DJI Osmo Action Multifunctional Battery Case - Fast Charging, Storage

In this review of the DJI Osmo Action Multifunctional Battery Case the bottom line is simple: this accessory is for Osmo Action 3 and 4 users who need neat, portable battery storage and rapid on-the-go charging. The case stores three compatible Osmo Action Extreme batteries plus two microSD cards, and it can fast charge those batteries internally while also acting as a power bank for a smartphone or other device. The build and pocket-friendly dimensions make it a practical carry solution for multi-battery shooters who prioritize convenience and quick top-ups.

Key Features

• Triple battery storage: Holds three Osmo Action Extreme batteries so you can carry spare power without loose cells cluttering your bag.
• Dual microSD slots: Two microSD card bays keep extra media organized and protected for long shoots or travel projects.
• Fast internal charging: The case intelligently fast charges three batteries, reducing downtime between sessions.
• Power bank function: When paired with installed batteries the case can be used to charge external devices like a smartphone.
• Compact footprint: At roughly 116 x 25.9 x 22.29 mm it slips into pockets easily for transport.
• Clear compatibility note: Works only with the Osmo Action Extreme Battery, which avoids accidental use with incompatible battery models.

Who It's For

The case is ideal for Osmo Action 3 and Osmo Action 4 owners who routinely use multiple batteries during a day of shooting and want a single tidy solution for storage, charging, and emergency power. Adventure shooters, vloggers and sports camera users who need rugged, pocketable kit will appreciate the combination of storage and fast charging.

It is less suitable for users who own the Osmo Action Extreme Battery Plus (1950 mAh), since that battery is not compatible, or for buyers expecting an included charging cable in the box. Budget shoppers who find the accessory overpriced may prefer third-party storage options without the charging feature.

Pros & Cons
