Kastar 2-Pack NP-F750 NP-F770 Battery with AC Wall Charger - Reliable

In this review of the Kastar 2-Pack NP-F750 / NP-F770 Battery and AC Wall Charger replacement, the bottom line is simple: this kit is for videographers and camera operators who need extended runtime for on-camera field monitors without fuss. The reviewer found the most compelling reason to buy is the combination of two high-capacity 5800mAh lithium-ion batteries and a compact AC charger with a foldable flat pin, which together deliver convenient, portable power for a full day on set or in the field. This package replaces depleted NP-F750/NP-F770 cells and keeps monitors running reliably between shoots.

Key Features

• High-capacity cells: The 5800mAh lithium-ion batteries provide significantly longer runtime than standard cells, reducing the need to swap batteries during long shoots.
• Wide charger input: The AC charger accepts AC 100~240V 50~60Hz, so it will charge from international mains voltages without a separate transformer.
• Clear charge indicator: An LED shows red while charging and green when the battery is on standby or fully charged, making it easy to confirm status at a glance.
• Compact charger design: The charger features a foldable flat pin for easy storage and transport, useful for cramped kit bags.
• Ready kit: Package includes two batteries and one AC charger, which covers most single-monitor use cases and light multi-device setups.

Who It's For

This kit is aimed at content creators who use on-camera field monitors such as Neewer F100/F200 and a range of 5in to 7in monitors from brands like Blackmagic, SmallHD, and Portkeys, and who need dependable, higher-capacity replacements for NP-F750 / NP-F770 style batteries. It is particularly useful for run-and-gun shooters, solo operators, and small production teams that want to minimize downtime.

Those who should look elsewhere include users who require vehicle charging accessories or international plug sets out of the box, since the package does not include a car adapter or European plug. Also, if you need more than two batteries or faster charging speeds, consider a larger multi-bay charger or additional battery packs.

Pros & Cons

Pros

• High 5800mAh capacity gives noticeably longer monitor runtime compared with lower-capacity alternatives.
• Charger accepts 100~240V input so it can be used on varied mains voltages while traveling.
• LED charge indicator and foldable flat pin on the charger make daily use clear and compact.

Cons

• Package lacks a car adapter or alternate plug heads, so extra accessories may be needed for some workflows.
• Charger output is DC 8.4V 600mA, which is adequate but not a high-speed charger for rapid top-ups.
