USB Adapter Tips for Use in a Truck

Why would a trucker need a USB adapter in his or her truck?

USB Adapter or Universal Portable Travel Wall ChargerIn the 21st century, more and more professional truck drivers have cell phones and Smartphones that need to be kept charged.

Is this just a luxury?

Having a cell phone is not a luxury for lots of today’s professional truck drivers.

Many truckers are using their phones to do their trucking business, including getting loads. (1,2)

On this page we will give an overview and some specifics regarding adapting a power outlet for a USB plug.

Cell Phone Chargers and Devices with USB Plugs

When we purchased our Samsung Stratosphere Smartphones, each came with its own AC power charger.

We purchased a separate car charger (for charging via DC power).

Over time, the DC charger and one of the AC chargers died (or otherwise stopped working).

So, we needed to replace them.

The only difference appears to be the configuration of the adapter.

Will “any” AC-to-USB adapter work to allow charging through a cord with a USB plug from an AC power source?

Check all of the specifications first.

Besides phone charger cords, a number of GPS receivers are also configured with a USB plug or end, too.

Why This Matters to Truckers

Until commercial motor vehicles have power panels like this one (image) or this one (image and Instructable), truckers will have to provide their own adapters to charge electronic devices that come with cords wired with USB plugs.

We have found this variety of USB adapters on the market in the USA:

  • AC power to USB plug-in;
  • DC power to USB plug-in; and
  • DC power to both AC plug-in and USB plug-in (as inverters).

The most common type of power outlet we’ve seen in trucks is DC (direct current).

We previously covered inverting DC power to AC power with an appropriately sized inverter.

USB Ports on Inverters

Models of the two types of inverters we have used in our trucks both came with USB ports.

Depending on where this device is installed in one’s truck, a USB extension cord may be required to keep the device within easy reach of the driver.

On the same panel is an AC outlet, the one that we usually used in our trucks.

During our June 2013 business trip, we utilized this inverter for powering two devices at the same time:
– an AC device (laptop computer) and
– cell phone via charger without the AC adapter on the end.

Other Types of Adapters

What types of adapters are available at truck stops or online?

Vicki found two types of USB adapters at a chain truck stop in June 2013:

The USB adapter shown here operates off DC power.

We have found it best for DC power to be inverted to AC power.

For your convenience, here are links to various types of products:

  • 12-volt inverters
  • 12-volt USB Adapters
  • USB Adapters

truck drivers money saving tip iconMoney saving tip: Although USB plugs and ports may be standard, adapters may vary.

If one is inverting power from a DC source using an adapter, be sure to note whether or not the device includes a fuse that can be replaced.

(We have noted fuse failure in the cords of thermoelectric coolers we have used as well as the device to protect our inverter.)

Check for a warranty, if one is available.

If adapters don’t even come in packages, chances are good that they won’t have a warranty.

Does this say something about its quality?

Is there any disclaimer associated with use of your USB adapter?

What happens if you encounter a power surge that affects your electronics?

Your use of an adapter means that you will be responsible if something happens to the device you plug into it when it is plugged into your power source.

If your cell phone costs $300, should you use a “cheapo” adapter to power it?

Or is the cost of the adapter a moot point?

If you have the option to do so, research different adapters to see which ones are truly quality products that will last.

As we describe on our goal setting page, a more expensive but better quality product may wind up being a better value in the long run.

Are you planning to buy your product from a truck stop?

Note the return policy. Keep your receipt.

If you need to return it, do so before the return deadline.
