I doubt it. But there are usually 3rd party brands that make some kind of charging case.
It would be cheaper and more effective to get the spare battery kit IMO. Then you don't have to bulk up the phone anymore and swap whenever you need to.
To be honest I keep forgetting about being to swap batteries.. in all reality I'm never to far from a charger of some sort but in case of a zombie break out a fully charged extra battery is a plus!
