Overview

300 watt (330VA) pure sine wave ups inverter with charging, 12V, 24V, 48V DC input voltage can be selected, high efficiency and lightweight sine wave inverter worth buying.

Note: If the load is a refrigerator or similar to a refrigerator with a compressor, it is recommended that the power of the inverter is more than 10 times the power of the load.

Features:

UPS inverter with pure sine wave output (THD＜3%)
Built-in 3-stages battery charger, allow to run loads while charging.
Automatically switch with a ultra-fast switching time.
Pure sine wave ups inverter uses soft-start technology.
High efficiency-converts the battery’s available power.
90% pure sine wave output, low distortion, waveform and main power line AC waveform are basically the same, equipment accuracy is small, low interference, low noise, strong load capacity, can meet any type of AC load, without damaging the load.
Aluminum shell with good heat dissipation and strong shock resistance.
Optional crocodile clip and cigar lighters, easy to connect batteries or vehicles' batteries.
Uninterruptible power supply with USB charging port: 5V, ideally qualified for powering your phone, laptop, pc, etc.
LED indicators for power and protections.
Switch-mode design in 300 watt ups inverter, easy to use.
Intelligent fan for cooling, long use life.

Tips：Pure Sine Wave VS Modified Sine Wave

The pure sine wave output is equal to or better than our grid power. Different inverter manufacturers may use different terms, which mean the same thing, like true or full sine waves. As you can see in the figure below, 120VAC pure sine wave voltage rises evenly at the smooth phase angle and decreases evenly at the smooth angle. When it passes through 0V, its polarity also changes immediately.

Form of pure sine wave

With the modified sine wave, the voltage rises and falls sharply. The angle of the phase is not smooth and can change suddenly, causing the waveform to look much like a staircase. The modified sine wave also briefly stays at 0V before changing polarity. You cannot get an accurate voltage reading with a standard voltmeter, you must use a "True RMS" meter to read the modified sine wave.

Very lightweight and easy to carry

This UPS inverter is so useful for people like me who often need to use electronic devices outdoors! It's only 300 watts, but it's more than enough to meet my power needs. What attracts me most is its portable design, which is very lightweight and easy to carry. Whether I'm camping, traveling, or in an emergency, it ensures that my devices always have power.
