YSOLX 300W Car Power Inverter — Portable Charger with 2 AC Outlets & 4 USB Ports, Compact for Travel

YSOLX 300W Portable Charger Car Power Inverter converts a vehicle’s 12V DC socket into two 110V AC outlets plus four 24W USB-C/A ports for charging laptops, cameras, phones, and small appliances on the go.

Compact and lightweight, the YSOLX 300W inverter gives you multiple charging options from a car cigarette-lighter socket without bulky setup. Built for road trips, camping, emergency tops-ups, and mobile work, it balances convenience with safe operating limits so you can power essential electronics while preserving vehicle battery health.

How much power can I safely run from this car inverter?

The inverter supplies up to 300 watts from a 12V DC input—enough for laptops, small TVs, game consoles, and most chargers. It is not intended for high-draw devices such as hair dryers or space heaters, which will exceed the inverter’s rated output and trip the fuse.

• Maximum continuous power: 300W
• Intended for low-to-moderate power electronics (laptops, cameras, lights)
• Not suitable for high-wattage heating or heavy motor loads
• Built-in protection prevents damage from overloads and short circuits

How do I use the YSOLX inverter in a car or while camping?

Plug the inverter into your vehicle’s 12V cigarette-lighter socket or compatible DC outlet and turn on the unit; it converts the DC supply to two 110V AC outlets and four 24W combined USB-C/A ports. This simple plug-and-play setup makes charging multiple devices easy during travel or at campsite parking without additional wiring.

• Plug into a 12V car socket—no battery clamps required
• Use AC outlets for laptops or small appliances and USB ports for phones/tablets
• Monitor device load and avoid powering high-wattage items
• Portable size fits glovebox, backpack, or center console for quick access

What safety and cooling features protect the inverter and my devices?

YSOLX designed this inverter with an upgraded intelligent cooling fan that runs quietly while managing internal temperature during extended use. The unit also includes standard protection circuits that guard against overload, short circuit, and thermal faults to help prevent damage to both the inverter and connected gear.

• Smart cooling fan for quieter, more stable operation
• Overload and short-circuit protection to reduce risk of failure
• Thermal management helps extend component life during continuous use
• Fuse-protected output to prevent excessive current draw

What devices are best suited for the four USB ports and dual AC outlets?

The USB-C/A ports deliver a combined 24W that’s ideal for smartphones, tablets, small power banks, and accessories. The two 110V AC outlets are best for devices that require standard household power but remain within the 300W cap—think laptops, small TVs, DVD players, and portable fans.

• USB-C/A: charge phones, tablets, e-readers, cameras
• AC outlets: laptops, game consoles, portable media players
• Not recommended for hairdryers, electric heaters, or large kitchen appliances
• Perfect for multiple-device charging during travel or mobile work

Who is this for? The YSOLX 300W Portable Charger Car Power Inverter fits travelers, weekend campers, ride-share drivers, and anyone who needs reliable multi-port charging from a vehicle. It’s also useful for mobile professionals who require laptop and device power between stops, and families who want to keep devices, lights, and small appliances running during outdoor activities or brief power interruptions. If you need compact, fuss-free power from your 12V outlet without heavy-duty electrical installs, this inverter is a practical choice.
