Can I use other wall charger for SBH20? - Xperia Z Accessories

I just bought the SBH 20 today and i wonder can i use other charger or power bank to charge this SBH 20?
I see the wall charger come with the SBH 20 with input 150mA and output of 850mA.
was thinking to use XPZ wall charger with input 250mA and output of 1500mA, will it damage my SBH 20 if i charge it with XPZ wall charger? don't feel like bring so many wall charger when travel.
oh, my power bank is 7800mAh with 1 output port 1A and another 1.5A. can i use the 1A to charge?
Thanks in advance.

You can allways use a charger with higher Amps (mA).
Only importent thing is you have 5V.
Using an output with higher Amps sometimes reduces charging time.

i saw the power bank and other is 5.3V, does it matter?
how about using usb charging from laptop/desktop?
Sorry for being stupid, as I'm not IT expert.

If the device is properly designed 5.3V is no problem.

IIRC the stock wall charger is 1,5A (1500mA). It will theoretically charge the 2,3Ah battery in roughly 1h 32min.
The word "charger" is a bit misleading, because it actually is just a power supply. The actual charger is built into the phone. The phone will regulate the current (amperage) and charge the battery using the most suitable current. As long as the power supply is rated at 5V, it doesn't really matter if it's a 1,5A or a 5A power supply. The phone will take what it needs and nothing more. The power supply will not "force" any amperes into the phone.
Charging via USB from the computer will take longer, because USB ports on computers only give a maximum of 0,5A. The theoretical charging time will therefore be three times longer than with the stock wall charger. Repeated charging at such low currents is not recommended. It's best to use a power supply with enough current and let the phone do the rest.
In other words: You can use just about any Micro USB wall charger, as long as it's of sufficient amperage (not too low). I would also stay well clear of the cheapest chinese chargers. You never know what they will do.

3529 charges at 500mAh, this is close to the charging rate from a USB port (480mAh), so it will charge....but slowly. $1.16
3523 charges at 1000mAH, thats almost the same as the provided wall adapter (980mAh). $1.28
Shop4Tech has a car charget for $2.95 shipped but dont mention the charging current. I'll post back when they reply to my email.

The wall charger that came with my N1 lists the output as 1A (1000 milliamps) so it's identical.

It shouldn't. The quoted current rating (it should actually be mA, not mAH, which is a unit of electric charge or battery capacity) is the max amount of current it's able to supply. If the device on the other end doesn't draw more than that, which our N1s shouldn't, then it's fine. If the N1s WERE to draw more current, the power supply would probably break before the phone.
There's nothing wrong with having a more capacious power supply, and in this case, the car charger would charge our phones faster than the wall charger the OP bought.
Monoprice offers a 1000ma wall charger here, I just went with the 500ma to be safe. I will be using it at work while streaming music so a slower charger is a non issue.
I love monoprice.com The micro USB cables I bought from there look very high quality, very thick, and even has ferrite cores.
Monoprice is my favorite store to buy anything cables. Also the fact that they have thier warehouse 30 mins away from me, means i can pick things up same day. But all it not perfect, thier 3.5mm male to male cables are terrible. At least they have been since the last time i bought 4...
Thanks for making this post... I just picked up two 3ft micro usb cables, car charger, wall charger, S video cable, and 3.5mm to RCA cable... including shipping it came out to under $15!
Thank you so much for this site. I never knew about it till now.
A note about chargers and mAh ratings. My source is the Battery University:
http://www.batteryuniversity.com/partone-12.htm
They recommend for small batteries like cell phone batteries to charge them at less than "1C" (for the Nexus One that would be less than 1.4Amps or 1400mAmps) so these chargers should all be fine.
They mention that charging at higher currents can cause the battery to get hotter. Heat shortens the eventual lifespan of a Lithium Ion battery so "bigger" is not necessarily "better" in terms of chargers. A lighter charge can be gentler on the battery than a beefy charger.
They also mention that higher currents do not shorten the charge cycle by much. At higher currents the battery electronics typically kick the charge cycle into the "topping charge" state earlier and since the topping charge is very slow, it takes longer to get to 100% charge. A lighter charger may take longer to reach the end of the initial regular charge cycle, but it will turn over into the topping charge state much closer to full. Thus, a stronger charger will get you to the topping charge state (i.e. mostly full) quicker, but take almost the same amount of time to get to the really 100% full state.
I typically use a Blackberry charger on my phones - they tend to charge at lower amperage and so induce less heat. I also charge them overnight so even if the charge was slower it wouldn't really matter because 6-8 hours is plenty for any charger to get these phones to 100%, but likely the lighter charging isn't really taking much longer anyway. If I desperately needed to get my phone charged up very quickly during the day then I would definitely use the stock charger or a charger that was stronger, but still under the 1.4Amp maximum recommended current - but if you charge overnight, try using a lower amperage charger for long term battery health...
Charge rate is controlled within the phone. A 1400mA wall charger is capable of supplying *up to* 1400mA. There's no danger with using a higher rated wall charger.

True, but this is neither here nor there with respect to the points in my post.
First, the chargers that people are finding in this thread are lower power than that anyway so they can't provide enough to hurt the battery - whether or not the phone has the protections you mention. Perhaps the phone does protect itself, but the question does not matter unless you are talking about chargers that supply more than 1400mA which they are not.
My other point was that a lower power charger can charge the phone with less overall heat and extend the battery life. The phone will protect itself from damage, but charging close to 1C - while safe - doesn't help the battery last the longest it can.

Fast charging N1

It seems the only way to fast charge a N1 is with the supplied wall charger. Standard Micro USB chargers whould only allow at much as 450mA of charge current regardless of the adapter current capacity.
The bundled charger however, manages to push 900mA into the N1. I made a cut in the charger wires and measured the current draw to make sure.
Now.. I'd like my car charger to be able to do the same. There must be some hack in the plug of the N1 charger since there are only 2 conductors from the case to the plug. You can see that the plug is somewhat longer than similar Micro USB plugs..
So I tried to see if one of the 3 unused pins can tell me anything but.. they seem unconnected as far as I could tell. Diode measurement (to test for any digital part inside) also did not produce any results. The next obvious step is to take the molded plug apart but I'd rather not...
Does anyone have any clue as to what makes that plug so special?
And please - I did my tests with a bench power supply - not the car chargers - so don't go around telling me it has to do with charger current capacity.
Thanks,
Nir
are you sure the micro usb cords you are using are able to handle the amps? most chargers made prior to now, only push about 450mA, the G1, and N1 chargers i have push a full amp though. I just ordered a car charger that pushes an amp too. There is nothing "special" about the plug.

I beg to differ. All the cords can easily supply 1 AMP. It is the phone itself that decides how much to draw from the charger based on something IN THE PLUG.
I am an electronics engineer so do understand I know perfectly what I am talking about
And your 1A car charger does not supply anything over 0.45A to the phone.. you will see that if you are using the phone while it charges (say nav or phone call) the phone actually looses some charge albeit it being charged... This will not happen with the stock wall charger.
I have a 900mAh car charger that I use and it does in fact give 900mAh to the phone while charging. I can tell because I used a 450mAh charger at home before and it was slooow and I could drain my phone while charging it. With the car charger I can stream music with spotify, use the GPS, have the screen on full brightness and the battery % will still go up.
I also bought a new wall charger recently, which is 850mAh on the USB port and has a 350mAh charger for a loose battery as well, works quite nice.
Has anyone measured the voltage or put a scope on the output of the stock charger?
maybe stock charger has a slight variance in voltage over USB chargers or some signalling going on and this tells the N1 to take more current from it?
I would like a solution to this too I've seen my phone discharge while on a supposedly 1A car charger using co-pilot.

Forget the numbers on the chargers - what counts is what really goes into the phone and that needs to be measured with a current meter (test equipment). What you may think to be fast might not be that.
Original HTC chargers obviously do the trick of fast charging but this comes at a price compared to the $3-$4 garden variety on Ebay and the likes.
now I cannot help you with the electronics at all, but, my old HTC Touch Pro charger seems to charge the same as the one which came with the phone, is this correct?
(suits me if it is, as then I have a charger for home and work)
my blackberry bold 2 charger only says it outputs 700MAh, but both the google and htc chargers both say 1.0A

Yes, it is just anecdotal evidence as I don't have any equipment to measure it. But my phone no longer discharges when I use it while charging, which it used to do with the old charger I used. So while I can say for a fact that the charger I use now is faster, I can't say by how much (this goes for both the car charger and the one I put in the wall socket).
I ordered this charger a few weeks ago and it charges my phone as fast as the original charger. The label says 5v / 1200mA.

HTC Touch Pro = mini USB
Nexus One = micro USB
Not an engineering here, but I am guessing the phone not always drawing more than 500ma may be is to do with the charger itself.
There is this "fast charge" USB standard where a wall plug has the USB data pins shorted to indicate that it is a wall plug and hence the phone knows when to draw more power. So even if the charger is rated 1A, the phone might not know if it could utilize that if those pins aren't shorted. Try doing a quick Google on this ....
If someone can test if the stock charger that came with the phone in fact does have those pins shorted that would confirm part of this theory.
For all practical purpose - I used two cables/plugs with a bench adjustable power supply. Simple micro USB plug would only let me draw 450mA regardless of power supply voltage in the range 4.5-5.5V. Tried shorting data pins - nothing. Tried shorting spare pin to VCC or GND or any of the other pins - nothing.
Used original cable and plug - draws 900mA at voltages from 4.9-5.5.
So it's in the plug somehow.
Tried (very difficult) to see if the pins on the plug are shorted and all 3 spares (except for 5V and GND) seems unconnected.
Next step is the irreversible hot knife...
I'm bugged by this, too. I tested with my desktop dock connected to my car charger (which states 1000 mA): it loads slowly and my battery widget reports USB- instead of AC-charger.
Might it be that the phone tries to load more than 1000 mA at the beginning to be sure that it doesn't overload the charger? And if that fails, it falls back to 500 mA?
Could N1 use a simple logic of:
- always watch the voltage
- start drawing 500ma (or whichever is the lowest current as per USB spec)
- increment in say 50ma steps
- if voltage drops below 4.x V, back off and stay at that level
I just did a little test of my own. I have a Palm Pre car charger (actual Palm brand one labeled as 1000ma output) and I plunged my N1 into it on my way home from work. In twenty eight minutes, my battery went from 47% to 70%. Much faster than plugging into my computer, which is 500ma max. I don't have any fancy test equipment, and don't claim to know a whole lot about electronics, but seems pretty fast to me.
I have a 4-port 2A 5v USB charger, and connecting it to my Nexus OR Milestone with a MicroUSB cable (the one that shipped with either phone, or the one from my Kindle) yields painfully slow charging - it basically won't charge if you are using the phone.
Connecting the Nexus One charger yields fast charging on either phone - so it is not HTC (or Motorola) proprietary.
The Milestone comes with a 900mA USB plug, and connecting THAT to either phone with either of the MicroUSB cables yields fast charging.
I have another aftermarket 2 port 2A 5V USB wall charger (brand: T'nB) AND I have an iPhone USB plug, and both give fast charging on the Milestone, and I have not yet tried them on the Nexus One.
Breakdown (on things I've tried):
FAST CHARGING on Nexus One AND Milestone:
Nexus charger (either in the US (110v/60hz) or in France (220v/50hz) through an adaptor)
Milestone wall French USB plug (which I think is something odd like 850mA at 5.9v) with ANY microUSB cable (in fact, it seems to charge both of the phones faster than the stock Nexus One plug)
SLOW CHARGING on Nexus One AND Milestone:
USB plug on computer
One aftermarket 4 port 2A 5V USB charger (NOT a hub, only a charger)
FAST CHARGING on Milestone, untested with Nexus One
T'nB 2 port 5v 2A USB wall charger
Apple iPhone 1 port 1A 5v USB wall adaptor
Seems found the answer for Fast Charging N1
I had just do some test for Charging N1 With Original AC Charger , Other band USB Charger and PC USB charger.
1. Orginal Charger give N1 from 0% to 100% at about 2 hour and something.
2. The other band AC charger and PC USB Charger can only finish the same job over 5 to 6 hours.
The Fast Charging is Due to 5.1V (Measured at N1) and 5.2V(Measured inside AC charger). 0.1V Drop is due to resistance of USB cable.
The Slow charged is due to 4.8V (measured at N1) and 5.0V (measured on PC USB and Other AC Charger)
i.e. Original Charger mod from 5.0 V to 5.2V (about 10% increase in Voltage)
Looks my theory is correct then ? N1 watches the voltage and if it droops too much, it backs off the current.
So the key would be: get a charger than can maintain at least 1A @ 5.2V, use
a decent gauge, short wire from the brick to N1.
Has anyone tried a Blackberry charger on the N1? Will they work to full capacity as well? (They're on Amazon for a fiver)
Because the nokia charger is working
http://pinoutsguide.com/CellularPhones-Nokia/micro_usb_connector_pinout.shtml

I tested also HP charger + standard USB cable delivered with Nexus, and it is charching cca 1A.
Then I tested one noname Carcharger + standard USB cable delivered with Nexus, and also charging cca 1A.
I dismantle the noname carcharger and here is a result:
data line (pin2+3) is shorted and connected do + (pin1 ,Vcc) thrue resistor cca 630kOhm.

I have now tested with an HTC car charger for the HD2. It's fast charging (tested with Waze running, two bluetooth connections and playing mp3 - and it's still loading the battery, whereas before it would be stuck at the current percentage) and even shows AC power instead of USB.

[Q] Scoshe reVIVEII

Anyone using this charger with their Inspire4G?
I've tried using this charger with my phone, with several different cables, including the OEM cable. I can only ever get the phone to charge at the USB rate, not the AC charge rate.
Is this normal or is my charger defective?
http://scosche.com/consumer-tech/product/1921
I would assume thats because the 2.1A is ment for Ipad/Iphone/Ipod devices as they require a larger amp charge.
The 1.0A is ment for all other USB devices.
States that in the description.

when you go into Settings -> about phone -> Battery
It will show you the charging status. USB Charging typically is no more than 500ma. AC charging should be 1a.
I have an old AT&T brand car charger that charges the phone in "AC" mode.
This is were I am still getting confused.
What ROM are you running, Stock / MIUI / CM7 / or a Rom based off of stock ?
Is it 2.3.3 or 2.2.1 or 2.3.4 ?
I don't have those reading under battery status.
Anyways, I will go ahead and make the assumption that your car charger is busted and need to get it replaced.
This is were I don't get were you are stating AC Charging.
Alternating Current = AC Direct Current = DC
You cannot charge a battery " DC " with an Alternating Current " AC " period. Thats why all battery chargers reguardless of type convert AC power to DC.
Then only thing I can think of is maybe your phone can detect what type of charger it is connected to, displaying it as an AC Wall Charger or a DC Car/USB Charger.
Wall Chargers will generaly charge quicker then a computer USB Charger. Car charger typicaly charge quicker then most wall chargers.
Most Car chargers are very poor at controlling the amperage being supplied. They may stay at the right voltage but rest assured, you hit a 5v 2amp battery with a 5v 10amp charge and your going to fry it. This is the reason I dislike car chargers.
I can only see one of two problems with your Car Charger ;
1: the Car charger is bad
2: your 12 Power source port is not supplying the correct amperage that your car charger requires. IE:
I have the HTC Car dock for my inspire. It has an imput requirement of 12V 5 Amps to operate efficiently. The Power supply I have it plugged into is the 12V 20A Accesory Port in the front of my truck. It works just fine.
If your device requires say 12v 5 Amps to operate efficiently yet your car is only supplying 12v 1 Amp due to bad wiring, old fuses or bad connections your car charger will not charge at idicated levels.
The ROM is simply displaying "USB" if it is drawing 500ma charge, or "AC" if it's drawing 1000ma charge.
I'm running the 2.2.1, the LeeDroid_HD_V.2.0.0 ROM

Ok, so your saying that when you have the Car Charger plugged up and your device connected, your only getting a 500ma charge. When you use your old ATT Car Charger it shows 1000ma.
500ma = .5 Amps
1000ma = 1.0 Amps
If your not getting over 500ma out of your car charger then either 1 of two things.
Car Charger is busted, get it replaced.
Car is not putting out correct Amp - Voltage for the car charge to operate correctly.
Your old car charger could have different requirements and that is the reason it works, your new one could use a deifferent set and may not work.
Regardless, its not working in your car, try it in a friends and see if it works, if not then the charger is broke, if it does, then your car is broke.
Try usiing current widget while charging.. and see the readings
Inspired from my Inspire 4G using XDA Premium App
i don't know what you are talking about here. The 2.1 Amp option is NOT the AC charging rate. It is pretty clear if you look at the stock HTC charger that comes with the phone, it says it outputs "1.5 V at 1A".
And anyways...if you look at the product description on the link you posted, it CLEARLY states the 2.1A is for charging an iPad.

And anyways...if you look at the product description on the link you posted, it CLEARLY states the 2.1A is for charging an iPad.

I've used both ports on the reVIVE II, both the 2.1a and the 1a. Both only report the phone charging at 500ma

sorry...i thought you were referring to the AC rate as the 2.1A port, and the USB rate as the 1A port.

[Q] Charger Advice

Hello everyone,
So I have been trying to find the answer to what I am wondering but to no avail. I know that when using a charger that did not come with the phone it needs to have to same voltage to not hurt the battery, but I am unsure of the amps. I know for normal powering of things the charger needs to supply the same amount of amps or higher so that the item can pull enough power from the charger. However, phones do not need a certain amps to be powered by the charger. So I want to know if I can use any changer that has 5 volts, but varying amps. This is because I read that if you use a charger with lower amps it is better for the battery as it is not charging as fast increasing the life span of the battery, is this true?
Example: I have a LG G2 which uses a charger with 5V and 1.8A , but I want to use my nexus wireless charger that is 5V and 1.2A
Thanks for any assistance!

Hi, can I use this 4.75v 0.55A microUSB charger to charge the OnePlus 6? with a microUSB-USB type c adapter
Would it be harmful or good to load more slowly?

If it's not even 1A it probably won't be enough to charge it. Will likely use more power than what that will output. Would go with something that's 5V 1A or 5V 2A.

is not true, by multiple measurements I found out that phone taking less than 1A of 5V in the most cases.
Charging from ~80% phone barely overtaking 1A of power even from dash charger 5V/4A
