Nowadays, we benefit a lot from portable power bank , but sometimes being threaten by inferior power bank that may even cause battery explosion. As an ordinary consumer, how can we check a power bank is good and reduce risks?

In the market, the energy conversion efficiency of top brand power bank is up to 90%. A good and safe power bank is decided on high-quality battery chip and circuit board, without which high energy conversion is just empty talk.
