Many fans of EVDOforums know that we've been looking for an "external battery pack" that we would be comfortable selling for use with the 3G routers we sell. That search is over.

Effective immediately 3Gstore.com is the exclusive U.S. vendor for a new battery pack that Tekkeon has not even announced yet -- the Tekkeon myPower MP3450i


(picture shows MP3450i powering a CTR500)

This thing is more powerful than anything Tekkeon has ever made and it will power the portable Cradlepoint routers for up to SIXTEEN HOURS, and power the home/office routers like the MBR1000, KR2 or Linksys for up to TWELVE HOURS!

We've got a complete review online right now at:

http://www.EVDOinfo.com/MP3450i

You can order the MP3450i from 3Gstore right now -- our first shipment is scheduled to arrive Wednesday - Jan. 27 2009

I have successfully used 6 different battery solutions with the CRT500. One of the most difficult issues I've found with universal battery packs is that tips supplied with the batteries usually don't fit the CTR500 power jack correctly. They are either too loose or seem not to be deep enough. The end result is that slight movement can cause the router to temporarily loose power and reboot.

My ultimate solution was to make my own cable out of a USB power adapter and the the end cut off of a CradlePoint car adapter. Unfortunately this isn't elegant and because both use a straight connector (rather than an L-shaped adapter), it extended the size of the solution and made it too easy to accidentally break the adapter if accidentally hit.

Have you tested the connection quality with the provided tips and the DC in jack on the router? Do they hold securely?

at no point in time did the plug give me issues with CTR500.
i wasn't exactly being gentle with it, but i was not throwing my CTR500 around to test the fit of DC jack, either.

I have several Tekkeon 3450's. They are really nice, and I have learned to do a lot with them. They have replaced about 40lbs of adapters, chargers and power bricks when we travel.

A few suggestions (if I may).

For any of the 5 volt CradlePoint routers, make a USB2CradlePoint power cable. Don't use the cord and tips. Sure, they fixed the old problem of burning up the routers, however, human error comes into play, as you will burn up a CradlePoint (and perhaps the Tekkeon) the first time you get the voltage wrong. Then, always use the USB2CradlePoint cable for powering the 5 volt CradlePoint routers.

The MBR1000 does not always seem to like the 3450. I have seen two of mine just boot up and just flash all the lights on and off. Sometimes it works, sometimes it does not. I don't recommend it.

I ordered power tips for everything we have that runs off of DC, and when Tekkeon did not have a tip, we made our own cables. It's a sweet, sweet deal.

All of our Laptops have 19 volt power bricks, and our big ones are 90 watts. We either made or ordered connectors so that the power bricks will work with any of our laptops, plus charge the Tekkeon. In short, one power brick, many uses.

The 3450 is great for allowing you to swap out batteries in a laptop (or anything else for that matter).

The USB port on the 3450 can provide more power than the 250mw standard USB port. If you are carefull about what you hook up to the USB port, you can make USB splitter cables (a squid) to power more than one device at a time Smile

They also work great for powering 2.5 inch hard drives.

Joe, the item we are selling is not the same as you have.

ours is the MP3450i that has more battery power than 3450 and dipswitches that make it much harder to fry a router accidentally.

to add the dipswitches, they removed the USB port you mention.

for "tech-savvy" users like yourself, the 3450 is a good option and we considered selling it but didn't like how easy it was to change voltage setting accidentally.

because of support concerns, we're better off selling the new MP3450i

Joe how long does your laptop last when you use the Tekkeon??? I think it would be a great power backup in case of a storm or power outage.

Is there a pre-made USB to Cradlepoint tip that one can buy for the MP3450?

I like the idea of locking the voltage in but the regular MP3450 is $120 vs. $200 for the MP3450i. Just trying to conserve $$s!

Thanks. D

Yes, I understand that.

I disagree. The 3450 (non-i) changes voltage only when unlocked. It's still a matter of human error. If you dip switch the voltage to charge something with a higher voltage, then plug it it a 5v CradlePoint, it will still fry the router, so whats the real difference?

I notice that unlike the 3450, your unit also does not have the voltmeter markings for the lights. This is yet another point for voltage setting failure. Combine the covered (and hard to understand) dip switches with the lack of a voltmeter, almost assures that users are going to burn up equipment (unless they use it only for the router, and nothing else - and in that case, it becomes just a very expensive and overpriced aux battery pack).

Alex wrote:

Yes, unless you are only powering a router, the new one is much less functional, and much less useful.

I would think you would be better off selling both units (and a USB to CradlePoint cable), and let your customers make the choice. But you know your situation better than I do, and if you are worried about the "tech-savvy-ness" of your customers, I certainly understand.

On the other hand, if I purchased an [expensive] "3450-i" unit from 3G, then found out their was a better unit for my situation, I might not be very pleased.

I guess like purchasing anything, the buyer should always surf around to educate themselves as to the options available to them, for the situation.

I have to say, I just ran this by our folks here, that use the 3450's with CradlePoint routers on a daily basis. In a 5 to 0 vote, we all agreed that the 3450-i usefullness was degraded to the point of only being useful to power a single device, and if used to power other devices at other voltages, it was far more likely to burn up equipment.

We found that using dip switches to set the voltages was difficult to understand, coupled with the lack of a USB port made the unit basically unsuitable for a road warrier.

Since you are marketing the device for use with a mobile router that is used by road warriers, it seems the 3450-i would be a poor choice for your target audience.

We feel that a better solution would be either a USB to CradlePoint cable, or a 3450 MainCable that contained over voltage protection for the "known to be overly voltage sensitive" CradlePoint units.

So there ya go... the opinions of 5 of your folks that actually use this stuff on the road and outside of a sales/support/testing center.

As far as the "tech-savvy-ness" of the group, its worth noting that two of the five are actually responsible for setting up the 3450's at the right voltages for the purpose at hand (usually for the other three), and they are not very "tech-savvy" at all. The other three are very "tech-savvy".

It is also worth noting that the only one of us who has burnt up CradlePoint routers with the 3450's by pluggin them up wrong, is your truly (and also the most "tech-savvy" of the bunch).

It is also worth noting that the 3G store's sales has directly benefited from 2 out of 3 of those burn ups Smile

Our goal isn't to have people fry routers, so they have to buy more.

We want to make it as "dummy proof" as possible, which is why we will automatically set the dip switches when someone buys a router & 3450i at the same time - it will be plug and play.

This is only our first Tekkeon product that we are stocking - there may be more. This is perfect for the target use - battery backup for 3G routers.

Joe, I'm gonna guess that you didn't read our review. This part in particular is worth repeating in this thread:
Quote:
The Tekkeon MP3450i is a variant of the lesser expensive MP3450 and our customers are likely to ask us why they should get this more specialized MP3450i for use with their 3G routers. There are important reasons for that:
  • The MP3450i has a larger 58Wh battery (the 3450 has only 50Wh)
  • The engineers at Tekkeon and Cradlepoint discussed the power requirements and needs of the various routers to ensure that their products would meet all the required power needs. This means that Tekkeon is the first battery solution that has taken cradlepoint routers needs in mind to provide the best solution possible.
  • The use of dip switches on 3450i makes it harder for voltage to get "accidentally" set to wrong voltage.
That last point needs a bit of elaboration. On the older MP3450, the voltage setting was done using the same top button that displays the remaining battery level and if the unit's voltage was not locked, when a user meant to just check remaining battery level, they could inadvertently change voltage and fry a router! The use of dip switches on the MP3450i makes it impossible to accidentally change the voltage and that means it is far less likely to damage anything it is used to provide power to.

I've owned the MP3450 (like yours) for months now -- and we've taken the time to explain to our salesteam the important differences we see between that unit and the one we've chosen to sell.

If more of our customer's seem better suited to the MP3450, we're likely to add it to our product line in the future, but we think we have a pretty good feel for what our customers want sold and supported by 3Gstore.

I'll be adding this info to our review. Its something that we knew was in the works but could not be certain of until it actually happened.

Verbatim:
Quote:
CradlePoint will officially accept use of the Tekkeon MP3450i with our products and will continue to honor our warranty. This offer only applies to the MP3450i and will only be honored if used in the configurations shown in the following article. http://cradlepoint.com/knowledge-base/tekkeon-mp3450i
Please reference the correct model number in all documentation as no other battery is accepted or honored with the CradlePoint warranty


What this means is that (for now) 3Gstore is the only place in the USA that sells the only external battery pack that Cradlepoint endorses for use with their 3G routers.

Those who are interested in the Cradlepoint-endorsed and 3gstore-supported Tekkeon MP3450i can buy one by clicking here.

PostPosted: Thu Jan 29, 2009 5:58 pm    Post subject: Potential Tekkeon Battery Issue Reply with quote

I remembered my staff ordering a couple of Tekkeon battery packs a couple of weeks ago. As it turns out, I have both a Tekkeon MP3450 and MP3450i. I tried both of these with two CTR500 routers. I ran into a problem.

If I use a U722 (USB) card, in the router, it works fine. But if I use an Express Card (I tried two Novatel EX720's), it starts to power up and then shuts off. Then it tries powering on again. I tried two different EX720's on two different CTR500's using two different batteries (MP3450 & MP3450i) (yes, both batteries were properly set to 5v). I don't know if this means that the batteries can't provide enough current for the expresscard. I have no idea the current requirements for it, but it seems that this shouldn't be an issue.

Then I looked more closely at the picture on your site and it looks to me that you are using an EX720 and a USB modem at the same time. So . . . any ideas? Are there perhaps different hardware revisions of CTR500? What about the EX720?

So, I setup a few other battery packs (other 5V batteries) and most of them give me the same result. I have another type of battery pack that work fine with the combo though. But, they are much lower capacity than the Tekkeon.

Any ideas?

Yes, there have been at least two versions of EX720.
No, I don't think there have been hardware revisions of CTR500 (not sure)

But in that photo, I am pretty sure I was using a Verizon V740 with the Sprint U760.

In any case, I did not experience anything like you described.

Have you tested an EX720 internally at all? Most of my field staff have that model of card. I was thinking of this solution to be modified to be an in-vehicle battery backup solution for CTR500's. But this sort-of leaves me dead in the water. If you have one on hand to test, I'd appreciate it. I'd just like to know the card behaves consistently. I am going to get a couple more of our cards from work and test them today.

I am testing a CTR500 + EX720 with Tekkeon MP3450i and the combination is working without any issues.

If you purchased your CTR500 from 3Gstore.com, give our tech guys a call, there may be some things they can help with.
