Image 1/2: In order to get into the inner working, we will need to use our trusty plastic opening tool to pry off the lid to the charger. Image 2/2: The lid is easy enough to remove and the green rim slides right out as well.
  • Just like most car chargers, the case does not have an obvious entry point.

Image 1/1: From here we can see:
  • Now we get out first glimpse at the circuitry that allows our Quick Charge 2.0 compatible devices to charge...well quick.

  • From here we can see:

    • USB adapter

    • LED that shows charge status

    • A big capacitor

    • Some USB chip (assuming its proximity to the USB adapter)

Image 1/3: Squeezing the shell across the seem causes the connecting tabs to separate enough for us to pry them apart. Image 2/3: Inside the shell are three metal leads that fell out when the shell pieces separated. Image 3/3: Inside the shell are three metal leads that fell out when the shell pieces separated.
  • To separate the last part of the outer shell, we need to apply some pressure from with the vice grip pliers.

  • Finally we can see what makes this charger tick and It seems that there are two important chips at work here:

    • Active-Semi ACT4533C DC/DC Converter

    • Power Integrations CHY100D-TL Battery Management Charger Interface

  • These two chips in tandem make this CLA possible with so few parts, including:

    • a couple resistors and capacitors

    • an inductor

    • a fuse

    • and two diodes

Image 1/1: It was very easy to remove the lid of the casing
  • PureGear Extreme USB Car Charger Repairability Score: 7 out of 10 (10 is easiest to repair)

    • It was very easy to remove the lid of the casing

    • There are few parts to disassemble

    • There was not an obvious way to separate the two halves of the outer casing

  • The charger reassembled very easily without any need for repair

  • It's amazing how PureGear was able to make a Quick Charge 2.0 compatible charger with so few parts.
