Bought the Energea Amp Charger 17W 5V/3.4A 2-Port Wall Charger  for S$26.90 (S$24.21 after 10% member’s discount) at Bugis Junction’s Challenger.
I am surprise that Challenger’s online store, Hachi.tech , is selling it more expensive at S$35.10, excluding a 5% rebate.
I always have the impression that Hachi.tech is cheaper than Challenger’s own retail store. I guess I will have to compare the price first before considering my purchase at Hachi.tech.
This is a 2-port charger that is capable of a combined output of 3.4A or a max of 2.1A per port. You can charge a tablet and a smartphone together but not 2 tablets simultaneously.
The reason I bought this charger is because I needed a compact UK plug wall charger without additional power adapter. It will be used to power my IoT devices like my motion sensors.
My budget is below S$30 and it seems this is the most decent and nicest looking charger I can find at Challenger.
