Kastar 4-Pack 1700mAh Batteries with LTD2 USB Charger - Dual Charge

Our review of the Kastar 4-Pack Battery and LTD2 USB Charger finds it best suited for photographers who need spare power and flexible charging options. The single biggest reason to buy is the combination of four 1700mAh lithium-ion replacement batteries and a dual-slot USB charger that can charge two cells at once or swap plates to accept different battery shapes, making it a practical kit for travel, event work, or long shooting days.

Key Features

• Battery Capacity: Each 1700mAh battery provides reliable runtime for mid-length shoots, reducing the need to hunt for outlets during a session.
• Voltage Compatibility: 7.4V lithium-ion chemistry matches original camera batteries so the cells work with compatible Panasonic and Leica models without modification.
• Dual Charging: The LTD2 charger can charge two batteries simultaneously at 800mA each, which shortens turnaround time between shoots.
• USB Inputs: Micro-USB and Type-C input options plus a supplied Micro-USB cable let users power the charger from power banks, laptop ports, or wall USB adapters for flexible charging on the go.
• Intelligent LED Display: The charger shows charging status and relative battery capacity via LED indicators, helping users know when packs are ready.

Who It's For

This kit fits weekend shooters, travel photographers, and owners of compatible Panasonic Lumix and Leica cameras who want multiple spare batteries and a compact charger that runs from common USB power sources. The ability to charge two cells simultaneously means it is useful for users who need a quick top-up between sessions.

It is less appropriate for photographers who require OEM-branded batteries for warranty reasons or those who need extremely rapid professional charging speeds beyond the 800mA per slot output; pros who need the fastest possible recharge may prefer higher-output chargers or manufacturer accessories.

Pros & Cons

Pros
