Hi all,
I'm running into a strange issue with my Z1 Compact. I've just bought an Anker 40w 5-port USB charger, and when I connect it to my Z1c with the magnetic cable, it charges fine and everything is OK. However, if I connect it using a standard micro USB cable, it discharges at a rate of around 800ma instead of charging.
It's not just the Anker charger - I had a similar issue with an Arctic 4-port charger I was using previously. When I connect to the stock charger with micro USB, everything is fine and the phone charges normally. I'm running the latest build of SlimKat (it was happening with previous versions as well as on CyanogenMod) with unlocked bootloader.
Is the stock Sony charger different to regular USB chargers in terms of internal connections? I can't figure out why else this would be happening.
Stock charger has 1,5A and when you charge phone and at the same time you use it wont discharge. But if you have charger with max 1A or even less your phone would discharge while havy using
That's the thing though - the Arctic charger is rated for up to 2A per port, whilst the Anker is rated up to 2.4A per port, so it shouldn't be that.
Also, if I'm just using the phone normally whilst not plugged in, I might get a current drain of around 450mA from the battery. But if I plug it into one of these chargers over micro USB, the drain will be around 800mA to 1100mA. So it's not that the phone is using more current than the charger can provide; the charger is apparently actively discharging the phone.
I'm using Battery Monitor Widget Pro to check on all this. When I connect to the 3rd party chargers the mV and mAh flicker and jump about, but are steady over the magnetic cable or over micro USB on the OEM charger. Not sure what this signifies, if anything...

i bought that Motorola Rapid Car charger recent and have been using it about a week now. i've noticed that it doesn't seem to charge my Thunderbolt any faster then it did when i was using the Thunderbolt's USB cable with this USB car charger adapter.
so, my question is, why is it called "rapid" if it doesn't charge any faster?
and i suppose secondly, is there an actual microUSB charger that will charge the Thunderbolt faster?
they make one for the iphone that will fully charge it in 30 minutes so i know they are out there.

Maybe you should try this one.
Install the battery monitor widget. Monitor the battery for about 20 minutes while charging. Tell us what the charge current is.
Does the Motorola charger include a cable? If not, you may just have a weak cable. I have seen cheap cables with wire so thin that the charging current is no better then charging off a weak USB port.
My experience has been that the phone typically recognizes car charges as USB charging and uses a different charging profile. My solution to that is use a wall charger through an inverter or a kernel that doesn't use radically different charging profiles for A/C and USB.

No need for that.
Cut a small piece of aluminum foil. Carefully place it where it shorts the two center conductors in the charger. Plug the USB cable into the charger. Make sure the foil stays in place over the two center conductors.
It is now a high rate charger. (assuming it can put out 1 amp.)
The limiting factor is typically the usb cable itself. Most usb cables can't support the 1amp that is provided to it. Since you used the original usb cable that came with the thunderbolt (that's been "shorted" as mentioned above" ) it will be just as fast as the moto car charger. the 1amp charging rate that the moto charger charges at (i have one) and that the original one charges at are already "rapid". if you plugged a normal usb cable from somewhere else into the other usb car charger, it'd be much much slower

The stock charger is what shorts the connections. The cable is NOT shorted on the two inner pins because they are the data connections used for connecting your phone to a computer.

To meet the USB charging spec (which the TB uses), the two inner (data) contacts should be shorted with no more that 200 ohms.
But, the cable can also be an issue for rapid charging. The voltage drop for a 1A/5V source, across only .5 M of 28 gauge copper is ~220 mV. If you use a longer cable, there's more voltage drop. The TB likely current limits itself when the voltage drops below a certain threshold. Best to buy 24 gauge USB cables, if you can, especially if getting longer ones (monoprice has them).

I think its a matter of rated output current. BUT on the other side, the phone must be capable of drawing/using that much current. If the adapter is rated for more current than the phone can charge, the "extra" current wont be supplied.
Initially, Moto's standard car chargers output 5V and up to 550ma max (just like a standard PC USB port) so they didn't charge phones all that fast. Moto then came out with chargers that had higher current output, so they were capable of charging the phones "faster" than the original car chargers (but on par with the home/travel/AC chargers) and called them "rapid car chargers"..
Today, the current output on the Moto SPN5400A car charger is 0-950mA, and I've seen it sometimes referred to as "Rapid Car charger."
But as far as I know, Moto no longer makes/sells the lower current car chargers, and their web site only shows one MicroUSB and one MiniUSB car charger for sale, both of which appear to be of the 0-950mA output variety.

Just because someone makes such a charger for the iPhone, doesn't mean one must exist for the TB, or other phones, does it? I know the iPad uses a 2A charger. What happens if you connect an iPhone to that? will it charge faster? I guess that depends on if the iPhone is capable of drawing more than 1A to charge it.
I've not seen a "home" or AC charger that can charge the TB any faster than the Stock 1A charger. Does such a thing exist?
A proper car charger with 950mA to 1A output should charge the TB at almost exactly the same rate as the stock 1A wall/AC charger.
And btw, the Moto SPN5400A car charger DOES charge my TB in about the same amount of time that it takes me to charge my TB at home with the stock HTC charger. So while its not "rapid" compared to the stock home/travel/AC charger, its "rapid" compared to PC USB Port charging, or a plain lower current car charger.

I made a charger for my motorcycle. I use it as a GPS, screen on MAX, phone active with marginal signal. And I wanted to actually charge the battery at the same time. I did a lot of experimenting with the Thunderbolt. It would not exceed a pull of about 850ma from the supply, even at 5.5 volts. IMHO, you are wasting time looking for any charger over 1 amp.
Also, even with about 850ma in, not much over 500ma is getting to the battery. So a totally dead battery is still going to take between 2 and 3 hours to charge, no matter what charger you have. And twice that long if the charger looks like a PC USB port.

I was asking because of the OP's statement about knowing "they must exist" because they are out there for the iPhone.
I'm perfectly happy with my Moto car charger, and how fast it charges my phones.
I bought an OEM Samsung wall charger that charges at 1 Ampere. I started to charge my Zerolemon battery with it yesterday at about 6pm and here it is today and it is only at about 80% charge rate. Something is not right. I contacted the seller and they told me that the charger is from Samsung and it charges at 1 Ampere. It is either the charger is a knock off or my Micro-usb cable that connects into the wall charger is not the right kind.
Are there different variations of micro-usb cables that will work better? Some that allow more current to flow over them than others? My cable says that it is 28awg/2C. I remember when I had a playstation 3 I had problems with syncing the device with my playstation 3 with the USB cables I had bought. After tons of research it was the USB cables that were the issue. They didn't allow enough current to work properly with the PS3. I'm starting to wonder if I'm having the same issue with the Samsung Wall Charger. Is the 28awg wire gauge too thin?

- charger is rated 1amp but usually puts out less depending on the quality and efficiency of it. You won't get the fastest charge with a 1amp psu. Get yourself a cheap 2amp and have plenty of headroom.
- also, if voltage in your wall outlet is low (rare) that would affect psu output.
- yes super thin usb cables can be part of the cause.
- of course, if the cable is meant for PC charging, it will be wired in such a way, to not exceed 450ma (or so) whereas a usb cable or charger that is meant and wired for fast charge, will provide...for me...1150ma (Search/Research my past posts for more detailed info)
- also, most kernels, slow down the charge rate as the batter gets closer to 100% charge.
- a bad battery or custom kernel with bad code, could both affect charging speed.
I am aware that many of these dual USB port chargers dont actually charge any faster than 1amp.
Does anyone know of a robust dual charger that can swiftly charge my Z1, without having to turn everything on the phone off?
Also, will charging via the magnetic charging port and the mini usb at the same time, cause any issues or charge the phone faster?
If i am being stupid, please forgive me.
Take a look at the Anker chargers.
As far as I am aware you cannot charge your phone by simultaneously using the magnetic port and the usb port. Most likely the first one to be plugged in will take priority. Q

Thanks, I bought an Anker 150000 amp. It's dual. I was looking for an adaptor for a wall socket. Just worded my request wrongly it seems.
I have a Sony mag-cable, and a sony wall charger.. all are stock sony supplies bought directly from the local Sony retail store.
When I plug my mag-cable to the side, it charges it - as expected.
When I then plug the USB cable in, which is connected to the wall charger on the end, the mag cable STOPS working.
Using a voltmeter connected to the prongs on the side of the phone, the voltages dropped to near 0 as soon as the usb was plugged in.
I'm using a NUT's 4.4.4 with a locked BL and stock kernel/everything else.

I don't think you can charge them at the same time. I don't know much about them, but you might also look into 4 or 6 port chargers too.
I use the magnetic charger, it charge quite fast as. But I think the voltage limit for magnetic is 1 ma.
But for usb, I charge with Sony fast charge USB power bank, it's charging rate at 2.1 ma.
It's very speedy to charge. So I suppose that having a charger with 2.1 ma charger will fill up your battery better than 1 ma.
Anker chargers are really awesome, been using them for months...
What can you say about Lumsing power banks?
I have a couple of generic chargers I've been using with my note 2 for a couple of years. I realize these will charge slower than the samsung fast charge charger but is there any reason we can't use them or will they impact battery life (I would think they would increase battery life); i supect the answer is that they are fine but maybe battery technology has changed and there is some 'smarts' between charger and battery that would be damaged by these ?
No issue using your old charger except as you mentioned it won't be fast charging. I do not believe that the fast charging will hurt the battery. The fast charge only works for the first portion of the charge then the rate of charge slows to a trickle charge.
U can use any charger but i recommend to use any charger with 2amp output as it charges quick 40% in 30 mins insteas of 50%in 30 mins with original.
Original charger has two modes 9v and 5v it charges with 9v untill 50% and switches to 5v after that.
I think the unit i use is a sanyo 800ma 5 volt. I don't mind the slwo charge as long as it can't harm the battery. This is only used during travel and office; @ home I use the charger that came with the device.
You can definitely use another charger. Like said before it wont charge as fast. The adapter that comes with the phone will charge your phone at 9v instead of the normal 5v. If you use a different usb cable with the charger it will still charge at 9v. If you change the adapter, it will charge at the normal 5v whether you use the another usb cable or the one that came with the phone. The usb cable is just wires. The wall adapter is what determines how fast it will charge...
Hey guys !
I just bought an Galaxy Tab S (8.4) from eBay but it came without any charger/cable.
As it is a Micro USB port, there's no real problem, I have literally tons of usb chargers available.
The problem is that most the chargers/cable I used only charged the battery at a 0.3A rate (measured with an USB voltmeter + battery app).
I know that the original charger was 5.3v 2A. I tried with some powerful 5.0v charger (3.0A/Quickcharger 3.0 compatible from Anker) but no luck so far...
Is there a specific charger/specs know to work well with this pad ?
I'm using this aukey 3.0 compatible wall charger and so far it's charging as expected
How fast does it charge ? I only get 0.3A with this charger, which charges really slow...
0.3A is 300ma i am surprised the battery charges at all at that low rate, My 10.5" draws 1700ma from my third-party chargers according to my usb monitor, I have managed to charge it as low as 1000ma from my notebooks usb port, but you need a charge only cable as a data cable will not charge at all.
John.
