Samsung, for whatever reason, has not released a back plate for the Galaxy S4 Active that allows it to take advantage of Qi wireless charging. The folks at Monster Watts seemed to have a solution with their WIQIQi battery attachment, and even managed to pull off a successful Indiegogo campaign. However, legal issues have forced the cancellation of the product.
The company makes WIQIQi attachments for several other devices, but according to the campaign site, legal issues with the water-resistance claims of the GS4 Active gave them pause. After consulting with council, Monster Watts has decided to stop production of the GS4 Active wireless receiver and destroy all the stock.
It's not all bad news, though. The company has decided to refund all backers the full value of their pledge. Alternatively, anyone who wants the regular GS4 WIQIQi attachment instead can have one with a $15 refund. Monster Watts is careful to point out this version does not assure the water-resistant back continues to function as intended. A sad end, but not as sad as it might have been.
