A windshield head-up display, or HUD, is a beautiful thing. Capable of displaying navigational guidance, vehicle speed, and other information on the lower part of the windshield and in the driver’s line of sight, HUD systems have become increasingly common on new cars since their first appearance a couple of decades ago.
More recently, a handful of aftermarket suppliers and startups have gotten on the bandwagon, offering devices that pair with a smartphone via Bluetooth to provide similar functionality, even if these devices lack the seamless integration of a factory system.
Even if your car is equipped with a built-in power port or two, it may not have enough outlets to support all the electronic devices and habits of you and yours, or said ports may be inconveniently located or accessed. Maybe you want a configuration your car doesn’t have, like a 120V outlet to power a laptop or portable DVD player. Or maybe whatever ports your car has just haven’t been quite right since that last Big Gulp incident.
If any of these scenarios is the case, a power inverter can be the solution. Depending on the make and model you choose, an inverter can give you the versatility to power several devices at once, juice up your laptop or other electronic device, or provide more power and quicker charging than built-in ports in your car. And with prices starting at less than $50, inverters are affordable enough to make sense for almost any budget.
Safety experts generally agree that shutting off your phone altogether while behind the wheel is the safest way to travel, but the reality is that just isn’t going to happen for many drivers. In spite of thousands of deaths and close to a half million injuries chalked up to distracted driving every year, we are a society largely addicted to our phones.
But experts also agree going hands free is a safer option than handling a phone on the go, and most newer vehicles now have Bluetooth so drivers can keep their eyes on the road and use voice commands to make and receive calls. While arguably still distracting, hands-free calls are a better idea than punching keys at highway speeds, when a car travels the length of a football field in about five seconds — coincidentally, the average length of time it takes to read or send a text message.
For owners of vehicles without built-in Bluetooth, there are all kinds of aftermarket solutions available, from small units with a microphone and speaker that clip to a sun visor and cost as little as $20, to replacement head units that will set you back hundreds of dollars or more. For the purposes of this exercise, we looked at the former for their ease of installation and low cost.
