Kastar NP-F750 NP-F770 3-Pack Battery with LTD2 USB Charger - Reliable

In this review the Kastar 3-Pack NP-F750 / NP-F770 Battery kit is evaluated for on-camera and studio photographers and videographers who need long runtime and flexible charging. The bottom line: this pack is aimed at creators using compatible LED panels such as Neewer NL-288ARC or Bi-Color 660 lights and delivers high capacity 5800mAh lithium-ion cells that noticeably extend run time compared with typical camera batteries. The included LTD2 USB charger adds convenience with simultaneous two-bay charging, multi-input options, and a clear LED charge status to keep a small kit running without a bulky charging station.

Key Features

• High capacity cells: Each 5800mAh lithium-ion battery provides extended run time for continuous shooting or long video sessions.
• Dual-bay charging: The LTD2 charger can charge two batteries at the same time so you can top up multiple spares between shoots.
• Flexible power input: Charger accepts Micro-USB or Type-C input and runs on a 5V 2-3A supply, making it usable with common power banks and USB adapters.
• Interchangeable plate design: The charger can change the plate to fit different battery plate types, which adds versatility for users with varied gear.
• Intelligent LED display: The USB charger shows charging status and battery capacity with LED indicators so you can see progress at a glance.
• Portable charger output: The charger provides 8.4V at 800mA per bay and is small and easy to carry for on-location work.

Who It's For

The Kastar pack is best for photographers and videographers who use compatible LED video lights such as NL-288ARC, Professional Dimmable Bi-Color 660, SNL660, Advanced 660, or P200 CRI97+ fixtures and want higher-capacity spares that keep lights running longer between swaps. It suits content creators who travel light and prefer USB-powered accessories that can be charged from laptop chargers, USB-C adapters, or power banks.

Those who should look elsewhere include users requiring proprietary fast charging protocols beyond 8.4V 800mA per bay or productions that need hot-swap, in-rig battery mounting with manufacturer warranties tied to OEM cells. This kit focuses on capacity and convenience rather than ultra-rapid charging.
