For how long should this lantern be charged with the ac charger ?

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!

If there is an AC charger then I didn't get it and I have no idea where you would plug it in. I am under the impression that it is only a solar powered light. It has a small PV panel on the top that collects the sun and stores it. THat is how you charge this. IT is an incredible little light.

Mine didn't come with a charger. I just put it by the window, and keep it charged. (it's probably overcharged, but always ready.) Today is a typical blah November day, very overcast with no sun in sight and it's charging. I've even noticed the charging light on when there's enough lamp light at night.

Although I purchased an AC charger I have not used it as I just leave them in sunlight & they do just fine. As stated previously it doesn't take too much light to charge them. However I did have a question myself and went to d.light's website and under "Contact Us" I emailed my question to them and within a few days I received a reply. So you might want to ask them directly although they do not sell the charger it is by Nokia AC-3U Travel Charger.

It does not plug in. It is strictly solar. If it does have a plug in option I am not aware of it. It seems that for every hour you charge it you get a little bit more than an hour of use.

It depends on your charging method. A few hours via AC power with a depleted battery. Crank for two minutes, rest for a minute, and repeat.

I think it depend on how "smart" the charger is. As I understand it, lead-acid batteries require a three step charging process, first the actual charging, second, a top charge, and then a float or trickle charge to maintain the charge over time. Maybe the rechargeable lanterns have this sort of smart charging. I hope so, and so far have found no definitive answer. My own testing confirms the lantern charger handles the first two steps well, so probably it does the maintenance charge as well. Too bad, isn't it, that rechargeables lose power over time, whether used or not.

I am looking at the operator's manual for this light. It states "charge the unit before first use using the 120V AC charger for 2 hours or until the battery status LED lights green." "The battery status LED lights red when the unit needs charging." It further states "When using the 12 VOLT DC charger,DO NOT CHARGE FOR LONGER THAN 2 HOURS." So it appears you could leave it on the charger when using the AC charger, but not when using the DC charger. If you buy this light, I am confident you will like it. They have a similar model now that is supposed to be waterproof, but I would stick with the SL5 as the new waterproof model appears to have a problem with the switch. Good luck!

For recharge, use AC adapter (included) or battery to charge for at least 5 hours.

I think it took about 4 hours. When it's charging the light is a orange color. When it's being used the color is then green. Mine can be used for about 4 minutes when it then needs to be re-charged.

Not very long. It is always charged and ready for me as I replace it on the charger between uses.

charge it as many times as you want by the sun depends on how much sun you get it takes about 3 days for 100 percent. to help get to 100 % you can charge it by a lamp or any light.

You can charge until the green light on the charger comes on. A matter of a few hours. Good luck. An overnight charge will also do it with no problem.

Hi, not going to lie to you, this is an awesome product and when i show it off, the guys who one a different model gets jealous and the ones who don't have one, buys one. Now with the red light, I normally charge mines for 3-6 Hours and never pay attention to the light but when in use it stays well lit for hours. (varies on brightness) To be safe try 3-6 hours and see how long it will last depending on your usage. Hope this helps and enjoy!

I use mine only once a week, but according to the guide, it states that battery is fully charged when green light is on....approximately 8 - 10 hours to fully charge a discharged battery. Hope that helps!

ac adapter comes with lamp, but charger does not. The lamp does not give off very much light, if you are going to use it with the ac adapter there are better choices.

Like I said, I have not charged mine by USB. Just plug it in and see, it won't hurt it. It will probably take longer to fully charge by USB than by direct sunlight, so just leave it charging overnight and check it the next morning. I found that they only way to make the light go out is by covering the solar screen, or putting the lantern in the dark. It seems to glow otherwise because any light seems to charge it in some manner.

I use a, seperate, plug in charger, and it takes about 30 minutes to charge. The charge lasts around 10 minutes. Less if you use the lights.

Yes, I use my cell phone charger that is plugged into the house current to recharge the lantern.
