The useful moment in this short KUXIU S2 unboxing is attaching it to the back of my phone and seeing charging work through the case I am using.

That is a practical first check for a small magnetic battery. It is not a measurement of charging speed or proof that every phone-and-case combination will behave the same way.

## A compact pack with a simple indicator

I take out the matte-black unit and its USB-C cable, then compare the pack's size with the phone. Pressing the bottom button shows its remaining-charge indication.

I read the advertised capacity and wired and wireless output figures in the video. The different capacity labels refer to stated ratings, rather than a discharge test I complete here.

## The case stays on for the quick check

I attach the battery with a MagSafe case fitted and report that charging is working through it. I like not having to remove the case for that particular setup.

The [Gitryin power-bank first look](<https://pyrosoft.pro/blog/gitryin-10000mah-retractable-power-bank-ultimate-3-in-1-fast-charger-89dbb44f>) uses an attached cable instead. That is a different way to keep the charging pieces together, not a matched speed comparison.

## Read the offers with the right product

The description lists **kuxiuglobal** for 10% off KUXIU. It also has a separate Geeksoutfit link and **COLLAB1** clothing-store code; that second code is not presented as a battery discount.

I do not test battery chemistry, heat safety, travel approval or long-term endurance here. The first result is the attachment and charging check with the phone and case in the video.
