Dummy Battery Kit for Q4 Speedlight - Continuous AC Power for Studio

In this review the NEEWER NT-Q4 Dummy Battery Kit is presented as a practical solution for photographers and videographers who need continuous power for the Q4 outdoor flash strobe. The bottom line: it replaces frequent NB-Q4 lithium battery swaps with an AC power adapter and long cables so the light can run continuously for studio, vlogging, live streaming, or extended shoots. For anyone who values uninterrupted operation over portability, this kit removes battery anxiety while adding an intelligent protection layer.

Key Features

• Full compatibility: Designed specifically for the Q4 flash strobe, the dummy battery fits in place of the NB-Q4 so the unit functions as if powered by its standard battery.
• Continuous AC power: The included power adapter and cable supply steady 25V 10.4A output so the flash can operate for long sessions without swapping batteries.
• Intelligent Safety Protection: Built-in safeguards protect against overheating, overcurrent, overvoltage, electric shock, and short circuits to extend device life and reduce risk during prolonged use.
• Extended cable length: A combined 16.4ft of cable (9.8ft for the AC cord and 6.6ft for the adapter output) gives freedom to position the flash away from power outlets in a studio or indoor setup.
• Durable construction: Pure copper conductors and PVC coating on the cables improve conductivity and resist frequent bending and coiling for reliable daily use.
• Simple installation: Insert the dummy battery into the Q4 lamp body and connect to a standard outlet using the supplied US plug adapter for immediate power.

Who It's For

The NT-Q4 dummy battery kit is best for studio photographers, livestreamers, vloggers, and filmmakers who predominantly shoot indoors and need continuous, reliable flash power without the interruption of changing NB-Q4 batteries. It is especially useful for controlled environments where mobility is limited and sessions run for long periods.

Those who need fully portable lighting for remote outdoor shoots, or who must preserve battery-operated mobility, should consider keeping spare NB-Q4 batteries instead, since this kit requires access to AC power and is not intended as a travel battery replacement.

Pros & Cons

Pros

• Eliminates frequent battery swaps for uninterrupted studio and streaming sessions.
• Comprehensive protection system reduces risk of damage from electrical faults or overheating.
• Long, flexible cables let you place the flash away from outlets without strain.
• Durable copper and PVC cable construction for repeated use.

Cons

• Requires an AC outlet, so it is not a substitute for battery power in remote outdoor shoots.
• Users should update Q4 firmware when necessary and observe cooling breaks after intense use to avoid automatic shutdown.
