PiSFAU MT-MX150W 150W 12V Car Power Inverter

The PiSFAU MT-MX150W car power inverter converts vehicle 12V DC to listed 110V AC and provides AC outlets and USB charging for compatible devices. Its stated 150W continuous output suits modest loads, but the listing mixes details about outlet count, USB configuration and dimensions that buyers should verify.

At a glance

Listed for vehicle use, with 12V input and 110V output.
The listing specifies 150 watts output and 300 peak output. Check device requirements against the stated output before use.
The title describes dual USB charging, while a separate specification describes a different USB arrangement. Confirm the selected listing's port configuration.
Modified sine wave output is specified, so this is not a pure sine wave inverter.

Pros and cons

Pros

Compact listed dimensions and low listed weight make it easier to stow in a vehicle.
Provides AC power outlets alongside USB charging, allowing different kinds of small electronics to connect.

Cons

The 150W listed output limits its suitability to lower-power devices and leaves little headroom for equipment with higher draw or startup demand.
Modified sine wave output may not suit devices that require pure sine wave power.

What to know before buying

The listing says the inverter detects faults and turns off output, and describes protection against overheating, reverse connection, under-voltage, over-voltage, overload and short circuit. These are manufacturer claims, not independent verification.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title claims dual USB ports at 3.1A, while the specification text describes 1×2.4A plus 2×QC (18W) ports. Outlet count is listed as three without a clear breakdown. Dimensions also differ between 8.6L x 6.4W x 3.8H centimetres and 8.13 x 6.35 x 3.81 cm; the 150W continuous and 300W peak claims are distinct ratings, not interchangeable. Verify the selected configuration and dimensions before purchase. The listing advises keeping the load below 150W when using a vehicle cigarette-lighter socket, noting that many such sockets use 150A fuses. Its fuse wording is unusual, so check the vehicle manual and inverter instructions rather than relying on that figure.

Who is it for?

A good fit for

Drivers wanting a compact inverter for charging a laptop or phone from a vehicle, provided the combined load stays within the inverter and vehicle socket limits.
Buyers whose devices accept modified sine wave output and need both AC and USB charging options.

Less suited to

People needing more than 150W continuous output or substantial headroom for high-draw equipment.
Devices whose manufacturer requires pure sine wave power.

Customer feedback reports positive experiences charging laptops and phones from vehicles and describes the inverter as convenient and portable. Feedback is mixed on reliability, value and power output. That makes the 150W stated continuous rating and the unresolved configuration details especially relevant for buyers planning regular or higher-demand use. Aggregate ratings lean positive overall, but do not establish performance for any particular device or explain the mixed concerns.

Positive themes

Frequently asked questions

What is the stated output capacity?

The listing specifies 150 watts output and 300 peak output. Treat the peak figure as distinct from continuous output, and check the device's power requirements before connecting it.

What USB ports does this model have?

The details conflict. The title claims dual USB at 3.1A, while specification text lists 1×2.4A plus 2×QC (18W). Confirm the selected listing's actual configuration.

Is this a pure sine wave inverter?

No. The listing describes a modified sine wave output. Check whether connected equipment accepts that waveform.

Can it run a laptop from a car socket?

The listing names laptops as a use and describes a 12V vehicle input, but suitability depends on the laptop's power draw, the inverter's actual output and the vehicle socket's limits.
