Sigh. I did not realize that 18650 was a battery style like AA, AAA, C or D. I unscrewed the cover, dropped in a AA battery and it rattled around. I'm thinking WTHeck?
No big deal but the extra wait is irritating.
I now have the 18650 batteries on order from a Canadian vendor so I should have them in a week or so.
What that eBay listing also did not make clear, at least to me, is that it also charges the internal 18650 batteries from a standard USB port. I had assumed you'd have to charge the AA batteries from an external battery charger. And you can charge those batteries at the 2 amp rate using your Kobo charger.
I wonder what the capacity of the Vox internal battery is? The four batteries I purchased were 3.7 V at 2400 mah. The tech specs just state 7 hours battery life.
