40 Ports USB Charging Station with Intelligent Protection

How to choose a USB charging station?

For me, I will start with the following: 

(1) Hand feel, generally speaking, a good charger will be heavier because there are more electronic components in the charger. 

(2) 3C certification. The full name of 3C certification is the compulsory product certification system.Each 3C logo has a random code behind it, and each random code has a corresponding manufacturer and product. If these standard USB chargers mentioned above can meet,even if it cannot be said to be perfect, at least it can be determined to be a good product that is safe and durable, and there is no need to worry too much in daily use.
