CELYYPU CELYYPU001 3500W Pure Sine Wave Power Inverter, 12V DC to 110/120V AC

Pure sine wave output helps power devices that benefit from smooth AC, making this 12V inverter useful for RVs, trucks, and off-grid setups. It converts 12V DC to 110/120V AC and provides three AC outlets plus USB and Type-C charging. Need to check operating status while the inverter is in use? Its LCD displays show input and output voltage, battery load status, and other operating parameters. A wired remote adds power on/off control from a distance.

Worth noting

The pure sine wave output is designed to match the AC waveform of the public grid and supports inductive and capacitive loads. That makes waveform an important point when comparing inverter types, especially for setups powering precision devices over extended periods. The stated output is 3,500 watts, with a 7,000-watt peak output. The manufacturer also states conversion efficiency above 91% during normal operation.

For charging and everyday connections, the inverter has three AC outlets, a 5V/3.1A USB port, and a 30W Type-C port. Hard-wiring terminals offer another connection option. The AC outlets have a maximum output of 15A, devices exceeding 15A should be connected through the hard-wired port. The wired remote is 14.76 feet long, and the inverter includes under-voltage, over-voltage, overload, over-temperature, short-circuit, and reverse-connection protection.

Buyer feedback highlights quiet operation and use with devices such as a computer monitor and TV. Comments on power output are mixed, so treat the stated output rating as a specification rather than a guarantee for every combination of appliances.

How to use it

Connect the inverter to a 12V DC power source for converting battery power to 110/120V AC. In an RV or truck, the AC outlets can serve devices with compatible power requirements, while USB and Type-C ports provide charging connections for smaller electronics. For an off-grid setup, the same DC-to-AC conversion can provide power for AC equipment. Choose the connection based on the device: use the hard-wired port for loads exceeding the outlets’ 15A maximum, and follow the device’s connection requirements when installing it.

The remote’s power control and the display information are useful when the inverter is installed away from the main living or work area. The displays help keep key operating information visible without relying only on the connected appliance to indicate activity.

Tips for day-to-day use

Use the displayed input voltage, output voltage, and battery load status as a quick reference while operating connected equipment. For a mixed set of devices, consider the waveform as well as the power requirement: pure sine wave output is a relevant feature for inductive, capacitive, and precision loads. Keep the 15A outlet limit in mind when choosing between an AC outlet and the hard-wired connection. USB and Type-C ports provide separate charging options, while the three AC outlets are intended for compatible AC devices.

Before you decide

What input does this inverter use? It takes 12V DC power from a compatible source and converts it to 110/120V AC output.

What does the display show? The LCD displays show input and output voltage, battery load status, and other operating parameters. The wired remote also provides power on/off control.

How should I connect a device that exceeds 15A? Use the hard-wired port for devices exceeding the AC outlets’ 15A maximum output. The hard-wired terminals are labeled L, N, and G.

Is it worth it?

For RV, truck, and off-grid use, CELYYPU combines 12V DC conversion with pure sine wave AC, multiple outlet and charging choices, and visible operating information. Its wired remote and hard-wiring option add practical flexibility for installations where the inverter is not right beside the devices. It’s a solid pick if your setup needs a 12V inverter with pure sine wave output and a mix of AC and USB charging connections.
