Does the unit have a cut off feature to protect the battery after it has recharged?

The unit has a "smart" charger built into it. The charger will charge the intrernal battery to a full charge and then automatically switch to a "trickle charge" mode to maintain the battery charge. Yes, you can leave it plugged into 110V indefinitely - nothing bad will happen to the battery. In fact the user manual that comes with the unit recommends keeping it plugged in between uses.

It is mainly used to "jump start" your battery, and not used as a "battery charger". Hope this answers your question..

I have power ran from battery straight to cap... It does turn off after it is fully charged up! It's actually pretty cool.

No, it has a separate battery with charger. I keep two, so its easy to switch out when one runs low.

Not that I am aware of. It is a nice battery case and will provide some protection.

It has a display for the battery banks and shows the charge progress. When a battery is done charging, it shuts off that bank...It's an awesome little unit!

No, it has a switch that you can turn on LOW or High or Off. It does not cut off automatically. I always unplug the cord from the cig. lighter. Hope this helps.

Yes, under the bottom there is an off switch. Also on each side of the off switch is a setting you can switch from rechargeable batteries to regular batteries. I hope this answers your question. Very glad to help.

Yes, once the unit has been plugged in and charged, it has a back-up battery that will preserve time and settings during intermittent power outages.

Yes there is, however there isn't an automatic 'shutoff' for the DC application, so you have to monitor the charge and manually unplug the cord when fully charged.

Yes it does, it has a Delta Peak Detection so when the battery is full it stops charging

not that I am aware of. Light turns green when charge is full and I shut it off.

The unit has a compartment for two button type batteries (supplied with the unit) that back up the memory if the power goes out. So the answer is: yes.

No, I do not believe it cuts power, but I also believe that most recent android phones, iPhones and tablets including iPads are not susceptible to damage from remaining connected to the charger and automatically go to trickle charging. I regularly charge these devices overnight without having to start at empty and have experienced no reduction in battery life in any device that would indicate battery damage.

yes thats usually the battery one would have separated to eliminate the possibility of it draining

No. you have a built in charger in your unit and it will top charge the battery in case it is a little bit discharged.

Yes, there is an on off switch on the bottom. I always turn mine off when I'm not using it and it's in my case so that the battery doesn't drain and it doesn't do anything when I'm not using it.
