Wall chargers, from compact single-port units to high-wattage multi-port GaN bricks.
I bought the Energea Travelite 34W 4-Port Wall Charger at Challenger Bugis for S$59, or S$53.10 with the member's discount. It delivers a combined 6.8A across four ports, two at 1A and two at 2.4A, with a US-to-UK adapter.
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.
I backed the Flip British Plug on Kickstarter in November 2015, a project that raised £28,115 from 1,140 backers. I chose the £14 reward, paying about £19 with shipping for one Flip Quad, a thin, foldable British plug.
I bought the Google Universal 22.5W Dual Port USB Type-C Charger with its USB-C to USB-A cable for US$39.99, forwarded via HopShopGo. It's the only trustworthy, reasonably priced charger I found with two USB-C ports.
Oneadaptr began with a Kickstarter project for Twist, raising US$36,226 against a US$30,000 goal from 552 backers. Twist is an ultra-portable universal adapter for the MacBook charger, offering far more than Apple's World Travel Adapter Kit.
The Belkin Tablet Charger is the other gift I received from Belkin Singapore for Christmas, alongside the Belkin Lightning to USB ChargeSync Cable. I suspect it's since been renamed the Belkin Universal Home Charger, as I couldn't find it listed.
The Innergie USB Charger Duo Charging Kit (Home) sells at Challenger for S$50, or S$45 after a 10% member's discount, and I got mine from VivoCity's Challenger. There are two versions, home and car, with the car kit slightly lower.
