SMIKVIN 300W Car Power Inverter 12V to 110V with 2 AC Outlets, 4 Fast USB Ports & LCD Voltage Display

The SMIKVIN 300W Car Power Inverter converts a vehicle's 12V cigarette lighter into a reliable 110V AC source with two switched outlets plus four fast USB ports for charging multiple devices on the go.

Whether you're on a road trip, camping, or dealing with a roadside emergency, this compact inverter provides a practical way to run laptops, charge phones and power low-wattage appliances from your car. Built for portability, it packs dual AC sockets and a mix of PD and QC fast-charging USB ports into a smartphone-sized, flame-resistant housing, while an LCD shows real-time voltage for safer use.

How can I power my laptop and phone simultaneously in the car?

This inverter supports continuous output up to 300W, letting you run a laptop from an AC socket while charging phones and tablets from the USB-C PD and QC USB-A ports. Use the independent AC switches to control which outlet is active and avoid unnecessary battery drain.

• Two 110V AC outlets with separate on/off switches for selective use.
• Two USB-C PD ports, each up to 36W for fast laptop or tablet charging.
• Two USB-A QC3.0 ports, each up to 30W for rapid phone charging.
• Total combined load must remain below 300W to avoid overload protection.

What safety features protect my devices and vehicle battery?

SMIKVIN built the inverter with multi-layer safeguards and active cooling. A temperature-regulated fan and six protection layers guard against overheating, short circuits, and incorrect voltages so your devices and vehicle electronics stay protected.

• Auto-adjusting cooling fan reduces heat during sustained use.
• Overload, overheat, and short-circuit protection automatically cut output.
• Input over-voltage and under-voltage protection prevents battery damage.
• Durable ABS+PC flame-resistant shell resists heat and shocks.

What does the LCD voltage display tell me and why is it helpful?

The built-in LCD shows real-time input and output voltage so you can monitor battery health and device draw at a glance. Knowing the exact voltages helps prevent running the car battery too low and alerts you to abnormal power conditions before devices are affected.

• Monitors vehicle battery input voltage to avoid deep discharge.
• Displays output voltage for connected AC devices to confirm proper operation.
• Provides a quick status check while charging multiple devices simultaneously.
• Clear readout helps troubleshoot power issues during travel or emergencies.

How portable is this inverter for travel and outdoor use?

The unit is designed to be compact—about the size of a large smartphone—so it stores easily in a glovebox, backpack, or center console. Its rugged, heat-resistant casing and stackable profile make it a convenient choice for frequent travelers and campers who need reliable power without bulky gear.

• Pocket-sized footprint for convenient storage in cars and bags.
• Shockproof, flame-resistant ABS+PC housing for durability outdoors.
• Stackable design minimizes space when packing multiple units or accessories.
• Includes continuous customer support for setup and troubleshooting.

Who is this for? The SMIKVIN 300W Car Power Inverter suits drivers who need a compact, safe way to run laptops, recharge multiple devices quickly, or power low-wattage appliances while away from wall power. It’s ideal for road-trippers, remote workers, campers, and anyone who wants a dependable, vehicle-powered backup for electronics—provided the total connected load stays under 300W. Avoid using high-draw appliances like hair dryers or microwaves, and consult the inverter’s display and switches to manage power efficiently.
