charger question - Huawei Mate 9 Questions & Answers

hey guys, I'm wondering if i need a normal wall plug for my mate 9 if PURCHASED at HongKong? or I need also need a voltage converter in order to have the Super Charge works efficiently?

Depends what you mean by 'normal' - normal for where?
The charger is rated for 100-240v so it won't need a voltage converter but you might need a physical adapter to suit your 'normal' socket.

[Q] DHD Micro-USB Charging question

So my DHD arrives tomorrow.
After reading about battery life, I want access to as many chargers as possible.
Can you tell me: Will my existing Micro-USB Chargers (Blackberry) be compatible with the DHD? I'm not sure if each unit will require a specific voltage / wattage?
Or can I just plug & play with which ever Micro-USB charger I come across?
Thank you & sorry if it's a dumb question...
Any cable will do fine. Definitely if you're charging through a PC since I've never heard of a phone/battery that can't handle the 5V it outputs (max for USB charging). A mains charger you can never be too sure with since it may have higher current/watt output, but I've really never let this stop me except that I'd avoid using cheap Chinese knockoffs.
It depends... microUSB connected to computer will be of course good, as it is hardware limited to 0,5A. External chargers are good question, but in my experience the phone/battery usually have a charge limiter so even if the charger does allow you to use higher current, the phone doesn't have to use all the power it can get.
For example i used the Nokia AC-10E charger for my Motorola Milestone since i bough the phone, and had no problems with it. And will use it for DHD too.
The official HTC chargers have an outpur of 5V/1A, so as long as your charger has the same output you should be good.
Nokia AC-10E has 1.2A, but as i said - that is the maximum it can give to the phone, batteries/phones have a current regulators so even if you connect a charger which can give you 2A @ 5V, nothing will happen - the phone will regulate the current which is used to charge the battery.

Optimus 3D car charger from Ebay

Hi All,
I bought a car charger from ebay for my phone and just had a quick question.
The output voltage on my indoor Optimus charger is 4.8v at 1amp
the car charger is 5 - 5.5 volts and 1 amp.
Do you think it's safe to use, being slightly higher in voltage?
Thanks!
Not an electrical expert here but ...
Considering USB is 5V i would say there should be no problem in anyway at all.
It would just be as bad as plugging it into your PC.
Most car chargers make use of the fact that most phones will charge @ USB power levels.
no problem

Sony Xperia Z Charging Dock Technical Question

Hi guys.
I have a bit of a tech question in regards to the charging dock for my sony xperia z.
I know how these smartphones can chew a lot of power and can go flat pretty quickly. so i charge the phone from a 240v power supply which has a 5v usb output rated at 2.1 amps. I know it charges faster than using the official charger which is rated at 1.5 amp as i have done my tests at work where i have the equipment to do so on my desk. I understand that it might reduce the life of the battery and probably not recommended as the battery is a lipo (kaboom).
I haven't seen one docking station out there which will charge at 2.1 amps!! So i bought 2 cheap knock-off charging docks off ebay in the hope i could use the charger with the 2.1 amp output. Both docks rated at 1 amp input and output. I was curious as to why they had a 1 amp input. So i opened it up and found a circuit. I redrew that circuit on paper so i could see what was happening. It is a simple circuit with a mosfet and transistor, which no matter what current you put through it, it will only allow up to 1 amp to pass through. Now why would they have that in there? Is it to make it usb compliant? why not just have a straight through connection to allow for higher current charging? Or do the charging pads on the side of the phone only support up to 1.8 amps (like the original sony dock) but they decide 1 amp is safe enough in case they have a faulty unit or whatever...i don't know.
I know it might seem like a stupid question but this raises another. Does the 2 charging pads on the side of the phone link directly in-line with the usb micro port for charging? or does it have its own regulation as well?
Basically what I want to do is modify the dock so it is a straight through connection, bypassing the circuit in the dock so i can plug my 240v mains adaptor to usb which outputs 2.1 amp so I can get that faster charge. My worry is if those charging pads will handle that sort of current or damage its regulator if it has one or even the usb micro regulator if it has its own? I know people say "it will only draw what it needs"......That statement is only true to those devices which have no battery and rely solely on a power adaptor. If the device has a battery, it will take what it is given, unless there is some sort of regulation to prevent over charging. Like I said, I have done my testing.
I was just hoping someone out there might have some more knowledge on this, specially in regards to the charging pads on the side of the phone. I don't particulaly want to ruin my $700 phone
Hi,
have you actually tried to do the modification? I was thinking about the same thing...

Safe to use Dual USB 2-Port Car Charger Adaptor?

Mini Bullet Dual USB 2-Port Car Charger Adaptor
Input Voltage:12V or 24V DC
Output Voltage & Current
Port 1: 5V 2.1A
Port 2: 5V 1.0A
Is it safe to use the above on any port? or charge 2 phone at the same time while surfing for T-mobile HTC One S?
thx
38 viewers but no one able to answer a yes or no.
In what way do you think it might not be safe?
I doubt very much if it will put out a full 2.1A from the blue port with two devices plugged in.

Thanks for the reply. I read somewhere that if using 2.0 above could damage the phone. I will order one since i need for my car. thx again

The device draws power up to what it needs or up to what's available. If it needs 2 amps that's all it will draw even if the charger can supply more. The charger doesn't force power into the battery.

Your charger will regulate what it pulls...think of it this way, would you put your phone charger straight into the cig socket? Of course, well that socket has to be rated for more than your adapter our else it could only put out what your socket gives it to begin with.

Use only one for charge at same time because it get warm and can harm our devices.
you can use the 1.0 amp port without a problem or the 2.1 amp port if only if you need a quick emergency charge for your phone

[Q] Can I use over 2A while charging my phone?

Hi
I really have no idea how much 0.1A is, so this might be a very dumb question, but here we go.
I know the phone is capable of 2A charging with the charger there is with it, but will it hurt the phone using more or less A? The volt is still 5V tho.
Because I have a powerbank, that is 1A and 2.1A in second USB port, so is it safe to use both? (If yes, I would of course use port 2, for faster charging).
Also, is this true for any (newer) devices? I mean, can I plug any newer device into any Amp and just enjoy faster (or slower) charging or do I need to use the Amp that was with the original charger?
Thanks in advance
The phone will regulate it, 2.1amp won't hurt it. I have a power bank that does 2.1 and use it all the time. You likely won't find a charger that will put out much more than that tho. Even for tablets with much larger batteries.
You're fine...
A stands for amps which is a measurement of current. Just FYI.
