The Tether Tools ONsite D-Tap to AC Power Supply (220V International Version) is a compact and portable power inverter designed for professional photographers and videographers who need to power their gear on location, particularly in countries with 220V AC power standards.
This device is the core of the Tether Tools ONsite power system. It converts the DC power from a high-capacity professional battery (like a V-mount or Gold-mount battery) into standard AC and USB power, allowing you to run or charge a wide range of equipment without relying on a wall outlet.
Key Features and Specifications:
International Power Output: This specific version is engineered to provide a stable 220 VAC (±10%) output, making it compatible with the power standards of most countries outside of North America and parts of Central and South America.
D-Tap Input: The power supply connects to any battery that has a standard D-Tap (also known as P-Tap) connector. This includes V-mount and Gold-mount batteries, which are the industry standard for cinema and broadcast equipment.
Multiple Ports: It features a total of six outlets:
Two AC outlets: These allow you to plug in devices that require standard wall power, such as a laptop power adapter or a camera battery charger.
Four USB-A ports: These provide 5V / 2.1A each, with a maximum combined output of 6.2A, allowing for fast charging of smartphones, tablets, and other USB-powered devices.
Power Output: The unit provides a total output power of 200W. This is suitable for most professional photo and video gear, but it's important to be aware of the limitations.
Recommended for: Laptops, camera battery chargers, tablets, phones, and small LED lights.
Not recommended for: High-draw devices like desktop computers, large strobes, or hair dryers.
Portability and Travel: Weighing just around 0.65 lbs (290g), this power supply is very lightweight and portable. Tether Tools also highlights that it has no TSA travel restrictions, making it easy to carry on to a flight.
System Integration: It is designed to work seamlessly with other Tether Tools products. When paired with a V-mount battery and the ONsite Versa V-Mount or ONsite Aero V-Mount, it can be securely attached to a light stand, C-stand, or a Tether Table Aero, creating a safe and organized tethered workstation.
Cooling Fan: The unit includes a temperature-controlled fan that activates to prevent overheating. It's good to be aware that the fan's noise level might be audible and could be picked up by sensitive microphones during a video shoot.

The 220V vs. 110V Difference:
The primary difference between the 220V international version and the 110V US version is the output voltage of the AC outlets. The internal components are configured to produce the specific voltage for the intended market. It's crucial to purchase the correct version for your location and the devices you intend to power.
