The FreeRunner has three different [[Forcing_fast_charge_mode|charging modes]]: 100mA, 500mA and 1A. 100mA seems to be too low, as it is said, that the FreeRunner draws 100mA current even when it is switched off. A hub dynamo provides 500mA. If you want to use your lights while charging you need to connect the lights in series to the charger. At least the SON will increase the voltage and still delivers the same current. But you need a bypass circuit in case of less current draw of the charger when the battery is full.

Using an USB connection with that ID resistor for 1A mode provides the advantages that the charging mode is automatically correct.
 +
This might be important if you stop frequently and so cause some kind of power "disconnect" and you do not want
 +
to select the charge mode all the time. 1A mode does not harm the hub dynamo but if the dynamo can provide the 500mA also
 +
at higher voltages, you can gain more charge current than in 500mA mode if you have a switching regulator.
 +
For example if the dynamo would provide 10V 500mA and you would have a 100% efficient regulator,
 +
you would have 5V 1A.
  
If you decide to try solar, it's recommended to get a flexible panel and attach it to your backback or something like that. One nice advantage here is it might also charge even when you're not moving. It's unlikely anything below 7 watts will keep things running. (5v * 1A = 5W).

[edit] Power Supply

If you want to keep the GPS running and have the screen always on or staying on with a long timeout, you'll need a way to supplement power.

[edit] Charging via hub

Connecting a hub (Nabendynamo) like the SON to a self-made or prebuilt charger can supply your device while biking.

The FreeRunner has three different charging modes: 100mA, 500mA and 1A. 100mA seems to be too low, as it is said, that the FreeRunner draws 100mA current even when it is switched off. A hub dynamo provides 500mA. If you want to use your lights while charging you need to connect the lights in series to the charger. At least the SON will increase the voltage and still delivers the same current. But you need a bypass circuit in case of less current draw of the charger when the battery is full.

Using an USB connection with that ID resistor for 1A mode provides the advantages that the charging mode is automatically correct. This might be important if you stop frequently and so cause some kind of power "disconnect" and you do not want to select the charge mode all the time. 1A mode does not harm the hub dynamo but if the dynamo can provide the 500mA also at higher voltages, you can gain more charge current than in 500mA mode if you have a switching regulator. For example if the dynamo would provide 10V 500mA and you would have a 100% efficient regulator, you would have 5V 1A.
