Kastar 4-Pack Battery and LKD2 USB Charger Compatible with Blackmagic

Our review of the Kastar 4-Pack Battery and LKD2 USB Charger finds it best for shooters who need dependable spare power for a Blackmagic Design Pocket Cinema Camera 6K Pro. The single biggest reason to buy is the combination of four 2900mAh lithium-ion packs plus an intelligent dual-slot charger that displays status on an LCD, making back-to-back shoots easier to manage. This kit focuses on extended runtime and portability rather than cutting-edge fast charging, and it delivers predictable, camera-compatible voltage for uninterrupted recording sessions.

Key Features

• High capacity batteries: Each 2900mAh lithium-ion cell gives noticeably longer runtime for long takes or extended field shoots.
• Camera compatibility: Packs are built to work with the Blackmagic Design Pocket Cinema Camera 6K Pro and other compatible models, avoiding V-mount or plate adapters.
• Dual-slot LCD charger: The Kastar LKD2 charger displays charging status and battery capacity so users can monitor two batteries at once without guesswork.
• Multiple input options: Charger accepts Micro-USB and Type-C inputs and includes a Micro USB cable for flexible mobile or desktop charging.
• Portable power solution: The compact charger and four-battery bundle are easy to carry for location shoots and quick battery swaps.

Who It's For

This kit is aimed at independent filmmakers, run-and-gun videographers and camera operators using the Blackmagic Pocket Cinema Camera 6K Pro who require several ready-to-use batteries and a small dual charger. The 2900mAh cells are practical for full-day shoots when paired with intermittent charging from a USB power bank or mains adapter.

Those who should look elsewhere include users wanting the fastest possible recharge times or power delivery to peripherals; the charger outputs 8.4V at 650mA per slot so it is not designed as a rapid charger for heavy-duty, same-day turnaround in high-volume rental houses.

Pros & Cons

Pros

• Four batteries provide redundancy so swaps are quick and uninterrupted.
• Intelligent LCD charger shows individual battery capacity and charge status.
• Micro-USB and Type-C input options add flexibility for charging from common adapters or power banks.

Cons

• Charger output of 650mA per slot means slower charging compared with specialized fast chargers.
