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

In this review of the Kastar 3-Pack Battery and LTD2 USB Charger the bottom line is simple: this kit is for filmmakers and mirrorless owners who need reliable, portable power without carrying bulky chargers. The reviewer found the pack useful for long shoots because the batteries are USB-chargeable, can be topped up on-the-go with a 5V 2A adapter, and the charger handles two batteries simultaneously while showing charge status with clear LEDs. For anyone shooting with a Blackmagic Pocket Cinema Camera 4K or 6K, or the Z CAM E2C, it removes one common pain point: dead batteries during runs.

Key Features

• USB charging: The batteries use Micro-USB or Type-C input to accept 5V 2-3A charging from wall adapters or power banks, which frees users from dedicated charging stations.
• Dual-bay charger: The LTD2 charger can charge two batteries at the same time, reducing downtime between takes for multi-battery workflows.
• Battery compatibility: Designed to work with LP-E6 style batteries used in many mirrorless and cinema cameras including Blackmagic and Z CAM models, offering broad utility across camera packs.
• LED charge indicators: Intelligent LED lights show red while charging and green when full, giving an immediate read on battery status without connecting to the camera.
• Portable design: The charger is compact and easy to carry, making it suitable for travel and location shoots where space is limited.
• Multiple input options: Comes with a Micro-USB cable and supports Type-C input for flexibility with modern power sources.

Who It's For

The kit is best for independent filmmakers, content creators, and photographers who use Blackmagic Pocket Cinema Camera 4K or 6K, or the Z CAM E2C, and value portable charging. If you regularly shoot away from AC power or prefer topping up batteries from a power bank between takes, this pack reduces the need to bring multiple proprietary chargers.

Users who require factory OEM batteries with camera-brand warranty or very high-capacity specialist cells for extended studio rigs should consider OEM options or higher-capacity third-party cells instead, because this kit focuses on convenience and USB charging rather than ultra-high capacity or manufacturer warranty coverage.

Pros & Cons

Pros

• USB charging capability allows charging from wall adapters and power banks for true on-the-go use.
• Charger supports two batteries at once, cutting charging cycles during a shoot day.
• Clear LED indicators communicate charging and full status at a glance.
• Includes Micro-USB cable and supports Type-C input for broader compatibility with chargers.

Cons

• Not an official camera-brand charger, so users who prefer OEM hardware may find it less reassuring.
• Charging current is modest (around 800mA per bay), so full recharges take longer than some high-speed proprietary chargers.
