Best Power Inverter For Car in 2018 [Reviews & Comparison]

BEST POWER INVERTER FOR CAR

At the most basic level, AC power is the current that you get from your plug sockets at home, and DC power is used by batteries.

Therefore, car batteries run on DC power, whereas most consumer electronics use AC power.

As a result, if you want to use these devices on the go, then you'll need something called a 'car power inverter,' so that the DC current can be changed to AC, and thus be compatible with your electronics.

Our ​Power Inverter For Car Reviews

1. ​ENERGIZER EN500

Energizer 12V 900 WATT POWER INVERTER

The Energizer EN500 is a top-tier car power converter that is designed for use out of the vehicle. With its 3-foot battery cables, it’s better suited to hooking up to a stationary vehicle at a camp ground, for example, as opposed to charging on the go. It is moderately pricey, although that’s well justified.

Energizer 12V 900 WATT POWER INVERTER

Features:

  • ​Cord length: 3-foot battery cables
  • ​USB nº: 2 USB ports, 2 AC outlets
  • ​Output: 900-watts
  • arrow-circle-right
    ​Power inverter from DC 12V to AC 900W
  • arrow-circle-right
    ​Warranty: Unspecified

​Product Highlight :

This power inverter from Energizer is an extremely heavy-duty unit that connects directly to a 12V DC battery to provide power to a wide range of electronics, including TVs, gaming consoles, power tools, smartphones and so on. Unlike cheaper models, it includes an LCD display. It's got 2 USB ports and 2 AC outlets, thermal cooling and thermal shutdown, and a range of other safety features.

What's to like about ​it :

It’s easy to see where the price tag is justified. This power inverter features an LCD for displaying input and output power, as well as battery level, which is an incredibly useful information to have, save for running your car flat. The product comes with 3-foot battery cables and has AC sockets spaced well apart, meaning devices with larger plug sockets won’t get in each other’s way.

What's not to like about ​it :

The negatives aren’t a big deal in terms of value for money, but they’re worth being aware of. Firstly, this is the most expensive product we’ve reviewed, at around 4x the cost of some alternatives. There’s also no cigarette lighter connector, meaning you’ll have to use the included battery cables to hook this up; that is a more dangerous task than simply using an in-car outlet.

PROS

  • Built-in LCD display
  • ​Includes 3-foot battery cable
  • ​Plug sockets are spaced well apart

CONS

  • ​More dangerous to use
  • ​No cigarette lighter port connector
  • ​The most expensive model on our list

​2. ​COBRA CPI 200CH

Cobra Electronics - DC Outlet Power Inverter

The CPI 200 CH is a power inverter designed to fit into the cup holder in your vehicle, converting your 12V cigarette plug into an AC outlet. It’ll charge a single AC and USB, enough for a driver or passenger to charge their electrical devices, though it has no extra space built in for other passenger items.

Cobra Electronics - DC Outlet Power Inverter

Features:

  • ​Cord length: Short
  • USB nº: 1 USB port, 1 AC outlet
  • ​Output: 200W continuous, 400W surge
  • arrow-circle-right
    ​Power inverter from DC 12V to AC 200-400
  • arrow-circle-right
    ​Warranty: 30-day warranty

What's to like about ​it :

With a cupholder-based design, this inverter can ride up front with you, giving you easy access to your charging ports. There’s a very basic design for controlling the power, too. Picking up one of these won’t break the bank, as it’s one of the cheapest in-car inverters we’ve looked at.

What's not to like about ​it :

With this unit, you only get a single type of each port, allowing one smartphone to be charged alongside one other household electrical device. What’s more, the power cord is very short, though this might not be such an issue when the product is placed in a cupholder in the front cabin. The warranty is unusually short, too.

PROS

  • ​Convenient cup holder design
  • ​Simple user interface
  • ​One of the more inexpensive models

CONS

  • ​30-day warranty is very short
  • ​Only a single USB and AC port
  • ​Power cord isn’t very long

​3. ​BESTEK MRI3011BU

BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter

The BESTEK Advantage comes from a brand that is widely regarded in America as a leading provider of power inverter products. This unit is very compact, weighing in at 1.16 pound, and has 2 USB ports and 2 AC outlets

BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter

Features:

  • ​Cord length: 24-inch cord
  • ​USB nº: 2 USB ports, 2 AC outlets
  • ​Output: 300W continuous, 700W instantaneous
  • arrow-circle-right
    ​Power inverter from DC 12V to AC 110V
  • arrow-circle-right
    ​Warranty: 18-month warranty

​Product Highlight :

The BESTEK Advantage incorporates a lightweight, durable design, with fast charging for 2 USB devices and 2 AC-powered simultaneously. It has built-in multi-protection, with a 40-amp fuse protecting your devices against short circuits. An integrated cooling fan aids to reduce the build-up of heat that could lead to shortages.

What's to like about ​it :

Overall, this inverter is no bigger than a leading brand smartphone, making it easy to tuck away within your vehicle. The unit also has some safety features, including built-in fuse protection, which helps to protect your devices in case of a short circuit. Finally, there’s an 18-month warranty included, which is non-limited, offering further peace of mind.

What's not to like about ​it :

Unlike some models like the Duracell power inverter that we’ve looked at (below), this product has a very industrial-looking design, which doesn’t blend well with the interior of most vehicles. The included cord also falls short compared to many alternatives. Finally, the USB plugs remain powered-on unless the unit is disconnected completely, which could lead to a drain on your car battery.

PROS

  • ​Non-limited 18-month warranty
  • ​No larger than an Apple smartphone
  • ​Built-in fuse protection for your device

CONS

  • ​Industrial design
  • ​Has a relatively short cord
  • USB ports always remain powered-on

​4. DURACELL POCKET INVERTER 175


Duracell DRINVPS175 Black 175 Watt Portable Power Inverter

The Duracell Pocket Inverter 175 is a premium brand product with a small footprint, available on the market since mid-2013. It’s a lot smaller than some other inverter units, though this can be beneficial from a logistical point of view.

Duracell DRINVPS175 Black 175 Watt Portable Power Inverter

Features:

  • ​Cord length: 36-inch power cord
  • ​USB nº: 2 USB ports, 2 AC outlets
  • ​Output: 130W continuous, 150W peak. 5V / 2.1A (USB)
  • arrow-circle-right
    ​Power inverter from 11-15V DC to 115V AC
  • arrow-circle-right
    ​Warranty: 3-year limited warranty

​Product Highlight :

This Duracell 150-watt inverter allows the use of AC and USB-powered devices inside the car when connected to the DC outlet. It has a slim design with 2 front-mounted USB ports and 2 front-mounted AC outlets. There are built-in safety features, too, including short circuit and AC input overload protection, as well as DC input over/under voltage guarding. There is also built-in temperature protection.

What's to like about ​it :

Due to its small size, this Duracell inverter is extremely lightweight. This means that it can easily be mounted in a variety of locations in smaller cars, where space is a concern. What’s more, the front-mounted sockets are easily accessible, making it even easier to position and mount the inverter.

What's not to like about ​it :

This unit is lacking a power switch, meaning that the only way to turn it off is to disconnect it entirely from the source. It is also expensive for its size; there are similar alternatives for less price. Finally, Duracell products, though well known, are not always the best performing and more durable products around.

PROS

  • ​Lightweight design
  • ​Can easily be mounted
  • ​Easily accessible front-mounted plugs

CONS

  • ​Lack of a power switch
  • ​Expensive for a small model
  • ​Duracell products not always durable

​5. ​Foval Power Inverter 300W DC

Foval Power Inverter 300W DC 12V to 110V AC Converter with 4.8A Dual USB Car Charger

The Foval Power Inverter is a 300W DC 12V to 110V AC Converter that comes in at the budget-range of the market. It has enjoyed generally favorable feedback since its release in mid-2017.

Foval Power Inverter 300W DC 12V to 110V AC Converter with 4.8A Dual USB Car Charger

Features:

  • ​Cord length: 30-inch cable
  • ​USB nº: 2 USB ports, 2 AC outlets
  • ​Output: Max 4.8A
  • arrow-circle-right
    ​Power inverter from 12V DC to 110V AC
  • arrow-circle-right
    ​Warranty: Unspecified

​Product Highlight :

This is a premium 300-watt car power inverter that has 2 USB ports for charging smart devices, as well as 2 AC outlets for laptops and other home electronics, such as game consoles or DVD players. The unit has FCC authentication and is super-compact and lightweight. A durable metal casing provides increased durability and protection against bumps and bangs.

What's to like about ​it :

This inverter contains a cooling fan to help prevent overheating, and indeed it doesn’t heat up excessively during operation. What’s more, it can support a wide range of devices for what is a very reasonable price tag. Laptops, smartphones, tablets and so on, can all be charged at once.

What's not to like about ​it :

The unit could do with being larger, as the outlets are so close together that bigger plugs struggle to fit alongside one another. It would also be useful to have a longer cord for the charger. Finally, the directions leave a lot to be desired; the translation is poor and difficult to understand.

PROS

  • ​Doesn’t heat up during use
  • ​Cooling fan helps prevent overheating
  • ​Can support wide array of devices simultaneously

CONS

  • Outlets too close together
  • ​Directions aren’t translated well
  • ​Ideally, length of cord could be longer

FINAL VERDICT

Despite it being the priciest option on the list, our choice out of these 5 popular in-car power inverters is the ENERGIZER EN500. With the Energizer brand, you know that you’re getting a trusted household name, as well as one that is bound to adhere to safety standards. Though it can’t be used for in-car charging, it’s the perfect solution when you need power at a campsite or while stationary.
