When the battery is fully charged it automatically switches to "trickle" mode to keep the battery topped up until you disconnect it.

It has a blinking red light when the battery gets low. Also, when you charge it, the red light comes on. When fully charged,the light goes off.

The fan does turn off after 100% charge is reached. The fan does turn on occasionally when trickle charging for short periods of time. I use my charger to keep the battery charged for my back up sump pump and it has worked great.

No it Does not. As soon as you connect a cable to charge the battery pack the outputs will turn off.

Shuts off with timer only. Does not sense when battery is charged. I have owned the charger for about 6 months and am very happy with it.

No, it shuts off if the batteries die. It may buzz when the batteries are just about to die.

Yes the unit will stop charging the battery when the charge cycle is completed.

Yes, it'll go into standby once the charge is complete in order to not overcharge the battery.

I cannot say for sure since I have never let my battery run down, but I do know that unlike some other lights it will still turn on while charging,

If by "automatic cut-off" you mean it stops charging when the battery is full, then yes. It does have automatic cut-off.

No, you have to plug it in the charge it, but then you unplug it when you use it.

No, the unit is either on or it's off. It does not shut itself down. I leave mine on 24/7 since it draws very little power when not playing music.

Yes, the battery goes down. I added a powered USB to the device that extends the battery, but still the battery level goes down meaning it does not charge as fast as it discharges.

well, connor h is right. it does not shut off, per se, but with the controller, it will not overcharge your battery.

I assume that you mean "does it stop charging once the battery is fully powered?" My understanding is that this one does that, and seems to keep the battery charged if it stays inserted. The small chargers that came with my tools did not do that.

Leave the power cord plugged in to the unit at all times, it only charges when the battery needs re-charging, shuts off automatically.

It shuts itself off when the batteries run down. You can shut it off manually before then if you want.
