I just made a portable usb charger for my g1..it works just fine for road trips and to power it all you need is a 9v battery and a usb cord.
See it in Action Here
Tutorial here
Under the Hood.
A 5.1 zener doide
a 330ohm resistor
female usb port
9v battery connector

Mad creative, nvr thought of this b4, I might have 2 make 1
That is pretty slick. I think that I will work on making one with and Altoids case like some that I have seen
Dude, how many batteries you need to fully charge g1?
Mad creative, props.
cool idea. Try hooking to your phone and carry it through the airport.
lol i dont know about the airport lol....and probly 2 if its off. ive noticed when i have it on charge it only keeps it from die.ing but ive used it like twice
are you dropping the voltage at all to charge it? I dont think its a good idea to apply 9V straight to the usb plug of the phone, unless it has a really good voltage regulator. USB + and GND is only 5V of potential difference.

fwiw but this built around a 7805 might be a better idea - http://www.instructables.com/id/Portable-USB-Charger-Version-2.0/ or another one along the same lines:

a 7805 would waste quite a bit of the power in the battery
This should work the same

True, mainly going for protection rather then replacement g1.. always open to suggestions of improvement though..
i regulated it with a 5.1 zener diode and a 330ohm resistor...so that brought the power down

Is this any true? I guess there was a reason why HTC devs put this, but I don't see any radical differences between the original charger and unoriginal ones...
Apparently it does charge it slower but if you use it, it will charge the battery like normal without doing any harm to the phone. Though it's best to use the oem charger.

I've got an HP 2.1 Ah adapter that I use with the DNA & does just fine. I think it might refer to the amount of amps being put out. I don't use any chargers less than 1 Ah.

Yes it is true, it was implemented with the software update. They used to simply check the data pins. Data pins shorted = fast charge (Current > .5 Amp), not shorted = slow charge (.5 Amp). This was done because the USB spec says devices can't have more than .5 Amps of current from a computer's USB ports. After the update they are checking something else though. I have several chargers that still charge fast but one dual charger rated at 2.1 amp that will now only charge slow. The charge rate won't be a problem if you're charging overnight but if you're trying to charge and use the phone at the same time you could potentially still be draining the battery but at a slower rate. The best example of this I can think of is someone like me who uses the phone in the car to stream music and navigate with GPS and screen turned on. Some of the custom kernels will override the charge current limit. This is no problem if the charger can handle it but is a potential hazard to your computer's USB ports.
Hello guys,
I'm experiencing a rather interesting charging issue. I've got a perfectly working 2000mA dual USB-charger capable of delivering full output when using one socket and sharing output when using two. Charging my friends i9300 with this set-up is no problem: I measured that the charger delivers 800-900 mA to the charging i9300, well below its maximum output. Things are not going that smooth on my phone...
Charging is extremely slow. In fact, when my phone is on it consumes more power than its receives. I'm using a pretty common case/battery pack (picture below). Connecting the charger directly to my phone, it delivers 80 - 150 mA. This is confirmed by a simple USB current/voltage meter and the Galaxy Charging Current Pro app. Charging through my case/battery pack delivers 450 mA according to the USB-meter and 300 mA according to the app (I'm assuming that the inefficiency of the case/battery pack draws quite some power).
Does anyone have a clue why the direct connection is yielding less current compared to the indirect charging process?

These phones draw varying power depending on several criteria, if too hot or nearing full charge then the current will be reduced. Custom kernel or mods can break it, also hardware fault are know in the usb socket and controlling IC.

Thanks, not sure why you're posting that quote. I've looked into several related topics and found this to be somewhat different, since I still can't think of a reason why direct charging is less effective than indirect charging.

Wanna buy an extra charger for my S.
Found many on ebay, but wounder if the chargers from other gears dose work ? Any one who tried?

I'd be interested to know as well.
They typically make them proprietary. I'd say no. Besides...ours isn't just a charger but a battery pack as well.
You can buy one on eBay, Search for "Gear S Cradle" or "Gear S Charger"

Lol , I'm thinking they meant JUST the cradle part and not the micro-usb wall charger like you are referring to??
Other cradles are wrong shape, and so will not work. Samsung has them for sale now on their website. I already have an extra one for work and gym now.

I would just match up the voltage and amperage from the original charger. Just about any micro usb would work, I even charge mine from the standard usb port on my pc if I have to.

but battery lifespan wouldn't be affected isn't it?
not that ive seen so far, I have a short cable coming off a kvm switch on my desk that I use occasionally, no issues with battery that I can see.
Bought a cheap chinese cradle and swap internal board and battery. Work like magic.

Hi everyone
After I've had to exchange my first two Mate 10 Pros within two days because of a faulty USB C connector (they wouldn't charge or keep a USB or headset connection), I've now been using the third one for 5 or 6 weeks.
Now, suddenly the phone won't really charge when plugged in over night, although it says charging.
I've made a screenshot of that, where you can see that it thinks it's charging, but is obviously not.
I've gone through all the apps, nothing has been keeping the phone awake, so it must be some system process, I guess.
In that case I was using a USB C Dock, so non OEM, but that has been working for weeks, and now it struggles.
As soon as I reconnect, it does start charging again.
Also, the phone won't accept any cable but the stock Huawei for supercharging .
Do you guys have similar experience?
This is the most expensive phone I ever had, and I'm seriously disappointed by how difficult and picky it is about charging...

Have you tried using the Huawei charger and cable? Do you still experience the same "not quite managing to charge" issues with them? There are plenty of sub-par cables and accessories available; I've in the past had many issues with el-cheapo MicroUSB cables.
As for fussiness, Huawei's SuperCharge is no more or less fussy than Qualcomm's QuickCharge - if the cable isn't designed for it, it won't switch into that mode. This doesn't necessarily mean that you have to use the original cable - just that you need to use a cable of decent quality (i.e., not poverty-grade speaker wire with USB connectors on the ends).
In order to get supercharge feature, you do need to use the original cable. Or at least a cable that support 5V charging ( oneplus does the same thing with their amazing Dash Charge ). That cable is different from other cables, so thats why it doesn`t accept any other normal cables. Are you using a case on your phone which blocks the type-c to not stick very well in the phone`s usb-c ? It happened to me with a random usb-c cable at work while trying to copy data from my phone on pc, and the original case that I got in the phone`s box, was blocking the usb-c to fit into the phone which resulted in phone being disconnected from the pc multiple times
Hello,
Can I use my usb-c laptop charger to charge my Poco F1 ?
This is the charger:

It will act as a fast charger or it will brick my phone?
Thank you.

No.You will brick your phone.
It does say that it can do 5V at 2A, so that is phone charging terirtory, but i dont know if the charger can detect the required power. Its risky but may work.
it'll probably work
but I've seen arduinos fry because they were plugged into the USB C port on the newest macbook while it was plugged into the charger
I often charge my Poco with my 65W charger. No Problem so far.
Even my OnePlus Wireless Bullets I charge with the 64W charger
Not responsible if your burn your house down or something lol
I use 65 watt lappy charger ....n it also show "Turbo Charger" .. no warning sign.... So no prblm to use i think
The phone and adapter should communicate with each other. It will pull only as much as the phone requests. I've used a Motorola 25 watt charger on my phone...and the measured pull is only 18W.
But it's better to be safe than sorry.
Even you use 500W charger if it will launch in Future. Poco F1 will gonna take only upto 18W power to charge itself.
you will damage your hardware! it supports 18w only!
you question can be viewed as, can i insert direct wire from wal socket to phone?
The phone is the one that decides how much power it wants to get. The charger just provides whatever it has to offer that's why these brick chargers have lots of modes set as it's output. There's should be no problem hooking your phone to these power bricks as every power needs proper handshake before delivery.
in my mi6 i used one from hp, works ultra fast!, but the phone is overheating, is dangerous, seems like to explote
if this was 10 years ago you will probably fry your phone, but nowadays smartphones are really smart. they will determine the best and maximum voltage/ampere to charge themselves.
