Samsung power bank

[AjayCA]

This is why the power bank drops the charge quickly.. 

This post is regarding the Samsung Fast charging 15 watts power bank.

This guy just killed physics 🤣. Its doesn't work this way.

It actually does work that way, except for the 9v thing he wrote about s10+ because phones again do a conversion after getting power from the adaptor. He is absolutely right in all the other facts and a 10,000 mAh battery is in reality near 7400@ 5 volts and 4111mAh @ 9v, there are efficiency losses of about 10 to 12 percent in the charge discharge cycle too so in no way can a 10000 mAh powerbank charge your 4000mAh s10+ battery 2.5 times.

I'm using Galaxy A72 (5k mAh battery) and a Samsung fast charge power bank (10k mAh battery).

After charging power bank to full, I'm only able to charge my A72 (0% - 100%) 1 time, then only around 5% of the charge would be available in the power bank.

[AjayCA]

If I charge my A72 with turning off fast charging option, then I could charge around 1.5 - 1.75 times with the same power bank.

That is intended behaviour, most people just don't know about this.

Why samsung doesn't make power bank or battery pack with capacity over 10,000mah, whereas other brands are doing the same & the latest battery pack released by samsung of 10,000mah capacity doesn't have any wireless charging pad...right now I am using samsung ecosystem with watch 4 classic, buds 2pro, watch d2b9 & s20FE5G & M51 Phones with Samsung 15W compliant 10,000mah wireless power bank. I am really looking for samsung to release power bank with capacity over 10,000mah since the same is not helping to charge the whole ecosystem while on commute. Also, when I saw the teardown of samsung 15W wireless 10,000mah power bank the protection and chipset used is top notch when comes to quality compliance & no other brand comes close to it.
