Yesterday, I went to IKEA in Logan for shopping. I found their product ranges are expanded in the tech side too. There are some wireless chargers. Also, I found this fancy battery charger too. It looks pretty and it can charge ten batteries each times. In addition, it got a digital display which can indicate the charged level of each battery, that looks great! But it costs AUD$40, which is a bit too much for me. I did not buy this.
