VortiPower VP20

Electric cars carry large batteries that mostly sit idle once parked. The VortiPower VP20, presented as a Kickstarter project, is built to tap that reserve: the maker describes it as an external discharge device that plugs into a Tesla and feeds power out to other equipment.

Power output

The maker says the VP20 supports 3,500W of output, enough, by its account, for household appliances, outdoor gear and backup power during emergencies. Compatible vehicles are listed as the Tesla Model 3, Model Y, Model S and Model X.

Integration and monitoring

According to the maker, the device integrates with the Tesla's systems without requiring vehicle-side settings or special installation. A smart LCD display shows power consumption in real time, intended to help users manage how much energy they draw from the car.

Plugs, safety and build

• Connector support: NACS (North American Charging Standard) and CCS2 (European standard), per the maker
• Certification: UL458, according to the maker
• Design: portable, with durable materials the maker says maintain stable operation in harsh environments

The maker frames the VP20 as part of a broader idea of using EV batteries as external power sources, supporting outdoor use and preparedness for Tesla owners.
