I had to use my pocket knife to slip it in between the spring loaded metal ground part and the plastic case. Make sure you identify which side will lift off. The top part is attached to one of the halves and you don't want to pry against that side. Just put a bit of pressure on each side until you can crack it apart. When putting it back together, I had to use some super glue on each side of the case after I had pressed it together. Just a couple of drops on each side and it looks none the worse for wear. Except it now charges at a a full amp (probably 800 milliamps)

Just to verify, this is the Belkin charger in question:

[EVO 4G Accessories] ChrisDos:
Download spare parts from the market. Under battery information it will tell you which mode it's charging in. Either USB or AC.
[EVO 4G Accessories] Andy S:
Thanks. I knew I was missing something. :)
[EVO 4G Accessories] SteelH:
Battery droid will also tell you USB vs. A/C charging.
[EVO 4G Accessories] JKGoodrich:
Go into Settings, About Phone, Battery... It will say under Battery Status (just in case you don't want to download a new app)
[EVO 4G Accessories] Andy S:
Thanks all.

Now if I could find my soldering iron, I'll attempt this on my 1A wall charger from a time circa Rio Carbon :D
[EVO 4G Accessories] ntron1:
Thanks, 5 minutes and worked like a champ.
[EVO 4G Accessories] Andy S:
Ten minutes of looking for a lost soldering iron, and the Rio Carbon's charger now shows AC. Cool.

Thanks. I'm planning a hardwired mod to make a physical mount (out of a $5 ebay belt clip that I'm going to saw the clip off of...) in the empty Nav hole on my car. Have been trying to find a cheap donar USB plug charger to wire straight into the fuse box, and this will make that search easier.

Back to this one about grounding pin 4. I know that in another thread someone mentioned hacking a cable on the mini USB end to bridge pins 4 and 5 (the "X" on the diagrams on the second page linked in the first post) to automatically put the car in "car dock" mode. Any ideas how we could accomplish this at the regular USB plug end, since there are only 4 contacts on that side?
[EVO 4G Accessories] ChrisDos:
Glad to see that the modified charger is showing AC. Afraid I don't know about the car dock mode. Haven't researched that yet.
[EVO 4G Accessories] kennyc1:
Thanks again OP. Just modified one and it worked perfectly.
[EVO 4G Accessories] scl23enn4m3:
I don't think you understood my question...Grounding 4 (same as bridging it to 5) should kick the phone into dock mod. So if I can pull an amp and get it into dock mod in my car, it'd be perfect.

I believe pin 4 doesn't get used so it's the one missing on the regular USB side...Based on that it would make sense for a wire from pin 4 to not extend all the way. You might just be stuck with with opening it towards the micro usb end.
[EVO 4G Accessories] bryank930:
My htc wall charger shows AC charging. So does my motorola car charger. Do I need to modify anything??
[EVO 4G Accessories] ChrisDos:
Nope. Motorola made their charger properly and already grounded pins 2 and 3. You are already good to go.
[EVO 4G Accessories] Jafar91:
Thanks for the post. I did confirm what you said. I charged it on one side of a dual charger rated at 1amp each side. The sided I soldiered I was able to charge about 1% per min over a 5 min period. The side that did not have 2 and 3 shorted I got about .5% to .6% over a min over a 5 min period I know my test was not scientific since we know batteries charge at different levels over different percent charged. But the difference was significant enough that I belive it is pulling more power.

Great post and thanks for the info. Kinda funny they can sell a 1amp charger when they know it wont pull more than .5 unless those pins are shorted. Kinda like the iphone charger scam.
[EVO 4G Accessories] ChrisDos:
I wonder if this post should be moved to the general section then. It's important enough that more people should know about it. Can a moderator move it to the General section or should I just make another post in the General section?
[EVO 4G Accessories] skydeaner:
cool, manufacturers of these things are retarded. why not ground 2 and 3 if your device can't communicate with anything and is just made for charging other devices lol.

Works great on my efx? schosche? brand white dual usb car plug i got from either walmart or meijer, can't remember which.
[EVO 4G Accessories] VW91N3:
2-amp automotive chargers, with htc on them, go for a couple of bucks on eBay. For those who are a bit iffy at doing board-level solder jobs, or whose time is worth anything.

The batteries used in the Evo have circuitry that prevents "speed charging" them. So long as you can supply 1 amp, that's the most the battery will allow in. The days of the (sucking) NiCad batteries is gone. Thankfully.
[EVO 4G Accessories] kellybrf:
so i popped it apart and im assuming its the four solder marks behind the r5 and r7 and that i just connect the middle two ones, but just wanted to confirm i was doing it right. thanks guys!
[EVO 4G Accessories] scirio:
How in the **** did you ever open the Belkin charger. That thing has no seams. Please explain.

I have the Belkin Micro cig port charger. That what you have??

EDIT: holy crap, my question's already been answered right above my post :)
[EVO 4G Accessories] Andy S:
Yep. The middle two pins sticking up behind the resistors.
[EVO 4G Accessories] ViViDboarder:
Did you try shorting 4 too?

Also, do you know what pin throws the phone into Desk dock mode? I read before about how 4 does Car mode.
[EVO 4G Accessories] kellybrf:
worked like a charm, thanks! fwiw i didnt need to use super glue to put it back together either, it just kinda went back in (didnt even snap)
[EVO 4G Accessories] potna:
Does anyone know why these charges sometimes dont have pins 2 and 3 shorter?

Just seems like there would be a reason.

Also, when you have a full 1amp charge should it charge faster then the phone drains while using say.... Google navigation?
[EVO 4G Accessories] Ohm2k:
It's a mix of cost and safety. Our nice little EVO devices can pull some serious juice, and if someone plugs one into a charger that is rated for 200ma but has those pins shorted then all sorts of fun can happen.

You really shouldn't just short those 2 pins out, there should be a resistor in there. Something low resistance as the wiki article points to (200Ohm max) But it don't look like the EVO cares. That little resistor cost money, and when you are looking at RAZOR THIN profits with Chinese manufactures you cut parts where ever you can.

To the person who wanted to know about connecting pins 2&3 to 4 to create a car doc? Looking at the USB spec datasheet It's not that simple. You need to insert a voltage divider across the data lines and tie it back into the 3.2v of the device. A little more trouble than it's worth unless you are doing it for the learning experience.

I've ripped apart and rebuilt tons of these 12v Car to X device chargers. Those things are plentiful, cheap and easily modified. Most these days are based on the 3843 PWM IC. A DC to DC converter that can also be used as a Charge Pump. (Think, change a few caps and resistors around and you can charge your phone about 1/2 way with 2 AAA Batts. Googly MintyBoost if you are looking for a kit or more info, I have nothing to do with adafruit, just a fan of her work and her open source hardware movement)

Dollar Tree has a 2 USB port charger that says 2 1A ports, but the CHIP is rated for 1.5A max so I wouldn't plug 2 evos in. One port has the data pins shorted and the other does not so they are never in danger of 1.5A being reached.
[EVO 4G Accessories] phatmanxxl:
Any reports of hot batteries while using one of these modded chargers? I had that problem with my last phone while using gps and I was getting worried about damage to the phone and/or battery.
[EVO 4G Accessories] tracerit:
all i have to do is solder the two pieces circled yellow?
[EVO 4G Accessories] tracerit:
what's the search term for finding the chargers? i can't find any.
[EVO 4G Accessories] mizzos4:
That would be correct. I've done that on two of my car chargers and so far no problems. Shows up as AC charging now.
[EVO 4G Accessories] tracerit:
thanks.

so quick question, why does belkin, scosche, and other companies advertise their car chargers as 1A rated when they only go at 500ma?
[EVO 4G Accessories] ViViDboarder:
Good info. I am someone who likes doing things for the experience. Could you help me out with a link to the spec sheet where you found that info?
[EVO 4G Accessories] scirio:
exactly whatI'm wondering!
[EVO 4G Accessories] pinoyxpryde:
its dependent on how the phone reads the charger. im sure most any other device would charge at more than 500.

I think this is an effect of Apple's decision to not let most ipods charge without a data signal, regardless of usb/AC usage

Does anyone know if the power jolt dual pops open easily?
[EVO 4G Accessories] tracerit:
just soldered my belkin micro charger. works perfectly as AC charging now. thanks!
[EVO 4G Accessories] Ohm2k:
Here is a link to the data sheet for the IC that most of these Car Chargers Use.

Why not just buy a 1A rated car charger or 1A rated charge cable that does not sync....they are only a few bucks a Frys
[EVO 4G Accessories] kennyc1:
how the hell do you open that up? is there a screw hidden somewhere?
[EVO 4G Accessories] ChrisDos:
Posting this from my Evo... I wrote an answer how to open it up earlier in the thread.
[EVO 4G Accessories] tracerit:
yup, i pretty much just followed what ChrisDos mentioned. it took a bit of force to pop the two pieces apart. In the end I just taped them instead of super gluing them.
[EVO 4G Accessories] kennyc1:
D'oh!

Got it! Thanks!

Kenny
[EVO 4G Accessories] mizzos4:
Well, that's what my car charger stated it was but without the shorted data pins, it only shows up as usb charging. Therefore, why buy more "1A rated" chargers when this is an easy cheap quick fix. Thanks again OP.
[EVO 4G Accessories] skydeaner:
Exactly. I have purchased 3 different types of 1a and 2a rated car/home chargers and none of them detected AC charging except for the HTC original. After shorting the 2&3 pins they all show ac charging. I didn't need this guide, i already knew about it, being a computer tech, but I am glad someone posted a how-to for everyone, as I am working on a huge kernel write-up and don't have time.

On a side note. The ebay 1a rated chargers I got, upon bridging the 2&3, make my screen lose touch sensitivity while charging. I am going to yank it back apart and compare it to my stock HTC A/C charger and see what the difference is. I'll post back on that some time tonight.
[EVO 4G Accessories] dslisfree:
The palm pre 1 amp car charger doesn't need any modification. My evo recognized it as an ac charger out of the boxo.
[EVO 4G Accessories] mntbkr:
I'm happy for you, here is a cookie. For those of us that have a 12v usb car charger and don't want to spend more $$ this is great info. Thanks to the OP for spending the time researching this and posting. we really could use more people like you around here.
[EVO 4G Accessories] wrapkgb:
I have a 2.1 amp powerjolt car charger.. Prior to reading this thread I ordered a charge only usb cable. Since it is not capable to transfer data will that do the trick without me having to take the charger apart and soldering it? Anyone try a charge only usb cable?
[EVO 4G Accessories] aduljr:
The USB wall and car chargers from monoprice need no modification, show up as AC on the phones and work at the rated 1 AMP.

Wall chargers are Item numbers are 6767,6784 for a little more than 2 bucks

Car chargers are item numbers 3523,6766 for a dollar something. Also have great pricess on USB cables with micro usb ends.
[EVO 4G Accessories] Andy S:
There's a whole thread on specific chargers that are set up to work correctly. We all know a lot do.

I have several already that I've had for a long time that don't show as AC. That's the point of this thread as I read it. Not recommendations, which should go in that other thread.

Thanks again to the OP, it's been very useful to a bunch of us.
[EVO 4G Accessories] Examiner19:
Car charger with HTC Car Dock? I have searched and believe this may be normal, but cannot find a post that explains this clearly.

I have a 1 amp car charger that shows up as AC power when connected directly to the phone; however, it shows up as USB when connected through the HTC car dock. Is this normal, or does the official HTC Car Charger work as AC power when connected through the dock?

The bottom line issue is that with GPS/Navigation going, the car dock power (showing as USB) does not keep up with the drain and I end up losing power when using the GPS/Navigation. I have the same result on vanilla Sense ROM and CM6.

I appreciate any thoughts on this.
[EVO 4G Accessories] dabigcheezze:
unfortunately it is a problem with froyo, whenever the phone is placed into dock mode, no matter what the charging input, it will only show up charging in usb mode, i have a homemade dock cable with pin 4 to ground, when i hook that up to my 1 amp charger it only shows usb, using a normal cable it shows ac charging, it has nothing to do with the HTC dock, it will happen whenever the phone is placed into dock mode, it also locks the vol output on the 3.5 jack 3/4 up....sooooo stupid.
[EVO 4G Accessories] Examiner19:
Strange behavior, but thanks for the clarification.

[EVO 4G Accessories] H4rry:
sorry to resurrect an old thread but I have just picked up one of these belkin chargers and the pin layout seem to have changed.

Could someone have a look and let me know if I still solder the same two pins.

Thanks
[EVO 4G Accessories] kellybrf:
you can still see the same 4 vertical dots towards the left/middle like the old ones. just connect the middle two

[EVO 4G Accessories] diomark:
An alternative is to purchase this cable -

It allows most usb ports that have ~1a power (including my laptop) to show up as ac power and charge much faster -

[EVO 4G Accessories] DevCake:
I'm late to the party but heard about this from another member. I was in the middle of figuring out the new Asus Transformer charger and cable, waiting for a part so I gave this a try.

I made a cable using a USB extension so I could also pass the power through a meter to see what the Amps were. Here is what I found

HTC EVO

Factory cable w/extension, pins not bridged, AC charger - 920 mAMPs shows AC power.

Factory cable w/extension, pins bridged, 1 amp car adapter - 820 mAMPs shows AC power.

Factory cable w/extension, pins not bridged, 1 amp car adapter - 720 mAMPs shows USB power.

So the AC wall adapter from HTC pushes 920 mAMPs, car adapter no mod 720 and with mod 820. My setup is only showing a gain of 100 mAMPs with the pin trick. More is always better but it's not double which is what I was hoping for.

Has anyone bridged an amp meter with other car adapters?

Thanks
[EVO 4G Accessories] DevCake:
Not the best angle, I don't see the 4 pins for USB. Find the 4 USB pins then solder the #2 & #3, the 2 middle ones. Where is the USB connector in that pic?
[EVO 4G Accessories] MCL1981:
Problem with your test is there is no equality. The charger is not going to draw the same amount of current every time. So your reduced numbers don't have any actual meaning to anything.

Could you post a picture of the setup you used to measure the current of your adapter? The adapter I have, just doesn't seem to be providing current I though it should even though both data pins are shorted. The EVO3D shows is connected to AC.

I have read on a different thread that someone increased their charge from 15% to 30-31% in 30 minutes by modifying their usb car charger, can someone please confirm on times for this?
[EVO 4G Accessories] barchamb:
I know this thread is old, but I just wanted to say thanks to the OP. Recently I bought a car charger from Monoprice that was labeled 2.1 A, but my Galaxy Nexus would only show USB charging. So, I bought a second charger from NewEgg that was also label 2.1 A as well as "Rapid Charging". It also showed up as USB charging. Frustrated, I did some searching and ran across this thread. I soldered pins 2 and 3 and both chargers now say AC charging. Thanks!

I got this to work on most singly usb plugs but I have a couple singles that this didn't work on and none of my dual usb plugs worked. I also tried the cable mood for the plugs that didn't work but still nothing. Any ideas, had anyone got dual usb plugs to work? It would be great to get this working with a dual usb so I could share the outlet without unplugging my phone.
[EVO 4G Accessories] -sandro-:
This is not really the same thing but I have one of those cheapo ebay chargers rated at 1A output, they are the ones you see on thousands of listing, they're all the same.

When I connect it to my galaxy s4 it shows a current of 420/580mAh! Way too slow! The phone doesn't show USB charing but AC. So what could the problem? People here say that those chargers do ouput 1A so I'm confused

So Joey helped me get persistant root this morning and I have been messing around with some root apps, and I thought I would share my findings so far:

OK, so here is what works so far:

AdFree Android (Free in Market)

Quick Boot (Free in Market)

Root Manager (Allows you remove sprint bloatware like Asphalt Demo, NFL, etc) (€1.99 in Market, approx $2.53 USD)

Shoot Me (Screenshot App) (Free in Market)

Root Explorer (£2.50 in Market, approx $3.88 USD)

CacheMate (Clears app cache) (Free In Market)

Titanium Backup** (Free in Market)

Here is what does not work:

Barnacle

android-wifi-tether

Personally, I cannot live without adfree, quickboot, and root manager.

**So I figured out Titanium backup does work, it was operator error. I just had to install Busybox.

From main app press "Problems ?" then press the button to download and install Busybox.

Here is a screenshot taken with Shootme. Notice the lack of the NASCAR app. Woot!

I don't know if it's the combination of apps that caused it but it appears setcpu doesn't play nice with the epic. Superuser and the binary seem to be working. Google voice kinda works. When you go into settings while installing it, there's no menu selection to choose between sprint vmm or gv. So I just *38 then after it hung up I did *28xxxxxxxxxx for conditional call forwarding from my real number to my gv number. It's driving me crazy that they switched the menu with the home keys when compared to the evo. You better bet your a$$ I gave touch wizz the boot in favor of vanilla launcher.
