Kastar 4-Pack 1650mAh DMW-BLB13 Batteries and USB Charger - Dual

In this review the Kastar 4-Pack DMW-BLB13 replacement set is evaluated for photographers who rely on older Panasonic Lumix mirrorless bodies and need dependable spare power. The bottom line: this bundle delivers four 1650mAh lithium-ion batteries and a flexible USB dual charger that can power two batteries simultaneously or singly, making it a practical, travel-ready option for users of DMC-GH1, DMC-G1 and related models who want to avoid mid-shoot battery swaps and keep a compact charging solution on hand.

Key Features

• Battery Capacity: Each 1650mAh battery provides extended shooting time compared with typical single-cell spares, letting users shoot longer between swaps.
• Dual Charging: The LTD2 USB charger charges two batteries at once, which reduces downtime when preparing for a long session or trip.
• Flexible Input: The charger accepts both Micro-USB and Type-C input and includes a Micro USB cable so you can charge from a power bank or wall adapter.
• Intelligent Indicators: An LED status display shows charging progress and battery capacity so photographers know when batteries are ready to use.
• Portable Design: The charger is compact and lightweight with a reversible plate that swaps to fit different battery orientations for easier packing.

Who It's For

This kit is aimed at owners of compatible Panasonic Lumix cameras who need a small supply of spare batteries and a charger that works from USB power sources. It is particularly useful for hobbyists and travel photographers using DMC-GH1, DMC-G1, DMC-G2, DMC-GF1 and DMC-G10 series bodies who value portability and the ability to charge from a laptop or power bank.

Photographers who require OEM chargers with branded markings or support should look elsewhere, and those needing USB charging at higher wattages for many devices may prefer a dedicated higher-output charging station; otherwise this set covers the common needs of mirrorless Lumix owners.
