● The biggest difference between a charger and an adapter is that a charger only charges the battery, while an adapter can not only charge the battery but also supply power to the main unit;

●The lithium-ion battery charger is included in the power adapter function because it has an additional control circuit than the adapter. For example, the mobile phone charger includes three stages of constant current, constant voltage, and trickle charge, which is determined by the charger's design, while the charging control of the laptop is in the computer body. The adapter only plays a voltage regulator purpose and does not have the constant current and voltage limiting design that the above charger has.

● Lithium-ion battery chargers have current and voltage control to match the battery charge and can float after a full charge and then switch off.

● Adapters usually supply only a few hundred mA of DC power at around 5V and can only charge when combined with a charge control circuit (such as a mobile phone).

A lithium-ion battery charger usually refers to a device that converts AC power into low-voltage DC power and includes internal control circuits to meet the charging characteristics such as current limiting and voltage limiting. Lithium-ion battery chargers are used in various applications, especially in the lifestyle sector. They are widely used for common appliances such as mobile phones and cameras.

Lithium-ion battery chargers are used in various applications, especially in the lifestyle sector. They are widely used in common appliances such as electric cars, torches, new energy vehicles, and UPS power supplies. It generally charges the Li-ion battery directly, without intermediary equipment or devices.

The common power adapter on the market is a power converter that reverses the voltage, rectifies and regulates the voltage. The output is DC, which can be understood as a low-voltage regulated power supply in the case of meeting the power. It is widely used in telephones, game consoles, language repeaters, Walkman, notebooks, cellular phones, and other devices.

Power adapters are widely used in routers, telephones, game consoles, speech repeaters, walkmans, notebooks, cellular phones, and other devices. Most power adapters can detect 100 to 240V AC (50/60Hz) automatically.

Lithium-ion battery chargers should have current and voltage controls that match the battery charge and be able to float after a full charge and then switch off. Adapters usually only supply DC power of around 5V at a few hundred mA and have to be coupled with a charge control circuit (such as a mobile phone) to charge.
