NEEWER Q4 Battery Pack 21.6V 2800mAh Li-ion - Reliable Studio Backup

In this review of the NEEWER Q4 Battery Pack the bottom line is simple: photographers who already own the NEEWER Q4 400Ws 2.4G TTL flash will find a dependable, high-capacity replacement battery that restores full mobility without buying a whole flash. The reviewer found the single biggest reason to buy is the sustained run time - a 21.6V/2800mAh Li-ion cell rated for up to 400 full power flashes on a single charge - which makes it a straightforward way to keep a Q4 flash working through long shoots. This review focuses on fit, runtime, safety features, and portability.

Key Features

• Model compatibility: Designed exclusively for the Q4 flash, it ensures proper fit and electrical match with the NEEWER Q4 400Ws 2.4G TTL unit for plug-and-play replacement.
• High capacity cell: The 21.6V, 2800mAh Li-ion polymer battery offers extended run time so a single session is less likely to be interrupted for charging.
• Up to 400 full power flashes: One full charge can deliver up to 400 full power pops, which is useful for long on-location or studio shoots where changing batteries is inconvenient.
• Built-in protections: Integrated safeguards against over charge, over discharge, over voltage, over current, and overheating help protect the flash and improve reliability during heavy use.
• Lightweight and portable: At about 0.9lb (410g) this replacement battery is easy to carry as a spare without adding significant weight to a kit bag.

Who It's For

This battery is aimed squarely at photographers and content creators who already own the NEEWER Q4 400Ws 2.4G TTL flash and need a direct replacement or spare power source to extend shooting time. It is particularly useful for wedding photographers, portrait shooters, and location shooters who require many full-power flashes between charges.

It is not for users who do not already have a Q4 flash, since the pack is exclusively compatible with that model and the charging adapter is not included. Buyers who need a multi-brand universal battery or a charging kit should look elsewhere or plan to reuse the original Q4 adapter.
