I'm thinking about upgrading my P8 lite to include wireless charging, but I'd like to put the charger inside the case.
Does anyone know of the appropriate test points for +5v and ground to the charger?
Thanks
I didn't open up my phone, but I don't think they have any??? Myself, I would just buy a cheap Qi charging adapter.
For ground you can scrap the PCB, for 5V just follow the battery connector, you'll have to remove a couple of screws maybe, I did it because I had to unplug it.

Hello
I have an iPAQ h5150 that has a damaged connector so I can't plug it in to charge it. It works OK otherwise. I have the charger with the male post connector and would like to solder in some wires and a female connector (e.g. from Radio Shack) just so I can charge it. Does anyone have information of how I can wire this thing up to do this. Alternatively, does anyone know how to charge the battery externally? There's 5 pins on the Battery that connects to the iPAQ, and I would like to know how I can apply the charger's output to the battery to charge it up. ANy schematic diagram availble would be appreciated.
Thanks
Mike
Is the charger terminals on the cradle damaged, or the slot in the Ipaq itself?
You can buy charging tips that fit this model on ebay for about $9.00, that slide over the barrel plug on the ac adapter. If the charging slot is ok you could charge that way.
I have been on the hunt for a charger for my car and home that shows up as an AC charger so that I can get a faster charge. After a bit of tinkering I have found that all you need to do to get ANY charger to show up as a AC charger is to have 5V on the standard USB + & - leads and simply connect the two data wires together. This will tell the phone that this is an AC adaptor.
I actually bought a cheapo 1A USB car charger from DealExtreme and it was supposed to show up as an AC adaptor but it didn't. So I carefully opened it up and de-soldered the resistors that were connected to the data pins on the PCB and verified that there were no more connections going to the two data pins on the USB connector (the two middle pins) and then put a small dab of solder across them. I plugged my MonoPrice USB cable into it and went to my car. Lo and behold it shows up as an AC adaptor AND actually charges at the full 1 AMP capacity!
Just wanted to share this with you guys. If people want to send me their chargers I would be happy to mod them for you (just pay shipping). I was also thinking about picking up a bunch of the USB 1A car chargers from DealExtreme, modding them, and then re-selling them. Would anyone be interested?

Thanks for that link! I didn't know if anyone else tried this yet. But I can verify that it works perfectly! The best part is that my car charger looks stock as I used 2-part epoxy to glue it back together.
i have said it before and i will say it agai , fast full 1amp charges a bad for your battery and do not allow proper charges this you get **** for battery life.
nice mods but not good for battery life

i heard you say that before, and i thought you were full of crap. after trying it for several charge cycles, it is plain as day. your battery charge WILL last longer from a slow usb half amp charge. seriously.
sometimes, however, it isn't worth waiting for. in a "non-primary" charging location such as a car, I can see the benefit in catching a quicker "top-off" charge.
I know your post is old, but THANK YOU MAN !!, i was having trouble obtaining only 100mAh from a AA-battery portable charger, modded a cable and now it's working so fine !!
Hmm, I could probably modify one of my short USB extension cables and cut off the data pins and keep that cable somewhere for cases where i'd prefer the turbo charge... Just snap on this usb extension cable (or maybe even an adapter) and boom you're getting the 1A charge
PS: my old WinXP box actually complains and shuts off the usb port if it sucks more than usual 500 mA, you would need to solder two usb connectors in parallel to fix that
I'm trying to figure out what the best way to implement a hardwired charger.. more specifically in terms of getting the most mA as I can. What I understand is that when the data pins on a USB charger are floating, the phone requests only for 500mA. When the data pins are shorted, the phone requests for 1A (or 1000mA). On any decent 5v ciglighter /wall outlet phone charger, I understand that the charger shorts these data pins, allowing for that full 1A charging capacity.
I plan to use one of these ebay 12v to 5v converters:
http://tinyurl.com/oogbhyn
..and splice a standard micro-usb connector to the 5v output, also connecting both data wires together.
If I understand this correctly, would this provide 1A to the phone? Does anyone see any implications?
Thanks!

In theory it should work OK.
I would recommend a few things. Make sure that dc-dc converter is easily accessible if you need to check it or smell a smoke in the car. Don't bury it too deeply where you will have to take too many things apart to get to it. I made plenty of mistakes in the past where years later wire cracks or connector is not making a good contact and I have to take the whole damn thing apart to get to it Also, I would STRONGLY recommend to add in-line blade fuse, like this: http://www.ebay.com/itm/Waterproof-..._Video_Fuses_Fuse_Holders&hash=item3f2dc85fa3
The last thing you want is to damage your phone if you get some in-rush spike. DC-DC converter looks ok, but you never know what could go wrong if it overheats and something shorts out. At least you will have a fuse to protect your 5V power supply line going to the phone. And since blade fuses are replaceable, you just pop in 1.5A or 2A, obviously don't use 10A that comes with it.
Once you done, comeback and post some DIY pics!!!
I was planning to use these add-a-fuse circuit extensions. I'll be sure to pick up some 2A fuses (supposedly the smallest fuse for mini-fuses)!
I want to actually hardwire chargers for two things into my car; my phone, to the left of the steering wheel dash, and a recently acquired dashcam right next to the rearview mirror. I drive a little Mazda so space isn't plentiful. The fusebox is to the left of the driver's left foot, so I planned to wire two add-a-fuse circuits; bring one up 2~ feet before the windshield pillar (phone), and the other along the pillar, over the headliner, where it would go to the 5v converter, and then bring the mini-usb cable where the headliner and windshield connect. There really isn't much I can work with..
Do you think that sun damage would damage the exposed cable? Perhaps it would be better to have an exposed female-usb outlet "installed" and use adapters to charge the electronics?

I have my Passport X50 wired through a-pillar. It's not usb, but 12V tapped off cigarette lighter internal wires so I can use another usb converter plugged into a cigarette lighter.. l was able to run the wire under upholstery of my GS350, but it was kind of tricky. I actually used credit card to push it in along the edge. Otherwise it would not look clean, and will be exposed to a sun - in my opinion sun damage is a problem. Perhaps get one of those cigarette lighter to AC adapters and use something like that 40W 5-port Anker wall charger I just reviewed?
I want to do the same, but for a dashcam.
Can I tap in to the power line that goes to the auto dimming rear view mirror and connect something like this to it?
Does the converter comes with a fuse or do I need to add an additional fuse?
Thanks in advance
I need to change my battery which is not a problem but while there I'd like to know if someone is aware of an option to upgrade my Z1 into wireless charging capable. I saw few options that are external using the micro usb but that doesn't tease me. Something like a replacement battery already made with the coil or something in parallel with a piggyback connector.
What about finding a coil that fits inside above the battery and solder the two cables to the micro usb port on the motherboard. Pin 1 vcc and 4 for identification. Or its pin 4 or 5 cant remember.
Do not solder directly to the battery. Batteries do have their circuit protection but i strongly recommend to also use the phones charge protection ie using the micro usb pins.
Whether it be an internal wireless receiver or external usb c receiver. Most external usb c receivers are at the minimum 3.9" tall which seems to be the issue.
You can, but...

You can get an Ultra Thin USB-C Qi Wireless Charging Adapter, and you could install it on the phone and keep it hidden and in place by getting a Razr phone case. I plugs into the USB-C charging port and the thin flat ribbon cable has a 90 degree bend to it. I used this coil adapter before on a convention smartphone years back, the only drawback is that your USB-C on the phone will be occupied by the coil. Wireless charging is slower than traditional USB-C charging.
Cheers,

I'm aware of that but the issue is most of these are at least 4" in height which would cover the fingerprint sensor.
Find the shortest version, and if need be you can cut it to streamline it.
The ribbon cable has some flex to it, and if you use a heat gun you can bend the flex cable like an accordion to reduce length. You could also diminish the height of the coil pack by cutting it. Since the phone has a glass back, and your "sandwiching" it with a case, there is no fear of creating a short when charging.

Wouldn't cutting it cause it to malfunction? Also, do you mean use a heat gun to fold it in half? Do you have illustrations?
I think he meant to cut the edge to make the fingerprint reader completely clear, but not to cut too much to avoid the coil, and I'm assuming he meant to fold the cable in half.
Another point besides the charging speed is the heat that the coil produces.

Just a few questions. Where can the wireless adapter in this picture be purchased (link)? It looks like the usb dongle is too long to fit properly on the phone since the adapter is shifted below the fingerprint sensor. Does this wireless adapter work good on the device without overheating?

Link does not open... Please supply some info to find it
I see this for Barbuda nut only comes with lightning connector... would need USB-C ＆ only 5v so... I would still buy one at that folds its level because I don't really care if it's fast charges because I leave the thing on the stand overnight and it may actually be better for the battery to slow charge.
I played around with this as well. I was able to trim the one I'll link below to the right size. The key is to not cut the coil, the rest seems like it can be cut without a problem. In the end I didn't like not having access to the USB-C port. But it was a fun pandemic project.

I'm a little late to the party here, you can solder in a wireless coil to the inside of the phone. The best coil I could find is this 7.5W (5V 1.5A) coil. There's a 10W (9V) option, but it would require addition circuitry to use in a phone.
The external plug-in solution is by far the easiest option, but it has too many flaws: blocks usb port, protrudes too much, fragile- must be kept inside a cover to protect it, most put out 2.5-5W, and it looks horrible.
Heres the link for the internal coil. If its unavailable at the time of reading this, on aliexpress, search for "7.5w wireless coil".
https://www.aliexpress.com/item/1005004119996834.html
And here's a youtube link showing installation. You can skip half of it. aim is to tap it to the ribbon carrying the charging from the usb.
It does require some understanding of basic circuitry and soldering... not for everyone.
Ive just bought the new Razr 2022, and will be installing it on that.
Just keep in mind that the RAZR has two batteries, and getting it apart isn't for the faint of heart.
It's also one thing to get apart, and another thing getting it back together..
Just advice, but definitely watch anything you can get your hands on before tackling, and good luck.
