Kastar 1-Pack Battery and LTD2 USB Charger - High Capacity 8850mAh

In this review the Kastar 1-Pack Battery and LTD2 USB Charger is evaluated for camera operators who use compatible Panasonic camcorders and need a reliable spare power solution. The bottom line: this kit pairs a high-capacity 8850mAh lithium-ion battery with a dual-mode USB charger that is useful for extended shoots and back-to-back battery swaps. It is best for field shooters, ENG crews, and videographers who want long runtime and flexible charging via Micro-USB or Type-C inputs without carrying multiple bulky chargers.

Key Features

• High capacity battery: The 8850mAh, 7.4V lithium-ion pack provides extended runtime so users spend less time changing batteries on long shoots.
• Dual charging slots: The LTD2 charger can charge two batteries simultaneously for faster turnaround when multiple spares are in use.
• Interchangeable charging plate: The charger offers a changeable plate so it can accept different compatible battery shapes, increasing compatibility with Panasonic models listed.
• Smart LED display: The charger uses an intelligent LED indicator to show charging status and approximate battery capacity so operators can tell when a pack is ready.
• Multiple input options: Micro-USB and Type-C input options and a supplied Micro-USB cable allow charging from power banks, USB adapters, or in-vehicle chargers for on-location flexibility.
• Compact, portable supply: The charger accepts 5V 2-3A input and delivers 8.4V outputs, keeping size and weight down for easier transport in a camera bag.

Who It's For

This kit is aimed at professional and prosumer videographers who use Panasonic camcorders such as the AG-DVX200 series, AJ-PX models, HC-X1 and similar cameras that accept the listed battery types. It suits anyone needing long runtime from a single pack plus the convenience of charging two batteries when time is limited.

It is less suitable for users who require manufacturer service support or warranty coverage tied to original-brand batteries, or for those who only need a single lightweight replacement for occasional casual use.

Pros & Cons

Pros

• Large 8850mAh capacity gives noticeably longer run times compared with typical stock packs.
• Dual-slot charger with simultaneous outputs helps keep multiple spares ready between shoots.
• USB input options and supplied Micro-USB cable make on-location charging convenient from power banks or USB adapters.
• LED indicators provide clear visual feedback on charge status and approximate capacity.

Cons

• Charger input is limited to 5V 2-3A so charging speed depends on the USB power source used.
• Not an original Panasonic-branded pack, which may concern users who prefer OEM batteries.
