    • 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

    • 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.

    • 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)

    • 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.

    • 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

  6. Car Charger Teardown: étape 6, image 1 de 1
    • 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.

Any info on the USB chip?

I need help fixing a car charger. I think the fuse is blown. It's an Ainope AV804. I don't see how to take the face off. I'd rather send it to you for repair.

Please email me at: WFBanach@aol.com

Great insight on how to open one of these. I had a different vendor adapter and it opened almost exactly like the one you showed.

Thanks!
