The difference is that the pure copper battery charger uses a transformer to step down to the voltage required by the battery, and charges the battery through rectification into pulsating DC. The electronic battery does not have a transformer, but uses electronic devices to step down and charge.
 The difference between pure copper and electronic battery charger
 Answer: The difference between the battery charger made of pure copper and the electronic charger is that the electronic charger is more sensitive. The electronic charger has a high technology content. As long as it is set, it can be charged with confidence.
 The difference between pure copper and electronic battery charger
 Pure copper has large impulse current and high cost. Intelligent electronics, low charging current, low cost
 The pure copper transformer is durable and not easy to be broken, but it has low voltage and current control accuracy. The electronic switch power supply can realize constant current and voltage charging, and has little damage to the battery. It can be charged without disconnecting the original vehicle connection line.
