DIY IPhone Hyper Charger | Charge Your Phone 2x Faster!

Introduction: DIY IPhone Hyper Charger | Charge Your Phone 2x Faster!

About: I'm 16 years old and live in Bradenton, Florida. I like Ham Radio, very fast SBC's, and giant capacitors! Also a bunch of other stuff that I can't think of right now :)

Hey everyone, and welcome back to another Ben Builds instructable!

In this instructable, I will be showing you how to build a phone charger that is capable of outputting 5v @ 2A from a 12v car power port. This charger uses some fancy voltage tricks to tell the iPhone that it's an iPad charger when it's not. This makes the phone charge at 2 amps instead of the traditional 1 amp giving you double the charging speed! This does not hurt the phone at all as it is supported by the Apple charge management chip located inside the phone.

Ok then, lets get started!

Step 1: Watch the Video!

On the video I go over all of the steps in this instructable in detail and with moving pictures!

It'll probably help if you watch the above video before proceeding. Below is a materials list along with the schematic for building it.

Step 2: Materials?

For this project you will need:

An Altoids Tin

Electrical Tape

2 50k Resistors

1 75k Resistor

1 43k Resistor

USB Port

DC-DC Buck Converter

Volt + Amp Meter with LED Display

Superglue

Step 3: Prepare the Tin

Take the altoids tin and put a layer of electrical tape on the bottom to prevent short circuits and also drill and hole in the back right wall and cut a slot for the USB port on the left side.

The video demonstrates these procedures so you get them perfect!

Step 4: Build the Electronics

Follow the above schematics and the section in the video to build the circuit.

You'll also need to calibrate the DC-DC converter which can be accomplished by using your digital multimeter to measure the output of the DC-DC converter and using a small common screwdriver to turn the little brass knob until you get to 5.2v. This process was filmed and is in the video too.

Step 5: Meet Your Meter

Next, we need to install the Volt + Ammeter. This unit can be found inexpensively on eBay by searching for "LED Volt Amp Meter" and needs a hole cut in the case for it.

The meter was measured and an appropriate hole was cut using a box cutter. The meter was pushed in place and further secured with superglue.

Step 6: Glue and Wire It Up

Wire everything according to the video and schematics and use hot glue to glue the pieces in and you're done!

Thanks for reading and I'll see you in the next Instructable!

If you have any questions at all, please leave a comment and I will get back to you with an answer!

    Cool stuff, but why setting the output to a bit more than 5.0 V, which is the excepted output of USB (I think) ?

    becous the voltage drops a little on the meter and on the cable

    5.2 is the max save voltage for usb

    usb power supply must be between 4.8 and 5.2 v to work

    so if you set it at 5.2 you can lose 0.4 v

    0.4v /2A = 0.2 ohm

    but most phones wil accept lower voltages but 4.5V at the device wil reduce charging curent

    Please check your schematic diagram. I think you have the USB plug wired wrong. Ground appears to be positive when it should be negative and VBus is negative when it should be positive. Check out this link.

    Wired this way will destroy your phone.
