1, through online shopping! This is what most people like. You can choose to buy it in Taobao and JD.COM, but online shopping must be a genuine brand! Recommend a brand! Oshur car charger
2. You can also ask in some big supermarkets, such as CR Vanguard, Parknshop, Wal-Mart and so on. You can try this in the supermarket. It's also very good.
3. If you open your own shop, you can go to Alibaba or HC for wholesale! This is also to see genuine products and choose brands! Don't be greedy and cheap, make long-term high-quality products and ensure the trust of customers! Here I still recommend Oshur car charger!
thank you
