Kastar 4-Pack Battery and LTD2 USB Charger Compatible with Pocket

In this review the Kastar 4-Pack Battery and LTD2 USB Charger is evaluated for filmmakers and photographers who need reliable, portable power for cameras such as the Blackmagic Pocket Cinema Camera 4K and 6K or the Z CAM E2C. The bottom line: this kit is designed for users who value the convenience of USB charging and the ability to top up multiple Canon LP-E6 style batteries on the go, and it stands out because it combines a USB-powered, dual-bay charger with four spare batteries to extend shooting time without adding bulky adapters.

Key Features

• USB dual charging: The LTD2 charger accepts Micro-USB and Type-C input and can charge two batteries simultaneously, which reduces downtime between takes.
• USB wall and mobile charging: The charger uses a 5V 2-3A input so batteries can be charged from a wall adapter or a portable power bank when shooting on location.
• LED indicators: Smart LED status lights show red while charging and green when batteries are fully charged, making it easy to know battery state at a glance.
• Interchangeable plate: The charger can change plates to accept different battery plates, adding flexibility for users with multiple battery types.
• High compatibility: The Kastar batteries are compatible with Canon LP-E6 series battery mounts and work in cameras such as Blackmagic Pocket Cinema Camera 4K and 6K and the Z CAM E2C.

Who It's For

This kit is best for indie filmmakers, run-and-gun shooters, and hybrid photo/video operators who need extra runtime without carrying camera-specific wall chargers. The USB input makes it particularly useful for travel and fieldwork where a single 5V power source can keep multiple batteries topped up.

It is less suitable for users who require fastest possible charge times from a native high-voltage charger or those who need OEM-branded batteries for warranty reasons; professionals needing manufacturer support for high-intensity studio workflows may prefer original manufacturer batteries and chargers.

Pros & Cons

Pros

• Provides four spare LP-E6 style batteries so shooting time is extended without frequent swaps.
• Dual-bay USB charger supports charging two batteries at once from either Micro-USB or Type-C power sources.
• LED indicators and interchangeable plates add practical convenience for multi-camera kits and quick checks on battery status.

Cons

• Charging via 5V USB is convenient but not as fast as some dedicated high-voltage camera chargers.
