DJI Doesn't sell just the cable.  The only option I can suggest is to check eBay for the missing cable, but a complete new charger, or get a 3rd party charger. Like this

It is the same cable that comes with the default charger that comes with the Spark.  They are exactly the same part #'s if you have that one.
