OnePlus is leaving Europe and North America, as the company has recently confirmed. As a parting gift, it's offering a free AIRVOOC 50W magnetic wireless charger in the UK, Germany, Spain, and France if you do two things: subscribe to the Oppo newsletter on Oppo's German website, and link your OnePlus account to your Oppo account. So if you're interested, you need to act fast and get to the special page on the Oppo website for the UK, Germany, Spain, or France. The free wireless charger is not all that you can get from this campaign. These vary by market, so make sure you check the "Rules" and "Prize list" sections on the pages linked above.
