The Anker Powerline+ II is Anker's second MFi-certified USB-C to Lightning cable, after the Powerline II. The only real difference is the exterior: the Powerline+ II uses nylon braid versus the Powerline II's TPE, both with reinforced strength.
I bought the Anker Powerline II USB-C to Lightning Cable from Amazon for US$17.99, available in black and white. This Powerline II uses a TPE casing; I'm hoping Anker brings it to the nylon-braided Powerline+ II series.
To charge a USB-C MacBook Pro, your cable must support USB Power Delivery. The Anker PowerLine USB-C to USB-C Cable retails for US$15.99 in a 0.9m length, a cheaper alternative to Apple's 2m USB-C Charge Cable at S$48.
I bought the Anker PowerLine+ Lightning Cable (0.9m) from Amazon for US$13.99. Since it doesn't ship to Singapore directly, I forwarded it via HopShopGo. It comes in four lengths, from 0.3m at US$12.99 up to 3m at US$16.99.
