BESTEK 300W Power Inverter 12–17V to 110V — Compact Car Adapter with 2 AC Outlets & 2 USB (Aluminum, 700W Peak)

BESTEK's compact 300W power inverter converts 12–17V DC from your vehicle into two 110V AC outlets plus two USB ports for powering laptops, chargers, and small appliances on the road.

Designed for modern vehicles (including Tesla compatibility across 11–17V), this lightweight inverter delivers 300W continuous power and a 700W surge for short peaks. The unit pairs two grounded AC sockets with dual 4.8A USB outputs inside a rugged aerospace aluminum housing and includes safety features such as a 40A fuse, thermal fan control, and multiple voltage protections. ETL-certified and backed by a 5-year warranty, it’s built for reliable travel, work trips, and mobile charging needs.

How much power can I run from this inverter while driving?

This inverter supplies up to 300 watts of continuous AC power and can handle brief surges up to 700 watts for startup loads. It’s suitable for laptops, small kitchen gadgets, phone chargers, portable lights, and similar low-draw devices.

• 300W continuous output; 700W peak/surge capability
• Two grounded 110V AC outlets for simultaneous devices
• Two USB ports delivering combined 4.8A for phones and tablets
• Not intended for heavy appliances like full-size fridges or power tools

What makes this safe to use in modern cars, including EVs?

BESTEK upgraded the inverter to accept an 11–17V input range so it works with many vehicles and electric cars. Built-in protections—over/under voltage, overheat, short-circuit, and a 40A fuse—help protect both the inverter and connected devices.

• 11–17V input compatibility for a wide range of vehicles including Tesla
• 40A inline fuse for circuit protection
• Automatic thermal fan: quiet operation at low loads, faster cooling when hot
• ETL certification confirms tested safety standards

Is it convenient to carry and use during travel or camping?

The inverter’s compact, iPhone-sized footprint and lightweight build make it easy to stash in a glove box or backpack. A 32-inch cigarette lighter cable lets you plug in from different seating positions without reaching under the dash.

• Ultra-compact design—easy to pack for trips or overnight stays
• 32-inch plug cord for flexible placement in the vehicle
• Durable aerospace aluminum shell resists dents and adds heat dispersion
• Two AC outlets plus two USB ports reduce the need for extra adapters

Who is this for? Drivers who need reliable AC and USB power away from wall outlets will find this BESTEK inverter useful: remote workers charging laptops on the road, families keeping small appliances running during travel, campers powering lights and small devices, and EV owners wanting compatible vehicle power conversion. If you need continuous high-wattage power for heavy tools or large appliances, consider a higher-capacity inverter; for everyday mobile charging and small electronics, this is a compact, safety-minded choice backed by a 60-month replacement warranty and 24/7 customer support.
