Edit Step 2 Materials  ¶ 

  • Before beginning, lay out the contents of the Magic Box kit. They should include (clockwise from the left):

    • Car Adapter

    • Large Magic Box

    • Small Magic Box

    • Wire Strippers

  • Also locate the MagSafe charger you wish to modify.

Edit Step 3 Modifying Power Adapter  ¶ 

  • Make sure that the power adapter is disconnected from the wall outlet and MacBook.

  • Use a pen to make a mark on the MagSafe cable about 4" (10 cm) from the MagSafe connector.

  • Use a pair of wire cutters or scissors to cut the cable at the mark you made about 4 inches from the MagSafe connector. Set aside the MagSafe connector wire for later.

  • Although the wires inside the cable are copper, they may damage some scissors. We recommend using wire cutters if possible.

Edit Step 4  ¶ 

  • Use a pen to make a mark about .75" (2 cm) from the cut end on the side of the cable attached to the power adapter.

Image #1

Edit Step 5  ¶ 

  • Before using the included wire strippers, we recommend cleaning the upper and lower flat areas where the tool grips the cable with de-greaser. The manufacturing process leaves a small amount of grease on these areas that may stain the white cable you are about to strip.

Image #1

Edit Step 6  ¶ 

  • There are four stripping holes of varying sizes on the wire stripper.

  • Carefully position the cable in the largest (innermost) hole on the wire stripper and line up the edge of the jaws with the mark you just made as seen in the first picture.

  • Squeeze the wire stripper to remove the outer cord tubing, revealing wire strands beneath.

  • If necessary, slide the outer sheath off the end of the cable.

Edit Step 7  ¶ 

  • Gently move the fine wire strands aside to reveal an inner wire.

  • Twist the loose outer wire strands together into a single twisted strand.

  • If you are handy with a soldering iron, tinning the ground lead after you twist it together will help keep it in one piece.

Image #1

Edit Step 8  ¶ 

  • Use a pen to make a mark about 3/8" (1 cm) away from the end of the inner wire.

Image #1

Edit Step 9  ¶ 

  • Using the wire stripper again, align the edge of its jaws with the second smallest hole on the pen mark made in the previous step.

  • Squeeze the wire stripper to strip off the insulation on the inner wire.

Image #1

Edit Step 10  ¶ 

  • As before, twist the center wire strands tightly into a single twisted strand.

Image #1

Edit Step 11  ¶ 

  • Line up the outer and inner twisted strands side by side and trim the ends of both wires to make them equal in length.

  • Do not trim too much!

Image #1

Edit Step 12  ¶ 

  • Locate the Large Magic Box.

  • Remove the cover of the Large Magic Box and set it aside.

Image #1

Edit Step 13  ¶ 

  • Before attempting to insert the wires, note their correct orientation. The center wire should be inserted into the positive (+) terminal on the left and the outer wire should be inserted into the negative (-) terminal on the right.

  • Use your thumb to push back the orange spring clamps on both terminals and insert both wires into their respective terminals. Insert the wires as far in as possible.

  • Make sure that exposed strands of the positive and negative wires do not touch each other when installed in their final positions in the terminals!

Edit Step 14  ¶ 

  • Replace the Large Magic Box cover.

Edit Step 15  ¶ 

  • Congratulations! You just modified the MacBook Power Adapter to be capable of recharging the HyperJuice battery directly.

  • To charge a first generation HyperJuice battery, plug the male connector from the Large Magic Box into the CHARGE port on the HyperJuice battery.

  • To charge a HyperJuice 1.5 or HyperJuice 2 battery, use the short male to male cable that came in the kit to connect the Large Magic Box to the DC IN port on the HyperJuice Battery.

    • The female connector has the higher voltage required to change the newer batteries.

  • The LED light on the Large Magic Box will be RED during charging of the HyperJuice battery and will turn GREEN when it is done charging.

Edit Step 16 Modifying MagSafe Cable  ¶ 

  • Now let's repeat the process with the MagSafe end of the cable and the Small Magic Box.

  • On the the cable with the MagSafe connector, as before, make a mark .75" (2 cm) from the cut end.

Image #1

Edit Step 17  ¶ 

  • Again, use the largest (innermost) stripping hole to remove the outer cord tubing at the mark you just made.

Image #1

Edit Step 18  ¶ 

  • Unravel the outer loose wire strands and twist them into a single strand.

  • If you are handy with a soldering iron, tinning the ground lead after you twist it together will help keep it in one piece.

Image #1

Edit Step 19  ¶ 

  • Make a mark on the inner wire 3/8" (1 cm) away from the cut end.

Image #1

Edit Step 20  ¶ 

  • Align the second smallest hole with the pen mark made in the previous step.

  • Strip off the inner tubing at the mark you just made to reveal the center wire strands.

Image #1

Edit Step 21  ¶ 

  • Twist the center wire strands tightly into a single twisted strand.

  • Line up the outer and inner twisted strands side by side and trim the ends of both wires to make them equal in length.

  • Do not trim too much!

Image #1

Edit Step 22  ¶ 

  • Locate the Small Magic Box.

  • Remove the cover of the Small Magic Box and set it aside.

Image #1

Edit Step 23  ¶ 

  • As in step 13, use your thumb to push back the orange spring clamps on both terminals and insert the center wire into the positive (+) terminal on the left and the outer wire into the negative (-) terminal on the right.

  • Make sure that exposed strands of the positive and negative wires do not touch each other when installed in their final positions in the terminals!

Image #1

Edit Step 24  ¶ 

  • Replace the Small Magic Box cover.

Image #1

Edit Step 25 Finished  ¶ 

  • With that, you have successfully modified the Apple MacBook Power Adapter with the Magic Boxes.

Image #1

Edit Step 26 Operation  ¶ 

  • Use the modified MagSafe Cable to power and recharge your MacBook with HyperJuice external battery. The LED light on the Small Magic Box will light green during use.

  • Connect the modified MagSafe Cable to the MacBook Car Charger to power and recharge your MacBook in the car.

  • Connect the Small Magic Box to the socket in the Large Magic Box to regain the original functionality of the Apple MacBook Power Adapter, i.e. to power the MacBook. We hope you like our Magic Box solution.

Any chance you could do a teardown of what's inside the magic boxes? It seems to me that there must be some actual magic in the large magic box (and the small is essentially just wiring straight through).

I tried soldering on some $1.50 DC power connectors instead of paying $50 for the magic box. The cable from the battery to the laptop works perfectly, but the HyperJuice battery doesn't charge from the Macbook power adaptor - there must be something more required. Any insights into what the large magic box does would be appreciated :)
