Magnetic power banks for the Galaxy S23

A lightweight magnetic power bank and case for the standard Samsung Galaxy S23 (6.1", SM-S911), with prices for Lithuania and the EU. Researched 14 Nov 2026.

How it works: the S23 has no built-in magnets and doesn't support Qi2. You need a magnetic (MagSafe-compatible) case for any of these power banks to attach. Wireless charging on the S23 runs at roughly 5–7 W. Charging over a USB-C cable is faster: up to 25 W from the Samsung, about 15–20 W from Anker and UGREEN.

Case

✅ Chosen

Ringke Fusion Magnetic Matte — Galaxy S23

€20.99 Amazon.de · ~$16.99 on eBay

MagSafe-compatible · 11-magnet ring · 2 mm back · 36 g · matte clear · Amazon ASIN B0BRQVSWYJ (base S23 only)

Thin, so the magnet sits close to the phone. A known brand.
Magnet is weaker than rugged cases, so not ideal for car mounts. Can yellow over time.

Budget alternative: Tech-Protect Flexair Hybrid MagSafe, €7.49 at priedaimobiliems.lt. No Qi2-certified case exists for the S23, because the phone isn't "Qi2 Ready". A MagSafe ring has the same geometry as Qi2, so these power banks still attach.

Real-world evidence

Engadget: an Anker MagGo 10K charged a Galaxy S23 Ultra fine, just not at Qi2 speed.
JC in the Shed: an Anker 622 charged an S23 Ultra from 69% to 100% in 1 h 21 min and held on firmly.
Maplee-tech: with thick cases (≥3 mm), Galaxy phones fall back to about 5.8 W. Keep the case thin.

Tip: buy where you can return within 14 days (EU right). On day one, check that the pack holds, the wireless-charging icon appears, and the phone doesn't overheat.
