TekCharge MP2250 FAQ

Using TekCharge MP2250
General Information


1. Will TekCharge MP2250 work with my device?
  TekCharge MP2250 has been specially designed to mount to and power CradlePoint travel routers CTR350, CTR500, and PHS300. The battery also will power other travel routers and 5V devices. For a list of compatible devices, go to: TekCharge MP2250 Compatibility

2. If my device is not listed on the compatibility list, will it work with TekCharge MP2250?

TekCharge MP2250 works with most devices that require 5V. The compatibility obstacle for TekCharge MP2250 is the physical connection to the power jack. Device manufacturers all use varying types of jacks, so an adapter must be used to connect the TekCharge MP2250 cable to the device.

If you cannot find your specific model in the compatibility list, but see similar models, it is likely that TekCharge MP2250 will work with your device. You can assume that the model has not been included in the compatibility list, as we have not yet identified the adapter type on that specific device.

Tekkeon makes every effort to identify the adapter plug requirements of new devices. However, due to the large number of devices available, we are not able to identify the adapter requirements for every device.


3. How do I know which adapter to use with my device?
  The size of each adapter plug varies to match the device. To determine which adapter to use, connect each of the included adapters to your device. The correct adapter will fit securely.

4. Will the same adapter work for all my devices?
  The type of adapter required depends on the device. When devices require different adapters, you simply remove one adapter and replace it with the second adapter. Most adapters can be purchased through the Tekkeon online store.
