KUXIU S2: A Small Magnetic Battery That Charges Through My Case
Attaching the pack to the phone and checking the charge indicator.
Article published November 4, 2026.
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 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.
