Power Take-off Gun Adapter – EV Discharge

Product Overview

The Power Take-off Gun Adapter is a compact GB-standard adapter that plugs into a vehicle’s GB charging inlet to draw AC power out of the battery — a practical take-off point for powering tools, appliances or equipment from an EV. It is supplied to accessory distributors, fleet operators and OEM buyers who need a simple, robust discharge adapter rather than a full V2L gun.

Built to the GB/T 20234 and GB/T 2099.1 standards, the adapter is rated for single-phase 220V AC at 10A with a maximum load of 2.2kW. Its pin-and-socket contacts are welded for a stable, low-resistance connection, and the housing measures just 57.1 × 52.0 × 76.1mm, making it easy to store in the vehicle.

Key Features & Advantages

GB/T 20234 Take-off Interface

The adapter is designed to the GB/T 20234.1, GB/T 20234.2 and GB/T 2099.1 standards, ensuring correct mating with GB-standard vehicle inlets. It provides a dependable take-off point for drawing AC power from the vehicle.

10A, 220V AC, 2.2kW Output

Rated for single-phase 220V AC at 10A, the adapter supports a maximum load of 2.2kW — enough for lighting, power tools, laptops and similar equipment on site or on the road.

Welded Pin and Socket Contacts

Contacts are welded rather than crimped for a stable, low-resistance joint. Insulation resistance exceeds 500 MΩ and the assembly withstands 2200V AC for one minute at under 5mA.

10,000-Cycle Mechanical Life

The adapter is rated for 10,000 mating cycles, so it stands up to repeated plug-in use in workshops, depots and field service without losing contact integrity.

Compact, Robust Housing

At 57.1 × 52.0 × 76.1mm the adapter is small enough to live in the vehicle, and it operates from -30℃ to +50℃. OEM and ODM orders start at a MOQ of 100 units with a 30–45 day lead time and a 24-month warranty.

Application Scenarios

Vehicle Power Take-off

Drivers and technicians use the adapter to tap stored energy from a GB-equipped EV for tools and equipment on site, avoiding the need for a separate generator. It can be paired with a GB Standard AC Charging Gun Cable for charging when the take-off is not in use.

Fleet and Service Vehicles

Service and utility fleets running GB-standard EVs fit the adapter as a low-cost way to power equipment at remote jobs. Its welded contacts and 10,000-cycle rating suit frequent daily use.

Accessory Distributors

For distributors of EV discharge accessories, the take-off adapter is a compact, easy-to-ship SKU. Learn how V2L discharge works in our guide to EV discharge gun technology.
