Call Tekkeon support and let them know. I am pretty sure there is nothing they will be able to do, BUT my recommendation is to make sure you ALWAYS plug the power cable to the battery first before plugging in the end connector to the CTR350 router. Even their manual states that.

Good luck.

There has been a few Cradlepoints that have went up in smoke. The common denominator has been the new Tekkeon MP3450, seems the the MP 3300 and MP3400 have not been a issue. What model Tekkeon did you use to lose your Cradlepoint.

For a guy that gets so excited I did not read all the instructions

#1 check polarity DONE
#2 determine and adjust voltage Done
Plugged in and FRIED.... Done
#3 Lock voltage ..... hmm little late.
Actually it recommends 1 volt over the required voltage too.. now that is strange but I missed that too.

probaly my fault but boy am I scared to plug in my $3,000 tablets and risk frying them too.

Well guess I am getting the new Cradlepoint with battery model as soon as they ship. Will talk to them on Monday

I do like the Tekkeon size for a laptop backup. Hope it was jsut my fault.. think they could put :LARGE red notice LOCK voltage befoer plugging in.

But then again some of us would charge ahead anyhow.

Pounding head on table and crying in my beer. Sad Crying or Very sad

APC puts a yellow sticker over the proper ac plugs on its battery backups giving the instructions, etc. Users typically leave that sticker where it is and plug the computers into the surge protector outlets causing no battery backup protection.

After moving things about in my client's office and unplugging the cords in the apc backup, the new Windows consultant plugged the computers into the surge protection and the clock, calculator and phone charger into the battery backup outlets.

I did the same recently with my Tekkeon MP3300. I made sure to use the correct tip, plugged in the cable to the Tekkeon, adjusted the voltage to 5V, set it to hold then plugged in to the router. The router lights flashed briefly then I got a whiff of something burning. Router is now dead.

I called both Tekkeon and Cradlepoint. Neither would accept any responsibility. Cradlepoint asked me to send them the router and the Tekkeon and they would test it out but basically told me they since I used something other than their AC adapter to power the unit I was on my own.

Since I had no warranty on the thing I opened it to see if there was a fusible link or anything user replaceable but didn't find anything.

Now I'm afraid to try to use my Tekkeon with any of my other electronic gadgets!

I surely thought I did every thing right.
they say the ONLY have center positive post so that checks with
the adapter with the yellow center.

and ok so I set it to 5 volts where as the instructions say to set it one voltage higher.

and poof .. thank GOD it did not fry my USB720 modem.. its light stayed on`adn it still works. So the voltage reaching the USB720 is enough to run the modem.. hmmmm they seem to have better protection than cradlepoint

after 3 seconds I unplugged it and then tested 2 or 3 more times but definetly had a smell of fried electronics so I knew it was dead

before i try this battery on any EXPENSIVE equipment i plan to go to radio shack and test or buy a tester to confirm voltage.

Cradle point needs to test a voltage range to determine the fry thresholds and let us know.. eg 4.7 volts fry 7.2 volts fry middle range is fine. or build in more protection.

Question: the amount of amps , as long as it is higher should not make a difference should it?

I would assume as a battery wears down and the amps are not there you would think it just shuts off


I left tech support message with cradlepoint yesterday .. still not heard back, but from what you are telling me ?? it is not fixable??
I was going to mail it to them but if there is no repair option then why bother

I ordered a new one with the battery ?PSH300, but apparently they are now shipping from Taiwan on Dec 14 and shippable on the 20th.
I offered to fly to Taiwan to pick it up if I could get a discount. LOL Very Happy

I didn't ask Cradlepoint how much they would charge to repair it or even IF they would repair it so you might ask them that. When I opened it up I was looking to see if I could repair it easily myself.

The device being powered determines how much current will flow so the fact that a power supply can supply more current than is needed is irrelevant. However, if a higher voltage is applied then more current will flow. I suspect somehow the Tekkeon delivered a voltage spike.

I'm curious, when you connect the router to the Tekkeon, do you have the USB modem plugged in or do you plug in the modem after connection to the Tekkeon? I'm pretty sure that I had the modem plugged in first.

I have been using the Tekkeon 3450 with the CTR350 almost every days for 8-10 hours a day with no issues. I plug the fat round connector to the Tekkeon first, then I connect the yellow end connector (already plugged into the spiral battery cable) into the router. Also I already have the USB modem attached to the router prior to any cable being connected. BUT that should not matter since I have hot unplugged and plugged the USB modem many times while the router was being powered with NO issues at all.

Once I have the router powered I put it into my bag and off to work I go for the whole day, never touching the setup till I come home at night. This has been working me like this for the last month or so.

Also I have the USB switch always set to the unlock/off position so I am not draining any battery power. I have never had any issues with the buttons being pressed since the router sits on top of the battery pack. Also when you unplug the power cables the battery pack resets itself ALWAYS back down to 5v so you never have to change any voltage settings.

I hope the above steps help.


Good luck.

Yup, I fried one of my 350's today as well Sad

I have read several posts on the internet about frying the 350 with the Tekkeon, some by a frequent poster here.

To get around the problem, I spliced a USB cable to an 350 compatible adapter, and always plug into the USB port of the Tekkeon, so the 350 always gets only 5V, and never gets surged (and as a bonus, it leaves the main cable to the Tekkeon available to charge and power other stuff.

Today, I left my little makeshift the cable at the house, and had to plug up to the main cable. I must have plugged it up in reverse order, and smoked my little CTR-350.

Gotta go order another one!

Ok Joe

What am I learning here?
pluggin in with the Tekkeon cable gives it a jolt and the Tekkeon USB cable signal doesn't??

I now have the newer one psh300 with the battery included but have not tried teh Tekkeon out yet. Too Scared too.

I would rather buy another spare battery for the unit than connect to the Tekkeon
and risk frying it again.

By the way does your battery pack havea yellow center, I went to radio shack and testing the voltage, it does say 5.25 volts on the 5 volt setting and center is positive, or that what the EXPERT thought at the radio shack?

Was gonna ask the cradlepoint guys to test this out to determine if it will work first.

Hoping they support the product for us guys that need more battery time.

I have the Tekkeon MP3300 which doesn't offer the USB port. Since I fried 1 CTR350 with the Tekkeon I am afraid to ever try it again. I have resorted to setting my Tekkeon to 12V and plugging in a 40W inverter (12VDC to 120VAC), then plugging in the CTR350 AC adapter. This is certainly not the most efficient way to do things but it seems to isolate the CTR350 from the Tekkeon so that I can use the Tekkeon for power.
