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.

And now here’s the catch: there are only 5,600 of these wireless chargers available, and they will be given out on a first-come, first-served basis. And that’s 5,600 in total across the four countries mentioned above. There is no country-specific allocation.

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. Oppo is also offering up various discounts on its products, excluding smartphones. These vary by market, so make sure you check the “Rules” and “Prize list” sections on the pages linked above.
