Using 3rd party chargers

Hi, I have just recieved my TP2 and was reading the manual when I noticed that it stated "Only the AC adapter and cable provided with your device must be used to charge the battery". However I have two USB car chargers and two further AC usb ac chargers from previous phones (a MPX200 and a HTC 730) and several mini USB cables (standard not HTC custom ones). Is it safe to use any usb charger or cable, and the manual is just being pedantic or is there a good reason to only use the supplied charger/cable.
Thanks
Tom

I sometimes don't use the usb cable that comes with it. I use my others usb cable to charge it too. well as long as you checked the voltage before you charge. Like the car usb charger, I guess pretty much standard, as long as it is a 12volt :> Even at home I use different usb cable too.

In general it should be fine. Those warnings are always present, just like the comment to always use the maker's batteries. This is simply because
1. They want to make more money and they will if you buy original products from the phone manufacturer.
2. In the case of warranties, if you used a cheap charger with a defect, they are not responsible for the consequences should something go wrong. If you only use their cables and chargers, they can't really say it was your fault for using a knockoff/generic charger.

A friend of mine even uses his Blackberry charger to charge his Touch HD
When in doubt, check the output of the charger you are using: a standard HTC charger churns out 5V, 1A
USB cables are pretty standard so there isn't a big difference - probably except in build quality of the eletrical contacts and the width of the jack - I have one cable that cannot be inserted into my TP2 without a bit more force.

My TP2 Verizon (CDMA) is on the way. I use an "IGO" car charger and have tips for several phones and IPOD Classic. Interesting that most of my mini usb phones use the "a32" tip and the TP2 is listed as using an "A53" tip. May have a circuit for when fully charged. Both are mini USB.
I say an advertisement for an AC wall charger that says charges A"" usb devices. You plug the USB cord into it. Now why would that be safe for an IPOD, TP2, Motorola..... but not DC current????
Maybe they just lie!

The voltage is not an issue, al usb chargers deliver close to 5V but some deliver low current and the HTC phones prefer >500mA but even so less than this will just mean a longer charge time.
HTC recommend you use their cables/chargers as a safety measure because they use a non-standard connector with one flat side for their headset.
Two things can happen using a standard mini usb in this socket if you are not carefull.
a, A standard connector puts extra stress on the socket due to movement and can cause damage. (see prev device threads on Poss mini usb failure)
b, Some device specific usb chargers can have plug cross-connections to denote charger or data cable recognition and can subject data lines to constant 5V (not usualy a problem)
Basically they are issuing a disclaimer for the non-standard mini usb and trying to sell extra acc's at the same time.

[Solved] Phone Charger Advice!

Hi everyone i purchased new One X.
My brother has an LG P500.
They both have the same micro usb pin chargers.
Can i Use them interchangeably?
The P500 has output rating 5 V and .7 amps
while the One X has 5 V and 1 amps.
Its just that this would help me keep one charger safe in case when other one dies.
Obviously i wont use if there is some technical incompatibility b/w the ratings
EDIT:
Used the lower mA one. It works fine but charging toooo slow.
Now I charge my P500 using HTC one only.
Faster charging.

You can use it for charging yes.. It will charge slower though.
You could get some messages saying there is not enough current on the charger to keep the phone powered and charging at the same time.
This could happen when doing energy-intensive tasks with multi-core utilization.
Just for recharging, it shouldn't be a problem.

HTC say to use only their official chargers but generally you're fine to use any USB charger that follows the Battery Charging Specification and has the same voltage and is similar or better in current capacity. The statement to only use HTC chargers it just to cover HTC if you do decide to plug it into an off spec charger which damages the phone.
I use HP Touchpad chargers ([email protected]) as they're just generic USB chargers and I've got several spares. The phone is perfectly happy charging from it.

All manufacturers say that. But i always use whatever charger i have (nokia, sams ng etc). I just avoid using cheap chargers

[Q] Car charging low - USB mini -> micro problem?

Years ago I build a small powersupply based on a 2A 7805 for both my car and MC. They have served me well on several Qtek and HTC phones. The plug is a USB mini, but things evolving I have purchased an adapter from mini to micro. This setup have worked well with the HTC Desire Z.
After having upgraded to the One X, the setup does not work so well. The phone is charged - slowly, and if I use a navigation program (screen always on) the phone discharges. The LED does indicate that the device is being charged.
Why does the charging seem slower than normal in this setup?
Do I loose something doing the mini to micro conversion - and is the resolution to change the whole cable to a "true" micro USB?
BR Steen

If I use my phone while charging from my radio USB, a warning appears saying that the charging is not keeping up with the energy drain.
Maybe what was enough for the desire Z is not enough for this?
PD: I use a "true" microUSB cable.

As far as I know, a USB port is specified to deliver 0,5 A - and I expect that is the maximum your radio can put out.
The power supply I have made, can deliver 2A - which should be more than enough.
The question is if the pins used for delivering power through PC and related USB ports is different from the pins when using a 220V power supply?

It was already discussed on forums - you need pins D+ and D- to be shorted in USB cable to unlock possibility to charge with more than 500mA.
But beware if your charger can supply more than [email protected] - we don't know how phone handles this kind of current as official HTC chargers are only rated at 1A.

Thank's a lot colin_ktp. I will see what happens if I short D+ and D-.

This has been also discussed several times already. It doesn't matter how much current your supply is capable to provide, phone controls the current drawn from supply.

One Car and 2 motorcycle installations modified - All charging "AC" now. Perfect. Thanks!

[Q] Samsung Galaxy Sx family chargers compatibility

Hi,
I'm in deep sh*t, I lost a part of my luggage, where all the chargers for my phones and my laptop and the data cable for my SGS2...
In order to save on buying both a charger and a data cable (as on SGS2, they are separate), I'd like to ask, whether I could buy an
SGS4 charger ? Would it not do any harm to my batter on the long haul ? I know that the SGS4 charger is made of a USB data cable,
which is then plugged just in a socket connector...
Thanks!

my understanding is that so long as the output voltage is the same (5.0V) and the max output current on the charger is rated 0.7A (or above), you should be in good shape. I even occasionally use my ipad usb charger + usb data cable to charge my s2.

Yea most USB chargers should be fine. Heck, I'm using a $7 generic one I got from a local store because mine always break and it works fine.

I agree with Bigtonyman, using most microUSB charger is fine. Only output voltage must be 5V
I am charging daily my SII with: original charger 700mA (home), Nokia charger 950mA (parents) and occasionaly with china car lighter charger 1000mA, and from computer USB port.
I have my original battery 1,5 year old, and the battery time is similar to when it was new.

Dual port 2amp Charger - What should I buy

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?
