Ten One Design’s Blockhead is another solution to the MacBook’s sometimes unwieldy plug, which causes the power supply to jut out from the wall. Blockhead replaces the power adapter’s plug with its own removable plug, enabling the adapter to charge while flush to the wall. Blockhead works with MacBook power adapters, whether 29W, 60W, or 85W, and the little blue plug also works with the 12W iPad charger. One Blockhead goes for $20, and a two-pack costs $35.
