Well, When I say droped call, the 2 lights on top of the MJ plus would not even be on when it overheated, the green and yellow lights would not even be on, then I took it apart and had a fan blowing on the electronics and it worked fine.Sometimes even with the electronics exposed and NO fan, it would get hot the the Green and yellow light would be off and of course not dial tone.

I usually don't look at the lights when any calls are dropped. I'm usually out in the garage. So I cant observe very easily from there...lol. But Ill be more aware of them now. My last drop off happened 2 days ago after about an hour conversation, it just goes silent for 2 seconds then went into a dial tone.
Even with the fan blowing. It appears we have more questions than answers.

The MJ network USUALLY (but not always) automatically disconnects your call at around the one hour mark; sometimes sooner, sometimes later.

I've had conversations on my MagicJack Plus for over 3 hours many times no drop offs. I remember my older magicjack would drop off at exactly 2 hours exactly every time. But this MJ plus has various results. This is what were trying to figure out. The inconsistency, hopefully well come up with some answers.

- Good luck with that Wink You'll find it's not related to heat or whatever... the network EVENTUALLY disconnects regardless of MagicJack device model, whether or not the MJ+'s casing is pulled apart and a fan's blowing directly on it, etc. In the past, at least, the company has claimed that it reserves the right to do this in order to ensure that its servers don't get so overloaded with so many extremely long calls (or calls made by callers who forget to hang up when they're done) that other customers aren't able to place new calls. When it happens to me (again, usually around the one-hour mark but a year or two ago it *used* to occur at around the half-hour mark... they've since increased their network capacity quite dramatically) I just immediately call the other person right back. Still beats the frequency with which my cellular calls get dropped - by about 1,000 percent.

I feel we are getting better information from this forum than the MJ "Tech" line. I have more confidence from the people in here .

PostPosted: Wed Nov 21, 2012 9:14 pm    Post subject: Passive heat sink cooling suggestion for a MJ+ using a power

Passive heat sink cooling suggestion for a MJ+ using a power adapter

-The first time I used the power adapter with my MJ+, the MJ+ became so hot after a while it was uncomfortable to hold - way too hot for electronics to stay healthy. The heat seemed to be coming from the power adapter plug as it was very hot too. I agree with other posters who believe that at least part of the problem is heat traveling from the adapter through the metal to metal USB plug and socket into the MJ+. I haven't had heat issues when running the MJ+ from a computer USB port.

-As other posters have suggested, I added the short USB cable between the MJ+ and the power adapter and the MJ+ was noticeably cooler .

-I also added two passive heat sinks to the MJ+, and the MJ+ hasn't been more than comfortably warm since.

-Specifically, I put a round cake pan upside down close to my computer and a power bar. I placed the MJ+ flat on the pan (couldn't put it in the center as the USB cable is too short), and gently put a large pot with a thick metal base on top of the MJ+.

-The short USB cable supplied with the MJ+ is just long enough to stretch between the power bar and the MJ+ on the upside down cake pan, with enough room for the pot to balance on top of the MJ+ without sliding off. A smaller pot would have no problem at all.

-As an aside, if someone did want to run their MJ+ plugged directly into the power adapter, this particular passive heat sink setup wouldn't work. The power adapter is thicker than the MJ+, so the MJ+ won't lie flat and a pot on top of the MJ+ will be at an angle and slide off . Putting a USB cable, which is thinner than a MJ+, between the power adapter and the MJ+ solves this problem.

-I just used spare pots and pans that were at hand. Both pan and pot have 10" diameters. Any flat metal surface in contact with the MJ+ will conduct heat away from it, cooling it down. The sides of the pan and pot act as cooling fins, increasing surface area and cooling ability. You could also use just one pot or pan, either laying the MJ+ on top of an upside down pot/pan, or putting a right side up pot/pan on top of the MJ+ as it lies on a desk or shelf.

-I received my MJ+ a week ago and will set this up more permanently in a while. I will use a longer USB cable so the MJ+ can be in the center of the pot and pan. Ideally I will somehow secure upper and lower pan/pot so I can hang the whole thing at the back of the shelf, out of the way, and where it will get more air circulation which helps with the cooling. I may get up the courage to take off the MJ+ casing and drill ventilation holes as LivinLarge posted above.

Would love to hear of any other passive cooling ideas (eg no cost once set up).

And a shout out to LivinLarge for the YouTube link showing a MJ+ being opened up.

No Problem DeepYellow, Just trying to come up with different ideas. And In order to make my vented cover I just took of the one side of my MagicJack Plus . The plastic cover on the side that has the word "magicJack " on it. it just pops right off its only stuck on with double stick tape. I just took it off took a piece of flat plastic ,traced out my original cover cut and new cover and used a paper punch and punched out about 20 holes. Anyway well keep the ideas coming. Right now I have mine plugged into an electrical out let ,no USB extension, and turned my fan off. And its been working fine for the past few weeks. 3 hour + conversations no drop offs. Well see how long this lasts.

Hi LivinLarge,

Thanks for the detailed step-by-step description of your cooling solution, and how it's working out for you.

The MJ+ plugged directly into the power adapter seems to be the hottest configuration, so it's impressive your device is running without any problems such as dropped calls.

The thing that had been holding me back from ventilating the MJ+ case was voiding the warranty and losing the ability to return the MJ+ for a replacement if it was defective. But if your holes are only in the copy of the plastic cover, the original cover could be put back on if the unit failed, and so sent back.

What do you think of the idea of just removing the cover and leaving the top of the case open?

Take care,

DY

Ok, DeepYellow..I think for our BETA testing (lol)this will work fine..as long as your not in a damp or very humid location. Ya, just pop the cover right off .And see how it goes.

Just for you all information, when I called Magic Jack customer support and told them my Magic Jack Plus was overheating, they sent me a new one and DID NOT WANT THE OLD ONE BACK.....So don't worry about voiding any warranty or punching holes in the case.

Livin Large,
I was SHOCKED that they did not want the old one back, they sent me everything, the USB cable, power adapter, Magic Jack Plus, I've still got the old original Magic Jack plus and all the things that went with it. All Magic Jack wanted was $9.95 for shipping.......

Thanks you guys.Thats one of the first things I noticed about the magic jack was how HOT it was....so

After reading this i decided to get an exacto blade and pop the front plate off my magic jack. I then got a plastic lid from strawberries and cut it to the size of the magic jack.. I then poped 10-15 holes in the plastic top with a paper holr punch and then taped it back into the place the "magic Jack faceplate" sat. I obviously kept the magic jack faceplate so i can make it "original" at anytime.

I will report back on how it works ...

I also wanted to add I have been thinking maybe its a static build up in the magic jack itself? And I was thinking if you put the magic jack on a powerbar with a timer and have it shut off even for only a few minutes in the middle of the night... if that would work... its just a guess.

Any updates on the guys for this thread? Love to hear them if you do.

I agree 100% my Magic jack been working perfect since I poped the front "faceplate" off of it. I think it was a major design flaw to not have any heat vents built into the magic jack, no wonder so many bad reviews it took me a long time to figure out the problem (thanks to this thread)

Denny does your magic jack now work pretty much perfectly? if so how long?

Most recently I've had a few drop offs , but I think what is happening in this case my internet connection is faulty. I don't seem to have many problems, but if it rains outside I have more drop calls. Must be getting a small surge and then disconnects, and then i have to flush the router and modem. Then it works fine. But I'm thinking a lot of my MJ problems are probably faulty cable connection problems. Well be looking into that idea. I don't have much rain here so... But MJ temperature seems to be fine

PostPosted: Sun Feb 10, 2013 2:29 am    Post subject: My Magic Jack Flashing blue light

My MJ plus was acting strange today. Dropping off a few times. Sounded like a FAX machine was running in backgound a couple times. Wouldn't hold a dial tone. But if you tried enough times the call would finally go through. Now it is just flashing a blue light. and it will only work if i plug it into my computer. I double checked connections, power source all seem to be fine. Hey Denny2 , if i tell them my MJ is overheating will that come with a new receptacle to USB adapter or will it only come with the MagicJack? Also my MJ plus is over a year old will they still cover it?

Hey "Livin Large", the Magic Jack has a lifetime warranty, just go to their customer help text thing and tell them you want a new one because of overheating issues..
I don't think it's the power adapter messing up.
They will charge you $9.95 for shipping and you get the whole kit.

Thanks for your help Denny2 and here is what I got when I went to MagicJack Live help:

Is the blue light on the front of your magicJack PLUS blinking or solid when plugged into the power adapter?
Solid
Blinking

Request a FREE replacement power adapter by CLICKING HERE
ok

And I try to go back into tech chat and I only get : you do not need to speak with a tech if you have a blue blinking MagicJack, request for free power adapter. So I did. This must be a big problem for these guys.Im going to see how well my MJplus works just plugged into my computer. I usually don't have it plugged in to it. So If it works ok Ill settle for the free power adapter. If it doesn't Ill be getting back on with them

Item Description Qty Price Each Total Price Charge Date

OK, my new power adapter arrived ( took approx 4 days) . MJ plus with new adapter working fine. Actually I have been using the MagicJack Plus plugged into my computer this week. I have found the connections never dropped off and the voice quality sounded as good as a land line connection. Ill be checking the temperatures of the new adapter with the MJ+ attached.

Since I have poped off my faceplate , I have had very few issues... I still drop once and awhile (but all my friends and family know about it already, so they just call me back) OR Ill hear the odd weird beep on my end.. but its so rare i really dont care.

Again thanks denny.

Mayo: that is exactly how it works for me too. My friends and family know if it drops off, its my MagicJack. We call it " MagicJack Dropoff". But if I get too frustrated and if there are too many drop calls I will plug it into the computer itself. Fortunately its been working pretty well. I have my face plate popped off too. I just blow the dust out if I see it getting some built-up.

It's been close to two years now that I bought the MJ+, and it has never worked correctly on my Linksys Router, nor directly connected to my cable modem either when used alone. The blue light has never flashed, and it does get quite warm but not hot.

It only works almost flawlessly when connected to my computer. I do get the occasional disconnect, but that's it.

So I paid extra for the MJ+ and could never get my money's worth because I have to use it as a regular MJ.

I contacted technical support chat dozens of times, and they tried dozens of things to get it working right, but to no avail.

It works, but I have choppy sound that comes in "waves". I can talk for 10 minutes with no problems, then, 30 seconds of choppiness, then another 5 minutes of perfect sound, then another 30 secondes of choppiness...

Connected to the computer (which accesses the internet via Wifi) no problems whatsoever. I've come to the conclusion that MJ+ is an underpowered ARM processor crappy product. The network is also "underpowered" with not enough available "lines" causing occasional time-sharing drop-offs .

The blue light should NOT blink - there is a tiny little white light behind/to one side of the blue light, this little white light should blink, almost in unison with the blinking orange/amber light.
Have never had any "big" problems with my MJ+, by it's own or connected to the pc.

I don't know about the rest of you all, but I followed the directions from this Forum and got into the settings of the wireless router and opened up some ports specifically for MagicJack Plus to use. It seem to help. I assumed everyone else has already done this. If you haven't done it you should IMO

I'm confused. Exactly how did making tweaks to your router cause your MJ+'s power supply to become strong enough to do its job?

This has nothing to do with the power supply.
It has helped me with dropoffs. But this maybe different results for different people. MagicJack Plus is ever evolving. And we are the guinea pigs.

I'm a newbie and must say that I love this form. I've got a ton of good information from you guys. I'm quite sure that I have a heat problem but it's not with dropped calls. After I've been on the phone for a half hour so I get kind of garbled sound kinda like bad cell phone reception area. After reading what you guys been trying I'm definitely gonna use the extended cable and split the case open on my magicJack. I'm going to try going step beyond that. I'm gonna use an USB adapter that comes from like a cigarette lighter/power port outlet that you power a lot of your USB voltage type devices in your car. I have an adapter that plugs into wall/AC and it converts to a cigarette lighter so I can plug my USB plug right into then go with the extended cable into the magicJack. What do you think? Any thoughts?

I wouldn't bother with the "cigarette lighter adapter" business at all. Just use the mj's own a.c. adapter, but connect it to the mj+ via the included usb extension cable. All you're looking to do here is to get the device out of direct physical contact from the a.c. adapter.

Anyway, I'd first try just that alone. If it doesn't fix the problem then open up the case.

But it sounds to me like the issue may very well be with your ISP and/or your router. If you have a router that's separate from the modem (not a combined modem/router unit), try (temporarily, just for testing purposes) disconnecting the router from the modem and connecting the mj+ directly to the modem and see if that corrects the problem; if it does, chances are the problem's with your router's hardware, firmware and/or settings.

I am using the extension cable with the cigarette adapter. The heat at the MJ+ has dropped noticeably. I had one extended conversation just tonight and had no garbled sound. So far so good. Thanks for your follow up. Think that as an added precaution that I will split open the case.

Sounds promising!

I don't see how using a cigarette lighter contraption (vs. the mj's a.c. adapter coupled with the USB extension cable) would make any difference (unless you received a defective a.c. adapter or it somehow went bad), but it certainly doesn't hurt the mj+ as long as its voltage and wattage output are the right amount and consistently so.

BTW - MJ has been offering consumers one free replacement a.c. adapter per mj+ device, so I guess some of those a.c. adapters have indeed proved to be defective. And plenty of folks have also been successful at using other a.c. adapers with the mj+.

My bad......kinda! Previous posts had suggested that the power adapter provided by MJ did run hot. So just to eliminate that possibility, I did try my "cigarette plug" adapter. Since then I have plugged in the MJ adapter by itself to see how much heat that it generate. The MJ power adapter did not seem hot at all. I may try it with some sort of component plugged into it, so as to see if it runs hot under load.

Like I said, now I was using the extension cable provided by MJ and the heat is noticeably cooler and the garbled audio has went away.....at least during my first long conversation. I able pretty much convinced that MJ+ problems are due to heat. I intend to split the case so that the internal components are better able to cool.

Thanks

Good To Know I'm Not The Only One Having This Issue.
We Have Been Having Issues With People Saying They Tried Calling Myself Or My Wife, To Which We Both Would Reply Nope The Phone Never Rang. We Would Have A Dial tone But When You Tried Calling Someone Nothing Would Happen.
So I Was Almost To The Point Of Going Out And Buying A New Cordless Phone Until I Came Home Today And Could Smell The Scent Of Very Hot Electronics. Come To Find Out It Was The Magic Jack.
It Was So Hot When I Separated The Power Adapter From The Unit That I Dropped It As It Was Too Hot To Hold.
As Per Responses In Here I Have Hooked It Back Up Using The Usb Extension On The Computer Instead Of The Power Adapter.
Problem Resolved

All I Can Say Is Im Glad That I Found This Out Now...As I Could See Our Son Knocking Some Papers Off The Desk Onto The Unit And Starting A Fire.

- It may also be that your MJ+ a.c. adapter is shot. You should be able to get one replacement for free from MJ - suggest you do a live help chat to request one. Then use the usb extension to connect the two together.

Certainly my experience with the new MagicJack Plus and the new new 2014 version I just got, they get really hot because that's what they do. I should certainly never have to pay $9.95 to replace their crappy design for them, it's not even worth that much when it heats up like that! When the chips heat up so much even when still working, they will wear out sooner.

Yes It Got That Hot
If it's too hot to touch, it becomes a safety issue. Was the AC adapter melting, smoking or baking itself to the point that it started to crack apart? In any case, I hope you're not using it anymore.

PostPosted: Mon Sep 16, 2013 1:58 pm    Post subject: getting hot

Running mine MJ+ now a few months after i got the free USB power adapter. MJ+ seemed to be working a little better for a while. Then I had not check the temp of my mj+ in months and i thought I better check it see how its doing. Well it just about burned my hand when I touched it. Calls were dropping off a lot more. So I run my fan on it to cool it down. Then one of my buddies that call me weekly told me between each ring he was getting a MagicJack advertisement. For each ring he got another ad. So this pissed me off so I plugged it into the USB on the comp and the commercials stopped. And the drop offs were a lot less. Yesterday I had enough I chatted with MJ tech and told him I need a replacement. So they are sending me a replacement for 11.80 . I will see how well this new works when I get it. Seems as though they are still trying to figure out all the bugs in MJ......at our expense. To be continued.......

Perhaps there was a glitch in the power regulation circuitry on the first one you recieved. I'm glad your second one seems to be working more appropriately.

the rest of the magic jack gets warm,the part that plugs into adapter gets hot.i am thinking it has something to do with all adapters or there is a faulty power supply(or inadequate).maybe there newest one does not overheat,i have magic jack plus 2014.i guess magic jack company does not want to admit about overheating issues.

Another thought - I see the MJ included ac/usb adaptor has a 1 amp output. That, I believe is much higher than the typical cpu usb output.

Why not substitute an adaptor that has a lower current output, like .5 amp? Wouldn't that reduce the heat being generated?

I'll see if I can find one and try it out. JC


The Amp Rating of an adapter doesn't mean it's pushing out that much current all the time.
It's just how much current can be drawn from (sucked out) of it, without it getting damaged.
Don't feel bad about not knowing this. I too use to think this same thing, many years ago, before I learned electronics. Smile

I also wanted to say, the adapter you choose is important. Exclamation

If it's a really cheap type, made poorly, it may even ADD noise or interference to the circuit it's connected to, or may even cause damage to that circuit because of spike-voltages within the cheap adapter, if it's not filtered properly, or it's designed poorly.

I just looked at my iPad2 power adapter and it says it gives 5.1 volts DC and can support up to 2.1 Amps being drawn from it.
So, the Apple iPad adapter is a good choice to use if your original MagicJack-Plus adapter screws-up. Smile

I also saw an article from someone who opened the iPad adapter, and showed how it's made.
It looked very good inside, with special added circuitry to stabilize the voltage / current and it's filtered very well too.

They showed waveforms from several others, and the Apple one.
Apple gave much less ripple-voltage, and no spike voltages.

http://www.righto.com/2012/05/apple-iphone-charger-teardown-quality.html

It's possible the MagicJack-Plus adapter may be causing some issues with voice quality for some people, or dropped-call issues.

Just a thought. Wink

PostPosted: Sun Aug 03, 2014 7:19 pm    Post subject: 2 outputs - 1 AMP and 2.1 AMP charging at the same time :)

****EDITED****
Much to my surprise, this company no longer lists the adapter for sale.
The fact is still true though... regarding the adapter chosen,
...about it making a difference with circuit operation.
It just means you need to find another company selling a quality adapter.

I eMailed the company and was told they're working on another adapter/charger
That's why the one called "Fuel" is no longer showing on their site.

There's no word from them when it will be done, and what specs the new one will have.

------------------------

Hey...looking around the internet, I found the ideal replacement adapter for your MagicJack Plus.

This one has Two USB connection outputs (total of 3.1 AMPS)

One of them is a 1 AMP output, and the other is a 2.1 AMP output.

So, this means you can power your MagicJack Plus, with the 1 AMP,
AND charge your iPhone, or iPad with the 2.1 AMP, at the same time.

It looks like it's made with quality circuitry, as the Apple product is.
No spike voltages, and fully regulated for voltage and current.

They also give you an option to order it with, or without, the USB Data cable, with the original 30-pin or the new Lightning connector.

http://phonedoctors.com/product/fuel-by-phone-doctors-3-1-amp-dual-usb-home-charger/

Right now, at the time of this post, it's on sale. Around $18 without the cable.
(normally $25.00 without any cable)

There's also a LIFETIME warranty on the adapter.

They also repair all types of phones, and sell the DIY parts too.

This isn't an advertisement for them. Smile I just happened to see it, looking around the internet for adapters similar to the Apple version.

I've been looking for a place like this, for a LONG time.
Rather than purchasing from China, ...not knowing what the quality will be.

I hope I've helped someone with this.

PostPosted: Fri Oct 24, 2014 5:17 am    Post subject: Tests on knock-offs and Original power adapters, comparisons

This is why some power adapters are not good choices for the MagicJack Plus

Ken Shirriff's blog has an article where 12 power adapters were tested,
including Apple's and the cheap knock-offs.

http://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html

You'll see how bad adapters can create noise on your phone-line or other
issues, using it with the MagicJack Plus, or even using a crapy adapter to
charge your phone or tablet, or view it.

There's oscilloscope photos, and technical stuff that's explained very well.

It will give you an eye-full.... Smile

I've been using my Logitech adapter (one of the ones that came with my Logitech MX performance mice) and it solved the issues that I had with my MagicJack + (which was that the MJ+ wouldn't allow outgoing calls, I'd press the number buttons on my phone but the MJ+ unit would not take them as being dialed).

I'm not sure whether it puts out less amperage than the stock MJ+ adapter or not, but for me, the MJ+ has never gotten hot, of course mine is a 2013 product so maybe they made changes to it since the OP posted about his trouble of it getting hot, or perhaps he had a defective unit in some way.

Never the less, my Logitech mouse charging adapter has worked fine with my MJ+ since June of this year.

That's amazing..!
I guess that articles point has just been proven.

I bet most of the trouble issues posted on this site can be fixed by using a better quality adapter.
And the one given with the MagicJack Plus is most-likely causing many, if not most, problems experienced by customers over the years..! Smile
