Chargers - Lenovo P2 Questions & Answers

What happens if I lost my Original charger?
Any specific chargers with certain sprcs I should look for?
They are all too slow.

Quick and Inexpensive USB wall charger?

I just lost my USB wall charger and realized my spares don't charge as fast as my previous one...
My previous charger had my phone at +700ma while in sleep, two of my spares can do 400 and one can only do 200!
One time I used a car charger that had me at +900ma in sleep so I would like to try and find a new wall charger that can get me +900.
BTW all the chargers I have used have said they are 5v 1000ma, so clearly I can't just go by the specs they list- I need a first hand experience of a quality charger.
So I open it to the forums. Anyone here have experience of a particularly strong USB wall charger?
I got a good Motorola one on Amazon for pretty cheap and it's been going strong for a while.

Well, you do need one that's 1000mAh.
You just need one from a reliable manufacturer that's not mis-labelled crap.
I'd just look for a quality brand. I got lucky with one for $1.50 on eBay but the seller isn't selling them any more.
Hm so I guess OEM or genuine name brands should reliably be up to their specs, then? Well, I guess I'm going to shop around for one that maybe says 1500ma or more because I believe my phone can take more than a 1A charger can give it, and it probably won't disappoint
Samsung note II have a battery of 3,100mAh, the charger is 2000mA(2A). but my i can use the same charger for my S2. so i guess that the amphere doesn't really matter. just that the higher the amphere of the charger, the faster it charge. But you sure need a higher amphere charger for bigger battery. Hope this help.

I've read that smartphones (at least android phones) have controlled charging circuits that will only allow for as much amperage as they are set to allow. So if you connect a 2000mA charger to the phone but it's limited to 1000mA then it will only draw 1000mA. However as I have noticed just because a charger says it can output 1000mA doesn't mean that it can. I have tried 4 different 1000mA chargers each with pretty different outputs- and if they don't output as much as your phone will take it WILL charge slower. The point of this thread was to gather information on which chargers are reliably fast and ideally economical ones (there's enough OEM chargers I can find for 10x the price of off-brand ones that would hopefully do the job right).

Chargers

Has anyone had problems with chargers not working? I have over ten different chargers but only one will work with my phone. When I 1st bout my phone I didn't have this problem. I'd there a special way I can calibrate my phone so it'll work with other chargers again?

I've had this issue with some chargers, but not all. Some HTC chargers no longer charge my phone (or they charge very, very slowy) and none of my kindle chargers charge my phone. I mainly use Palm Pre chargers (those things are beasts!), as well as the one I got from Samsung, and they work fine. I think it has to do with the Amperage and Voltage output of the chargers. Have you compared the ones you're trying?

I've had only one other work for me which I don't know what kind it was but I'm currently using the nokia usb charger. No car charger works nor does the original Sprint charger. Grrrrrr
Update: I cleaned out the usb port with a needle and I got 3 out of the 10 to work besides the 1 so I'm gonna go with that. Still no car charger to work but my 1 charger was on its last leg so I'm not complaining.............yet!
You can try Compressed Air. The type that is used on keyboards. Just be very careful. Also not all Chargers are equal. The Specs vary, sometimes greatly. Also the thread HERE has some info, even though it is not for our exact device.

Replacement/Extra USB Chargers / Cables

Saw a few posts here about cables, but not as much about the AC charger itself.
So as most of people on here have other USB chargers from other devices, can we compile a list of the USB chargers that work well with the Nexus 5?
And if possible, where to buy ones that will perform similarly, or better than the stock chargers?
I have been using the stock charger and stock cable exclusively, but I will try using my old devices' chargers and cables to see the difference here. For now, lets stick with talking about chargers only, and using the stock cable to keep the test consistent.
Does anyone have an easy way to measure this? There is the Battery Monitor Widget by 3c that seems to work well, but it does a + - current charge, it would be nice to know if there was a total charge indicator.
With my blackberry 5V 700mA wall charger, I am getting +120mA to +390mA.
Will edit more into this when I go home to do more testing.

The stock adapter MCS-01WR is pretty widely available for you to purchase. The problem is getting a source where it is authentic rather than a cheap copy. Also in terms of faster than stock charging the phone will only accept a certain amperage. It's for safety as well because it would the life of your battery.

So then my question is... does anyone know of a place where it is legit?

Multi-port Charger options (e.g. Anker, RavPower)

Seriously considering this phone, but there are a few aspects that are putting me off, one of those being the proprietary charge protocol.
With so many devices in the house, I currently have a 5 port Anker desk charger, and really don't want to be restricted to the Huawei charger to get anything better than "slow charging".
Has anyone tested charging using a third party multi-port desk charger and found fast charge 2A charge working? Has anyone tried USB PD via a USB-C port?
Also, please share experience of third party multi-port chargers that will NOT supply 2A charging so that we can rule out models.

I'm currently using choetech 3 ports wall charger. Maximum it could provide is 1.8A. Not quite as fast but fully charged within 2 hours. Good enough for me.

Does the charger provide the full 1.8A charge? You can check using this app - https://play.google.com/store/apps/details?id=com.gombosdev.ampere

Yes, that's how I know it's charging at 1.8A. But I don't really check the charge when it reaches something like 70-80%.

Question anyone actually get fast charging? What charger?

I am checking with app Ampere
I have a variety of chargers in my house - Ravpower, Anker, Aukey, Apple, Oneplus. All (except other phone chargers) are 60w, 65w, 90w, at variety of amps/volts that can easily hit 30w. However, I can't get more than 18w per the app of charging speed. Anyone else?

It needs to be a USB C-PD PPS charger.
Your findings are consistant. Hopefully they will update their charging behavior.

How do I check or know?

You'll have to look at the paperwork or online to see if a particular charger has that standard. I have looked around and there are a few chargers that have that standard (apparently they also work on the S21). A number of the usual suspects (Anker, Aukey, Google, etc.) have single port charges that meet that standard, but most of them are out of multi-port chargers that have that standard.
