在此拆机指南中使用的工具

简介

Continuing in my fascination with Quick Charge 2.0 based chargers, this is the second teardown of the fast charge series.

这个拆解是不是维修指南。 要维修你的的Car Charger,请使用我们的维修手册

  1. PureGear's Extreme USB Car Charger is an elegant cigarette lighter car charger with a smooth, matte outer casing. This charger is able to charge devices with Qualcomm Quick Charge 2.0 compatible processors up to 4 times faster. The adapter is rated at 12W with 5V/2.4A for Quick Charge compatible devices and 5V/1A for all others.

    • The charger includes:

    • USB adapter

    • LED to indicated status of charge

  2. Just like most car chargers, the case does not have an obvious entry point. 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.

    • The lid is easy enough to remove and the green rim slides right out as well.

  4. Now we get out first glimpse at the circuitry that allows our Quick Charge 2.0 compatible devices to charge...well quick.
    • 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)

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

  6. 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
    • 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

  7. PureGear Extreme USB Car Charger Repairability Score: 7 out of 10 (10 is easiest to repair)
    • 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.
