Does this have a back up for when you have no power

Yes it does, it has a hand crank and I am very happy with this winch and I do a lot of hunting.

Yes, there is a manual crank on side of winch. Takes a long time to pull boat upramp but works very well.

No, Plus, there is no place for a battery backup in this switch. If you lose power, it is out just like a conventional light switch. When the power comes back on, the switch should reconnect to the wifi.

I does have a power cord I do not know if it has a back up battery.y husband just looked and didn't see one. Hope that helps you.

Mine came with the backup battery included. I run it on AC power, but it is very nice and convenient having that backup battery kick in during a storm.

This model is wired with a battery backup. You are better off with both power sources as you always have alarm protection.

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.

No it does not. Ac power plug only and batteries for backup in cast of a power failure. I believe the battery backup is good for about 8 hours. We are very please with this product. As I said before, it is a little tough to get the timer set right ( of course I am pretty dumb when it comes to these things ) but once it is working, you will almost forget about it.

Nop no battery back up. It just plug to the power outlet. Unless you connect it to a battery back up itself.

This pump, mounted to the ceiling of my basement, is a great backup pump because it works when the power is out. I don't think it pumps as efficiently as my electric pump in the pit, but it gets me through a power outage.

This thing is great if you need power or you travel and have no access to power

The new Drobo claims it has a battery backup that will allow it to save any unwritten data to the drives should power go out suddenly. Nothing states it will turn itself back on, and I doubt it will. Still, the new Drobo units are very unreliable and they have poor tech support.

It does. However I returned it soon after getting it. It was simply not enough power.

If you're having so many regular power failures you should have backup power anyway since that kind of thing is really, really bad for your system. At some point you're absolutely going to lose data or your system will become unstable. - Trust me, I work in IT.

The power supply is an option. It uses a 9 volt battery (not supplied - no surprise there). When the power supply is used, the battery functions as a back-up.

Yes, but it has an option for batteries. I suppose it is in case of power outage.

It plugs in and uses the battery for backup in the event of a power failure.
