If you have this plugged in and charging via the USB cable does it still automatically shut off, or does it stay on. Can you cancel the auto shut off?

I wish I could help, but I don't have this device, so I have no experience with it. Sorry.

I will add, when you are not charging your phone or when your phone is fully charged, make sure you remove cord from the charging device altogether... The device doesn't have a shut off capability. If there is a cord plugged into device, it starts using its power if it the cord isn't hooked into anything else. If your device is hooked to your phone it doesn't stop charging at 100%. The only way to shut off device is to detach everything from it

Hi JustJohn, I didn't buy my portable from Amazon, I got it from Groupons. To answer your question yes it does turn off when it's finish charging.

That's happened to me on occasion, but it usually reconnects on its own. I find that it does the disconnect thing more often when it's getting closer to time to charge it. I think may be some power saver feature.

There is a button on the bottom of the charger for power. Once you take your device off charge it will shut down automatically after a minute or so.

Hi Jay,Mine works for as long as it's plugged in- I do sometimes unplug it to move it to another plug to do the next room, but it's never shut off on me. Thanks, REN- I do clean mine after every use so maybe that's why?

I see the first answer of this question mentioned that it should be disconnected as soon as it has full charge or almost full charge. I understood the different way. It can be charging for 24/7 continuously without unplug until you are going to use it. So which method is Righr?

No I've charged it time and time again with it off. Its best that it's turned off during such process due to the fact in its on state it will be corresponding as a active device.

it does have an auto stop when charging with AC. The light will go from red to green to let you know it is fully charged. You can leave it plugged in without damaging the unit. You can not do this with DC. as with your car lighter socket. You can overcharge the battery and damage it. Hope this helps.

On mine you have to hold the on button for approximately 3-5 seconds to turn it off. The lights go out a few seconds after turning it on regardless of whether it is on or not. AND if it is on when plugged in to charge, it will not charge no matter how long you leave it plugged in. This is the most annoying feature of the device.

Hi Mark-yes it does stay on when not plugged into a device. I unplug mine when I leave the car b/c I don't want my kids to decide it's theirs b/c it's unattended! I don't know of any converter that turns itself off.

While the JNCAir does have a auto shutoff for AC charging, it is still not recommended to keep it plugged in all the times. DEFINITELY do not do that if recharging with DC power. Recharging with DC power works, but there is no auto shutoff and the battery (and you) might get damaged if left in too long. Charging with DC is only for emergency situations. basically, just leave it plugged in about 20 minutes to a couple hours, depending on how dead the JNC is. ok, sorry I went off on a tangent..so NO, do not leave it plugged in charging at all times, only charge it if it needs to be charged

Yes it shuts off when charged and also shuts power off to the charger until voltage in battery drops to a preset level. I am able to keep the charger hooked up for months without worry.

How long is a guess. I guess it's too expensive to put in a voltage detector for shutting off the charger when it is at peak. Yes, you can charge with it shut off. It asks if you want to continue charging when you shut down.

I just leave it alone. As long as its not charging another device it will turn off on its own.

Yes. It automatically turns on once plugged in, but can be shut off while charging.
