A small car inverter turns your vehicle into a workable office or charging station. Commuters who take calls from a parking lot, road-trippers keeping tablets alive for the kids, contractors charging tool batteries between jobs and parents running a bottle warmer on a long drive all rely on the same thing: converting the car’s 12V DC power into the 110V AC that household devices expect. A 400W unit is a popular size because it can handle a laptop charger and a few phones at once while staying small enough to live in the glovebox or a door pocket, ready whenever the day moves out of the house.
Pro Chaser sells three versions of its 400W inverter, and they share a lot. All three are rated at 400W continuous and 800W peak, produce a modified sine wave at 110V, have two AC outlets, a 30-inch cord, and a cooling fan that switches on at 113°F (45°C). Where they differ is the USB side. The first has two USB-A ports, the second pairs a USB-A quick-charge port with a 65W USB-C Power Delivery port, and the third has two USB-A ports plus USB-to-USB-C adaptors in the box. Because the AC side is the same across the range, the right choice mostly depends on which cables and devices you carry every day.

The first Pro Chaser 400W Power Inverters listing is the classic layout: two 110V AC sockets and two USB-A ports, with 400W continuous and 800W peak output. The listing suggests it handles 300W to 400W devices such as laptops, breast pumps, DVD players and bottle warmers from the AC side, while the USB ports charge phones, tablets and cameras. It is the most straightforward of the three, with nothing to configure: plug it into the socket, plug your devices in, and the fan looks after itself.
The USB rating is described two ways, as two high-speed 3.1A ports in one place and 4.8A dual USB in another. Most likely 4.8A is the combined figure, but the listing does not say so outright. The specification table also lists six outlets, which does not match the four ports described. The body is cellphone-sized at 4.8 by 3.07 by 1.81 inches and 14.08 ounces. It lists UL, CE and UKCA marks, overload, voltage and overheating protection, and a 12-month warranty.
This version suits families on road trips who mainly charge phones and tablets over USB-A and occasionally plug in a laptop brick. If your laptop charges over USB-C, the second version is a cleaner fit.
Pro Chaser 400W Power Inverters (USB-C PD) Always use the inverter in a cool, dry environment to ensure reliable
Check price on Amazon Our score: 9.6/10
The second Pro Chaser 400W Power Inverters listing, in red, swaps the dual USB-A layout for one USB-A port with 18W Quick Charge and one USB-C port with 65W Power Delivery. For many modern laptops, a 65W USB-C PD port can charge the computer directly, without its AC adapter, which frees up the AC sockets and reduces clutter in the front seat. It also avoids the small efficiency loss of converting to AC and back to DC through a laptop brick.
It has the same 400W continuous and 800W peak ratings, two AC outlets, a 30-inch cord for back-seat reach and protection against short circuits, overloads, low voltage, overvoltage and overheating via a built-in fuse. The listing includes an important note: use only one high-power device at a time, because running the 65W USB-C port together with the AC outlets may exceed the vehicle socket’s limit. It does not state a warranty period, dimensions or weight.
This version suits mobile workers whose laptop, tablet and phone all charge over USB-C. It is the best fit for a car-as-office routine, as long as you respect the one-high-power-device guidance.
Pro Chaser 400W Car Power Inverter Effortlessly connect to power via the cigarette lighter socket charger
Check price on Amazon Our score: 8.0/10
The Pro Chaser 400W Car Power Inverter is marketed for cars, trucks and RVs. It has two AC outlets and two USB ports with a combined 6.2A output, the highest USB-A total quoted in this group. What sets it apart is the included USB-to-USB-C adaptors, which let you plug USB-C cables into the USB-A ports, handy when one passenger has an older phone and another has a newer one.
It keeps the same 400W continuous and 800W peak output, a 30-inch cord, an automatic cooling fan at 113°F and protection against short circuits, overloads, low and high voltage and overheating. It measures 4.85 by 3.1 by 1.81 inches, weighs 0.46 kg and lists UL certification and a 12-month warranty. A few specification entries look unreliable, such as a solar power source and a 70 VA capacity, so rely on the feature descriptions. Adaptors do not turn USB-A into USB-C Power Delivery, so a laptop that needs PD will still need its AC charger.
This version suits RV owners and truck drivers with a mix of older and newer gadgets who want both cable types covered.

Before You Buy
All three listings describe plugging into the cigarette lighter socket, and none mention battery clamps. As general background, most vehicle 12V sockets are fused well below 400W, so in practice a lighter-socket inverter usually delivers far less than its rating. That is why the USB-C listing warns about combining loads. Check your vehicle manual for the socket’s fuse rating before plugging in anything that draws a lot of power. The 800W peak figure is a short surge, not something to run continuously. All three produce a modified sine wave, which suits most chargers and simple devices, but some sensitive electronics run better on a pure sine wave inverter.
The listings do not specify idle power draw, low-voltage shutoff thresholds, or whether the inverter should be unplugged when the engine is off. Running an inverter with the engine off can drain the car battery, especially in older vehicles or in cold weather. If you need to run devices for hours while parked, a portable power station is often the better tool.
FAQ
Can a Pro Chaser 400W inverter charge a laptop?
Yes. All three list laptops among suitable devices via the AC outlets, and the USB-C PD version can charge compatible laptops directly at up to 65W without needing the laptop’s own power brick.
What is the difference between the three Pro Chaser inverters?
The USB ports. One has two USB-A ports, one has USB-A QC 18W plus USB-C PD 65W, and one has two USB-A ports with USB-C adaptors included. The AC outlets, power ratings and cord length are the same.
Is the Pro Chaser inverter pure sine wave?
No. All three listings specify a modified sine wave output, which is common for compact car inverters and works with most chargers.
Can I use it in a truck or RV?
Yes, as long as the vehicle has a 12V socket. The third version is specifically marketed for cars, trucks and RVs.
Does the Pro Chaser inverter have a warranty?
The dual USB-A and adaptor versions list a 12-month warranty. The USB-C PD listing does not state one.
Why does the listing warn against using USB-C and AC together?
Combining the 65W USB-C port with AC loads may exceed the vehicle socket’s limit, so the seller recommends one high-power device at a time.
