[Q] Where can I get a 1A car charger in Canada?

I bought this kit from e-bay and just got it in today, so have been trying it out on my drive from home <-> work.
The problem is, the car charger they supplied doesn't seem to be sufficient to charge the phone or at least keep its battery at a constant state when I'm using it as a GPS + Streaming music. On my drive home, I started at about 50% battery life. An hour or so later, I was down to about 35ish with it plugged in nearly the entire time. So clearly it's not pumping enough juice to the device
I was thinking of buying one of these from monoprice but I wanted to make sure it really would give me enough power. Obviously the power isn't that big of an issue, but I don't want to wait for it to ship only to find out that it doesn't help anyways.
Anyone tried the monoprice one I linked to, or one of the other ones from there? Or can suggest one to buy from elsewhere? Would greatly appreciate it, thank you!
*edit*
I should mention, I have a car charger uhh splitter thing...to split the one socket into two (one for an FM transmitter, and one for the phone). Could this be a limiting factor in how much power I'm getting to the phone as well? Or should the single socket have enough power for both devices?

I got a Kensington PowerBolt from Future Shop which claims to be 2.1 amps and I still drained the battery a bit when testing the nav. Possibly not as much as you but there is still a net loss. If the charger is accurate in its power then I presume my car isn't delivering enough power.
Any car charger that supports the ipad should be well above 1.0a. Whether it delivers that is a question I cannot answer.
Im going to test direct power charging while having the nav on to see if this thing can ever charge positive while in nav mode. I wonder if that has ever been done.

I am not aware of any car charger that is 1amp. What you are looking for is pretty rare

They are a little more prevalent thanks to the ipads higher power requirements for charging.
Future Shop has a few of them available now if you want. A little expensive though at $30+. I don't see the PowerBolt anymore which is too bad since that was a slim model that barely poked out of the socket.

This is completely untrue... did you make this up?
Griffin makes many:
http://reviews.bestbuy.com/3545/1207248/griffin-technology-powerjolt-car-charger-reviews/reviews.htm
Belkin and Kensington make them as well. Many are now 2.1A for the iPad.
But to the OP - a 1amp charger is not going to fix your problem in most cases. You need a cable with the data pins shorted so that the phone thinks it is pulling power from something other then a USB port.
A USB port only supplies 500mA - the phone will draw a max of about 750mA; but only if it thinks it is not attached to a PC. The wall charger shorts the data connection so the phone knows to pull more current.
I purchased a dual port (1A per port) charger at target or walmart, and then a took a USB cable and cut open the cable and shorted the data wires (not red or white - but the other 2). My phone says it is charging on AC power and charging keeps up with GPS.
It is possible that you could buy a car charger with the cable built in and the circuitry set to tell the phone to draw more then the USB 500mA, but I am not sure.
But know this; if the phone does not say "AC Charging" under settings->phone-> about - like it does when the wall charger is in use; then you are only getting 500mA.

I use a 2 amp 12v to usb adapter that is use for my ecig passthrough. Charges with bluetooth, streaming music, and navigation all running but charges slowly. Something like $8 on madvapes.com

Oooo that's interesting, didn't know that. So perhaps the issue could be that my cable is not supplying enough power. Are there instructions somewhere detailing how to short the cable?

You're going to need to strip a cable so so that you can get to the individual wires for each pin. You want to short pins 2 and 3 together which are Data- and Data+. Normally that is WHITE and GREEN

Once you do that, you'll have a charge only cable.

I think the shorted data pins are necessary, but 2 amps wouldn't be too much. Li-ion batts love fast short charges.

Are you saying that the phone will only draw a max of 750mAmps and so anything greater wont provide utility?

I thought there might be a limit on how much current you can provide at any one time.
On the original subject: I've started using a different car charger, and now have it plugged directly into the socket in my car. This results in it showing up as being charged by AC power in the settings -> phone status. However, it still loses power over time instead of keeping at the same charge or (ideally) charging the phone slowly.
I'm going to see if I can get my hands on that 2A charger and modify a cable, and see what happens then.
If anyone would like to see if the same thing happens to them, the main applications I have running are:
Google Navigation
TuneIn Radio (streaming from one of the DI.FM stations, and outputting audio to the headphone jack to my car)
I have 3g and GPS on, wifi off, brightness set to auto (have also tried with it set to the lowest it goes and the highest it goes, doesn't seem to make a substantial difference. Or even if it does, there is still a net loss in battery charge.)
It's on stock rogers rom, rooted, with no lag fix. And uhhh, that's all I can think of that would be relevant.

I've got an New Trent IMP1000, which is an 11.1Ah battery pack. It can output a max of 1A, but the phone doesn't see it as an AC charger, so it only draws .5A. If I short out the two pins so that it draws more power, how will the battery life of the battery pack be? Meaning how many phone charges will I get out of it? Will it be shorter, longer, or not have an impact?

You should still get the same number of "phone charges" out from the pack...they'll just be quicker charges afaik. i.e. if the pack took 4 hours to do a full phone charge before, it may only take 2 hours now. The same amount of power is used up each time though.

any progress?

Probably the cheapest USB charging adapter you will find

http://www.dealextreme.com/p/usb-da...able-for-samsung-p1000-black-91141?r=99999999

Hit that. Thanks!

does this do USB host?

Darn ... just last night I ordered the same thing from a ebay hong kong vendor for 6.50 dollars in total.
But on the side note, this comes with a switch to go from charging mode to external memory mode, right?

Yeah, this thing has a switch so you can go between data and charge only.
shaolinx - this does not do usb host. Only makes it so you can use any 5V source as a charger instead of always depending on the OEM charger.

So if I'm understanding this correctly I can plug this cable into my Droid X or Nook Charger and then into my GT without a problem? I just want to make sure I'm understanding correctly because this would make it much easier for traveling!

Maybe... Many of those are only capable of 1A at most, and might do funky things when the Asus tries to draw 2A.
Would work great with iPad chargers though.

The reVIVE II is listed as out of stock. The iPad version of it is widely available.
However, the iPad version can be made to work.
Open it up
Short the D+ and D- (middle two pins) of the 2.1A USB connector with a solder blob
Remove the resistor marked <I need to open the thing again to figure out which one - will edit tonight> - Looking downwards at the circuit board, with the 2.1A USB jack near the upper right, the resistor you need to remove is the second from the right edge of the board at the top.
After this, the Tab will charge.
As to the Chinese 2100 mA charger - I'm semi-wary after getting a bunch of "1A" Monoprice chargers that were good for 400-500 mA at most.

So, I finally received the usb charger adapter that OP mentioned here, and I can confirm that it works, though with some caveats.
You can toggle between charger mode and data mode, and both work fine. I especially liked it how with TouchWiz you don't get a blank screen even when in data mode.
The charger mode works as well, but kind of as expected, at about half the charging speed of a wall charger. So it'd take about 10 hours to go from empty to full charge, where as my wall charger could do it in 4-5 hours.
This seems best as a supplement at work, to add some extra juice while it lays idle on the desk, but not good enough as a main. Not sure if I would feel safe to travel just with this adapter.

FYI, the Tab will charge fine with lower amp chargers, it will just take longer to charge. Mine even charges fine with a 500ma charger. I have an in-line adapter that puts the Tab into charger mode same as the adapters posted for sale here.

Can anyone tell me what the charging setting does on this device? Does it just short the data wires to the female USB end?
My HTC phone will charge at 500mA from a USB port, but at 1000mA from the wall charger - I want to enable fast charging from a battery powered charger by shorting (or making low resistance) on the 2 data pins. Would this device do the job? My charging device specs state that it is capable of 1A charging, I just need to signal my phone that it is fine if it pulls more than 500mA.
This seems like it would be useful if it does what I think it does - 'data' setting would surely just put through all four connections, the same as if you unplugged this and plugged the USB connection directly into the computer, 'charger' setting hopefully puts less than 200 Ohm between the 2 data pins - can anyone confirm?

It does this, plus it also puts in a resistive voltage divider so the Tab sees approx. 1.2 volts on D+ and D-. Shorting alone is not enough for the Tab.
However, devices that expect only a short may or may not be able to override the resistive voltage divider. My Samsung Infuse expects a short, but will AC-charge from the Tab's charger and my modified iPad charger.

Your laptop may not be able to provide any more than 500mA through its USB ports, your charger probably has 1A (1000mA) output.

I'm not sure I understand why the top 2 and the 4th cables need to have a switch to change from data to charge. Doesn't a regular cable for the Galaxy Tab 10.1 allow either data/sync and charging? Does this have something to do with a feature of the Samsung P1000 that the cables are advertised for?

Need cheap car charger that charges full current

Can anyone recommend a car charger that is cheap and charges the unit like its on AC power? Some of the cheaper ones I've purchased in the past charged my phone like it was on usb power.
TIA!

Just open up one of your cheap chargers and short the middle two pins of the USB jack. A drop of solder worked on mine. There are only four pins, so it should be easy to follow and find a place on the circuit board to do it.
Once you get it done, plug in the phone and it will show that it's charging on AC, which means it's pulling 1 amp.

Plenty different ones available, but I use this one. There are cheaper ones, but this one is a quality build that charges at 1 full amp! Motorola brand for around $6 including shipping.

i've had android phones since year one. i've always bought my accessories from cellphoneshop.net and never had a problem

Dude, go to wallymart or somewhere and get an AC converter. I bought one with 2 AC outlets and 1 USB for fairly cheap at wallymart. You wont regret it. It charges my laptop, phone, and gf's phone just fine.

Monoprice has a 1a usb charger for $1.33. I was looking at it yesterday but don't have the link handy at the moment. They're also the best place to buy usb cables too.

Thanks for the original link!

The best car chargers I've found are the Palm chargers for the Pre. For some reason they seem to work much better than any other car charger that I have used. You just need to make sure you get model number 3453WW, because there is also an older model that looks the same but doesn't provide the full 1A charge.

Gonna stalk me some good chargers

so instead of starting my own thread.. thought id bump this up...
any new chargers out there.. for car... can be either the usb one (as i have the cig lighter to usb plug... )..or cig lighter..
just feeling out there if anything has changed..
we went on a LONG drive.. 376miles.. and using gps and my phone in my infuse dock.. it was charging.. but draining more than charging... by 1/2 way it was below 50%.... so the road i needed to take was super long so just turned phone off for a while...
was using the charger from my wifes incognito so i figured maybe that car charger didnt have enough A to it.. so bought a new charger from walmart.. and it didnt do any better...
thanks guys...
p.s. on my way home from work (1hr drive) im going to plug straight into my phone instead of the infuse dock and run the gps and see if it charges any different...

Even if the car charger says it can put out 2A the phone will only draw 500mah unless the two inner pins are shorted. Samsung does their chargers this way to identify to the phone that its plugged into a wall charger instead of a computer. (computers are only rated for 500mah on the USB port, although some can go higher)
You could open up the charger and short the pins, or if the charger is the kind where you plug your own cord in you can modify the cord itself. I have a "charging only cord" for when the phone needs a fast boost.

Hey, as the only verified genius here I wanted to share a great and cheap way to charge your phone. As i understand it you want the speed and current of AC out of your car's 12 volt dc system. They currently make something that works with ALL phone models. It is called an inverter. You just plug your stock phone charger into it. It will work fine for your phone but it wouldnt be wise to try use this it watch a 42" plasma tv. Here is one for 6 bucks that plugs in your lighter socket.

By the way, I can't endorse this product. I hope you get the general idea. As always you get what you pay for. Read the reviews and look for the inverter that you think would work best for you.

I would recommend getting the AC/usb adapter for an iphone or ipad, because they tend to run on a higher voltage (5v) than many cheap AC/usb adapters you can probably find off-brand one pretty cheap all over. If anything just make sure your adapter runs on about 5v. I just recommened iphone ones because there are more accessory manufacturers for i-products and you can generally find a wider selection of what you are looking for regarding this topic. I would check walmart first if money is an issue.

Note that most cheap inverters use a modified sine wave to gain efficiencies over 80%. Most phone chargers will work okay you might get a little buzzing. But you will often run into chargers, power supplies etc that will only operate properly on a pure sine wave inverter.

When using GPS on my HOX while charging at car, the phone usually drain more battery then the charge speed, meaning i see msg of less then 30% if i want to exit.
then i searched online and i found that if the Phone find the car charger it usually change charging to 500ma and not the 1000ma usually.
1. How can i check the charging Amp ? i wont to test few of my car chargers.
2. Can anyone recommend of good AC like car charger ?
i found some Kinsington and Griffin 2.1A ones, but i'm quite sure its for iPad and still be recognized as DC (0.5A)

its not AC or DC that effects the current output of the device
you simply need to find a car charger with a 5 watt (5 volt @ 1 amp) output
like this:
http://www.amazon.co.uk/Griffin-GC2...W6/ref=sr_1_12?ie=UTF8&qid=1338119269&sr=8-12
note the iphone compatibility is simply because they include an ipod cable, use the HOX cable and you'll be fine

I have to original one, and its 5v/1A
but i still read that DC identified charger gives 500ma instead of 1A in the AC one.

this is what i use, fast charging 1amp 5v

Many chargers designed for iOS devices will only charge non-Apple devices at 500mA even if the charger is rated at 1A. The Battery Status will read "Charging (USB)" instead of "Charging (AC)". You can often fix this by shorting the middle two USB leads in the charger (in Type A connectors, these are the data lines). Or you can get a charge-only cable which essentially does the same thing:
http://www.amazon.com/Naztech-Micro-USB-Charging-Cable/dp/B003VYBCAY

The problem you are having is that most OEM car charger manufacturers don’t appreciate how our smartphones work, and they neglect to short the two data pins out in your charger.
When you plug your official HTC wall charger in, the phone detects that the two unnecessary data pins are shorted out (as obviously HTC know to do this) and the phone will not limit it’s own charge to 500mA.
Use an unofficial charger, and the phone see no short on the data pins and so assumes it’s plugged into a PC/laptop USB port, and will restrict it’s own charging to 500mA to prevent damage to a motherboard.
Your car charger may very well be capable of dishing out 1A, but they manufacturers just didn’t appreciate what they need to do to tell your phone to start taking it.
I have had this trouble before, and there are a couple of options.
1) Only use official HTC car charger.
2) Take a spare charging cable, and carefully peel back the insulation. Then carefully cut back the screen. You’ll find 4 wires. Red, black, green & white. It is the green and white that are data. Cut these. The end of the cable that plugs into the phone, twist the white and green cables together. Insulate with electrical tape. Tape the cable back up. NEVER USE THIS CABLE WITH A PC/LAPTOP. But you should now find you charge at AC.
Been using a modified cable in my car charger for years, including with this HOX with no problems.

Check the "battery use" under settings>power.
While charging, it will say "Charging (USB)" or "Charging (AC)". If it is charging (AC), then your cable is ok, just make sure your charger's output rating is 5V x 1A.
Also, note that if your in a hot country, and your phone is under the windsheild, under sunlight, the phone would heat up & not charge (light will flash red).

wnp_79, can i just disassemble the car charger and make the bridge there ?

Yes. The data pins are the two center ones I think. Should be obvious add they wont be connected to anything else in the charger. Good luck!

I did this with my Griffin charger, was pretty easy to disassemble and solder the two middle pins together, now shows as charging AC.

Just purchased a PowerJolt on Amazon and noticed there were a few user-uploaded photos showing which pins soldered together. You are correct, it's the two center pins.
Interestingly, one buyer noted that their pins were already soldered together from the factory.

Thanks guys! Really useful info! I always thought it's my Belkin chargers fault

I think there's a bit more to it than simply shorting the data wires.
I'd try the official hox cable in the charger before messing with wires. For some reason 3rd party cables show as ac for me but the power level is severely reduced compared to the official.

Has anyone tried the HTC CC C100 or CC C200?
Bought the eBay car charger that was recommended earlier, but still get USB charging with it in my 05 Focus + the HTC charging cable
- Could my car the problem????
Anyway was looking at either the Griffin PowerJolt that was also recommended earlier or the official car charger
- Just want to make sure I get AC charging when using GPS!

I've got the c200 and it works at full ac speed as long as I use an official htc cable with it.

Bought CC C200 from Amazon (£4.69 from 3rd party seller, but fulfilled by Amazon)
Does give AC charging =)
Need to do some more testing, as I get AC charging using the "curly" HTC cable I got with the CC C200, with one of the other USB car chargers I have + want to double check that phone doesn't drain, using GPS even with AC charging
=)

From the testing done so far, even with AC charging - it doesn't provide enough power to run GPS (CoPilot), without losing charge & was running Core Control - using 2 cores
Going to test another car to start ruling things out =(

I use CoPilot (v8) quite a bit, mine manages to hold charge and stay topped up.
I think being in (not very sunny UK) helps as if the One X is in direct sunlight it will warm up, add charging and use and you have a recipe for heat.
Maybe try directing an AC vent on to your handset.

Install something like Battery Monitor and check how fast it is charging (when battery is < 80% full).
If it is < 500mah it's your charger.
I am using a Brodit holder and my One X charges when using Sygic, on full brightness and no tweaks.

Battery Monitor Widget Pro installed - monitoring seems funny, as it seems to update every few minutes, rather than "real-time"
Managed to get 1 charger / cable combination to charge AC and only just provide less power than needed (i.e. battery still went down, but a lot slower than other combos)
Still testing, but appreciate all the suggestions! Thanks!

Data cables quick charge

Man I bought 5 of the LG wall chargers that charge fast, and every data cable I buy my phone says is slow charging. Does anyone know what or where I can get a good one? These last cable arecawrsome, cloth braided wire, fits great, just slow charging...

I would like to know too
thanks!

I read this article recently about this issue and then ordered one of these to check my USB port outputs. It's weird but the USB 3.0 port on my laptop that is meant to be the one that you can set to be activated for charging stuff when the laptop is off actually has the lowest output compared to the other USB 3.0 & USB/eSATA combo 2.0 ports.
The article recommends The Practical Meter product which does the same thing as the eBay meter but apparently comes with connectors that trick devices into drawing the full 1A/[email protected] USB power. I was trying to find an alternative product (which I would not have to order from the US and be stung with import charges for) but I was not able to. If anyone knows of one please let me know.
Currently, I am charging my G3 through a USB 3.0 port with the eBay meter which states that it's drawing 0.21A/4.80V...I don't really know much about electronics so if someone could tell me if that is good or bad it would be appreciated. Lucky that I saw your post as I am reminded now that I must get a proper wall charger. BTW what is the model number of ur LG charger so I can see the info about it?

Hi, are these chargers genuine LG? The problem with cheap Chinese copies us that they do not include certain components by which you phone decides to use more power. Its the phone that adjusts how much power it is able to draw. For example using standart usb, which if you do you research on internet, only able to supply 500ma of power (0.5A) so the phone detects that and switches to lo power draw. Another reason sometimes for low power charge is that some cheap cables does not include full 4 cables inside??? I know! Crazy! They will not connect your phone to computer because they only have power cables inside and not data cables. Anyway try your original cable with these chargers and your original charger with your non original cables to work out what is capable of what. [emoji106]
And by the way, don't get fooled with that braiding nonsense, it's only to make it look good, but it does not define the quality. [emoji44]
I have been buying Samsung branded cables for a while now, and the all seem to do the trick, the only downside is their length - I want a long cable ant the are very short, but hey, on wireless charger it makes no difference [emoji6]

Hi, you should not incur any import charges to UK, since tax free allowance is £18 or equivalent in other currency. Also. 0.2a or 200ma is a very low charging current, it should take whole night to charge it. I think the charger does not have certain component to let the phone know that it is capable to supply more that a standard usb?. Why not to use you charger supplied with you phone?

Yes I know but often the postage takes it above that and then the VAT comes. I don't know why they include the shipping charges in with the cost of the item but I've been stung in the past like that. For international postage it's $8.50 so brings it to $28.49 or about £17.23 (xe.com) which is usually a little more generous than say Paypal so it's a little risky and might go over the boundary. In any case, I notice that they have UK stockists and also in Canada & Russia...but I have just ordered the PortaPow high speed adapter which I think is basically the same thing but cheaper and more practical and allows a 1A draw for charge.
The current cables I use are a 60cm Samsung U2 data cable with my PC or with the USB wall adapter, a 1.5m generic data one I got in Spain which is extremely well built and strong with a thick cable and solid connectors but I will try the one in the box now you mention and see if that makes a difference.
Using the 1.5m cable gives - Wall: 5.32V/0.79-80A & USB: 4.78V/0.27A. - (0.46A with the other USB ports)
Using the G3 supplied cable gives - Wall: 4.80V/0.80-83A & USB: 4.71V/0.49A - so this cable is better all round and on the USB port.
Using the Samsung gives - Wall: 5.20V/0.79-8.2A & USB: 4.80V/0.21A (The other USB 2 & 3 ports: 5.04V/0.47A)
It seems the USB port I always use and that is for charging when the laptop is off is unpredictable and has something possibly defective with it as it gives 0.45-49A with the G3 cable but much lower with the rest so I will keep the Samsung one for the PC but use the other USB 3.0 port and use the 1.5m on the USB wall adapter.
Do you know how much an actual wall adapter (non USB) gives out? Will it be around the same as a wall USB adapter or much more?

If I put the original dat cable on the wall charger units I purchased, no problem, if I use the New cables on the original wall charger I got with the phone, I get the slow charge message, so the problem has to be the cables

Actually, I just noticed but the LG cable is giving me the charging slowly message too on the other USB 3.0 port...I just plugged it back into the older one that was giving me 0.2A and now it's giving me 0.5A and no slow charge message! WTF is going on?! lol

Charging from a PC irrespective of USB 2.0 or USB 3.0 will always give you a slow charge. The factory charger charges at 1.8A compared to the max of 0.5A from a PC.

So does anyone know of cables that allow 1.8

All the stock cables yu get with phones now a days allow it. Just make sure they are the originals

I picked this one off Amazon for the G2 and worked great, sadly not available...

I'm trying to get extras...maybe LG has one

I guess I need to be the one that says any manufacturer's USB cable that works at all should be able to do at least 1 amp charging. USB spec is .5 amp, so that isn't surprising. Laptops that don't recognize something plugged into the port may not send the full voltage in order to save power, it depends on the manufacturer. The stock cable should easily handle 2.1 amp.
In short, the problem is much more likely to be the charging adapter or the USB port not putting out enough voltage, not the cable itself.
At least its not Apple which requires you to have iTunes installed to charge iDevices properly off of a USB port.

My HTC M8 Quick charger's USB cable seems to work fine with the LG 1.8amp charger but at least here in the UK the HTC charger is difficult to get find. So not the best answer to your query, sorry.
