Can I use my P2 charger with Rapid Charge at other devices?

How does the Rapid Charge feature work of the charger delivered together with the Lenovo P2? the Rapid Charge feature only works at my device when I use the charger I got with the device, using another charger like the charger from Samsung doesn't seem to give me that option, what does the charger do different from other chargers and is it harmful to use the Lenovo charger for example to charge a Samsung or Huawei device?

Not recommended! This is the first 24W charger, there is a chance that using it with devices different than P2 will cause damage to the battery. It will charge it, but the battery will wear out faster than usual.

The wattage is irrelevant. It just means it can output up to 24w.
What dictates how many watts are used is the device. So if a device can only charge at 1w (5v) then that's what it will draw from the charger.

Shure you can. I did it many times with: Xiaomi Redmi 3, Galaxy Note 3 etc. Each modern battery has it's own processor insisde in order to keep charging secure
Quickchargers are backward compatible

Quick Charge support ?

Does this phone support QC 3.0 or just QC 4.0 at India Only.
What Happens If I plug it into a QC 3 charger ?

I saw some news say that Xiaomi A2 lite is not sold in India? From what I heard then Xiaomi A2 support QC 4 in India and QC3 globally. Mi A2 lite only support QC 5V 2A. Not sure about these information.

What I've read the Redmi Note 6 Pro supports QC 3 in all markets, given its the same device on diff rom, it should support while it doesnt include QC 3 charger, Anyway I ordered mine along a QC 3 charger, at least it will not fry it.
And yest, it dont sell at India only the Mi A2 ("heavy")

Quickcharge 3.0 is supported by the SoC, so it should be supported unless Xiaomi disabled the functionality. I did see in one review that it does work.
Quickcharge 4.0 is only supported on the newer Qualcomm SoCs.
Quickcharge will not ruin your device, it acts like a 5V/2.1A charger unless the SoC tells it to charge at a higher voltage 9/12V.

I must test this..Official page says only 5V/2A charging..

qc 3.0 charger test with mi a2 lite
I bought qc 3.0 charger and made a test with my mi a2 lite. I did not see any difference with the 5v/2A charger.
Probably xiaomi disabled qc 3.0 support in mi a2 lite

I confirmed today with a QC 3.0 charger and a voltage/current meter. Device never went above 5V or 2A.
I wouldn't call it a deal breaker, this device will charge @ 10W(5V*2A) to a 14.4W(3.6V*4Ah) battery, so roughly a 2 hr charge time (1.25 hr to 80% and 0.75 to charge the last 20%).

Wireless charger
Does Mi A2 lite support wireless charging?

No It Does Not Support Wireless Charging.

When my Mi A2 Lite is charging it says 'Charging rapidly' and just almost exactly 2 hours from 0% to 100%. For a 4000mah battery that's not bad in my book.

So definitely there is only Fast Charging (5v2A) and no Qualcomm quick charge any version support. Hope it will be supported with new OTA bump to Pie

Mi A2 Lite will say 'Charging Rapidly' on the lock screen. I'm perfectly fine with the 2hr charge time, as 45-60 minutes of charging with this giant battery & 625 lasts longer than my Pixel XL ever had.

Can i charge my a2 lite with VOOC (4A) ?
Is it harmful for my device or is there any chance to blust the battery?

Question Can I use a 120w charger on RM6 Pro?

I just purchased a red magic 6 Pro to the uk. I know the Chinese version comes with a 120wat charger and rest of the world gets the 60wat or something like that. The question is if I buy a 120w charger will it charge at 120w or would it be limited to the 60w speed?

As far as I've researched, the global version of the redmagic 6 pro doesn't support 120W charging.
The Chinese version has a 4500 mAh battery, which is essentially 2x 2250 mAh batteries that are charged with 60W each in parallel.
The batteries of the global pro and non pro are both the same 5050 mAh type, so the maximum is 60W.
Btw, the included charger is only a 30W one, at least mine is. So if you want faster charging, getting a 60W brick would make sense. 120W wouldn't give you any benefit.

Question Warp Charge 30 not working?

Has anyone got warp charge 30 / 30w charging to work on their 9 pro? When I look at the charge speed using #8008 and logging the charge current with the screen off I never get over 1.2A or 1200ma. That is with the car charger and wall charger from one plus. My 65w charger will charge over 6A fine with the screen off. I tested the 30w chargers on my oneplus 7 pro and they work fine. I also noticed if I use a charger designed for PD my phone will charge at 2.0A / 2000ma. I find it strange the phone won't work in backwards compatibility. I actually get faster charging from my oneplus 5t charger that was only rated at 3.5A.
If anyone has a solution please let me know.

Because warp charge 30 can only negotiate up to the max of 5v. The warp charge 65 is 10 volts. The 9 pro phone uses a split cell battery which effectively splits and halves the incoming voltage and amperage for each cell so 10 volts become 5 volts each which would explain the much less than ideal charging speed.
Coincidentally USB-PD also can negotiate higher output voltage (I believe 9 volts) hence the compatibility to work with them.

I had considered the the 5v vs 10v but I thought one plus had mentioned the phone was fully backwards compatible. I really need to find a car charger that can charge the phone fast. I thought about buying the 50w OPPO charger but I cannot find one from any reputable place or even oppos site for sale. Right now I use my inverter in my work truck. If I could actually charger at 30w that would be fine for my needs but when using hotspot or GPS the phone doesn't even charge much at all when it only draws 1.2A. It takes multiple hours to charge 50% at that speed.

Never on the specs on the official product page for the warp 30 charger states it works with the 9 pro. Just settle on any 45+ watt usb-pd adapter and it'll get pretty close to warp 30 charger's max speed which would get you topped off in roughly an hour or more. Save yourself the headache and be grateful that's even an option as past OnePlus phones would only cap at 5 watts on any non OnePlus fastchargers.
PS, I wouldn't trust any marketing fluff coming from OnePlus as of late, they've been clickbaity and false hype inducing with bold but cleverly misworded claims since the inception of the 8 series and has been going downhill from there. My 9 pro is likely going to be my last OnePlus and likely last forray with android phones as a whole.

On the other hand..., wireless warp charger 30w from OnePlus 8 Pro works fine on my OnePlus 9 Pro.
I use it untill i got my 50w warp charger.

Question Charger for S22

I would like to know if the OnePlus 5T's charger will be able to charge the S22 or is it better to get the Samsung 45W charger or some other make with the future in mind?
There is also the Samsung Note 8's charger lying around but that seems to be a 15W compared to OnePlu's 20W and not sure the Note 8's charger will work.

All chargers will work. OnePlus' super fast charging won't work since that goes against your typical quick charging spec, but if it'll charge. The Note 8 charger will also work, but will charge at your typical 15w speeds.
Skip Samsung's 45w charger and just get a third party 25w or 30w charger since not even the 45w capable phones charge at 45w consistently and generally throttle down to roughly 30w.

25W charger is all you need. I have the Anker Power Port for my S22 Ultra and it charges from 20% to 100% in 80 minutes. A 45W charger is only slightly faster. Not worth the extra cost.

Im using the charger that came with my A20 to charge my s22 using fast charge. works well when not using the phone.
normally I charge my phone while sleeping. but today I didnt. when I went to bed it was at 95%, when I woke up it was 18%....

Thank you for responding.
I also have a OnePlus 5T 20W charger, wondering if I can use that.

But 20% to 100% in 80 mins is bad, when I'm in a hurry to go out I should have enough charge on my phone but with this 25W charger, it is not possible. So I'm going with a 45W charger because I used Redmi K20 pro with a 33W sonic charger, it charges 0-100% in just 40-45 mins!!!

I have the HyperGear wall charger works great.

Isnt the Samsung S22 (Base one) capped at 25W max capacity. Only 22+ and 22U support 45W charging.
I too upgraded from OnePlus5T, the S22 doesnt charge with it and shows 5 hrs to charge fully and for some reason, the battery was discharging while connected to the 20W OnePlus charger. I dont think its compatible, ideal and safe choice would be to go with 25W charger from samsung for 1299 if you do not have any previously owned ones.
