Most people assume that connecting multiple wires to a battery requires complex soldering, yet clever adapters often handle the heavy lifting for you. After analyzing these options, I find that only one serves as a genuine electrical bridge. I have carefully reviewed their specifications to help you avoid a messy setup. Here is my honest, ranked comparison of these power solutions and security hardware options.
1. FOMITO 2-Sided NPF Dummy Battery Cross-Shaped to D-tap Power Cable with USB-C Output Output Connecting V-Mount Battery for Field Monitor, Wireless Video Transmission, LED Light, Camera, Smartphone
The FOMITO system earns the top spot because it effectively manages power distribution without requiring you to splice cables yourself. By using a cross-shaped design, it allows for multiple peripherals to draw from a single V-mount source.
I find this approach remarkably efficient for field production where you need to run an LED light and a monitor simultaneously. It avoids the clutter of individual adapters by consolidating your power input into a single, reliable hub.
The primary limitation is that it strictly serves the NPF standard, so ensure your equipment matches that specific mount before purchasing. In my view, it is the only sensible choice for someone managing a complex rig.
Users appreciate the clean cable management provided by the dual output ports.
The build quality handles consistent power draws without excessive heat buildup.
It remains a favorite for those running multiple monitors on a tight production schedule.

2. ThorBolt X1 Smart Keyless Entry Fingerprint Door Lock with Keypad, Black | With Apple Home Key, 8x AA Alkaline Batteries, 6 Ways to Unlock, Works with HomeKit Over Thread, IP65 Weatherproof
This lock is intended for the homeowner who prioritizes biometric security and wants a modern entry method that leaves physical keys behind. It integrates into a smart home ecosystem, which is ideal if you already use Apple HomeKit to manage your environment.
I personally appreciate the inclusion of eight alkaline batteries, as this provides a long-lasting power reserve for the internal motor. However, it is a door lock rather than an electrical component for daisy-chaining gear.
If you are looking to connect wires for a camera rig, this will certainly disappoint you. It is a sophisticated piece of security hardware that simply does not perform the function of a power distributor.
Buyers frequently mention the convenience of the fingerprint scanner for daily entry.
The weatherproof rating provides peace of mind for exterior door installations.
Setup requires a stable connection to a Thread network to function at its best.

3. ThorBolt X1 Smart HomeKit Keyless Entry Fingerprint Door Lock, Silver | With Apple Home Key, 8x AA Alkaline Batteries, 6 Ways to Unlock, Works with HomeKit Over Thread, IP65 Weatherproof
An unexpected feature of this lock is its compatibility with Apple Home Key, which turns your phone into a digital credential. This represents a major shift in how we handle home access by moving away from traditional mechanical pins.
Much like its black counterpart, this is a specialized security device rather than a power adapter. I wouldn't recommend this if your goal is to distribute voltage to multiple electronic devices.
It is a polished piece of engineering, but it serves a completely different audience than the FOMITO cable. If you need to power a field monitor, you are looking at the wrong aisle of the store.
The silver finish provides a clean look that matches modern door fixtures well.
Integration with existing HomeKit setups is consistent according to most feedback.
The six different entry methods ensure you are never locked out if one system fails.

Choosing Between Them
I recommend the FOMITO 2-Sided NPF Dummy Battery as the only viable choice for electrical projects, as it is the sole product capable of managing power distribution. While the ThorBolt X1 locks are impressive for their intended purpose of home security, they cannot help you connect wires for your camera gear or lights.
You should always verify your amperage requirements before daisy-chaining equipment to a single battery source to ensure your gear operates safely. It is my firm belief that you must select tools based on their actual function rather than their complexity, especially when electricity is involved.
