Hmm, 6h is obviously not going to hack it, with 13h between sunset and sunrise. Just hooked it up to my Nokia DC16, it seems happy to run off an external source.
EDIT: It went at least 11h on high-constant starting from internal battery fully discharged and the DC16 not fully charged. With the smaller but more energetic DC19 and both fully charged, 18h on high-constant should be possible.
