ChargeSpot is a wireless charger that is friends with both PMA and Qi standards
ChargeSpot is a wireless charger devised with venues and offices in mind, supporting both of the most widely adopted, but warring, Qi and PMA standards. It is designed to be installed just beneath the surface of a table, with a stylish sticker to mark its location on top. The charger also offers an accessory for phones that don't have built-in wireless charging – it kind of looks like a table coaster and has a micro-USB or Apple Lightning connector at one end.
Along with the obvious simplification of wireless charging in a standard-separated world, ChargeSpot's creators claim that the device is very efficient – outputting 5W of power, it should charge your phone with almost the same speed as your wired charger. They've also included an automatic on-off tech, which does not allow the charger to accumulate any phantom usage, when there is no device to charge.
In order to help venue managers follow usage, ChargeSpot has a cloud monitoring system, which displays data on how much each installed device has been used.
It would be nice to see this multi-standard support adopted by more charger makers. In a perfect world, your choice of coffee shop should not be predetermined by its support for your phone's wireless charging, but by how juicy its doughnuts are.
