Kastar 4-Pack Battery and LTD2 USB Charger Compatible with Fujifilm

In this review the reviewer looks at the Kastar 4-Pack Battery and LTD2 USB Charger as a compact power kit for older Fujifilm and JVC compact cameras. The bottom line is that this kit is aimed at photographers who need multiple spares and a flexible USB charger, and the single biggest reason to buy is the combination of four 2100mAh lithium-ion batteries plus a dual-slot charger with both Micro-USB and Type-C inputs for convenient recharging on the go. The reviewer found the kit useful for day trips and extended shoots where swapping batteries quickly matters.

Key Features

• Four 2100mAh batteries: Provides extended runtime for cameras that use Fujifilm NP-100 or JVC BN-V101 style cells so users can shoot longer without interruption.
• Dual-slot charger: Can charge two batteries at the same time, reducing downtime between shoots and keeping multiple spares ready.
• Flexible USB input: Accepts Micro-USB and Type-C input and includes a Micro-USB cable, so charging is possible from power banks, laptop ports, or USB wall adapters.
• Intelligent LED display: Shows charging status and battery capacity so the user can quickly see which batteries are ready to use.
• Interchangeable plate: The charger plate can be changed to fit different battery shapes, adding compatibility and convenience for mixed camera kits.

Who It's For

This kit is best for hobbyist photographers, travel shooters, and videographers using older Fujifilm DS and FinePix models or compatible JVC compact cameras who need several charged spares without carrying multiple chargers. The 2100mAh cells are helpful for long days when access to mains power is limited.

People who should look elsewhere include users of newer camera models with proprietary high-capacity packs or professionals who require manufacturer OEM batteries for warranty or peak performance guarantees. If you need extremely fast charging beyond 800mA per slot, a dedicated high-speed charger would be a better fit.

Pros & Cons

Pros

• Four included batteries reduce the need to hunt for spare cells during extended outings.
• Dual charging slots and the ability to charge two batteries at once speeds turnover between uses.
• USB input options and included cable make it convenient to top up batteries from common power sources.
• LED readout provides clear feedback on charge status and remaining capacity.

Cons

• Maximum per-slot output is 800mA, so charging speed is moderate rather than rapid for users expecting fast recharge cycles.
• Kit is intended for specific NP-100 / BN-V101 style batteries, so it is not universal for all camera models.
