You can easily use the JNC660 charging extension cable. I decided that my JNC660 should be able to handle all options, so I bought a fabric case and this charging cable. The cable is well made and long enough to find a comfortable place to charge the jnc660. The charging cable is small enough to fit in a cloth bag for storage, making it less likely to get lost. Not exactly what you need to unload jnc660, but a good option.
