Kastar 4-Pack NP-FP70/FP71 Battery and LTD2 USB Charger - Reliable

In this review the Kastar 4-Pack NP-FP70/FP71 Battery kit is examined for camcorder users who need dependable spare power and a flexible charging solution. The bottom line: this kit is for photographers and videographers using Sony-compatible batteries who want a compact, dual-bay USB charger and extra capacity on hand. The single biggest reason to buy is the combination of high capacity 2400mAh Lithium-Ion cells and a charger that accepts both Micro-USB and Type-C inputs, making it easy to top up two batteries simultaneously when on location.

Key Features

• Battery Capacity: Each 2400mAh cell offers extended runtime so users can shoot longer sessions between swaps.
• Voltage: The 7.4V Lithium-Ion design is compatible with the NP-FP70/FP71 form factor used in many Sony camcorders for reliable performance.
• Dual Charging: The LTD2 USB dual charger can charge two batteries at once, reducing downtime when multiple batteries are in rotation.
• USB Convenience: Micro-USB and Type-C input options and a Micro USB cable included let you charge from power banks, laptop ports, or USB wall adapters.
• Smart LED Display: Intelligent LED indicators show charging status and relative battery capacity, helping avoid guesswork on remaining charge.
• Interchangeable Plate: The charger plate can be changed to accept different compatible battery plates, adding versatility for mixed battery kits.

Who It's For

This kit is aimed at users of legacy Sony DCR and similar camcorders who need multiple spare batteries and a compact charging solution for fieldwork, event shooting, or travel. Wedding videographers, documentary shooters, and families recording long events will appreciate the higher 2400mAh capacity and dual charging to keep two batteries ready.

Photographers who need the absolute fastest charging speeds or OEM branded batteries for manufacturer warranty reasons should consider other options; likewise, users who do not need multiple spare batteries may find a single higher-power solution more appropriate.

Pros & Cons

Pros

• High 2400mAh capacity extends shooting time compared with smaller replacement cells.
• Dual-bay charger allows charging two batteries simultaneously, saving time between shoots.
• USB input flexibility (Micro-USB and Type-C) makes charging convenient in varied locations.
• Included Micro USB cable and LED indicators simplify everyday use and monitoring.

Cons

• Charge output is capped at 8.4V 800mA per bay, so charging two batteries at once is not the fastest option available.
• Compatibility is focused on NP-FP series batteries, so it is not a universal solution for all battery types.
