The best auto-inverters for refrigerator backup power

The Choetech CJ-1600M inverter is designed to power various electrical appliances from a 12 V car battery. The converter is connected to it using crocodile wires.

The device is designed to handle loads with a total power of up to 800 W. But on a short-term basis it pulls twice as much overload (up to 1600 W) - this allows it to withstand high inrush currents. At the output, the user receives a pure sinusoidal voltage, which is important for the safe power supply of sensitive equipment (control equipment of a heating boiler, refrigerator, etc.).

The model was equipped with a single universal socket with an output voltage of 230 V. There are no other connectors on board the auto-inverter. But the Choetech CJ-1600M has a built-in info screen to display information about the current voltage output.

The positive qualities of the inverter include the high efficiency of voltage conversion (up to 93%), the presence of a built-in cooling fan and LED indication of operating status. A multi-level protection system against electrical breakdowns (overload, high and low voltage, short circuit, overheating) is also installed here. Finally, the model impresses with its lightweight design - the device weighs about 800 g.

The Demuda DMDPSW-800W inverter comes to the rescue both at home and when traveling by car. The device helps power gadgets and household appliances from 12-volt car batteries, converting their voltage to a standard “socket” value of 230 V.

The 800 W model is the youngest in the line of Demuda DMDPSW series inverters. The main thing about it is the correct sinusoidal output voltage, which is optimal for powering sensitive equipment. The output voltage changes evenly and without sudden changes, and in terms of parameters it is as close as possible to conventional power outlets.

It is supposed to control the operation of the auto-inverter using the data on two information screens. The first shows the input voltage parameters, the second - the output. The model also has two USB ports for easy charging of mobile devices. Any other household appliances receive power from the inverter via a 230 V socket.

Out of the box, the model is equipped with terminal wires for connecting to a car battery and a cable for the cigarette lighter. Finally, it is important to mention the inverter’s electrical safety system - it is tasked with protecting against short voltages and overloading of the device.

The RITAR assortment includes a whole range of auto-inverters with different rated power parameters. The “golden mean” in it is occupied by the RSC-1000 model.

The device is made in the form factor of a kind of aluminum brick weighing a little more than 3 kg. The inverter connection ports are concentrated on the front panel - these are two standard Schuko sockets with an output voltage of 230 V and a signal in the form of a pure sine wave, one USB connector for charging mobile gadgets. There is also a button to turn the device on/off, operation indicators and a small info screen.

In long-term operation , the auto-inverter is capable of servicing a connection power of up to 1000 W. It can withstand peak power surges of up to 2000 W, which is important for starting the compressor of a conventional refrigerator and turning on other equipment with electric motors. To avoid overheating of the internal “filling”, the inverter has a built-in fan.

The device is equipped with an integrated electrical protection system and monitors the charge level of the car battery. When the battery is low, the inverter sounds a warning sound. This significantly reduces the risk of draining the battery and thereby avoids deep discharge.

From the Pulso ISU-1000 inverter you can establish autonomous operation of a refrigerator, one or two laptops, and several lighting points. And all this - overnight.

The model converts 12 V DC voltage into 230 V AC with the correct sine wave, and it is powered by a car battery. In nominal operating mode, the inverter “digests” connection power of up to 1000 W. However, during long-term continuous operation (more than one hour), it is advisable not to exceed 70% of the rated power.

At the moment of starting the power units on board refrigerators and conventional power tools, power surges are observed that exceed the nominal values by 1.5 - 2 times. To compensate for them , the inverter is designed to withstand short-term overloads of up to 2000 W. This is quite enough to guarantee trouble-free starting of electric motors.

Pulso ISU-1000 was equipped with a 230 V socket, a USB A port with an output voltage of 5 V and a current of 2 A, and an RJ-45 connector for connecting a wired remote control. A fan was also built into the device body for active cooling of the “internals”. The inverter safety system covers protection against short circuits, overloads, overheating and reverse polarities.

To convert 12-volt voltage to 230 V , the Mexxsun MXSPSW-1000-12 car inverter is perfect. It is designed for direct connection to the battery using ring terminals.

The model with the “thousandth” set-top box can boast a rated operating power of up to 1000 W. And in the short term, the inverter absorbs power fluctuations of up to 2000 W - this is useful for starting electric motors, during which the starting currents significantly exceed the rated ones. The device is suitable for powering a refrigerator, control equipment of a heating boiler, and will supply power to sensitive electronics thanks to the pure sinusoidal output signal.

Users are kindly provided with two 230 V sockets, but there is no USB socket here. As for operational safety, the inverter has protection against short circuits, overloads, overheating, battery discharge and incorrect connection.

Among the complaints about the model is the heavy design compared to its peers (4.6 kg) - the vast majority of inverter counterparts with a rated power of around 1000 W are produced in lighter cases. However, if the device is stationary, this does not cause any trouble. But this is exactly how it is supposed to use an inverter paired with a battery to independently supply electricity to a home.
