Overview

The Neewer CellsII-C is an all-in-one wireless transceiver designed specifically for Canon EOS camera systems, functioning as both transmitter and receiver in a single unit via a TX/RX mode toggle. Its headline capability is high-speed sync support up to 1/8000s — a specification that matters most to photographers working in bright ambient conditions who need to use wide apertures for shallow depth of field while balancing flash fill. Achieving that 1/8000s ceiling requires alignment between the camera's maximum mechanical shutter speed and the flash's IGBT-based duration; when both conditions are met, the CellsII-C removes the trigger as the limiting factor. The multi-channel design allows multiple units to operate in the same space without cross-triggering — a practical necessity in workshop or multi-photographer environments.

The CellsII-C is built for Canon EOS photographers working within the Neewer flash ecosystem — portrait and event shooters using TT-series speedlites or Neewer studio strobes who want reliable wireless triggering without the cost of a higher-end radio system. The all-in-one form factor is a genuine operational advantage: in a kit where every unit can be either a transmitter or a receiver, you carry fewer single-purpose accessories and have more flexibility when your setup changes on the fly. The trade-offs are those common to entry-level triggers: no TTL, no remote power adjustment, and a compatibility envelope that narrows outside the Neewer product family. For shooters who set manual flash power and want a dependable, lightweight way to fire remote flash from a Canon EOS hotshoe, the CellsII-C delivers on that specific brief.

Key Features

All-in-one be a wireless transmitter and a receiver for studio flash/Speedlite Flash, and camera shutter.(Transfer between Receiver and Transmitter just Switch TX and RX)

Featuring multi-channel triggering, stable signal transmission, and sensitive reaction, it gives photographers unparalleled flexibility and control over their strobist setups. The transceiver applies to hotshoe-mounted Canon EOS series cameras.

With Cells II, high speed synchronization is available for most of studio flashes in the market. The max flash synchronization speed is up to 1/8000s. Speedlites and high-speed studio flashes can also achieve high speed synchronization when used with specific models of Canon EOS cameras. Not all camera-flash combinations can achieve high speed synchronization.

Max Sync Speed in Different Camera-Flash Combinations. *: 1/8000s is achievable when the camera has a max camera shutter speed of 1/8000s. 1/8000s is not achievable because some models of Canon EOS cameras has a max camera shutter speed of only 1/4000s;High-speed studio flashes refer to those having a flash duration shorter than 1/2000s and adopting IGBT technology.

Pros & Cons

👍 Pros

The TX/RX switchable design means every unit in your kit can serve as either a transmitter or receiver, reducing the number of accessories you need to carry and swap on location.
Multi-channel triggering lets you isolate your flash system from other photographers' triggers at shared studio sessions or multi-shooter events.
High-speed sync up to 1/8000s opens up the ability to shoot wide apertures in bright daylight with fill flash — a technique that would be impossible at standard sync speeds with most studio strobes.
Native hotshoe compatibility with Canon EOS cameras means no adapter or workaround is needed for mounting the transceiver.
The all-in-one transceiver design simplifies kit management versus carrying separate dedicated transmitter and receiver units of different form factors.

👎 Cons

There is no TTL pass-through or remote power control — flash output must be adjusted manually at the flash unit, which slows down exposure adjustments when the light is positioned away from the camera.
The 1/8000s high-speed sync is conditional on both the camera's maximum shutter speed and the flash's IGBT specification — achieving it requires specific compatible hardware, not just this trigger.
Compatibility is optimized for the Neewer flash ecosystem; performance with third-party flash units using a standard sync port is not guaranteed and requires on-set verification.
No stated range specification in the available product data — maximum reliable trigger distance in real-world environments (interference, reflective surfaces) is not confirmed.
Entry-level build materials are the trade-off for the accessible price point — these transceivers are not built to the same durability standard as professional radio trigger systems.

Frequently Asked Questions

Can the CellsII-C work as both transmitter and receiver from the same unit, or do I need to buy two?

One CellsII-C unit can function as either a transmitter or receiver — you switch modes via the TX/RX toggle on the transceiver itself. For a basic one-transmitter, one-receiver setup you need two units. The all-in-one design means each unit in your kit is interchangeable, so you're not locked into dedicated TX or RX roles if your setup changes.

Will I achieve 1/8000s sync speed with any Canon EOS camera and any flash?

Not automatically. Achieving 1/8000s requires both that your Canon EOS camera's maximum shutter speed reaches 1/8000s (some models top out at 1/4000s) and that the flash you're using has a duration shorter than 1/2000s with IGBT technology. Standard studio monolights without IGBT will sync at lower speeds. Verify both your camera's maximum shutter speed and your flash's technical specifications before relying on 1/8000s in a shoot.

Does the CellsII-C support TTL or manual power control from the transmitter?

Based on the available specifications, the CellsII-C provides wireless triggering — it fires the flash remotely — but does not offer TTL pass-through or remote power adjustment of the flash output. Power control must be set manually on the flash unit itself. This is a standard limitation of entry-level trigger systems.

Which Neewer flash models are confirmed compatible with the CellsII-C?

The CellsII-C is confirmed compatible with the Neewer TT520, TT560, TT680, TT850, Witstro series speedlites, and Neewer studio strobes. It is designed around the Neewer flash ecosystem; compatibility with third-party flashes that have a standard hotshoe sync port will vary and should be tested before a paid shoot.

How many channels does the CellsII-C support, and does that matter in a multi-photographer environment?

The CellsII-C features multi-channel triggering — multiple selectable channels that let you isolate your trigger signal from another photographer's system firing on a different channel. This is directly useful at workshops, multi-photographer events, or studio environments where more than one wireless trigger system is in use simultaneously.
