With so many different options to choose from, it can be difficult to find the right USB charger for your motorbike. We put together this helpful buyer’s guide to make the process even easier for you to find the right charger.

Types of Motorcycle USB Chargers

SAE Connection

Most USB chargers will take advantage of the SAE connection. This is a type of charger that requires an SAE lead and attaches directly to the motorcycle battery.

Many riders will likely install a permanent SAE lead on their bikes. This is an easy install and allows for more flexibility for using chargers and other electronics.

Another benefit to the SAE connection is that it’s safe and designed to prevent short circuits. Installation is as easy as connecting the connectors to the right battery connections and cleaning up the existing wires.

On a new motorcycle you’ll probably have to install the SAE connection on your own. Many used motorcycles will come with the connection already installed.

Direct Connection

Some USB chargers are designed to connect directly to the motorcycle. These can be mounted on the handlebars and plugged directly into the motorcycle battery.

Compared to the SAE connection, a direct connection charger it’s just as easy to install. The main drawback is that it’s less versatile and could cause more drain on the battery.

With a direct connection, always verify that everything is connected properly before starting the bike. This helps to avoid any issues with shorting or overcharging the battery.


The DIN type of USB charger is designed to fit into any existing power ports on your bike. For example, some motorcycles come with a 12V socket and this is where the DIN charger can be used.

The DIN setup is able to handle a larger electrical current from the battery. This usually results in better performance overall and a more powerful current for faster charging.

Compared to the other styles, a DIN connection is safe and has better stability under vibration. It’s also the easiest to use, especially if your motorcycle already comes equipped with the 12V outlet.

Benefits of Motorcycle USB Chargers

There are a number of benefits to using a USB charger on your motorcycle. Whether you’re motorcycle commuting, going on long trips, or just riding around, it’s great to be able to keep your devices charged.


With a USB charger on your bike, you won’t have to look for power outlets or somewhere to charge your phone. Everything can be connected on your motorcycle and charged while you’re riding.

This way you don’t have to worry about getting stranded because your phone ran out of battery or your motorcycle GPS died. Instead, everything is charged and ready for you to use it.

Compact Design

Compared to wall charger, USB chargers take advantage of a streamlined, compact design. They don’t take up as much space and can be easily installed on your motorcycle.

Even the smallest chargers can be used to charge up to two different devices at a time. Whether you mount in on your handlebars or stash it under the seat, these chargers rarely get in the way.

Easy to Install

If you’re someone that rides a lot, there’s no reason why you shouldn’t have a USB charger. Keeping your phone charged means you can always easily take photos, refer to your navigation, change music, or just keep in touch with people at home.

Installation is simple and even the most novice garage mechanic would be able to figure it out. Installing your own USB charger can also help build your confidence when it comes to working on your bike.

Pricing for Motorcycle USB Chargers

Depending on your budget, there are different options available for a wide range of prices.

Under $20

At this price point you’re looking at basic chargers that don’t come with any extra features. However, they’re more than capable of keeping your devices charged for when you need them.

Don’t expect to find features such as power switches and locking mechanisms with chargers under $20. Thankfully, there are still some great options that are reliable, durable, and suitable for riding with.

Over $20

At this price point you’ll be looking at some of the better quality chargers. These will come with more features, better mounting options, and different installation options.

Chargers in this price range will be more versatile and include a wider range of different features. You’ll also be able to charge more than one device and take advantage of a better output.

Important Features


Safety is one of the most important things to consider when choosing a motorcycle USB charger. This is where it might be worth spending a few extra dollars to buy a better quality model with safety features.

Most newly-designed chargers are equipped with overcurrent protection. Unfortunately, some of them still might be susceptible to short circuits and other types of electrical damage.

Check the safety features beforehand and look for any additional features you’re interested in. This could include weather resistance, volt limits, and a more durable design.

These safety features are important if you’re planning to spend a lot of time riding outdoors in different weather elements and conditions. It’s important to protect your device, and the charging unit itself, from dirt, dust, water, moisture, and other harmful elements.


Most riders likely want to mount the charger to the handlebars. Alternatively, there are other mounting options depending on your preferences.

For example, some devices can be installed in places that are less accessible and exposed to the elements. Under the seat or on the side of the motorcycle attached to the frame are other popular choices.

Think about which setup works best for your bike, riding style, and personal preferences. For convenience, handlebar mounting is the best, while under-seat or frame mounting is ideal for riding in rough conditions.

Charging Speed

Not every charger is designed the same way. They aren’t all compatible with the same devices and compatibility depends on the technical specifications.

Connecting a phone that requires a fast charger with a slow USB adapter will result in a slower charge. It can even be dangerous connecting two units with different technical specifications which could lead to short circuits or electrical problems.

Number of Ports

Depending on the charger, there will be either one or two USB ports. This is something to consider before making a purchase.

If you need a charger that can charge more than one device at a time, you’ll want to go with two USB ports. Otherwise, for keeping your smartphone charged, one port is enough.


Always check whether a charger is compatible with your motorcycle and current battery setup. Take a look at the different types of chargers mentioned above for a comparison of the different setups.

Not all chargers are designed the same. It’s important to use one that’s compatible with your motorcycle battery and that can be easily connected.

You may need to buy all of the connection wires if your battery isn’t set up for it already. Alternatively, an adapter might be all that you need.

Power Switch

The power switch feature is found on the higher-priced, better quality chargers. This allows you to turn the charger off when it’s not being used.

The power switch is a useful feature that helps to make it safer. Many of the newer models come equipped with the switch, although some of them will stay on all the time.

Helpful Tips

Most riders will use the USB charger to keep their smartphones and GPS devices charged. You can also use the charger for charging your motorcycle camera batteries, tablet, and other motorcycle accessories that you’re using.

Keep an eye out for motorcycle USB chargers that come with weather protection. This would be a cover that provides additional protection from moisture, dust, and dirt. It’s great to have this feature if you’re riding daily in various weather conditions.

Alternatively, be careful about using your USB charger if it doesn’t have any weather protection. It’s possible for the internal components to get soaked in water and this could lead to short circuits that could damage your motorcycle battery.

Best USB Charger For Motorcycles FAQ

Do USB Chargers Drain the Battery?

Even with nothing connected, it’s likely that the USB charger will drain a small amount of current. Thankfully, this isn’t enough to fully drain the battery if you’re riding regularly.

Don’t forget to disconnect any devices if you’ll be away from the bike for more than a few minutes. It’s also a good idea to disconnect the charger when you’re putting away your motorcycle for the winter season.

What Are the Installation Options for Motorcycle USB Chargers?

In this post we covered the three main USB charger connection options. These would be a direct connection, DIN, or SAE connection to the battery.

Each of these connections is easy to install and compatible with every type of motorcycle battery. Refer to the included instructions or check on YouTube if you’re having any difficulties with the installation.

As for which option is the best, this depends on the power options included on your motorcycle. It also depends on your personal preferences and which style would work best for your type of riding.

Are Motorcycle USB Chargers Waterproof?

Some models are waterproof and we recommend going with a water-resistant charger. Not every charger offers the same level of protection.
