TekCharge MP1550 FAQ

Using TekCharge MP1550
General Information


1. Will TekCharge MP1550 work with my device?

TekCharge MP1550 works with hundreds of personal electronic devices. For a list of compatible devices, go to: TekCharge MP1550 Compatibility

The MP1550 is compatible with devices that require less than 800 mA. Due to the increased output required by many smartphones (such as Droid, Evo and Nexus) the MP1550 must not be used to power or charge these phones. The TekCharge MP1860A, however, is ideal for these phones.

2. If my device is not listed on the compatibility list, will it work with TekCharge MP1550?

TekCharge MP1550 works with most devices that require 5V. The compatibility obstacle for TekCharge MP1550 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 MP1550 cable to the device, or you can use your USB device cable in place of the adapter.

The adapters that fit a majority of the jack types are included with TekCharge MP1550. However, if you cannot find your specific model in the compatibility list, but see similar models, it is likely that TekCharge MP1550 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. Several of the most common adapters are included with TekCharge MP1550. If your other devices require different adapters, you simply remove one adapter and replace it with the second adapter. Most adapters not included with TekCharge MP1550 can be purchased through the Tekkeon online store.

5. Can I obtain adapters that are not included with the TekCharge MP1550?
  Yes. For a nominal fee, you can purchase additional adapters from the Tekkeon online store.
