A new company called Visor Solutions is selling a Prism Battery supply/charger that looks exactly like the Emergency Charger from Tech Center Labs. The total price for the BS/C is $33 for the adapter and battery pack.
I know competition is a Good Thing™, but companies should differentiate themselves somehow from would-be competitors. Perhaps a cobalt-blue battery and adapter casing that isn't so squarish? That would match the Visor Prism's color and be different from other charging solutions.
