2100mAh 2-Pack Ni-MH Battery and USB Smart Charger - Compact Kit

In this review the reviewer looks at a compact power kit aimed at owners of older Panasonic camcorders. The Kastar 2-Pack combines two 2100mAh Ni-MH batteries with a small USB smart charger, making it a practical spare-power solution for users who need reliable runtime without carrying bulky gear. The single biggest reason to buy is straightforward: this bundle replaces worn camera batteries and includes an intelligent charger with both Micro-USB and Type-C inputs so you can top up from common USB power sources.

Key Features

• Battery Capacity: Each 6.0V battery provides 2100mAh of capacity to extend recording sessions compared with older, lower-capacity cells.
• Smart USB Charger: The charger accepts 5V 2-3A input and delivers 6.0V at 800mA, offering controlled charging for Ni-MH cells and reducing overcharge risk.
• Dual Input Options: Micro-USB and Type-C inputs give flexibility to charge from a power bank, laptop, or USB wall adapter when traveling.
• LED Status Indicator: The intelligent LED on the charger shows charging status and estimated battery capacity so you know when cells are ready.
• Compact Pack: The package includes 2 batteries and 1 charger, making it easy to carry a complete spare power solution in a camera bag.

Who It's For

This kit is best for owners of older Panasonic camcorders that use BP or HHR series batteries who want a ready-to-go replacement set and a compact smart charger. It suits hobbyists, event shooters, and travelers who need extra runtime and like the convenience of USB charging from a modern power source.

It is less appropriate for professionals who require OEM batteries with manufacturer service or extremely fast multi-bay charging workflows, and those who need higher-voltage or proprietary chargers should look elsewhere.

Pros & Cons
