Choosing the right battery charger can be hard. This battery charger buying guide will help you. The POWEROWL 8 Bay charger is our top pick. It has a smart chip control that stops charging when the batteries are full. For a lower cost option, consider the Amazon Basics charger. It charges just two or four AA or AAA batteries at a time, meaning you lose some charging capacity.
The main tradeoff is between charging capacity and speed. The POWEROWL charger can handle up to eight batteries at once. It offers smart charging features, while the Amazon Basics model is more limited. The rest of this page gives you more details about each option.
