Kastar 2-Pack 1650mAh DMW-BLB13 Battery and LTD2 USB Charger - Dual

In this review the Kastar 2-Pack DMW-BLB13 battery and LTD2 USB charger is evaluated for photographers who need reliable spare power for older Panasonic Lumix mirrorless cameras. The bottom line: this kit delivers two genuine-feeling 1650mAh Lithium-Ion replacements and a small dual USB charger that can handle two batteries at once, making it a practical choice for day trips, shoots, or travel where access to AC power is limited. It is most notable for its dual-charge convenience and multiple input options.

Key Features

• Battery Capacity: Each battery is 1650mAh which provides meaningful extra runtime for extended shooting sessions.
• Battery Voltage: The 7.4V rating is matched to Panasonic DMW-BLB13 compatible cameras so it works without voltage mismatch concerns.
• Dual Charge Design: The LTD2 charger can charge two batteries at the same time, reducing downtime between shoots.
• Multiple Input Options: The charger accepts Micro-USB and Type-C input and includes a Micro USB cable for flexible charging from power banks or phone adapters.
• Smart LED Indicators: Intelligent LED display shows charging status and remaining battery capacity so you can see progress at a glance.
• Portable Power: With a 5V 2-3A input and compact form factor the kit is easy to carry in a camera bag for travel or fieldwork.

Who It's For

This kit is aimed at owners of older Panasonic Lumix G-series models that accept the DMW-BLB13 battery, including GH1, G1, G2, GF1 and G10 variants, who want a convenient way to carry spare power without relying on a single OEM charger. It suits hobbyists, travel photographers, and anyone who frequently shoots away from AC outlets.

It is less appropriate for photographers who need the absolute fastest charging times or who require full OEM warranties and service; professionals who demand brand-new OEM batteries and manufacturer support may prefer original-brand batteries and chargers instead.
