Overview

300 Watt inverter can convert battery DC power to 110/120 Volt or 220/230 Volt AC power, to charge devices like mobile phones, laptops, iPad, Kindles, digital cameras, fans, lights, etc. Equipped with a buzzer reminder device to protect the inverter for home.

Note: Refrigerator or similar to the refrigerator load equipment, need to choose 10 times more power inverter.

Features

Made of high-quality aluminum alloy material and low-pressure casting.
Installed with a pressure-resistant and anti-corrosion thick shell, the power inverter's heat dissipation performance is better, and the output power reaches 90%.
Portable power inverters are suitable for vehicle power supply/mobile phone charging/outdoor electricity.
Equipped with a buzzer reminder device, the inverter will sound an alarm when the battery power is low to protect the inverter from damage due to insufficient voltage.
The power inverter for home comes with an intelligent cooling fan, USB charging interface, and a working indicator light.
Socket specifications can be selected from the United States, the United Kingdom, Australia, South Africa, etc.

Details

Intelligent Cooling Fan

After reaching 45 degrees Celsius, a 300-watt power inverter will automatically start the cooling fan to dissipate the heat, effectively reducing energy consumption. The fan adopts a ball structure, long life, high speed, and low noise.

Aluminum Alloy Shell

With an aluminum alloy shell, the surface of the power inverter is oxidized by sandblasting, which has a better heat dissipation effect. At the same time, it has a beautiful appearance and does not change color permanently.

Multiple-functional Socket

Different socket specifications can be chosen from. 24v power inverters are usually equipped with multiple interfaces, including but not limited to standard three-hole sockets, two-hole sockets, USB interfaces, etc., to meet the charging and power supply needs of different electrical devices.

FAQ

Is the modified sine wave inverter good or not?

Market Prevalence and Applications: At present, most power inverters sold in the market are modified sine wave inverters. These inverters are moderately priced and widely accepted, making them suitable for many low-power electrical appliances. This kind of sine wave inverter can be applied to laptops, small TV sets, audio systems, video cameras, digital cameras, printers, all kinds of chargers, PDAs, game consoles, DVD players, mobile homes, various instruments, etc.
Suitability for Small Electrical Appliances: The modified sine wave power inverter with larger output power can also be used for small electric appliances such as electric hair dryers, electric mugs, kitchen appliances, and so on. However, they are not recommended for inductive load appliances such as refrigerators, and electric drills. Using modified sine wave inverters with these appliances may damage both the inverter and the appliance or shorten their service life.
Recommendations for Inductive Loads: For inductive load appliances, it is recommended to use a quasi-sinusoidal inverter with a large reserve capacity. For example, a 150W refrigerator should ideally be powered by a modified sine wave inverter with more than 3000W capacity to ensure reliable operation and avoid potential damage.

Modified sine wave inverters are a good choice for budget-conscious users and general applications involving low-power devices. However, for inductive loads and sensitive electronics, a pure sine wave or quasi-sinusoidal inverter with adequate capacity is recommended to ensure optimal performance and longevity.

A reliable power for my camper

This 24V 300W inverter is fit for my 24V campervan system. It handles my coffee maker and charges all our devices via the handy USB port without ever getting flustered. It's surprisingly compact, but the housing feels really solid, and I love the universal sockets. Honestly, for the price, it delivers exactly what I needed.

Sufficient for my personal use

This 24V 300W power inverter is very compact and easy to carry. It's still quite sufficient for my personal use. The material of the inverter is good. I hope it can be used for a long time.

300w power inverter works silently

I purchased this 300w power inverter to charge a laptop on a long trip: great performance, lightweight, and no loud noise. The cooling fan was almost completely silent. The USB port provides fast-charging power for my computer.
