FirstPower 360 X4 Battery 2-Pack with Triple Slot Charger - Extended

In this review the FirstPower 360 X4 Battery 2-Pack with Triple Slot Charger is judged on whether it solves the most common limitation of action camera shooting: limited runtime. For users of the Insta360 X4 who need longer shoots or quick on-the-go charging, this kit delivers with two high-capacity 2500mAh batteries and a compact charger that doubles as storage. The reviewer found it reliable for extended sessions and especially useful when paired with a USB-C power bank for charging on location.

Key Features

• Perfect Fit: Designed specifically for the Insta360 X4, the batteries sit snugly and allow normal camera operation without interference.
• Extended Power: Each 2500mAh battery provides more runtime than typical stock cells, helping capture longer clips without a memory effect.
• Triple Charging: The charger can charge up to three batteries at once from a USB-C input, which speeds turnaround between shoots.
• Smart LED Display: Independent LED indicators show charging progress so you can tell at a glance which cells are charging or fully charged.
• Safety First: Built-in protections guard against overcharge, short circuits, high temperature and overvoltage for safer field use.
• Portable Design: The charger doubles as a storage box and the kit includes two battery cases, making it convenient for travel and transport.

Who It's For

The kit is best for Insta360 X4 owners who shoot long sessions, travel often, or work in situations where access to mains charging is limited; the two 2500mAh cells and triple-slot charger reduce downtime between takes. It also suits casual creators who want a compact charging solution that doubles as a protective case.

Photographers who require waterproof batteries for direct underwater use should look elsewhere or use a dedicated waterproof housing, since the batteries themselves are not waterproof. Users needing OEM-branded cells or specific manufacturer warranty terms may prefer original batteries from the camera maker.
