Note 3 usb charging overseas?

Hi everyone I just have a quick question
Right now I'm overseas and the power voltage of this country is 220 v .
I forgot to purchase a wall adapter to charge my phone but luckily my cousins here all have note 3 's
Is it safe if I just plug my usb (that came with the phone) onto their wall chargers/aftermarket wall chargers ?
Here is a picture of my setup

This is very basic. You should always check the charger or any appliances if it has/supports 110V-240V input. Be vigilant.

All chargers have 110V-240V input range, and any usb charger can charge the phone. Check the output amps of the charger, if its lower than the stock charger then it will charge slowly, if its higher than the stock charger then it would charge fast but could damage the battery life as well. Otherwise any USB charger will works fine just after market cheap one may does short-circuit or over heat issues.

Thanks everyone

Charging slow while phone says rapidly

Hey all,
A few days ago I've bought a secondhand nexus 6p. Overall I'm quite happy with the device, but I think I'm experiencing some charging issues.
The max USB current in Ampere never gets over 1800 mAH (while my mom's nexus 5x shows max USB current 3000 mAH with my charger) Also, I've never seen it charging with higher power then around 1400-1500 mAH.
I've tried my mom's nexus 5x charger, but I'm getting the same results. My phone actually charges faster with a regular 2 amp charger with a regular USB cable to USB c..
Also, while I'm doing nothing but having the ampere app open it discharges with - 1100 mAH. Is that normal?
Here are some screenshots:

What are your thoughts?

By the way: eve when the battery is down to 22% it doesn't charge faster..

Are you using the stock 6p charger and cable?

In my experience, Ampere does not work properly with the Nexus 6P. For me, it always shows Max USB curr 1800 mA and current in the 2100 mA range when using USB-C, even though I can see on my Kill A Watt that it is drawing 13 watts or more.

regardless of what the apps say, how long does it actually take (elapsed time) to charge your phone?

One plus 2 battery drain fixed. I got more than 7 hrs sot.

I used lineage os 7.1.2
Franco kernel
Dpi 400
Under cloaked to 960mhz
Cpu governor ondemand
Greenify with system apps
1.5 amp charger.
Here charger plays an important role if u use 1 amp and 1.5 amp charger u will see a great difference.
I got 3 hrs 40 min sot when its at 50 percent charge itself.
I used lte watsapp hike olx mxplayer....

Screenshot please.

Have you undercloack the low power cluster or the high perf cluster? what scheduler are you using?

Quick charge or not?

So, I had to change my original Xiaomi Redmi 4 Prime charger 'cause I lost it, and I went for AUKEY quick charger -> https://www.amazon.it/AUKEY-Caricabatterie-Caricatore-Samsung-iPhone/dp/B01AHYR04M, tempted by the possibility of charging my phone in less than the usual 2 hours.
However, I'm realizing now I probably did a bad move, since I'm reading many posts about how using a quick charger can reduce your battery life on the long run, some state they've used quick charge from the beginning (I mean right after they bought their phone) and they had to change battery or phone after one year and half more or less, not even able to reach more than 2 years, whereas some other claim they've always used a normal charger and their battery is as still good as the "old" times.
I'm thinking about sending the charger back and take a normal one, what's your opinion about it? Should I go for a charger with 2.0A in output?

R4P doesn't have Quick Charge compatibility in any case. It'd probably overheat like crazy even if it did.

Sure it has...

... see that circle around the thunderbolt icon? That means fast charging, when I charge the phone with a non quick charger, it only appears the thunderbolt. And it's also stated in the block screen, "Fast charging".

[MOD] Battery swapping tips

After buying three fake replacements batteries, declared as OEM, with capacity about 2000 mAh instead of original 3000 mAh, I decided to build my own custom battery.
Don't try to replicate my work. I have no responsibility for that.
Physical size of original battery is just about size of three 18650 cells next to each other.
But there is some limitations with using 18650 cells:
Maximal charging voltage is 4.2 V !! Most important issue! Solved with AccA application and limiting maximal charging voltage. Root required.
Need for welding cells together in 1S3P configuration.
Need for extraction and soldering electronics from old battery to newly welded cells
Total thickness (diameter) of cell. Solved by 3D printing custom battery cover.
Mounting cells securely to phone body. Solved by 3D printing battery base.
and many more
Benefits of this mod? Theoretically 10500 mAh capacity (3x 3500 mAh). But because of relatively early phone shutdown around 3.5 V, usable capacity is lower.
Battery base for 18650 cells:

Cells glued to battery base and to phone itself and finally battery cover installed:
Battery usage:

nice, how much you get compared to original for this setup? from 3,5V there is a lot of energy in 18650

About 6000 mAh, and that's sad I was hoping for like 9000 mAh. But for backup phone, 6000 mAh isn't bad at all ;-)
