Does this have a backup battery for power outages? Can it be connected with a case?

Yes, it has battery backup. It take 3 AAA or AA batteries, I don't recall which. Also, if your phone is plugged in when the power comes back it would automatically set itself anyway. As for the case, no, it will not work with most cases without a connector extender. There is a plastic bar that is designed to sit flush with the bottom of the phone/iPad. Having said that, if you can find a case that does not cover the bottom of the phone at all, saving the rounded corners, then that would work. As an example, it does work with the Sipgen Air Skin case. Another option might be some careful Dremel work...

The unit has a battery for memory only so if you unplug it for a period of time all of your settings are saved once power is restored.As for the case, Yes it is possible to charge with my case on but keep in mind there are many different styles of cases.

Yes has a battery backup. Can be connected with a case by connecting with the lightning charger cable.

Yes it does. If you loose power it will automatically go to a buzzer alarm...As for the case I cannot charge it with it nor my iPad �

This is a back-up battery designed a carry a small load for a short period of time, like an alarm system if the house power fails. Consider a motorcycle battery.

No. There is no built-in storage battery; so it must be connected to AC power.

This battery is usually used as a back up battery in an alarm system. It is 'rechargeable' in that the alarm system provides a trickle charge to keep the battery charged and to recharge it after it may be used during a power outage.

This system does not have a back up battery but you can always buy a UPS (uninterrupted power supply) battery back up for it. You will plug the back up battery into the outlet and the system into the back up battery outlet. I plug this system above my dropped ceiling in my business and all the wires were ran in the exterior door's molding. The exit button wires were ran through the wall and around the exterior door's molding and connected to the keypad. The UPS can be used on anything like computers, alarm systems or any kind of medical devices that need power to stay on even if there is a power outage.

Any of these products without a backup battery is worthless during a power outage, which is precisely when most CO poisonings occur. Many occur at night, when you're not able to see that the little red light is no longer on. It's you life and health . . .

The theory is that it is a power outage backup. The problem is that it goes dead even though it is supposedly not being used. Without the battery you get warnings.

Yes, this can be used as a backup source for an internet modem or router, but because it will not last long once the power is out, it makes more sense to us a APC UPS 350ES (or equivalent) backup battery/surge protector instead.

I'm not sure, because we use it as a battery backup to our server. The times I've needed it, we've gotten at least 2-3 hours of backup for our server before our electricity came back on.

No, it does not have a battery backup since it is a surge suppressor. I have used these Tripp Lite devices for many years in my job as an electronic technician and have never known one to fail. A device with a battery backup would be an Uninterruptible Power Supply, which is another good choice to protect your equipment, but somewhat more expensive.

I only use the AC adapter, but I know the battery is an alternate power source so it would make sense to me that the battery would serve as a backup in the event of a power outage if you also use the AC adapter.

Having an emergency backup is good but if you dont know its status... you may get a bad surprise.the charge stand is needed to keep your place tidy..

it has battery backup in case the power goes out, but it does plugs in to a wall outlet' I love this clock because I can set 2 separate alarms for weekdays and weekends!!

I run this from the outlet, and it's been exceptionally reliant. There's a back-up battery for emergency power outage.

Yes, it does. It has a battery backup (9v) to keep programmed numbers and the message stored during any power outage.
1033749
Yes. I purchased it to replace the same battery that was in my home alarm unit. It serves as a back-up power supply in case of a power outage. It works dependably when the electricity fails (that doesn't happen here too often).

You must supply a power source, so battery backup would be a good option to think about.
