Energea Amp Charger 17W 5V/3.4A 2-Port Wall Charger
I bought the Energea Amp Charger 17W 2-Port Wall Charger at Challenger Bugis Junction for S$26.90, or S$24.21 with the member's discount. Surprisingly, Challenger's own online store Hachi.tech listed it pricier at S$35.10, upending my assumption it was cheaper.
