Can the power cord be used to power the lights directly if the batteries die or is the power cord only for powering the battery charger?

UPDATE - 5/16/2014: Although the adapter does power the light, I noticed when a battery is also attached, after a while, the light will slowly flicker. This is probably due to both the battery and the light draining power from the adapter at the same time. Therefore, you should REMOVE all batteries when using only the adapter to power the light. Previous answer: Yes. It powers the light without batteries.

Well -- sort of. The power cord does connect directly to the lights, but I have found that it often makes them flicker depending on the power source connected to. I now use them only with the batteries. There are many inexpensive long lasting after-market Sony-style batteries which work with these lights so I now have plenty of batteries. UPDATE: The flickering is due to the power supply being too small to actually power the light. if you purcahse a bigger power supply, that should work. However, I find the the batteries last a long time, and when i use the bigger Sony style batteries I can get nearly all day out of them. Batteries like these: http://www.amazon.com/Sony-DCR-VX2000-Camcorder-Battery-Lithium-Ion/dp/B00301UMEK/ref=sr_1_1?ie=UTF8&qid=1417207198&sr=8-1&keywords=sony+np

My basic answer is that the converter is used to charge up the battery for later use when not hooked up to a 110V circuit. Without the battery there would be no 12V lights or other usage low voltage use. The converter would operate but what good do you get from it?

I have mainly used mine with the power cord and the batteries inside. I would think that it would work with the cord only.

I am an electrical contractor by trade. The lights are very low amp draw and should not be a problem being powered by a cigarette lighter adapter. Obviously, they are typically permantly mounted and hardwired, but I see no reason they could not also be utilized in a portable type use and powered by any 12volt DC source.

I believe just uses the regular batteries or perhaps could use rechargeable batteries but does not charge the batteries, nor a usb. a simple lamp that works for our purposes very well. great for camping too.

Sorry, I didn't use it to only charge the batteries. I just use for devices with the AA or AAA battery.

You have to plug the lights in anyway but no, you don't have to use it the lights have a separate cord.

If you can run the connecting wires between the lights you won't need additional power supplies. If you can't us the connecting wires, you will need additional power supplies and switches. Hope this helps.

Mine doesn't work anymore either. I was thinking about buying another one from Amazon power pack for led lights. It has 5 volt output 8 amps. Should last longer for 14.99

This is designed to charge your battery or batteries, not to directly power lights and fans and whatnot. I have mine set up in conjunction with a solar panel grid. Each runs through a charge controller of its own and into a distribution block before going into the battery bank. To run lights or AC powered items you will need to either use a power inverter connected to your batteries. This is a great little turbine but its not designed to power something all by itself. Since wind speeds vary its power output will vary. you will want a charge controller to cut off power flow if the winds blow too hard or if your batteries are fully charged to prevent overcharging. think of the wiring like this: turbine&gt;charge controller&gt;battery bank&gt;power inverter&gt;lights and fans. I hope that helps. If not search YouTube for a guy named LDSprepper. I wired my solar and battery bank like his but I added the turbines for cloudy days.

It has a power cord. I did build a timer circuit to time the lights in the proper sequence. It works well.

This is just a guess, but LED light technology is such that the light will still work even if there is just a little power remaining. There just might not be enough power left to charge your device. It's possible that you just have to re-charge your battery by plugging the micro-USB cable into the battery and connect the other end to a power source. If that doesn't work, contact the manufacturer.

Depends on your use I would say. In my case an AC to DC power supply would have not been used since I am using a DC source to power the LED controller and repeater.

Its like any other battery power device. It will last as long as the batteries. This one is plugged in (that's how it recharge) but it will last a little while on the battery. Can't tell how long exactly though. Not sure why you need battery only but that's definitely a high-end video monitor, i don't think it will last very long without a power outlet.

It is primarily a charging cord. If run dead may take a few minutes to come up but the draw down on this is not bad so should be pretty operational within a short period. Excellent light and extremely bright.

No...the low voltage output has screw terminals used for wire connection to the lights. The 115VAC power cord has a three prong grounded plug.

The light comes with both a AC and DC power cable, which charges the battery. So, you can charge both at home and in your vehicle.
