do i have to leave it plugged in to keep it charged?

No, I have not had it plugged in for 3 months, it has been in below zero temps for two weeks and it still has a good charge.
158707
No, I just get it a full charge and it does not die over time that I noticed

No, you do not. This box holds a charge for quite a while even after repetitive use. The manufacturer reccomends a recharge after each heavy use, and sometimes I don't do that and it works fine. I really feel confident I made the right decision in purchasing this booster box. Especially knowing that this is the same box AAA use during the course of a busy day.

No, it will stay charged for a for a good 6 weeks without being used in moderate weather. For the first 2 years I owned mine, I left it outside in the cab of the truck during the winter (which I think I should not have done) now this third winter I find it not hold a charge very well left outside during the winter months. It has a charger for the vehicle but that charger will not automatically cut off when fully charged which could overcharge the booster pack -- may hurt the rechargeable batteries; the AC wall charger will automatically cut off when the booster pack fully charged. Now last summer I was able to do 2-3 vehicles before having to recharge the booster pack. I hope I have answered your questions

I've only plugged it in the first day I got it (as per the directions it came with) It's been in the trunk of my car since then and still holding a full charge. I just used it again yesterday too.

I like to leave it plugged up to maintain the full charge. but this is a good powerful jump box. I used it to start my diesel tractor in 0 degree wheather . I left mine unplugged for about 3 weeks and it still had a full charge in it. this is a way better product than the cheaper jump boxes. it is worth the extra money in my opinion.

Yes you can. It charges when it's plugged in and I've used it for seven to eight hours and it still keeps charging.

Yes, it must be plugged in to be used. The good thing is, it won't run out of charge during use.

I believe either is OK. I usually leave it plugged in during frequent use. For storage, I unplug then charge prior to use.

Sure, it can be left plugged in so long as you want, its always charged that way.

No. When it's time to recharge, you won't have any power left to turn it on. Just plug it in and it will automatically recharge. A little light comes on to show you it's charging.

No, it will remain on until the battery dies. Then you will need to plug it in and recharge.

I would say not necessary, it's your choice. It stays charged even when its not in use.

you can leave it plugged in as long as you like. the light changes color when it is finished charging. will need new usb cord though. it may also break if you are trying to recharge a high amp device. my GF uses it every other day, it gets pretty hot when charging her phone.

No need to charge the battery first if you have it plugged in. There is a form without the battery, in fact.

You keep it plugged in and charging while not in use. When you are ready to use, simply unplug and it is ready to go. Very simple. Great machine.

No, you have to plug it in the charge it, but then you unplug it when you use it.

Yes. I usually just leave mine plugged in unless I am going into another room for a short time

No, but it charges quickly. As soon as I'm done I plug it in for about 30-60 minutes and it seems to keep its charge.

Yes, the keyboard needs to be charged. However, it seems to have a good sleep mode, so I haven't had to recharge it often, even when I accidentally left it on.

You can plug it in to recharge it, and I have used it while plugged in. I believe the instructions say not to do that, but it works.

Yes but generally speaking the manufacturer recommends leaving it in the charger only until it is fully charged.
