Cordless phones & ac adapters

[tutusue]

An untechie tutu question:

Are the adapters interchangeable between cordless phone bases? IOW, can I remove the old phone and plug that phone's adapter end into the new phone's base? They look identical. Different brands. Don't wanna blow up 666 condos!

666??? The Number of the Beast! Whew.

Make sure the specifications are the same, amps, watts, output voltage, and be sure the +/- indicators match and you should be good to go.

Best bet, however, is to use the new one, and if it matches, keep the old one in reserve (even electric parts wear down). Or vice-versa, use the old one and keep the new one in reserve. But only if the printed or embossed specifications match 100%!

Re: Cordless phones & ac adapters

The best way to answer this question is to look at the label of each of the adapters and of the devices that use them.

The thing to look out for is the output of the adapter.

For example the various adapters lying my desk says:

Output: 12.0V, 1000mA
There is a symbol that says that the center of the plug is postive.

Output: 7.5V, 1.4A
Symbol that says the center of the plug is postive

Output: 5.0V, 350mA
No symbol that says if the center of the plug is postive or negative

The 3rd adapter is my cell phone recharger, while the other two are used to power controller development boards

Re: Cordless phones & ac adapters

Thanks, Kaonohi and Helen. Very helpful. Everything's the same except output. One is 6.5V, 500mA. The other is 9V, 350mA. Guess it's time to unroute the old cord and reroute the new one. Was hoping to avoid that!

Helen was the real hero, with specific examples - I was only the Distant Early Warning System. Lucky you didn't try it without asking! Hooray HT!!!

Re: Cordless phones & ac adapters

Heh! The only reason I didn't try it without asking is 'cuz the old phone is a 5.8 GHz and the new phone is a DECT 6.0...whatever the heck that means!!! And, yes...HT rocks! <smooch>

Just different transmission standards; DECT = Digital Enhanced Cordless Telecommunications. 6.0 is the USA standard, slightly different from those used in other regions, because of radio frequency usage in the US.

Re: Cordless phones &amp; ac adapters

I pay $39 for a set of 4 cordless phones from Heartland America and when the batteries run out on the phones I pay $25-30 for each battery!!

This is exactly why I bought a new phone! It cost more to replace the batteries.

You mean the new phone you bought doesn't need battery replacements ever?

After spending a $100 bucks to replace batteries on a $39 phone I was about ready to buy a new phone too, but if I have to replace batteries on all 4 of the phones what is the point really?

The spectrum band for DECT 6.0 in the USA is 1.9 GHz — which is helpful since it does not interfere with the crowded 2.4 GHz frequency (which is used by both 802.11b and 802.11g WiFi networks, as well as other cordless phones). 1.9 GHz has been reserved by the FCC exclusively for voice communication applications.

Thanks for the additional detail, TuNnL.

It uses 2 AAA Ni-MH rechargeable batteries that can be purchased for $6 to $10. online...or $19.95 at panasonic.com!!!

Do I understand correctly that you purchased a set of 4 phones with batteries for $39.? If that's true then you'd save $61. by purchasing a new set of phones and tossing (well, recycling) the old set. Sorry if I misunderstood your purchase.

Thanks, TuNnl. That's good to know. I was getting a lot of static with my old phone. Everything is plugged into one phone jack...DSL wireless router, fax, phone (which is plugged into a filter). New phone got static, too, until I unplugged the fax from the phone jack.

Re: Cordless phones &amp; ac adapters

Hawaiian Tel provided me with a filter to plug into the outlet, between the phone line and the modem. They said with that filter, there shouldn't be any interference. I was told that also affected my fax machine too. of course, that was for my DSL line - I don't know what kind of connection you have.

Sounds like we have somewhat the same set-up except HawTel told me to plug my phone into the filter. I should add I have a triple adapter in the single phone jack. Filter in one puka, fax in one puka, router in one puka. Phone is plugged into the filter. Lotsa static with this configuration. Unplugging the fax helps which is fine because I don't use it very often.
