What to Look For in Portable Battery Chargers

When you’re getting ready to buy a portable battery charger there are a few aspects to look for. This will help ensure that you are getting the right one for your needs and vehicle.


One of the first things to look at is amperage. This will determine how long it takes to charge the battery. Amperage is the term for the power output level produced by the charger when it’s connected to the battery. Higher amperages result in faster charging times. For example, Genius 1 is a 1-amp battery charger.


A primary advantage of a portable charger is its compact size. This is especially true if you’re using it with ATVs and other small vehicles. Smaller chargers are also easier to handle. Along with size, the charger should also be lightweight. The point of having a portable charger is convenience. It shouldn’t be difficult to carry or maneuver into position. If you’re wondering about the NOCO portable charger, it measures 3.4 x 4 x 6.7 inches and weighs 1.08 lbs.

Safety Features

A battery charger needs to come with safety features, and Genius 1 has plenty. This includes over current and over voltage protection. It will also protect against overloads and reverse polarity errors. All of which can damage your car battery.


You will need to know the battery’s voltage before buying a charger. The charger must be compatible with the voltage to safely work. In general, vehicle batteries are either 6 or 12-volt. Genius 1 is compatible with both voltages.

Maintenance Mode

This is a helpful feature to have if you plan on traveling long distances. Maintenance Mode is typically found on smart chargers and its purpose is simple. It slowly charges and maintains the battery, which results in a longer lifespan. A full charge will last longer and this is always a plus.

Engine Restart

A convenient feature to have is a fast starter option. This allows the charger, once connected, to give the vehicle battery a quick jolt. It is a quick and easy way to jump-start a battery after it dies.


The last thing you want is for the charger to stop working the same time your vehicle’s battery dies. To avoid this annoying situation, choose a portable charger that is designed for durability. Along with sturdy and lightweight construction, look for an IP60 rating. This ensures that the product is water and dustproof.

LED Display

Having an LED display might not seem that important until you try and use the battery charger at night. The bright lights will make the display easy to read so you can constantly monitor the battery’s progress.

You can find these aspects and more in the NOCO Genius1 1-Amp Fully-Automatic Smart Charger.
