# OLTEANP OLTEANP-1200W 12V to 240V Pure Sine Wave Inverter

The OLTEANP OLTEANP-1200W is a 12V DC to 240V AC pure sine wave inverter with an LCD status display and USB charging ports. The listing describes 1200W continuous output and 2400W peak output, but other wattage details conflict, so confirm the rated capacity and connection method for your intended load before buying.

## At a glance

- The product description specifies 1200W continuous output and 2400W maximum output, with pure sine wave AC.
- An LCD is described as showing status codes for low voltage, overheating, overvoltage, overload or short circuit.
- USB-A and USB-C charging are listed alongside AC output. The description says USB ports and one AC outlet can be used simultaneously.
- The cigarette-lighter cable is stated to be for loads up to 150 watts, below the claimed continuous inverter output.

## Pros

- Pure sine wave output and a 240V AC output are specified for powering suitable mains-voltage devices from a 12V battery.
- The LCD status readout is reported by customers as clear and easy to read, and the listing says it displays several protection-status codes.
- A USB-A port and 36W USB-C output provide charging options without using an AC outlet.

## Cons

- The cigarette-lighter connection is limited by the listing to 150 watts, so it cannot deliver the stated 1200W continuous output.

## Before you buy

- The listing says to connect to a 12V battery, not to the mains grid or directly to a solar panel. It also says not to run the inverter when the car is switched off, to avoid reversed polarity, and to keep it in a cool, dry place away from direct sunlight.
- The product description specifies a 150-watt maximum for the cigarette-lighter cable. Do not assume that connector supports the inverter's full claimed output.
- Listing details conflict or remain unconfirmed: the title and product description claim 1200W continuous and 2400W peak, while a feature bullet says 600W, a details field lists 2499.99 watts and another lists 2500 peak watts. The capacity is also given as 2500 without a unit. Dimensions differ between 30L x 30.5W x 12H centimetres and 203\*102\*58MM. Confirm the correct rating and physical size for the selected version before purchase.

## In the box

- Power inverter (Included)
- Alligator clips (Check selected pack): Listed in a feature description of what the buyer gets, but not in the explicit box-contents field.
- Car cigarette-lighter connector (Check selected pack): Listed in a feature description of what the buyer gets, but not in the explicit box-contents field.
- User manual (Check selected pack): Listed in a feature description of what the buyer gets, but not in the explicit box-contents field.

## A good fit for

- Drivers seeking 240V AC from a 12V battery for compatible small appliances or electronics, after confirming their load stays within the correct inverter rating.
- Buyers who want a status display and separate USB-A and USB-C charging connections.

## Less suited to

- People needing full inverter output through a cigarette-lighter socket, since the listed cable limit is 150 watts.
- Buyers who need an unambiguous, verified wattage or physical-size specification without checking the selected listing.

## Customer feedback

Customer feedback highlights perceived reliability, a readable display, portability and solid build quality. Customers also report mixed experiences with power output and connectivity, including concerns that some units do not provide enough power and that plugs are close together. These perceptions are relevant if the inverter will run a demanding load or several connected devices. The listing's conflicting wattage claims make it especially important to confirm the selected unit's rating and layout rather than treating positive feedback as proof of capacity.
- Positive themes: Customers describe the inverter as reliable and the display as clear and easy to read.
- Positive themes: Customers also praise its portability and build quality.
- Mixed feedback: Feedback on power output is mixed. Some customers find it powerful, while others say it does not deliver enough power.
- Mixed feedback: Connectivity feedback is mixed, with some customers reporting that plugs are too close together.

## Frequently asked questions

### What input and output voltages does the listing give?
It lists 12 Volts \(DC\) input and 240 Volts \(AC\) output.
### How much power can it supply?
The product description states 1200W continuous and 2400W peak, but other listing fields give inconsistent wattage figures. Confirm the rating for the selected version before relying on it.
### Can the cigarette-lighter cable supply the full inverter output?
No. The listing says the cigarette-lighter cable is designed for use up to 150 watts. It does not support the claimed 1200W continuous output.
### What does the LCD show?
The listing says it shows low-voltage, overheat, overvoltage, overload or short-circuit status codes.
### What connections are described?
The listing describes AC outlets, a USB-A output rated at 5 V / 3 A \(max.\) and a 36W USB-C output. The feature text does not consistently specify the number of AC outlets.
