This video was really helpful. I wish Samsung made something that would've helped us customers know if their item is fake or original. Others have different way to let people know and Samsung also should do something, as their products are more often copied.

[@UltimateDIY]

Glad my video helped 👍🏻

Excellent video, thank you. I appreciate how in-depth you went. I was able to grab two of these for 5€ each thanks to a recent promo deal here in France, which is pretty damn good for ~33 watt-hours of usable capacity. Something to add: the powerbank seems to be compatible with the "battery bypass" feature ("Pause USB-PD charging when gaming").

[@UltimateDIY]

Really cool! And from your info I tested and it seems it can even actually power a device while the powerbank itself is charging, so it can act as a sort of UPS.

[@MaxLebled]

@@UltimateDIY yes, although it drops down to a lower wattage if you do this (which probably drops the aforementioned gaming feature)

Hi, is it possible to charge your phone while charging the power bank? I think it's called "pass through".

[@UltimateDIY]

Hi. Yes.

[@obedal3112]

How do u turn it off?? Hello from milpitas, Ca, usa.. it's hot here

[@UltimateDIY]

It turns off itself if there is nothing connected.

Welcome. I would buy it again for my S23 Ultra, but no idea how it works with iPhone.

Am I test with a 25w cable to do it?

[@UltimateDIY]

Quite impossible to guess without seing myself, but I would test with other cables for sure.

[@Maven-d2z]

Thanks for the video, but what about wireless charging for Samsung phone?

[@UltimateDIY]

This model does not have wireless charging.

[@Maven-d2z]

@@UltimateDIY , thanks for reply man

[@UltimateDIY]

Welcome ✌🏻

[@southeastd.c5636]

What's the difference in the ports because as I'm charging the battery pack I'm using it to charge my phone as well

[@UltimateDIY]

I am not aware of any difference.

[@bilalmemon4398]

so in your opinion it is best or not?

[@UltimateDIY]

There is no best overall. There is just right for you or not. For me it's right.
