Do these require electricity all the time or are they chargeable?

They require an electric connection. I believe they MAY be able to run off a heavy duty 12 volt rechargeable battery, but I have not done it that way.

I have never needed to charge the by plugging them in. I think they work off of both, bu I am not certain on that. I just place the lights in direct sunlight or if it is cloudy just set them outside to recharge them. This always works for me. Hope this helps.

I usually only have to charge them for half hr-one hr. When the talkies no longer show low battery, they're good to go.

you can charge them as much as you want they don't acquire a 'memory' but as soon as the fully charged light comes on remove from charger they can be damaged by being left on charge they don't seem to discharge just lying around the mah hours on these batteries are greatly overstated

Good question, I tried to charge mine using solar recently and they did not charge . I have been very busy recently and haven't had a chance to figure out what is wrong

They are rechargeable. and it is powered by an AC adapter. Like other have said, I would not purchase these. They are very tight on the head and the inputs are not stable.

Yes. They charge and then they just maintain. What you're suggesting is what I've been doing for quite some time with no issues at all.

Mine charges in about one hour but my husband had trouble because although he plugged them into his computer they did not charge because his computer was in sleep mode and not on. be sure your computer is on also.

I have only had mine for a few months, ive had no issues with them holding a charge. When we were out of power for three days this summer, it was on and working all night and charged all day with regular daylight and was ready to go for the next evening. I just bought four more so we will have enough for the house.

Yes they do. They need the power source. I bought these for my son. He loves them.

Yes as they do not come charged. I recommend the nite core charger for them. ESP with the digital display.

Not sure, I just put them on the windowsill and they are fully charged at night. BTW, I accidentally left one on and when I saw it in the morning, the LED was still emitting a faint light! Also, even the faintest light will charge these, they don't even need direct sunlight!

You can do both. I usually charge them, when not using them, in the off position. When I am using them for long periods of time and I notice they are starting to die I will plug them in. Either way is fine though.

They are designed to be plugged in all the time you are not using the cart. This way your batteries are kept at 100% charge and will last longer.

I think the answer is yes but they've probably been sitting in a warehouse and have lost some charge. They always need to charge when I initially install them (right after receiving them)

no they come with their own rechargeable battery packs. we use them everyday and have had no issues as of yet.

Yes, these are rechargeable. Charge via USB to outlet or PC/Mac. I've had them for a year and my daughter loves them.
