Buyer’s Guide


Here are some essential factors to consider before deciding which motorcycle USB charger to buy. 

Connector Type: SAE

You might have noticed that all the products in this review offer SAE connectors. While you may have heard about other battery connectors (like DIN), SAE connectors are more commonly used in the United States. 

You’ll find two color-coded ring terminals on the SAE cable end that are connected to your battery, making it easy to attach the connector to the positive and negative nodes of your bike battery.

SAE cables are safer and less prone to short circuits, plus you can connect them to any bike. 

Water/weatherproof 

Given the nature of bike rides, it is important to consider whether a USB charger will survive the weather. If you are prone to experiencing rain or dust, pick a USB charger with a weather-resistant or waterproof cap. 

While the cap/cover protects your charger from sudden rain, remember that the chargers are still electric devices not specifically manufactured to be used in the rain. 

Power Drain

Connecting a USB charger drains power from your motorcycle battery, especially with chargers that feature LED lights to indicate that they’re turned on.

While the drain is not huge it can cause problems. 

The main issue arises when your motorcycle is parked or not running for an extended period (weeks or months), and the charger is connected.

This can drain and waste a lot of power from your motorcycle battery because USB chargers are connected directly to the battery, which keeps the LED light on regardless of the status of your ignition. 

You can consider two things: buy a USB charger with an on/off switch for the LED or remember to remove your charger from the battery when you intend to leave your bike parked for an extended time.

Installation 

USB chargers specifically made for motorcycles are not that complicated and just need to be connected to the battery through SAE connectors. Products that include SAE cables will save you the hassle of buying them separately. 

Amperage

SAE connectors are versatile and are manufactured for various power levels. Typically, mobile phone chargers deliver a current of 2.1 Amp—remember that phones are designed to draw only as much current as they need, regardless of the charger. 

However, if your phone has a higher drawing capacity, it will charge faster when connected to a higher power charger.

If charging speed matters to you, go for chargers with higher amperage. To reiterate, if your phone has a lower drawing capacity, a 3.1 Amp charger will not damage it; your phone will take as much as it needs. 

Cable\wire length

The longer the wire, the better. Depending on your bike, some cable lengths might make turning the handlebars difficult.

Final Thoughts 

The YONHAN Motorcycle USB Charger is the clear winner because of its exceptional features, especially the switch. The MOTOPOWER Motorcycle USB Charger Kit is better for those wanting a high power output.
