I backed the Flip British Plug on Kickstarter on 22nd November 2015. The project was funded on 18th December 2015 after raising a total of £28,115 out of their initial goal of £15,000 from 1,140 backers.
I chose the £14 reward level and shipping to Singapore cost another £5. So in total, I paid £19 (S$38).
This is probably the only trustable USB Type-C Charger that I can find which has more than one USB Type-C port and is reasonably priced. Besides the charger, it also comes with a 1.8m USB Type-C to Type-C cable (USB 2.0 speed) which itself already cost US$19.99 (S$29).
About Oneadaptr Oneadaptr started out from a Kickstarter project based on their product called Twist. They raised a total of US$36,226 out of their initial goal of US$30,000 from 552 backers.
Twist is a ultra-portable universal adapter designed to work with the MacBook adapter. It offers much more functions than the Apple World Travel Adapter Kit and makes charging your mobile devices much easier. Some of its functions include, four USB ports for charging, universal outlet and the intuitive twist-to-change adapter type design.
I think the Belkin Tablet Charger has been renamed to Belkin Universal Home Charger since I could not find the Tablet Charger being listed on their website and the Universal Home Charger looks exactly the same (besides the color) as the Tablet Charger.
