Questo smontaggio non è una guida di riparazione. Per riparare il tuo Apple 5W USB Power Adapter (Folding Pins - UK plug), usa il nostro manuale di assistenza.

    • Released with the Apple Watch in the UK / HK, the new folding plug has pins that fold completely flush for travel.

    • Matches the older style plug with a 5W / 1A specification.

    • AC 100 - 240V input.

    • This product uses and can store high voltage electricity - it is dangerous and could potentially kill you.

    • Becoming more common on mains chargers, most of the design is fastened together during the moulding process. There is only a single screw (Torx T9 M2.5 x 2.75mm) in the entire product.

    • You could possibly pry this open, but you would likely make a big mess. Instead this has been cut in two using a fine bladed coping saw.

    • This was cut 1mm behind the USB port entrance.

    • Inside we can see the design has been split into two halves.

    • All of the electronics are on a single PCB on the left.

    • All of the mechanism and high voltage contacts are on the right hidden under plastic hood.

    • A break down of the top side of the PCB:

    • Rubycon 4.7µF 400V electrolytic capacitor 400AX4.7M8X9

    • Fairchild bridge rectifier MB10S

    • Everlight optoisolator EL3H7-G

    • Transformer markings 157-00003 / HIG J 1503

    • There's copper shielding to meet EMC requirements on the rear of the housing.

    • On the reverse side:

    • Fairchild PWM Controller FAN301

    • Fairchild N-Channel MOSFET STD7NM64N

    • Recessed inductor markings T00405 SP451

    • KEMET Tantalum Polymer Capacitor T520M157M006ATE035

    • Diode SBR8U60P5

    • There's a blob of resin over R9 - a mistake?

    • FAN301 currently has an injunction against it due to patent infringement. Perhaps this doesn't affect European sales?

    • Most of the mechanism is covered with a hood, fixed at points using thermoplastic staking during production.

    • The only way to remove the cover is to cut the tops off these.

    • Finally we can see how the mechanism works!

    • The yellow tape is Polyimide high temperature film.

    • The cover is needed for the mechanism to work properly - the central black plastic piece will lift otherwise.

    • With the side of the bottom section filed away, you can see the stackup of the PCB, mechanism and contacts exposed.

    • The Apple folding charger repairability Score: 1 out of 10 (10 is easiest to repair)

    • Almost everything is moulded together during manufacture, making it impossible to take apart without damage.

    • Trying to reassemble this and use it would not be safe!
