TQTHL Osmo Action 5 Pro / 4 / 3 Battery Charger Kit (2 x 2800mAh) for Osmo Action Cameras

What this is and what it solves

This is a 2-pack battery charger kit with two 2800mAh replacement batteries and a two-channel LED charger designed for Osmo Action 5 Pro, Osmo Action 4 and Osmo Action 3 cameras. It provides spare power and a dedicated charging setup, so you’re less likely to miss a shoot due to a flat battery. On the paper, the kit aims to offer a practical, all-in-one solution for ongoing filming sessions where extended runtimes matter.

Battery and charging basics

Each battery is specified as 34.6×44.5×11.4 mm with a nominal voltage of 3.87 V and a maximum charging voltage of 4.45 V, rated at 2800 mAh. The charging block supports simultaneous charging of both batteries, with an LED indicator showing the status of each cell. The included charging case with lid adds an extra layer of protection when you’re travelling or swapping packs between shoots.

Compatibility and cautions

The batteries are described as fully compatible with Osmo Action 5 Pro, Osmo Action 4 and Osmo Action 3 cameras. However, it’s important to note that they are not stated as compatible with Osmo Action/Osmo Action 2. Before purchase, check your device model to avoid mismatches. The kit can be charged via a power outlet or mobile power bank, but the charger must output 5V/3A. Using other charging sources (like a car charger) isn’t recommended unless the current and voltage align with 5V/3A.

What’s included and build quality cues

In the box you’ll find 2 × Osmo Action 5 Pro batteries (2800mAh), 1 × LED charging dock, and 1 × USB Type-C cable. The charger case with a lid is designed to protect the unit in transit. The kit’s build appears straightforward: you plug in the USB-C, drop the batteries in, and monitor the LED indicators. The documentation mentions a 12-month warranty and responsive support, which helps in case you run into issues.

Pros and what stands out in use

• Two batteries in one package reduce downtime between shoots, which is handy for event days or longer filming runs.
• The dual-channel charger shows charging status per cell, so you can manage two packs at once without guesswork.
• The included lid-protected charging case adds portability and some protection against dust or minor knocks.
• The kit is compact enough to travel with a camera bag without adding much bulk.

Limitations and where it may fall short

• The stated compatibility excludes Osmo Action 2, so if you own that model or are considering a broader Osmo ecosystem, these cells may not work.
• The guidance to use only 5V/3A chargers limits flexibility a bit, a car charger isn’t recommended unless it meets that spec, which could be inconvenient in some scenarios.
• No information is given on cycle life, discharge rates, or how long each battery lasts in continuous recording, so real-world endurance may vary.

Who this is most suited for

• Owners of Osmo Action 5 Pro, 4 or 3 cameras who need reliable back-up power for longer shoots or travel days.
• Filmmakers or vloggers who value keeping two charged batteries ready without hunting for spare cells between sessions.
• Travellers who want a compact, self-contained charging solution with protection features.

Who might want to look elsewhere

• If you own Osmo Action 2 or expect broad compatibility across older or newer models, these batteries may not be the best fit.
• If you require detailed technical guarantees about cycle life or performance under extreme temperatures, the provided information doesn’t cover those specifics.

When does it make sense to buy

• You regularly shoot with Osmo Action 5 Pro, 4 or 3 and want a ready-to-go two-pack plus a dedicated charger.
• You value the convenience of charging two batteries simultaneously with a clear LED status and a portable protective case.

What to check before buying

• Confirm your camera model (avoid Osmo Action 2 or other models not listed).
• Ensure you have a 5V/3A charging source for optimal charging.
• Consider how often you’ll need spare power and whether you prefer an integrated charging case.

Practical usage example

Imagine a day of documentary shooting. You swap in a freshly charged 2800mAh battery, capture a sequence, and switch to the second battery while the first charges in the dock. The LED indicators give you a quick read on which pack is ready. Once back in the hotel, you can recharge both batteries and re-pack them for the next day’s shooting without hunting for loose cells.

FAQ (based on available data)

• Are these batteries compatible with Osmo Action 2? Not according to the specified compatibility.
• Can I charge both batteries at the same time? Yes, the charger supports two-channel charging.
• Do I need a special car charger? Not really, use a 5V/3A charger as advised.

Is it worth it?

It makes sense if you prioritise uninterrupted filming with your Osmo Action 5 Pro/4/3 and want a compact, two-pack solution with a protective charger case. If your usage is light or you rarely rely on back-up power, you might not need the extra packs.
