Kastar 3-Pack Battery and LTD2 USB Charger Compatible with Leica

Our review looks at the Kastar 3-Pack Battery and LTD2 USB Charger as a practical power solution for Leica V-Lux 2 and V-Lux 3 owners who need reliable spare batteries and flexible charging. The bottom line: this kit is for photographers who travel or shoot long sessions and want the convenience of charging two batteries at once with USB power. The pack pairs three 7.4V 1500mAh lithium-ion replacements with a compact dual charger that accepts Micro-USB or Type-C input, and the review finds the combination saves time and avoids dependence on camera-specific wall chargers.

Key Features

• Battery Capacity: Each 7.4V lithium-ion battery provides 1500mAh of power, giving meaningful extra runtime for long shoots.
• Dual Charging: The charger can charge two batteries at the same time, reducing downtime between sessions.
• Interchangeable Plate: The charger includes a changeable plate to accommodate the Leica BP-DC9 battery form, improving compatibility and fit.
• USB Power Options: With Micro-USB and Type-C input and a 5V 2-3A 15W input rating, the charger works from common power banks and USB adapters.
• Intelligent LED Display: LEDs show charging status and approximate battery capacity so users can tell when batteries are ready.
• Portable Design: The compact charger and three spare batteries are easy to carry for travel or location work.

Who It's For

This kit is aimed at Leica V-Lux 2 and V-Lux 3 photographers who need multiple spare batteries and want the flexibility to charge from USB power sources while traveling or shooting outdoors. It suits hobbyists and professionals who prefer carrying extras rather than relying on a single battery.

Photographers who require factory OEM batteries for warranty reasons or who need higher capacity third-party cells beyond 1500mAh should look elsewhere. Also, users expecting a bundled Type-C cable should note the package includes a Micro USB cable and offers Type-C input compatibility but not necessarily a Type-C cable included.

Pros & Cons

Pros

• Three spare 7.4V 1500mAh lithium-ion batteries extend shooting time without swapping to a single power source.
• The charger accepts both Micro-USB and Type-C input, allowing use with common power banks and adapters.
• Can charge two batteries simultaneously, which shortens total charge cycles between shoots.

Cons

• Capacity is 1500mAh per battery, which is adequate but not larger than some higher-capacity aftermarket cells.
• The package includes a Micro USB cable only, so a Type-C cable may need to be sourced separately for that input option.
