NEEWER 100Ws TTL Round Head Flash for Canon (Z3R-C) – 2.4G, HSS, 3000mAh Battery
Product description
What it is and who it’s for
The NEEWER Z3R-C is a 100Ws TTL round head speedlite designed for Canon cameras, with 2.4G wireless control and high-speed sync up to 1/8000s. It’s aimed at photographers who want a compact, controllable secondary light with quick recycle times and rechargeable power. If you value a round head for more natural falloff and a touchscreen for quick tweaks, this unit may fit into a small studio or on-location setup.
How it performs on paper

On paper, the flash offers 1/256–1/1 power in 0.1EV steps, a 6000K colour temperature for a neutral skin tone, and two dimmable LED modelling lamps to preview light. It supports firmware upgrades for compatibility, and displays a 2.8" full colour touchscreen for control. The cooling system is designed to sustain 70–100 consecutive full-power flashes across a focal length range of 28–105mm, with a quartz flash tube rated for up to 100,000 flashes.
Battery life and power management


Equipped with a 3000mAh lithium battery, it promises up to 500 full-power flashes and around 1.7 seconds recycle time. Recharging can be done via USB-C or a USB 5V/2A dock, and an external power pack is supported (not included). For those who shoot events or weddings, the battery capacity is a meaningful part of the kit’s practicality, though real-world numbers can vary with power settings and weather.

Wireless control and compatibility
The 2.4G system supports 5 groups, 32 channels and 99 IDs, enabling a degree of remote control with compatible transmitters and other NEEWER Q System components. It’s compatible with Godox Xpro, X3 and X2 transmitters, and Sekonic RT-GX meters as a secondary strobe. Important to note: you cannot use the Q and X systems simultaneously.
Compatibility with Canon cameras

This flash lists broad Canon compatibility, including R10, R8, R7, R6 II/ R6, R5 II/ R5, R5, and older bodies up to 7D Mark II and 5D series, among others. The note for EOS R50 users is notable: this unit requires an AD-E1 adapter (sold separately) to function due to missing legacy hotshoe contacts on the R50.


What stands out and where it may fall short
What stands out is the combination of a high-speed 1/8000s sync, a round head for nicer catchlights, a large touchscreen, and a robust 3000mAh battery offering a claimed 500 full-power flashes. The built-in modelling lamps are useful for previewing light if you’re balancing ambient. On the downside, the reliance on adapters for certain Canon bodies (R50) and the fact that the Q and X systems can’t run together may complicate more complex setups. If you prioritise a compact, feature-rich flash with wireless capability, this could be a strong candidate, if you need seamless cross-brand compatibility or a simple, plug-and-play setup, you may want to check other options.

Practical use and who it’s for
Ideal for enthusiasts and professionals who shoot portraits or events and want fast recycling, a controllable power range, and the ability to preview light with modelling lamps. It’s best suited to Canon bodies listed in the compatibility notes and users who are comfortable managing a multi-system wireless setup. If you mostly shoot with a single camera body and don’t need the expansive ecosystem features, you might find a simpler unit more straightforward.
Before you buy: check these points



- Ensure your Canon body is among the listed compatible models or that you’re prepared to use the appropriate adapter for EOS R50.
- Consider whether you need 2.4G wireless sync with specific transmitters and if you’ll rely on the Q vs X system compatibility.
- Confirm that the battery life and recharge options align with your typical shooting sessions and power accessibility on location.
How it compares to other approaches
If you’re weighing a flash with such power, you’ll find this unit sits between entry-level and mid-range speedlites: it offers modern features (touchscreen, HSS, round head) that aren’t always present in older models. For those who don’t need TTL or wireless sync, a simpler, non-TTL unit could be cheaper. If you frequently need high-speed sync or plan to build a more elaborate wireless setup, this option provides a reasonable feature set without jumping to pro-grade pricing.

Decision section
Is it worth it?
Worth considering if you prioritise a round head with accurate modelling previews, a solid battery, and 2.4G control within a Canon-compatible system. It may be less ideal if you require seamless cross-brand use or if you shoot with a Canon body not listed in the notes and don’t plan to use an AD-E1 adapter.
FAQ
- Will it work with my Canon model not listed explicitly? Check the compatibility notes and consider an adapter if needed.
- How many flashes can I expect from a full charge? Up to about 500 full-power flashes, depending on usage and settings.
- Can I use the Q and X systems together? No, the device supports either Q or X system control, not both at the same time.
