Can I leave the light on 24/7, or will it not charge if left on?

We recommend turn it off after usage, since the panel is not designed for 24/7

I think you would need to install a photocell, so it would charge the batteries during the day.

It seems like it charges some. Mine died on me after hours of being on. Didn't think about turning off. Latter next day I noticed it was on. One note though The solar panel is small and not of the latest technology. I doubt you would get as good of charge if left on. Hope this helps some.

Mine doesn't turn off either - I charged it over night, and all 4 lights were still blue in the morning.

No you can't just leave it on. There is no real on and off switch for that. BUT it does turn on once movement is detected. It is very sensitive. Right now, mine is set for movement up to about 50'. I don't know how long it will run with constant movement. Light is very bright. I was impressed for a solar LED light. It is excellent when used as a security light or when needing help to find your way in the dark. Only had it up for about a month so can't say much about how long it will last.

The light should blink off and on I believe, as it's being charged. Is the system charging up after you leave it plugged in for a couple of hours?

You can leave plugged in 24/7. Only operates when unit receives D C power from panel and A. C. power from grid

I don't charge mine very often as the charge lasts a very long time. To be honest all I do is plug it in overnight and unplug in the morning. I've never looked for the light to change. Sorry that doesn't really answer your question but it's what works for me.

I see the first answer of this question mentioned that it should be disconnected as soon as it has full charge or almost full charge. I understood the different way. It can be charging for 24/7 continuously without unplug until you are going to use it. So which method is Righr?

Yes, you can leave it connected all of the time. It'll automatically stop charging when the battery is full. But why would you want to? The charger is always converting 110v AC house current to 12v DC battery charging current. That produces heat and wastes electricity (aka $$$). I unplug mine when the light goes green meaning the battery is charged.

No. The light should stay on until you turn it off. Mine has stayed on for hours at a time.

No it will continue to charge even if you bring it to total darkness and then back to light. You can tell it is charging when the red led is glowing. Charging is very slow even in strong sunlight

Hi. I think the light stays on as long as it is plugged in. I don't think it goes out when the device if fully charged, but I could be wrong. To be honest, I never paid attention. It is fairly bright, though. You wouldn't want to charge overnight in a bedroom. I usually plug mine in in the kitchen. Good luck!

Should turn off during the day as it charges. If not the light is not very bright and weakens quickly.

Yes the light does stay on if the unit is plugged in, this indicates that the unit is working and charge is available to be used.

No. It Does that while it charges. When it is done, all the lights will go off

I don't see any reason to leave it plugged in 24/7. When the battery gets low a little red light comes on to remind you to recharge. I imagine this lantern will hold a charge for quite a while. I use mine every morning, 1/2 hour to 3/4 hour at a time, and probably recharge every two weeks or so.

Yes you can, if you leave it plugged into the usb port on the computer the lights will stay on unless you turn them off with the function + F5-F6 keys.

I'd not assume it's safe to leave it plugged in unless you see a statement saying that it is. In fact many manuals will say "Don't charge for more than 24 hours" or "Don't overcharge" showing that you shouldn't leave it on. If your thinking of that so it has a routine "fresh charge" that you don't need to think about doing regularly I'd get a timer that turns it on for just 15 minutes a day and/or a regulated power supply (like the Schumacher PC-6 or Coleman powerchill cooler AC supply) that won't "overcharge" it.
