Oneadaptr Twist and Flip world travel adapters and charging stations.
The Evri 80W USB-C Charging Station retails for US$74.99 plus shipping to Singapore. Evri is the USB-C product range from OneAdaptr, the company behind the Kickstarter-funded Flip plugs. There are currently three products in the Evri lineup.
The Flip World Add-On retails for US$9.99 and includes US/AU and EU plug add-ons, compatible with the Flip Duo, Quad, and Power. I bought it to use with my Flip Quad, the prongs rotating to fit various regions.
After the Kickstarter success of the Flip British Plug, OneAdaptr announced the Flip World range in November 2017, spanning four products from the Duo to the Power World. Pre-orders got 30% off with the code WorldIn18.
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.
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.
