Product information

Description

The SmallRig 3821 Battery and Charger Kit provides a comprehensive power solution for digital cameras, featuring two high-capacity 2040 mAh Lithium-Ion batteries and a versatile dual-slot charger. Designed to match the dimensions of original equipment, these batteries include full decoding chips to ensure seamless compatibility without error messages. The charger is constructed from durable, fireproof ABS and PC materials, offering a robust build for demanding photography and videography environments.

Advantages

This kit offers significant convenience by allowing the simultaneous charging of two batteries, which is essential for maintaining continuous operation during long shooting sessions. The integrated LCD display provides precise, real-time feedback on charging voltage, current, and capacity, allowing users to monitor the status of their power cells accurately. With dual input options including a built-in USB-A cable and a USB-C interface, the charger is highly adaptable to various power sources such as wall adapters, power banks, or car chargers.

Suitable for

Professional photography and videography workflows
Extended outdoor shooting sessions
Travel photography requiring portable power solutions
Studio setups where multiple batteries are in constant rotation

When it may not be suitable

This kit is specifically designed for cameras compatible with the LP-E6NH battery standard. It will not be suitable for camera models that utilize different battery form factors or proprietary power systems. Additionally, users requiring extremely high-speed charging may find the standard USB power delivery limitations slower compared to dedicated high-voltage AC chargers.

Number of batteries included: 2

How to use

To use the kit, insert the batteries into the dual-slot charger. Connect the charger to a power source using either the integrated USB-A cable or a USB-C cable. The LCD screen will automatically activate to show the charging progress for each battery. Once the display indicates that the charging process is complete, remove the batteries for use in your camera. The batteries are designed to fit into the camera compartment exactly like the original manufacturer batteries.

What to consider before purchase

Verify your camera model is compatible with the LP-E6NH battery type
Ensure you have a compatible USB power source available
Consider the charging time required based on your specific USB power adapter output
