Question: Should the charger be plugged into this Lantern at all times?
Document: I wish I had this lantern years ago. Since I puchased it, it has come in handy 3 times in power outs. I leave it plugged in and when the power goes out the lantern comes on and lights up the whole room. No more stubbed toes. (Ouch)
In this day and age how is it possible that the electric lantern hasn't been perfected? This worked as expected a couple times, then it broke. Judging from the number of other reviewers, this should be considered a very expensive disposable light.
This lantern ceased to function due to a bad rotary power switch. The switch was hinky when I first got the lantern, but it worked if you played with it. Now it will not work on either of the fluorescent settings; only with the night light.My lantern was used only a few times, as it is kept at home on charge, standing by for power outages.
I purchased this lantern to have on hand in the event of a power outage. I've had it plugged in charging for two years and my opportunity came last week.
I have bought 2 of these lanterns and they are not worth the money. There is something wrong with the switch and it quits working after 20 or so times of turning the lantern on. The same thing happened to both of my lanters, so it must be a defect for the whole line of products. Also, there is no way to remove the switch to replace it. It is made in one piece with the base of the lantern. I will not purchase another one of these or anything similar.
I love that this lantern can be plugged into a wall socket and if the power goes off, it will come on (provided you have the switch to the high or low position). You can test it to make sure it is working by plugging it in, turning the switch to the high position and then unplugging it.
When left plugged in, the lantern will turn on automatically when the power goes off. For senior citizens especially, this is invaluable. Those of us at that age are usually experiencing increasing problems with sight and movement. Trying to function in the dark is downright dangerous and can easily lead to injuries.
Bought this to act as a back up light. Recently was home for the holidays and the battery was dead, in  spite of being plugged in all the time. In a power loss it should revert to the battery.By contrast, I have an older Coleman Florescent lantern that after more than 25 years, the batter finally gave out and I replaced that... It went through camping trips, etc...
This lantern worked out nicely for a few months of very light usage, and then it completely stopped working. When plugged in, the light flickers on and off, but won't stay on, and without being plugged in it doesn't work at all.My roommate has a much smaller lantern (Rayovac Sportsman LED Lantern, SE3DLN) that is lighter and has lasted him a lot longer... I think I'll buy one of those.
This is the second lantern that has failed. The first would not hold a charge. The second one died after 20 minutes. If you are thinking about buying this one, do a search on Amazon and see the other "Retro" listing (same product) with negative reviews. Very very disappointed.Update: The third lantern has lasted for years. I do not leave it plugged in as I did the other two.
