugged in. That's how mine does.

I keep it plugged and use it every morning so I never have it run out of charge. I think it will run O. K. if you have to plug it to finish in the event the battery runs out.

No, but you could keep it plugged in for use if you were concerned about battery life.
