Kastar Battery and Smart USB Charger Pack for Sony NP Series

In this review the Kastar 1-Pack Battery and Smart USB Charger is presented for owners of older Sony camcorders that use NP-series Ni-MH packs. The bottom line: this kit is for users who need a straightforward replacement battery with a smart, portable charger that supports both Micro-USB and Type-C input and shows charge status with an LED. It replaces Sony NP-33/55/66/77/98 series packs with a 6.0V, 4800mAh Ni-MH cell and includes a smart charger that accepts 5V 2-3A input for flexible charging on the go.

Key Features

• High capacity battery: The 4800mAh Ni-MH battery supplies extended run time so recording sessions last longer between charges.
• Exact voltage match: The 6.0V output matches the original NP-series requirements for compatible Sony camcorders to ensure reliable operation.
• Smart USB charger: The included charger provides a regulated 6.0V 800mA output and displays charging status and battery capacity via an intelligent LED indicator.
• Multiple input options: The charger accepts Micro-USB and Type-C inputs and comes with a Micro USB cable, making it convenient to power from common USB adapters or power banks.
• Portable kit: The one-battery, one-charger package is compact and easy to carry for field use or travel, replacing bulky original chargers.

Who It's For

The Kastar pack is best for owners of legacy Sony CCD and CCD-F series camcorders that list compatibility with NP-33, NP-55, NP-66, NP-77, NP-98 and related battery codes; it is a practical choice when the original battery no longer holds a charge. It also suits photographers and videographers who need a simple, portable charging solution that can be powered from USB sources while working on location.

Users who require manufacturer service-level warranties, proprietary fast-charging systems, or OEM-branded accessories should look elsewhere; this third-party pack focuses on compatibility, capacity and portability rather than matching every OEM accessory feature.

Pros & Cons

Pros

• High 4800mAh Ni-MH capacity provides noticeably longer runtime than many older packs.
• Smart charger with LED status makes it easy to see charging progress and estimated capacity.
• USB input options and included Micro USB cable add convenience for travel and field charging.

Cons

• Charger output is 800mA so charging takes a moderate amount of time compared with high-current proprietary chargers.

Specifications

Our Verdict

The Kastar battery and smart USB charger pack is a sensible replacement for older Sony NP-series camcorders, offering solid 4800mAh capacity and a compact, USB-powered charger with LED status. It delivers good value for users who need reliable runtime and flexible charging options, though the 800mA charger output means a full recharge is not fast. For most hobbyists and field shooters with compatible Sony models, this kit is a practical and cost-effective power solution.

Frequently Asked Questions

Will this battery work in my older Sony camcorder?
Check your camera manual or battery compartment label for compatibility with NP-33, NP-55, NP-66, NP-77, NP-98 or related NP-series codes; this pack targets those models.

Can I charge the battery from a power bank?
Yes, the smart charger accepts 5V USB input and supports Micro-USB or Type-C, so a power bank with sufficient output can be used to charge it in the field.

How long does a full charge take?
Because the charger provides a 6.0V 800mA output, expect a moderate charge time; exact duration depends on battery state and input current but it is not a rapid charge.
