This $20 accessory is a must for anyone with a MacBook

• Ten One Design's Blockhead side-facing plug is the best $20 accessory you can buy for your MacBook.
• The side-facing plug saves you a ton of space, and it works with every MacBook and iPad charger model.

When you think about Mac accessories, you’re probably not thinking about chargers.

But this particular charger — from a Montclair, New Jersey accessory maker called Ten One Design— is as simple as it is clever (which is “very”), and absolutely worth your money.

Take a look.

MacBook computers come with big blocky chargers that stick directly out of the socket when you plug them in.

Apple also gives you a cord to extend the length of the charger, but it still sticks out a lot.

With this adapter from Ten One, though, your MacBook charger will sit flush with the wall or port it’s charging from.
