If the charger is plugged in but not the phone, does the blue LED light mean it's still consuming power from your car battery?

Mine goes off when I turn my car off, so if your blue light stays on when the car is shut off- you may want to unplug it.

Yes it is still consuming from your car but I always unplug mine when I get out of the car.

Plug something in while the car is running. Look for the light on whatever it is that you've plugged in that tells you it is being charged. Turn off the car and remove key. Is the light still on?

As I found similarly with the design of their car adapter, which showed negligible draw on the car battery when plugged in by itself, testing this charger also exhibited no significant power draw on the AC line when not actively charging.Because it doesn't even use an LED indicator to display that it's on, which almost every other device in the world uses, it's quite efficient and can be simply be left plugged in without any concern for wasting energy.

It depends on your car some cars have slow constant drains in them from security systems and lighting and advanced electronics and these would trick the Sansour into giving incorrect readings on your batteries voltage so most of the time the battery is suggested to be disconnected but if it's just for a little top off charge you can get away with it

Greetings from Venezuela. Clearly, if you just have to open it and cut the cord but not acerlo aconcejo and the LED tells you that is charging when connected to the power .... This led not spend any energy because it is an LED. not worth cutting it because you did not indicate if or when it is charging and is fully charged .........

The blue light stays on for awhile though does not seem to effect battery life as long as the LED flashlight is not locked on. I have enjoyed the unit and find it charges two phones overnight and shows blue in the morning.

After the battery is fully charged the light will turn blue. It is when you charge the battery in the charger dock. But if you charge the battery via the USB port, the light will be always blue and you can see if the battery if fully charged in your phone indicator.

Yes, once in the charger the functionality goes back to the phone. And you can pretty much tell when the Anker is functioning because it displays a blinking blue light (which sometimes wish was not as bright as it is).

When unplugged the unit auto turns off when the phone is removed from the wireless charger or USB. The LED is one while the unit is on to indicate the amount of battery. The Blue LEDs indicate charge, the red one is the on/off and Green is on/off for the wireless charging.

The phone stops charging when the light turns blue. It runs on AC still, so it's worth keeping it plugged in. It's not charging anymore once that light comes on, and it's not using the battery either. It's much better to keep it fully charged then to run it down before recharging it. Most cell phone batteries are that way. Most older appliances with rechargeable batteries are not (e.g. electric shavers and landline handsets). Those should only be charged when they get low. Different kinds of batteries are better preserved by different practices. New cell phones last longer if kept fully charged as much as possible. The phone stops charging when the light turns blue.

As long as a device is not actively pulling electricity through the port, then there should be no strain on your battery. Your lights drain your battery because the device is engaged and actively pulling a charge through its circuits. The only issue I have had with leaving the device on is that even when my car is in the garage, my phone still passes the calls through it. Makes for an awkward first 15 seconds of a conversation....

Depends. If the device is powered off it will almost always charge (slowly). If it's turned on it might either charge *very* slowly, or not at all, or even still lose charge if you're actually using the device. (You'll see the latter with high-end phones or tablets if you are running a 3D-rendered game -- the device will be using more power than any USB charger can safely deliver, so the battery will slowly drain even if it's plugged in. With a crappy charger this can happen even if the device isn't doing much.)

It's plugged into the power source, so my answer is yes. It's using power also so I don't know if you would notice it charging, but I can say I've used it when I had no power on my battery and it worked perfectly. I never noticed a drain on it either. It's like using the tablet while charging it. I hope this helps! :-)

most cars have the 9v outlet tied into the ignition, so it's not powered when the car is not running. Therefore, it won't drain your battery at all.

When the light is either red or some shade of pink/purple the battery is charging. When the light goes blue the battery is charged. I believe that once the light turns blue the charger stops charging the battery, but the light remains on. The blue light never turns off.

I assume you are talking about charging the unit, and if that is the case then J. Young is correct. You cannot seem to utilize the device while it is plugged in and charging. Another thing is that when it is charging the LED flickers all wacky like when it is on. Not a bad thing, but worth mentioning.

No, the light does not stay on. You should see that the phone is charging on the battery indicator.
