Osmo Action 5 Pro/4/3 Battery Charger Kit 3-Pack - Fast 3-Channel Hub

In this review the DFTIM Osmo Action 5 Pro/4/3 Battery Charger Kit earns a recommendation for shooters who need reliable spare power and a compact charging solution. The bundle includes three 2100mAh Li-ion batteries rated at 3.87V and a 3-channel fast charger hub that can top two batteries simultaneously while showing charge status with LEDs. For users who record for extended periods or travel with limited outlets, the kit's multiple charging options and built-in safety protections are the single biggest reason to buy.

Key Features

• High capacity battery: Each 2100mAh Li-ion battery provides roughly 60 minutes of runtime per charge, helping you shoot longer without swapping too often.
• 3-channel fast charger: The charger hub supports charging up to two batteries at once and provides a third channel for staggered charging to keep spares ready.
• LED charge indicators: Dedicated red and green LEDs show charging progress so you can quickly see when a battery is fully charged.
• Dual input options: The charger accepts a built-in USB-A cable or a USB-C input, letting you power it from a wall adapter, car charger, or power bank.
• Smart safety protections: Each battery includes a built-in smart chip with over-charge, over-discharge, over-voltage, over-current, and over-heating protection to reduce risk during charging and use.

Who It's For

The kit is best for action camera shooters using DJI Osmo Action 3, Action 4, or Action 5 Pro who need multiple hot-swappable batteries and a compact charger to keep recording during long outings or multi-hour shoots. The combination of three spare batteries and a 3-channel hub fits well for travel vloggers, adventure athletes, or event videographers who cannot rely on a single battery.

Photographers who demand factory-original batteries for maximum compatibility with every firmware update or those who require the exact original voltage for an Action 5 Pro may prefer official batteries instead, since replacement Action 4 cells used in Action 5 devices can differ in voltage from the original Action 5 battery.

Pros & Cons

Pros

• Three 2100mAh batteries give substantial extra runtime and simplify long shooting sessions.
• 3-channel charger with LED status lights makes it easy to manage multiple batteries at once.
• USB-A and USB-C charging inputs add flexibility for charging from a variety of power sources.
• Built-in safety chip provides multiple protections to help prolong battery life and reduce risk.

Cons

• Replacement Action 4 batteries used in Action 5 devices may have different volts than original Action 5 batteries, so check compatibility for some models.
