The $69.99 5,000mAh charger is just 9mm thin — only fractionally thicker than the OnePlus 13 itself. It attaches magnetically for wireless charging, but you’ll need one of OnePlus’ magnetic cases — which start from $24.99 — if you want to use the magnets with the company’s own flagship. It’ll work with MagSafe iPhones out of the box though, and there’s always USB-C to fall back on.
