Kastar NP-F990 Battery 3-Pack with LTD2 Dual USB Charger - Long Run

In this review the reviewer tested the Kastar NP-F990 Battery 3-Pack with the LTD2 dual USB charger to see if it solves the common problem of running out of power during long shoots. The bottom line is that this kit is aimed at camera users who need high-capacity, swappable power and a flexible charger option; the standout reason to buy is the large 11600mAh lithium-ion battery capacity that extends runtime far beyond standard cells. The package also includes a dual charger with interchangeable plates and both Micro-USB and Type-C input options that make charging on the go practical.

Key Features

• High capacity: Each 7.2V, 11600mAh battery provides extended runtime for long recording sessions or field work, reducing the need to swap batteries frequently.
• Dual charging: The LTD2 charger can charge two batteries simultaneously, which is useful for keeping multiple spares ready during back-to-back shoots.
• Interchangeable plates: The charger accepts changeable plates so it can accommodate several NP-F series models, making it versatile for owners of different camera gear.
• Multiple inputs: Micro-USB and Type-C inputs plus a supplied Micro USB cable give flexible power options from power banks or adapters when AC is not available.
• Smart LED display: An intelligent LED display shows charging status and gives a quick visual cue of battery capacity so users know when a cell is ready.
• Portable charger: The charger operates from a 5V 2-3A input and delivers 8.4V at 800mA per channel, keeping the unit compact and easy to carry.

Who It's For

This kit is best for videographers, independent filmmakers, and photographers who use cameras compatible with NP-F series batteries and need long run times without frequent battery swaps. The large 11600mAh cells suit location shoots, event coverage, and anyone who prefers carrying a few high-capacity spares instead of many smaller batteries.

It is less appropriate for users who only need a single lightweight battery for occasional use, or for those who require manufacturer-branded cells with proprietary charging ecosystems. Also, if you need ultra-fast charging beyond the chargers 800mA per channel output, a different fast-charge solution would be preferable.

Pros & Cons

Pros

• High 11600mAh capacity delivers long operating times and reduces downtime between swaps.
• Charger supports two batteries at once, helping maintain multiple ready batteries for continuous use.
• Interchangeable plates and USB input options make the charger versatile across NP-F variants and power sources.
• Smart LED indicators provide clear charging status and simple monitoring.

Cons

• The chargers per-channel output of 800mA is practical but not the fastest option for rapid replenishment of high-capacity cells.
• Bulky high-capacity batteries add weight compared with lower-capacity alternatives.
