Its usual retail price is US$26.99 (S$38) but because of an ongoing promotion, you can use the promo code, GEYC7LFE, and it will give you a discount of US$6.50.
Similar to most Anker products sold on Amazon, this wall charger does not ship to Singapore directly, and hence you have to ship it through a freight forwarder.
In Singapore, the official Anker Online Store is selling it for S$48.90 with free shipping within Singapore.
This charger allows you to charge a maximum of six USB devices simultaneously. It is capable of a maximum output of 2.4A per port or 12A (60W) overall.
Note that this charger does not support Qualcomm Quick Charge (QC), if you are looking for QC, then you need to get the Anker PowerPort 6+ on Amazon for US$35.99 (S$50). Or you can can get it from Anker Singapore Online Store for S$53.90.
Previously, I was using the Anker 40W 5V/8A 5-Port Wall Charger which I bought from Amazon three years ago.
