In this review the Kastar 2-Pack NP-F750 / NP-F770 Battery and LTD2 USB Charger is evaluated for photographers and videographers who need reliable runtime and flexible charging for LED video lights. The bottom line: this kit is for users who want high-capacity 5800mAh camera batteries and a compact dual charger that can power two batteries at once or accept multiple input types. The review covers real-world battery capacity, charger behavior, and who will benefit most from buying this battery and charger bundle.

Key Features

• High capacity battery: The 5800mAh lithium-ion cells offer extended runtime for LED video lights, reducing the need to swap batteries during a shoot.
• Dual battery charging: The LTD2 charger can charge two batteries simultaneously, which is convenient for keeping a set fully ready between takes.
• Flexible input options: The charger supports Micro-USB and Type-C input and ships with a Micro USB cable for charging from power banks or USB adapters.
• Smart LED indicators: Intelligent LED display shows charging status and estimated remaining battery capacity to plan runtime and swaps.
• Interchangeable plates: The charger accepts changeable plates to charge different battery plates, making it adaptable to similar battery formats.

Who It's For

The Kastar kit is best for content creators, independent videographers, and photographers using compatible LED video lights who need a portable, higher-capacity battery solution to extend shooting time. It suits anyone who values being able to recharge two batteries at once and wants clear LED feedback on charge status.

It is less suitable for those who require manufacturer-branded batteries for warranty reasons or people who need extremely fast professional chargers with higher amperage than the LTD2 provides. Also, users who do not use NP-F750/NP-F770 style batteries should look for a kit matched to their battery plate.

Pros & Cons

Pros

• 5800mAh capacity provides noticeable extra runtime compared with lower-capacity alternatives.
• LTD2 charger charges two batteries simultaneously, streamlining gear preparation for shoots.
• USB input options and included Micro USB cable make it easy to charge from common USB power sources.

Cons

• The charger output is limited to 800mA per bay, so charging is not as fast as higher-current professional chargers.
