The Neo FreeRunner and the Neo 1973 can be charged with the supplied USB charger, which is a device that does not comply with the recent USB Battery Charging Specification. This specification demands for an open circuit on the ID pin and a short circuit between the D+ and D- pins.

Most of the USB chargers around behave the same way as the one supplied with the Openmoko Neo. In fact, up to now no charger has been identified to comply to the specification mentioned above. The differences (incompatibilities) result from the way the USB charger signals the mobile phone that it is present: most of the manufacturers chose to connect a resistor between the "ID" pin and the "GND" pin in the USB connector.

For Openmoko Neo, the value of the resistor is 47.5 kOhms.

AKII Technology Charger (supplied with Neo FreeRunner)

This charger comes with the Neo FreeRunner package.

Specifications

  • Model: A10P1-05MP
  • Input: 100-240V~ /0.3A
  • Output: +5v up to 2.0A
  • Signaling: 47.5k 1% resistor between ID pin and ground for openmoko charger identification

Compatibility

  • HTC Polaris (tested on O2 Xda Orbit 2)
  • Openmoko Neo1973

Blackberry PSM05R-050CHW

P1040112.jpg

Specifications

  • Model: PSM05R-050CHW
  • Output: DC 5 V - 0.5 A

Compatibility

  • Openmoko Neo FreeRunner, provided the 500 mA charging mode is enabled on the FR (see Forcing_fast_charge_mode), as otherwise it would only (dis)charge, as the FR would only draw 100 mA out of it.

Compatibility

  • TomTom navigation devices
  • Openmoko Neo FreeRunner (just plug in, it will charge with 1000mA without forcing fast charge!)
