The USB Chargers (1S version and 1S/2S version) now come with a total of four ports, instead of the older version that came with six ports. This was a running production change made in the effort to promote compatibility and additional charging safety. While there was no safety issue with the older six port chargers, we could not guarantee that customers were using a transformer/adapter rated for enough current to support charging so many LiPo batteries at a time. In order to be more compatible with commonly used USB transformers/adapters in the 5V/~2A range, the transition was made to our newest four port chargers.

(* Some product photos/descriptions still show the older six port USB chargers. Those are outdated and are still being updated. Please disregard.)
