unreliable
Mobile phone charger is still authentic and reliable. Because everyone buys a mobile phone with a mobile phone charger, headphones battery and other accessories! Under normal circumstances, a mobile phone charger is enough to tube to the end of the life of the mobile phone battery. So we don't need to buy phone chargers on Pinduoduo at all! Mobile phone charger voltage can not be mixed charger!
I suggest you don't buy things from Pinduoduo, most of them are fake, the details will always be a little different from the genuine ones. The Huawei charger of more than 20 dollars is also a fake thing. It's better to buy a real one from a flagship store, it's not much more expensive, it's more durable, and you don't have to worry about charging your phone.
