SMALLRIG Osmo Pocket 4P/4/3 Battery Handle for DJI (5705)

Introduction

SmallRig’s Battery Handle for the Osmo Pocket 4P/4/3 is a purpose-built power grip with a 5000mAh capacity. On paper, it promises longer shoots and practical on-set charging alongside a direct audio path via wireless microphone without extra adapters. If you’re looking to extend run-time during day-long shoots or quick vlogging sessions, this grip may be worth weighing against your current power setup.

What it is and what problem it solves

This accessory plugs into the Osmo Pocket system to add significant on-device power and a more comfortable hold. The built-in 5000mAh battery translates to around 6.5 hours of combined use with the host device, and it can recharge the Pocket 3 about 1.36 times. Crucially, it also supports 20W fast charging and maintains a live USB-C port to power other gear such as a fill light or a phone while you record. For creators who value uninterrupted shooting or need a steadier grip for longer sessions, the extra power is tangible.

Design and usability in practice

The grip length is optimised for a more comfortable and secure hold than some original accessories, with a built-in 1/4" screw thread at the base for tripod or selfie stick attachment. In real-world use, you’ll likely notice the extra heft when you’re walking or hand-holding for extended periods. If you prioritise a compact footprint, this is a trade-off to consider.

Power, charging and heat management

On paper, the 5000mAh cell paired with EVE cells and four MOSFETs, offers smart temperature control and a host of protection features: over-charge, over-discharge, over-current, over-voltage, under-voltage, high temperature and short-circuit protection. In practice, that means the system is designed to stay within safe operating temperatures during longer shoots. It also supports simultaneous charging—so you can keep the handle charging while the camera uses power. The rear USB-C port expands versatility, letting you charge other accessories during recording.

Connectivity for audio

A notable benefit is the built-in wireless microphone direct connection: you can connect a wireless mic straight to the Osmo Pocket without an extra adapter, preserving audio quality and simplifying setup for vlogs and interviews. If you frequently pair mics with the Pocket, this is a practical plus that reduces fiddling with conversion adapters.

What’s good and what isn’t so compelling

What stands out: noticeably longer run-time, straightforward direct mic connection, and the convenience of charging both the grip and the camera at once. The 1/4" thread adds mounting flexibility for tripods and selfie sticks, which is handy for fixed or semi-fixed shot setups.

However, there are caveats. The extra weight and size may not suit every pocket or travel scenario, and the benefit hinges on you needing extended power. If your typical shoots are shorter or you already have a compact charging plan, it might feel like a luxury rather than a necessity. Also, while heat management is addressed on paper, prolonged use in high-temperature environments could still see performance vary depending on ambient conditions.

Who it’s for

This accessory is likely to appeal to content creators who do long-form video, travel vloggers, or interview-style shooters who rely on dependable power and clean audio integration. It’s a sensible upsell if you want to avoid swapping batteries and you value a more stable handheld experience with additional on-device charging options.

Who it isn’t ideal for

If you rarely shoot more than 60–90 minutes at a time or if you prioritise the lightest possible setup, this grip may feel excessive. It targets users who want extended battery life and integrated charging—features not strictly necessary for casual use.

Important checks before buying

• Confirm compatibility with your exact Osmo Pocket model (4P/4/3) to avoid misalignment with the 1/4" mount.
• Consider your charging setup: a USB-C charger rated at 20W or higher is recommended for optimal performance.
• Factor in the additional weight and how it will affect handling during longer shoots.
• If you rely heavily on external accessories, the rear USB-C port’s usability for simultaneous charges could simplify your on-set workflow.

Comparison at a glance

For users weighing options, this grip sits between standard compact grips and heavier production-focused power solutions. It provides a practical upgrade for extended sessions and direct mic connectivity, without moving into full cinema-style rigs. If you want a lighter setup with minimal fuss, you might opt for a simpler grip and separate audio routing solutions. If you need all-day power with robust heat protection and built-in mic passthrough, this model offers a balanced approach.

Final decision

Is it worth it?

Worth considering if you plan long recording sessions, value a direct mic connection, and want the flexibility of charging the grip whilst using the camera. It may not be the best match if you prioritise ultra-portable minimalism or have limited power needs.
