Kastar 4x Battery and LTD2 USB Charger Replacement for Fujifilm NP-80

Our review of the Kastar 4x Battery and LTD2 USB Charger finds it ideal for photographers who need reliable spare power for legacy Fujifilm and related cameras. The bottom line: this kit pairs four 3.7V 2100mAh Lithium-Ion cells with a compact dual USB charger that can top up two batteries at once, making it a sensible choice for travel and extended shoots where original replacements are scarce. The included Micro-USB cable and two input options make it convenient to power from modern USB power banks or wall adapters.

Key Features

• Battery Capacity: Each 2100mAh cell provides extended runtime so users can shoot longer between battery swaps.
• Dual Charging: The LTD2 USB charger can charge two batteries simultaneously, cutting downtime when multiple spares are in use.
• Interchangeable Plate: The charger plate can be changed to accommodate different battery contacts, increasing compatibility with similar models.
• Multiple Inputs: With Micro-USB and Type-C input options and a Micro USB cable included, it is easy to charge from a power bank or modern USB adapter.
• Smart LED Display: Intelligent LED indicators show charging status and relative battery capacity so users can monitor progress at a glance.
• Portable Design: The compact charger and spare batteries are easy to carry for travel or long shoots without access to mains power.

Who It's For

This kit suits owners of older Fujifilm FinePix models and compatible cameras who need authentic-feeling replacements without paying premium prices for discontinued OEM parts. Enthusiasts who travel, cover events, or shoot extended sessions will appreciate having four spare NP-80-compatible batteries and a charger that accepts USB power sources.

Photographers who require manufacturer warranty support or the absolute smallest, lightest batteries should consider the original branded batteries or a different form factor; this kit is focused on compatibility and convenience rather than being the lightest possible option.
