The OnePlus 13 is one of the best flagship phones you can buy right now, boasting top-tier design and performance. But if you want to embrace OnePlus’ take on MagSafe-style magnetic wireless charging, there’s a small catch. You’ll need to slap on a magnetic case to use the company’s new wireless charger. OnePlus sells official magnetic cases for this purpose, including the aesthetically pleasing $39 Wood Grain variant.
