In fact I'm pretty sure other places have recommended the same charger. I don't see how they connect it to the Quest 2 without some kind of converter. None of them mentioned the need for a converter it's all very bizarre to me. I don't know what's going on.
The seller states it doesn't charge the Quest 2.
