DOUBLES the battery life of the MP3450i!

This is the Tekkeon MP3450i "R3" version, which includes a USB port, allowing you to power/charge virtually ANY device that can be powered by USB! It also features a more stable Li-Ion battery. Other retailers are still selling the older model, which does NOT include the USB port and uses a polymer battery. The MP3450i R3 is otherwise identical to the original version

The Tekkeon myPower 3450i was developed with input from Cradlepoint Technologies engineering staff to be the best portable power source for use with 3G and 4G routers. It is an industrial-grade, high-temperature, high-capacity lithium polymer battery for use with portable instruments and equipment as portable power, or as an Uninterruptable Power Supply (UPS) for battery backup. The MP3450i can be used to power and/or charge any device that requires between 5 and 19V, plus a second 5V device like a smart/mobile phone, iPad® or iPod® via USB. The voltage is fixed for the connected equipment, or can be quickly changed to meet the power needs of a wide range of devices.

The 3450i comes with DC adapters/tips for use with a wide variety of products, including 3G & 4G routers (Cradlepoint**, Peplink/Pepwave, etc), and its USB port allows you to also power/charge virtually any 5V USB-powered device!

How long can the MP3450i R3 power my device? Below are estimates for how long the MP3450i R3 can power a variety of devices*:

  • Cradlepoint MBR1400/MBR1200B/MBR95/CBA750/CBR400/CBR450/IBR600**/IBR650**: 12 hours
  • Cradlepoint PHS300/CTR350/CTR500/CBA250: 16 hours
  • Apple iPad: 10 hours
  • MiFi/Jetpack Hotspots: 15-35 hours
  • PDAs/Smartphones (iPhone, Blackberry, etc): 16 hours
  • Cellphones: 70 hours (talk time)
  • Portable Media Players: 14 hours of video, 26 hours of audio
  • MP3 Players: 48 hours
  • Portable DVD Players: 7 hours
  • Camcorders: 4 hours
  • Laptops (except Mac): 4 hours

*actual time may vary. Always consult manual for voltage requirements. You can add the MP3450-10 expansion battery to the MP3450i and power your equipment for TWICE as long!

**to use this battery with the IBR600 or IBR650 or other 4-pin routers, you must purchase the 4-pin GPIO cable (sold separately)


  • Universal to power and/or charge laptops and hundreds of portable devices
  • Rechargeable lithium polymer battery provides power on the go for many devices
  • Includes adapters for connection to most major brands of portable devices **to use this battery with the IBR600 or IBR650 or other 4-pin routers, you must purchase the 4-pin GPIO cable (sold separately)
  • USB port to power virtually any 5V device that can be powered by USB (phones, iPhone, iPad, etc). If you are using the battery to power both a primary device and a USB device simultaneously, the battery will drain faster.
  • Extendable to double its battery capacity (MP3450-10 expansion battery sold separately)
  • Voltage lock holds current voltage setting
  • Visual indicators identify exact power level
  • Small and lightweight so it’s comfortable to carry
  • Can be charged by a solar panel (The solar panel can connect to the DC IN port or to the 6-Pin Input Port, depending on the type of solar panel. Charging the MP3450i efficiently requires a minimum of 1A current output from the solar panel. In general, a 25W or higher solar panel should provide sufficient power to charge the MP3450i)

All as expected, prompt delivery, no bad surprises.

This is an excellent way to power the Pepwave MAX mobile router when no AC power is available, will work great in a backpack type setup. I used this together with the Extended Battery and I got just over 9 hours run-time powering the MAX 700 with two Pantech UML290 USB modems running on the VZW LTE network. The voltage should be set to 19V and the correct plug-in tip is "B".

The power supply on this thing is more bulky then the one for my laptop. It really cuts down on the portability of this unit. However, I'd still recommend this for anyone. The flexibility of output voltage, the USB port, and the run time of the battery makes for a great a tool for any box/bag.

The Tekkeon Battery Pack works as advertised. I've used it eight to ten hours a day with Internet Radio and still haven't used 50% yet. Have used it with the Cradlepoint Mobile Router (CBR400) and it's just what I had hoped for when I bought the CBR400. A great product. Thanks, Keith Peirson

This unit works flawlessly and when coupled with the extended battery, the power seems to go on forever. There seems to be a tip for almost everything. I highly recommend this unit!

Excellent battery. I also purchased the extended pack, and the combination makes for a week's worth of charges for an Evo 4g. Nicely powers my 12v bluetooth speaker with juice leftover too. Worth the money, and this website is speedy and reliable.

Item arrived speedily from the 3G Store. The Tekkeon MP3450c works well as advertised. Configuring the Tekkeon for use with my Cradelpoint MBR router was a snap with the helpful configuration sheet sent by the 3G Store for my specific router. I plan to buy the extra battery that can be added onto the system. I wonder who can supply the solar power device which can plug into the Tekkeon MP3450i?

Read the instructions carefully so as to take best care of the battery. Bought this to extend the battery life of my laptop while out on consulting gigs and to power a CradlePoint CTR35 when needed. It also powers many other peripherals I have such as iPod, iPhone, BlackBerry, Sony PSP, etc. Powered everything pretty much out of the box except my laptop and wife's laptop. Had to spend another $5 on connectors to get those working. Simple to use, lightweight, and effective.

I bought this with the sole purpose of powering & charging a mifi2200 mobile hotspot. The battery pack works very well and even lets me charge my Ipad in a pinch. I am happy with this purchase.

Questions & Answers

How can I order the cable to attach the GPIO port of the Tekkeon to the Cradlepoint CBR400?
Is there a USB cable that will power the CradlePoint COR IBR600? I want to use a different battery pack that has a USB port.
Does this work with the Pepwave Max On-The-Go with Load Balancing & Speedfusion and how long would it last with the extended battery pack?
