There's a project on KickStarter called BeeKeeper you should check out if you have a new MacBook. It's a USB-C to Standard USB cable coupled with a converter that allows you to plug any standard USB cable into your MacBook. If you use the converter in conjunction with the cable, you can use them with Apple's MacBook charger. But if you use just the converter, you can plug, say, your existing Lightning iPhone cable—or any other standard USB cable—into your MacBook. Funding levels start at $19 for the converter by itself, or $36 for the converter and the cable. The company has raised $9,000 of its $33,000 goal, with five days left in the campaign.
