TAVT LP-E17 Dummy Battery Power Adapter for Canon EOS Series
Product description
What this is and what it does
The TAVT LP-E17 Dummy Battery is a power accessory designed to run Canon cameras from a constant external power source. It targets a broad range of Canon bodies listed in the product name and description, offering a method to keep cameras powered during long shoots, interviews, live streams or studio-style setups where swapping batteries mid-shot is inconvenient.
How it helps in real-world use
On paper the unit works with a USB Type-C to PD LP-E17 setup, delivering stable power for extended recording sessions. Practically, this means you can shoot portraits, product demos or vlogs without worrying about battery depletion while remaining tethered to a wall outlet or a big portable power source. The device is intended to be compatible with the common LP-E17 camera line-up, which many Canon shooters rely on for compact bodies and user-friendly ergonomics.
What makes it notable
A couple of design points are worth noting. The dummy battery features a fully decoded output, which aims to avoid irritating pop-up alarms that sometimes interrupt capture when external power is used. It also incorporates an advanced protection system to guard against overcharging, short circuits, overheating and overcurrent, giving a sense of reliability during longer sessions.
Limitations and cautions to keep in mind
It’s important to note that the package requires a 9V or 12V AC adapter to function. If you connect it to a 5V 2A supply, it will not operate. This constraint means you’ll want to ensure your power set-up matches what the unit expects before relying on it for a full day of shooting. The included contents are straightforward: the Type-C to PD LP-E17 dummy battery, a cable and an instruction manual. There’s no mention of a power brick in the box, so you’ll need the compatible AC adapter separately.
Who it’s for
This accessory is suited to videographers and photographers who prioritise continuity over frequent battery swaps. It’s particularly practical for studio work, live streaming, or interview setups where a stable external power source helps maintain consistent performance and framing.
Who it isn’t ideal for
If you’re shooting on the move or in locations where a wall socket or sufficient power supply is hard to obtain, this solution may feel limiting. It also isn’t designed to replace all scenarios where high-end, dedicated cinema power solutions are required. If you frequently run 9V/12V power sources aren’t readily available, a standalone battery alternative could be more flexible.
Before you buy: practical checks
- Confirm your Canon model compatibility from the list in the product name and description.
- Plan your power setup: ensure you have a 9V or 12V AC adapter that works with the dummy battery’s input requirements.
- Consider the cable management on set, the coil is described as tangle-free, but length and routing can still affect your workflow.
- If you rely on alarms or notifications during recording, the decoded output is a perk worth appreciating.
How it compares to other approaches
Compared with standard LP-E17 batteries, this dummy battery approach trades a bit of portability for continuous power and reduced interruptions in long shoots. For many users, the value lies in keeping a steady power supply during filming or streaming rather than the flexibility of quick battery swaps. If maximum mobility is essential, you might prefer a traditional battery solution or a compact, self-contained unit that doesn’t require fixed power.
Decision point: is it worth it?
Final verdict
Worth considering if you prioritise uninterrupted recording sessions for compatible Canon bodies and you already have or plan to source a 9V/12V AC supply. If your shooting context is mainly on the move or in locations without reliable mains power, you may want to explore alternatives that don’t hinge on a fixed power input. For studio work, this can be a sensible companion to a reflector, light, or mic setup, helping you avoid mid-shot interruptions without needing to swap batteries.
Practical FAQs
- What cameras does it support? It lists Canon EOS RP, R10, R8, R50, R100, M3, M5, M6, M6 Mark II, Rebel and Kiss/SL series in the provided description.
- Do I need any extra parts? Yes, a 9V or 12V AC adapter is required, a 5V 2A adapter will not work.
- Are there built-in protections? The unit includes an advanced protection system designed to reduce overcharging, short circuits and overheating.
- Is the cable prone to tangling? The description mentions a tangle-free, spring-coiled cable for easier handling, though real-world handling may vary by setup.
- How do I know if this is the right external power solution for me? If you shoot long sessions and want a reliable external power source for compatible Canon bodies, this approach can simplify power management and reduce battery swaps, otherwise, assess your need for mobility against continuous power.
