Charging via power bank - OnePlus 7 Pro Questions & Answers

Hi all,
I have a fast charging power bank (albeit not 30w..but good enough) like this https://www.amazon.com/gp/product/B07NYVQMHD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 . Is it safe to use the power bank for charging the OP7PRO? Is charging via a powerbank similar to power brick charging?
Please help..

Hi,
Your link is dead

Yes it's safe, the only thing is that it will charge slowly something about 8-9 watts.

[Q] Power Bank RAVPower RP-PB07

Hi,
I broke the charger of my Lg g3.
I going to buy a power bank instead of a new charger, in this case the RAVPower RP-PB07 (about 25€).
I wanna know if charging every day with a power bank, in the long period the power bank could cause bad effects on my phone or on battery? Is it the same thing that to charge a phone with a proper charger? :fingers-crossed:
i guess if you can buy the right power bank same electric flow with your original charger ,then it won't cause
any problem .but some people said power bank will harm the phone anyway .
Why not just buy a new charger? It doesn't have to be LG, Belkin or Hama are just as good. Just make sure it's a 5v 2a one so it charges at regular speed.
Anyway, a powerbank isn't harmful. It's still just a USB charger, regardless of the fact that is carries its own battery.

I though that it's helpful a charger that I can use alway and anywhere it's portables [emoji51]
And I read the feature and it's 5v and has 2 USB (1A and 2A)...the genuine charge LG is 1.8A!

The phone won't draw more than it can handle. (And If you use a 1.0A charger, it will double the time it takes to charge your device.)
Oh I fully apprpve of a powerpack. I don't go anywhere without my 15600mah X-Storm. But to use it as a charger replacement at home is a bit of a hassle, as you will still have to remember to charge the powerpack every day. For on the go it's a lifesaver.

Huawei Mate 8 Quick Charge.

Hi.
I have a question about Mate quick charge:
I found that Mate 8 has quick charge future. This future is in the phone or in the charger?
How can I switch between quick charge and normal charge?(there is a label on the charger "Quick charge", So for normal charge I should buy a new charger?)
Will quick charge harm the battery(In long usage and compare to normal charge)?

you can use a certified quick charger or normal charger. Its just the normal charger will take longer..
They have made the quick charge work in a way that it charges fast until it reaches 80%, and then gradually decreases to 'normal' up to 100% full, so in the long run it should have no harm to the battery.

there is no option. you can either use a QuickCharger or a normal charger..
But as i said with a quickcharger it Automatically changes the amperage as it gets more full, so as to protect the battery.

That's nonsense.
Any charger will do. Not every charger will charge the phone as fast as the original one though.
Using an Anker 5-ports charger here, without any issues, obviously.
Really!? Two damaged battery of HTC devices after use Samsung chargers about a mont. Personal experience!!!

OK, i don't want to argue with you. Just share opinion. And for some reason the manufacturer pay attention to use genuine chargers (attached pictures).

those warnings are for non technical minds.. because they done pay attention to technicalities.
Any charger will work, but you do need to take note of the output Voltage mainly...
Amperage will just mean how fast or slow it will charge..
- If i were to use a 9v 2A charger on a 5v 2A phone, i think it may cause harm.
- a 5v 1A charger on a phone 5V 2A, will just mean it will charge half as fast...
- just like when you plug your phone to computer USB port, it charges at 5V 500mAh (0.5A), hence why it charges slowly
Useful info for everyone.

Fast Chargers

Any ideas on where to get a UK plug fast charger? I hear the Mate 8 plug works for fast charging.
I guess I won't even be able to find a car charger as well so my old fast chargers are useless now!

I own a Mate 8 and I tried with the quick charger on P9 Lite and it's just charging normal
It's not a feature the quick charge on the P9 Lite. Hardware it's not there...
Oh I thought it was the same as P9 with hisilicon fats charge.but guess not...

Hi, I am planning to buy this phone and the only thing holding me back is the slow charging time with stock 1A charger
Your comment provides some hope that phone can handle 2A [emoji846]
Is this your experience/observation or you found reference of this capability online?

I found this
Although the Huawei P9 lite can receive two amps and 10 watts of power from a charger, Huawei includes only a one amp and five watt power supply with the P9 lite, which results in rather slow loading times.

If i understand for proper charging you need 2A charger and 2A capable USB. I ordered from ebay OEM Huawei 2A 5V charger and 2A 5V capable USB (Nikilin) just to test will it work.

Hi I've ordered a 2.4A charger (ravpower) but with ampere app I see it charges slower than the original one, the same using a 2.4 powerbank
Is this phone compatible with 2.0A charging or you need the original huawei 2.0 charger?
@Bumblecito can you please check how much charges with the mate 8 charger? Thanks

I spend a lot of time reviewing the dmesg output from the kernel and I have often seen mention an "FCC Limit" during charging. It is possible that the kernel is imposing a "limit" to be FCC compliant... Just a thought...

This is what I keep seeing in the log: https://github.com/Meticulus/androi...rivers/power/hisi/coul/hisi_coul_core.c#L2634
What I am seeing and measuring is that mine, the 3GB dual sim model, max current draw is 1.08 Amp.
This is the max the device will charge at no matter what if you connect a quick charge ... even a nuclear powerplant that can provide a billion Amps at 5V as long as the kernel or charging circuit is like now. A bit painful but I find the battery life to be good. Good enough so it won't be a deal breaker.
I've had phones that died while using the GPS in the car and on a charger, this one doesn't if you use a quality charger and cable.

Quick Charging Compatibility

Hi There,
Thinking of picking up the Honor 8 while I travel to the States. Just wanted to ask someone to clear up my confusion. So basically my question is:
Is the Honor 8 compatible with any Quick Charger ?
I know that most people have been saying that only the provided wall charger will quick charge the Honor 8 but , please excuse my ignorance/lack of knowledge here, if the provided charger is 9V/2A/18W , wouldn't a generic charger with those specs quick charge it as well ?
Also does the USB Type-C cable come into play with regards to the charging speed.
Thanks for any help. Just want to know because I'd like to have piece of mind that if I lose/break the provided wall charger I could buy another without paying the price of an Honor-Branded one.
Thanks

In Theory, regardings power supplies you're right.
The problem is more advanced: The charger provides 5V, (maybe even limited to 500mA) until the device handshakes successfully with the charger, and tells "hi there, I'm speaking hisilicon fast charging protocol. Oh, you do too? Great. How is the weather over there? Okay, enough smalltalk, please provide me with 9V, up to 3A, i can handle that without going into a puff of smoke".
The charger then reassures every 100ms or so, that the device connected is still the same... and keeps providing 9V
With a QC based charger, it might go "hi there I'm speaking hisilicon fast charging protocol. Oh sorry, i don't understand QC2.0. I can provide you with this legacy charging protocol". And the charger should recognize that it can provide 5V,2A - which will help, but won't be quite as fast as quick charging...
Lets see when Anker or some other company bring out a dual-lingual charger...
You should go with huawei's charger.

Thank you for your question regarding the Honor 8 and it's capabilities with quick charging. Your phone comes with a 9 V 2 A high voltage quick charger. It also supports 5 V 2 A chargers. Make sure you buy an official Huawei 9 V 2 A charger; unofficial quick chargers will not work properly. If you need a quick charger, you can buy one from Huawei Vmall or official Huawei experience shops. NOTE: The FRD-L02 shipped to the Indian market comes with a 5 V 2 A charger. (NS)

I think you should use stock charger....
Otherwise it will decrease the life of your battery..also can decrease your battery backup..
But the company said it supports fast charging upto 18 watts. And the one I talking about is 17.5 watts charger. Also the stock charger came with smart phone charges very slow 3.30 hour to be fully charged.

It may damage in long term but now a days batteries are designed in such a way that they will suck only power as per there design and architecture. Even if you use 10A charge it may damage but battery will just use the rated power it designed for. It wont accept entire 10A.
You may use 9V/2A charger..if using high rated one, it will just make little difference not charge in half time
Thank you all for your reply and your precious time...
Read this http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries when you'll have 10 minutes like to dedicate on reading these declarations on li-po batteries, to understand better good and bad points that rotates about fast charging personally i never used it, it'd be possible through a custom kernel but in my case, 40-50 minutes to obtain a 40% (that is also what i use daily, more or less...) is more than enough.
