How to charge battery without phone?

Hi,
Does anyone know how I can charge the battery without the phone?
I tried to connect a USB cable (red & black wires) tot the + and - of the battery (correct polarity, I checked on the internet).
But that doesn't make sense, battery isn't charged after several hours.
Does any1 know how I can do this?
Thx very much!
Pieter

Why not just get a charger from eBay or Amazon? Doing it your way, even if it sort of works, may do serious damage to the battery. And the last thing you want to do its smoke a lithium ion battery.

not sure if it safe/possible to it any other way then in the phone or a charger ment for it. there are universal ones and ones specific to the g2/dz that charge the batter without the phone. if you were do get it charging another way you may overcharge it, granted I believe the oem batteries should have a function to stop the charge @ a certain point but why taje the chance?

If you can afford to check on amazom.com. I bought an universal external wall charger from them and it came with 2 batteries as well.

Thx 4 your help.
I will explain why I'm asking this question:
the USB port of my Desire Z is broken.
I have ordered a completely new motherboard to fix this issue.
The board will be send to my homecountry from Hong Kong.
They will send it this week.
Until then, I have no Desire Z because the battery is empty and I can't charge anymore...

I can't remember the brand, but over at Staples there are these 7$ USB adapters for just bout any kind of battery , you just move the prongs to the contacts on the battery and slip it into a USB port (but given how our batteries have the contacts on the bottom instead of on the wide surface that may be difficult).
But yea I would say using an actual charger would be your best bet.

Where did you order your motherboard from?

here you go, something like this.

Portable battery charger

Anybody have recommendation for a good, portable battery charger that's not too big? I don't want those big square ones. I was looking at this one from this deal site...http://casepapa.com/deals/universal-2600-mah-battery-charger/
There's no brand, but it's only $13, so not much risk involved

Get a Pebble XT 5000maH you can get 2 or 3 full phone charges out of this before it needs charging again.

There are even smaller versions of that particular model called smart sticks. They have good capacities but charge slowly.

I can't live without my pebble, even my wife has twigged onto the fact I have one and it works with her iphone. I've known her go out with it in her handbag

I bought this one.
http://www.ebay.com/itm/39061239557...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It's trustable and good.
Bye,

I use this, it's cheap but it works well.
http://www.amazon.co.uk/TeckNet®-Du...0UH46YY/ref=cm_cr_pr_pb_i/275-7677557-9175212

First I bought a cheap external 2500 mAh charger with solar panel that it gave me enough juice to make many photos and keep internet on all day on travel holidays. But I bought an MacBook Air 11" and now I use it as external usb charger anywhere I go. It's to small to not take it with me when I make trip longer than a battery charge.
So if you have a mini laptop you can use it as external usb charger with a lot of juice for your phone. I keep always the MBA on a backpack or a messenger bag and the phone on my pockets with a charging cable connecting them.
And never felt since the need for another external charger.

Could Galaxy S3 use Qi wireless charger?

Anybody use it, please give some suggestion.

I use it on my S3. The charging speed is not that fast compared to USB, which I think is well-known. The back cover gets a bit warm also, and I have an Otterbox Commuter case as well, which gets a little bit warm also. It charges just fine through the case.
This is the one that I ordered, as it came with the charging pad and receiver for the phone.

Hope this helps!

I have one of the first gen receiver pads and it charges faster than USB but slower than AC.
check ebay. use search terms like "i9300 qi reciever"
just get the reciever pad.
the best charger pad imo is the nokia ones. they're regularly on sale from 20 -25 bucks for the most part. just do some searching online.

Any Wireless charging system or standard that has the two contacts to fit the contacts that are in the Battery compartment and fits will work....A wireless Standard isn't built into the phones, just the Transmitter and Receiver Coils....

QI wireless charging is nice... However I notice the connector from the QI receiver will interfere with the smart cover slot anyone?

look what i found^^

notice there is 2 connection on the smart cover.. the QI receiver use same slot...
You can find a quality charger kit on ebay... just to be safe... look for "Top Rated Seller" and someone with high feedback score to be safe..

oh, and because i'm such a sweetheart:
http://slickdeals.net/f/6904263-nok...e-in-black-or-white-new-bulk-18-free-shipping
18 bucks for a really decent charging pad. I have 2. one for my bed side and one on my desk.

This one works great with mine and I have the lifeproof case on it.

Of course you can not break yusb port, only one drawback - the phone longer charged

QI Charger stand. Difference?

Hello there fellers...
Is there any difference between last gen. wireless charging stand and the new one released together for S8?
Does the new one have faster charging speed?

If you mean this one,

I got one and did not like it. Unlike the Samsung Qi charger I had purchased for my car, this one seems to cycle constantly. So it goes on battery, and the phone discharges for a while, then it starts charging, then you get a full charge and it turns off and the cycle starts over. I found it too annoying to use.

Thanks. The new convertible stand looks great but is a bit expensive for now.
Edit: I read on a review for this model that "the correct power supply must be used for it to function properly."

If you mean that it should use the cables/wall plug that it came with, yes, that's true. I have two of them and without a quickcharging cable/cable, it doesn't charge/work as a quick charger.

Sindroid,
Here is the one I have been using
https://www.amazon.ca/Wireless-Char...24826&sr=8-1&keywords=spigen+wireless+charger
Works very well, not high speed but 3.5 hours for full charge and very sturdy. Also has the rubberized grip so very sturdy for the phone to sit on as well. Highly recommend it.

This looks very cool. Does it come with cables and a wall plug? I see "a" cable, but not sure if comes with all the necessary cables. I found it on the US site for $25 (guessing that's what it is at the exchange for CAD).

I'm using the new convertible charger. So far so good.

3D Printed Wireless Charger Stand

I picked up an inexpensive wireless charger ($12.50) to put on my nightstand but I've bumped my phone in the night a couple times so my phone didn't charge. I drew up and printed a little stand for the wireless charger to sit in and hold the phone while it's charging. This really isn't anything special and I'll be tweaking a few things to make it less bulky but I'm pretty happy with how it turned out.

Would you mind sharing the .stl? I'd love to print this tonight

Does the charger work with fast charging? As far as I've heard, fast charge only works with the pixel stand. Unless you found one?

This does not fast charge. I'm using it on my night stand and actually prefer that it slow charges overnight. I'm really not a fan of fast charging since things get so warm and LiPo batteries do not like heat.

Id be interested in buying two of them if you could make a square cutout for my charging pads. I can send you dimensions etc if you're interested.
