Kastar 4-Pack Battery and LTD2 USB Charger - Compact Dual Charge

Our review of the Kastar 4-Pack Battery and LTD2 USB Charger finds it is aimed at Gopro Fusion owners who need reliable spare power and a flexible charging setup. The biggest reason to consider this pack is convenience: it combines four 2720mAh lithium-ion batteries with a dual-bay charger that accepts both Micro-USB and Type-C input, so shooters can keep multiple batteries topped up from a single 5V USB source. For day trips, VR capture sessions, or travel where wall outlets are limited, the set offers useful capacity and clear charging feedback via intelligent LEDs.

Key Features

• High capacity batteries: Each 2720mAh lithium-ion cell provides extended runtime for Fusion 360-degree sessions so users can shoot longer between swaps.
• Dual-bay charging: The LTD2 charger can charge two batteries at the same time, which reduces downtime when preparing for long shoots.
• Swappable plate design: The charger plate can be changed to fit different battery configurations, adding versatility for mixed workflows.
• Dual input options: With both Micro-USB and Type-C input and a supplied Micro-USB cable, the charger adapts to common power sources while supporting up to 5V 2-3A input.
• Visible charge status: Intelligent LED indicators show charging progress and battery capacity so users know when packs are ready to go.

Who It's For

This kit is best for owners of the Gopro Fusion 360-Degree Action Camera or Fusion VR 360 Camera who shoot multi-battery sessions and want a compact way to store and charge spares. Content creators who travel, capture long events, or record time-lapse sequences will appreciate the higher capacity cells and the ability to charge two batteries at once.

Photographers or videographers who need ultra-fast professional charging or an integrated AC-powered dock may want to look elsewhere; the charger is USB-powered with 4.2V 800mA outputs per bay and is designed for convenience rather than the fastest possible recharge times.
