Kastar NP-F990 Battery 4-Pack and LTD2 USB Charger - High Capacity

In this review the Kastar NP-F990 Battery 4-Pack and LTD2 USB Charger is assessed for users who need long runtime and flexible charging for legacy Sony-style camcorders and LEDs. The bottom line: this kit is for video shooters and power-hungry camera operators who want a high-capacity, portable power solution without juggling single small cells. The review highlights the 11600mAh Lithium-Ion batteries and the dual-slot USB charger with both Micro-USB and Type-C inputs as the main reason to consider this pack.

Key Features

• High capacity: Each 11600mAh lithium-ion battery provides extended run time so cameras and monitors stay powered through long shoots.
• Wide compatibility: Works with a broad range of Sony NP-F series batteries and many older camcorder models, offering a simple replacement for NP-F750/770/930/950/960/970/980/990 formats.
• Dual charging: The LTD2 charger can charge two batteries simultaneously, saving time between takes and reducing downtime on location.
• Multiple input options: Charger accepts Micro-USB and Type-C input, so it can be powered from common USB power banks or modern wall adapters.
• Smart LED indicators: Built-in LED displays show charging status and relative battery capacity, making it easy to check progress at a glance.
• Portable design: The charger is compact with a 5V 2-3A input and 8.4V 800mA outputs, making it easy to carry in a camera bag and use with 15W USB supplies.

Who It's For

This kit is aimed at content creators, event videographers, and anyone using cameras or accessories that accept Sony NP-F style batteries and need long single-charge runtimes or multiple spare cells. The 11600mAh capacity is especially useful for full-day shoots, continuous LED lighting, or monitor use.

It is less well suited for users who require official brand batteries with manufacturer warranties or for devices that need OEM charging protocols. If you only need a single backup battery or prefer fast high-current charging from a proprietary dock, other options could be better.

Pros & Cons

Pros

• High 11600mAh capacity provides long runtime for cameras and accessories.
