I'm Having Charging Issues - Are All Micro USB Cables Created Equally?

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.

Slow QI charging

Ordered a QI charger off Amazon (the same Lerway Chinese brand one everyone seems to get) and it's charging incredibly slow. Not sure if the app I'm using to record the charge rate is incorrect or I'm not reading it correctly but it says it's charging at only +200mA max sometimes as slow as <50mA.
Anyone else experience this?

What kind of power source you use to power the charger and what kind of cable do you use?
If you connect the charger to computer USB port it will not provide enough power for the charger. Same with cheap cables, like the ones mostly included with the generic QI chargers. You need a premium USB cable.
Also if you have a thick case on your phone it will diminish the charging current received by a coil in your phone.
Firstly check how much power and what current your charger gets, so instead of plugging the QI charger, plug your phone and check what amperage you get (I use Current Widget). If it's less then 1600mA (maximum amperage that N5 will allow from direct charging through cable) your charger is underpowered and you need to change socket charger to 2A one. If you're using 2A socket charger and still get under 1600mA then your micro USB cable isn't good enough.
Properly and fully powered Qi charger should charge your bare phone (without a case) at about 700-800mA.

Thanks for the info I thought I was going crazy.
No case so that isn't an issue.
I have the phone connected direct to a 3A charger currently and am only getting 995mA charge rate with the screen on and it looks like full 1.5A with the screen off. Maybe a defective QI charger?

Nope. Everything is normal. You just need a better cable that will manage to transfer 2A of current.
QI charger needs 2A input to give 1A output on a coil. Giving about 70-80% efficiency rate, your phone would be getting about 700-800mA.
Since your charger gets only about 1A input it gives about 500mA output. Therefore giving that efficiency rate, your phone should be getting about 350-400mA tops. It is possible that your charger has lower efficiency rate (some have about 50-60%), so the values that you're getting are pretty normal unless you use a premium micro usb cable, preferably with thicker, like AWG24 or lower (the lower value the better) power wires.

Might want to try these cables, a lot of people have had great luck with using them on Qi chargers. Don't know which length you would need, they have 3 and 6 foot cables. For the price, I'm ordering 6 6ft cables.

Charging from power bank

I heard about wrong quality USB C cables which can damage the phone but what if I use original HTC 10 cable with old powerbank?
Is it safety?

You'll be fine.

Used it today for the first time and it worked just fine.

Should work fine wall/car charger and third party cables are the problem. Tested some of them and met heat issues. The only one working flawless and without any issue, since I received them, are from Aukey. Just in case you want to order some more cables.
Sent from my HTC 10 using XDA Labs

That's complete nonsense, don't listen to sites like Android Central/Phandroid. They clearly don't understand how things work in that regard, so don't worry. I've used many of my USB A-C cables that are compliant from my Nexus 6P via a power bank (4 different ones actually), QC 2.0/3.0 and type-c chargers with 0 issues. Just don't buy a cheap no name charger and cable just like with any phone.
Here's a brief list of the brands of cables/chargers that work fine based on what I've personally used:
Choetech C-C/A-C/QC2.0/3.0/powerbank
Tronsmart C-C/A-C/QC2.0/3.0
EasyACC Powerbank/QC2.0
Incipio Car charger QC 2.0
Samsung QC2.0 wall charger
Google Type-C wall charger
I-Orange A-C/C-C cable
Anker Wall charger
Cable Matters C-C cable
Aukey QC2.0 powerbank

I've used the Anker 10000 mAh QC 3.0 Power Bank with no issues. Charges very fast and reports "Charging Rapidly". I also use the Anker Power Line USB-C to USB 3.0 cable with it.

I have an Anker 13000mAh power bank and I've used both the Anker and HTC type C cables and it seems to charge only when the screen is on. One the screen goes off the charging light goes off, then the screen will turn back on and start charging like I just plugged the charger in. It will do this over and over. I've had no issues with my older Nokia and the stock HTC wall chargers

i have xiaomi power bank which is have different volts with original wall charger volts , does it effect on my phone battery ? its ok if i charge it with this power bank?

I also use a powerbank having different voltage :
2.1 v and 2.4 v
Both are working fine and the 2.4v port is quicker

What charger for the Galaxy Tab S

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.

Charging cables amp issue

I bought from Aliexpress about 15 charging cables for me and 2 of my friends ... all of us have S8+ phones
The cable's description shows 5V 5A cables for Huawei Mate 9 10 P10.
The issue is these cables are not FAST charging our phones as needed.
Are there any requirements for the fast charging cable other than the current rating?
My understanding is the Adaptive Fast Charging uses 9V 2A (18w) while the cables are rated 5V 5A (25w) which means the cable bought should be superior to what is needed.
Does anyone have any explanation why these cables are not charging fast charging (Adaptive Fast Charging)?

Yes, they went bad. I buy cables from five below, and usually the type c 6ft works out of box. Then if you drop the cable so many times or do something, it stops fast charging. Now sometimes it doesnt work out of the box. Idk the construction behined the fast charge cable but the oringal samsung and more expensive dont seem to have this issue
