220VAC plug-in charger for 18650 Li-Ion batteries

The IEC 60320 standard defines an international set of non-locking appliance couplers for connecting power supply cords to electrical equipment up to 250 V.

The specification ensures electrical and mechanical interchangeability across a wide range of devices. Connectors are designated by even and odd numbers, where odd numbers (C7, C13, C19) refer to the female connector and even numbers (C8, C14, C20) to the male appliance inlet.

Widespread adoption of this standard has enabled global hardware manufacturing efficiency, allowing a single power supply unit to work worldwide by simply swapping the localized cord. In modern data center architectures, the shift toward C19/C20 standards is vital to handle the increased power density of high-performance servers.

Key Features

• Global standardization and compliance.
• Class I and Class II equipment support.
• High thermal tolerance variants available.

Standardized by the International Electrotechnical Commission.

A charge cycle occurs when you use 100% of your battery's capacity. Lifespan is defined by total cycles before capacity drops below 80%.

Lifespan Calculation

Maintain the battery between 20% and 80% to maximize chemical stability and longevity.

Advantages

Controlled charging reduces heat and prevents lithium plating.

Note: Use original chargers for optimal safety.
