Panasonic KX-TCA200 Battery Back-Up Power Supply

I bought and installed this battery backup device about a year ago on my KX-TG5633 system since power failures are part of life where I live. Works perfectly and seamlessly to keep the telephone base station powered up when the lights go out. The remotes, of course, continue to work as before using their internal batteries. Just bought another this week for my elderly mother's phone to avoid a repeat of the panic which ensued the last time her lights went out.Read the label on your phone, and if it uses either 6V or 9V DC (200ma - 850ma) power AND the power adapter has a 5 mm barrel connector with center negative, outer positive polarity then this device should work with your phone. Use AA Alkaline batteries, install 4 for 6V, 6 for 9V. You want the long shelf life of the alkaline cells so the battery pack will work when you need it, so don't use NiMH of NiCd rechargeables. If a power outage exceeds a couple of hours, I replace the 6 AA cells.The Panasonic power adapter which came with my KX-TG5633 is labeled: POLV1 9V, 500ma

I'LL KEEP IT SHORT AND SWEET: I WAS JUST TOLD THAT THIS PANASONIC POWER SUPPLY DOES NOT WORK WITH MY NEW PANASONIC CORDLESS PHONE SYSTEM, MODEL NO. KX-TG4031. EVEN I JUST PLACED THE ORDER 30 MINUTES AGO, IT IS ALREADY IN PROCESS AND CANNOT BE CANCELLED OR CHANGED.THE THING PROBABLY WORKS WITH CERTAIN OTHER PHONE SYSTEMS, BUT I SHALL BE STUCK WITH A USELESS BACK-UP POWER SUPPLY FOR MY PHONE'S BASE UNIT. BUYER, BEWARE!

Panasonic KX-TCA200 Handset Even though the product is described as a handset, I knew I was purchasing a backup power supply. The problem is, it doesn't work with the new phone system I purchased at the same time, even though the Panasonic packaging indicates that it should! The plug does not fit the jack on the phone. Fortunately, I purchased this phone system to supplement an older Panasonic system, to give me handsets in more rooms, and the power supply does work with the older system. At least I will have two working phones if the power goes out.

does what it is supposed to do, happy with product, t

This works fine as a battery backup for Panasonic cordless base station. Would be even nicer if it were rechargeable, it does take disposable AA batteries, but for the price it works well.Note the product tile on amazon is wrong, it is a battery backup, not a 'handset'

I purchased the KX-TG5776S phone system, and the Panasonic WEB Site shows this (TCA200) as an accessory (10-10-2006) BUT IT DOES NOT FIT THIS PHONE. I called the Panasonic help and they told me I got the wrong thing that the TCA200 did fit that phone and that I should order it directly from Panasonic. So like an idiot I did, and voila, its the same part, still doesn't fit. Called Panasonic again, this time the person said they don't make a battery backup for the KX-TG5776S yet and that the "other" Panasonic person was mistaken. Now I'm out over $20.00 bucks in shipping costs and still don't have a phone that works when the power goes out. Its quite possible the TCA200 works, but just not with the Phone system I purchased.

This item does not do what i thought it would do.I thought if the power went off, it would automatically supply power to the phone so you would not lose all of your settings.

I missed in the item description that this unit will not work with Panasonic cordless phones made after 2006. So, check to make sure. It does not work with my KX-TG5777 unit. It should have rechargeble batteries so that they are always charged, and not have to remember to replace the alkaline batteries periodically.
