Spansive Launches Source, the World’s First Multi-Phone Wireless Charger that Shapes Magnetic Fields to Allow Alignment-Free Power Through Cases and Accessories

Proprietary software-defined induction technology wirelessly charges up to four devices simultaneously with Drop-N-Charge ease and requires no special alignment to charge properly


Spansive, the company building the next generation of wireless charging technology, today launches Spansive Source, the world’s first multi-phone wireless charger designed for families and shared spaces. Enabled by Spansive’s patented software-defined induction technology, Source wirelessly charges up to four Qi-enabled devices simultaneously with Drop-N-Charge ease that doesn’t require exact alignment and works with nearly all phone cases and popular accessories.

Source uses software-defined induction to shape magnetic fields and create the first wireless charging solution that allows every member of the family, regardless of their phone case, to easily charge their devices simultaneously without an unsightly mess of tangled wires. There are thousands of phone cases, all of them unique in their own way -- some thin, some thick, some with accessories like PopSockets. To date, the majority of wireless charging pads have only worked with a limited range of phone cases and required exact alignment to charge. Source is different. 

Spansive Source is available online and shipping today for $189 at

“We designed the Source as a beautiful and simple way to declutter charging so families can get charged and get on with their busy lives,” said John MacDonald, co-founder and CEO of Spansive. “‘Charging’ doesn’t mean a tangled mess of cables or finicky alignment on plastic pucks anymore. We’re thrilled to finally deliver the charging experience a beautiful home or office deserves.”

Spansive Source helps homes and offices simplify their shared charging space with these features:

  • Simply Drop-N-Charge: Just drop your phone anywhere on the Source and it starts charging. Spansive’s software-defined induction technology creates a PowerField -- a three-dimensional wireless charging field that can sense where devices are located on the Source and shape the field towards them -- it requires no special alignment.
  • Any Case Charging: Works with nearly all phone cases and popular accessories, like PopSockets™ and Otterbox™ cases.
  • No Phone Left Behind: The whole family can wirelessly charge up to four Qi-enabled iPhones or Samsung Galaxy devices and two devices via USB - no one is left with a dead phone and no one needs to fight over the charging cable. 
  • Beautiful, Clutter-Free Design: Eliminates ugly cable clutter, an issue that busy families know all too well. Source is meant to be placed in the busiest places of the home, for all to see, admire, and use.
  • WiFi Updates: Source connects to your WiFi network to allow automatic software updates, ensuring you constantly benefit from software improvements improving charging speed, charging range, and adding compatibility with future devices.

Placed in shared locations such as kitchens, living rooms, offices, or bedrooms, Source serves as a central hub for a family’s unique array of devices and helps provide a reminder to put devices down for meals and bedtime.
