Battery Charger for DJI Osmo Action Series - Triple Slot 27W Fast Hub

In this review of the naivvy Battery Charger for DJI Osmo Action series, the bottom line is clear: it is for shooters who need fast, portable multi-battery management and occasional power for a phone. The charger acts as a 5-in-1 solution that combines a 27W dual-channel fast charger, 10W power bank output, battery storage and balancing functions, and a smart display in one compact case. For action camera users who travel or shoot extended sessions, the main reason to buy is the convenience of charging multiple Osmo Action and Osmo 360 batteries quickly while monitoring charge status on a crisp OLED screen.

Key Features

• Fast dual-channel charging: The 27W dual-channel system charges two batteries simultaneously to reduce downtime between shoots.
• 10W power bank output: The charger can discharge to power a phone or accessory when mains power is unavailable.
• Battery storage and equalizer: The device stores up to three batteries and evens out charge levels to protect battery health during long trips.
• Smart OLED display: The 1.47' OLED shows battery state of charge, voltage, current and available power so users can check status at a glance.
• Bidirectional design: It charges batteries and can reverse as a power source, which adds flexibility on location shoots.
• Accurate charging management: TI charging chips with per-channel calibration reduce the risk of overcharge or undercharge compared with typical chargers.

Who It's For

This charger is aimed at DJI Osmo 360 and Osmo Action 3/4/5 Pro users who frequently swap batteries and need a compact hub that combines fast charging with monitoring and power bank capabilities. Travel vloggers, outdoor filmmakers and hobbyists who carry multiple spare batteries will appreciate the space-saving case and the OLED feedback.

It is less relevant for users who only occasionally use their action camera and already have a manufacturer charger, or for those who require extremely high-capacity power bank features beyond the 10W output. Professional rigs that demand studio-level charging fleets may prefer dedicated multi-bay masters instead.

Pros & Cons

Pros

• Charges two batteries quickly with a combined 27W output to minimize downtime.
• Works as a 10W power bank to charge phones or accessories in the field.
• OLED display provides clear, real-time battery and power information.
• Includes battery equalizing and storage features to maintain battery health during travel.

Cons

• Not a replacement for high-capacity power stations if extended charging of many devices is required.
• Designed specifically for DJI Osmo Action and Osmo 360 series batteries, so compatibility outside that range is limited.
