Kastar 2-Pack NP-F750 NP-F770 Battery and LTD2 USB Charger - Dual

In this review the Kastar 2-Pack NP-F750 / NP-F770 Battery and LTD2 USB Charger is evaluated for camera operators and field monitor users who need reliable, long runtime power without juggling multiple chargers. The bottom line: this combo delivers high-capacity 5800mAh lithium-ion power and a compact, flexible USB charger that can top two batteries at once, making it a sensible choice for users of Lilliput A7S, H7 and similar field monitors. It is a practical, affordable replacement battery set designed for continuous on-set use and long shoot days.

Key Features

• High capacity battery: Each 5800mAh lithium-ion cell gives extended runtime for monitors and cameras so you can shoot longer between swaps.
• Dual battery pack: The 2-pack provides a spare on hand, reducing downtime while one battery charges and the other powers gear.
• USB dual charger: The LTD2 USB charger charges two batteries at once and shows the status with intelligent LED indicators for easy monitoring.
• Multiple input options: The charger accepts Micro-USB and Type-C input and includes a Micro USB cable, allowing use with common power banks and phone adapters.
• Interchangeable plate: The charger can change the plate to accept different battery types, adding flexibility for users with mixed battery inventories.
• Portable power draw: The charger runs from a 5V 2-3A input and delivers 8.4V 800mA outputs so it is convenient to run from USB sources on-location.

Who It's For

The Kastar 2-Pack is well suited to videographers and photographers who use Lilliput A7S 7in and similar field monitors and need dependable spare power on location. It is particularly helpful for run-and-gun shooters, small crews and solo operators who prefer compact, USB-chargeable solutions that reduce the need for bulky AC chargers.

Those who should look elsewhere include users who require manufacturer-branded batteries for warranty or compatibility assurance with proprietary systems, and professionals needing rapid high-current charging beyond the 800mA per bay rate. If you need studio-scale charging speed or an integrated V-mount system, consider higher-capacity or dedicated chargers.

Pros & Cons

Cons
