Kastar 2-Pack Battery and USB Charger Compatible with Leica BP-DC3

In this review the Kastar 2-Pack Battery and LTD2 USB Charger is evaluated for photographers who still use older Leica DIGILUX models and need reliable spare power. The bottom line: this kit is for users who want two genuine-feeling 7.2V lithium-ion replacements plus a compact dual USB charger that can power two batteries sequentially or simultaneously via changeable plates. It is particularly useful when traveling because the charger accepts Micro-USB and Type-C input and reports charging progress with an intelligent LED indicator, making it a straightforward solution for keeping DIGILUX 1, 2 or 3 bodies running.

Key Features

• Battery Type: The included lithium-ion cells at 7.2V and 1700mAh give a full-capacity replacement suitable for extended shooting sessions.
• Dual Charging: The charger can charge two batteries at the same time, saving time when preparing for long shoots or travel.
• Changeable Plate: The charger includes a plate system that can be changed to fit compatible Leica BP-DC1 and BP-DC3 variants, offering flexibility.
• USB Power Input: With Micro-USB and Type-C input and a 5V 2-3A 15W input rating, the charger runs from common USB power banks and adapters for easy field use.
• LED Status Display: An intelligent LED dual charger shows charging status and gives a quick visual read of battery capacity while charging.
• Portable Design: The compact charger and two batteries are lightweight and easy to carry for photographers who need backup power without bulk.

Who It's For

The Kastar kit is aimed at owners of Leica DIGILUX 1, DIGILUX 2 and DIGILUX 3 cameras who want an affordable, compact way to carry two spare batteries and a charger that works from USB power sources. It suits enthusiasts and pros who prefer to travel light but need enough power for multi-day trips or long sessions.

It is less appropriate for users seeking factory-branded Leica batteries or those who require very high-speed professional charging infrastructure; while the charger is convenient and versatile, it is built for portability and compatibility rather than fast bulk charging in a studio setting.
