You know what the Innocell needs
Introducing the Innokin iHub
They already make USB hub strips with the USB ports (female end)
But instead of having USB ports they would have the USB Plugs (male end) that stick out of the strip,
and you can hang your Innocell batteries on it
Picture that USB strip having plugs sticking out instead of them ports,
Now Picture this battery turned upside down and plugged into that strip.
Like a coat rack for InnoCell batteries
BUT THERE'S MORE,
I believe the Innocell is 1-7/8" wide so the hub would also charge Devices like the MVP 3.0 (1-3/4" wide)
and the Cool Fire IV (1-5/8" wide)
I give you The Innokin iHub
