Simple Charger

Representing the most basic technology, a simple battery charger uses electrical parts to take power from an external source and relay it to the batteries in the ports. Because it has such a straightforward design, most of these chargers have only four ports. Often, the charger will be able to power different battery sizes and types. Though they are called simple, this type does have overcharge protection and overheating safeguards in most models. 

Intelligent Charger

Perhaps the most common type of AAA battery charger, the intelligent namesake results from the advanced technology used during the charging process. Operating on the same concept as a simple charger, an intelligent type includes three tiers of power supply. By judging how full the battery is, the charger reduces the flow of electricity to help it get the most charge possible. This trickle flow fills the battery to the maximum extent while still protecting against surges and overheating. 

Top Brands


Opening its doors in 1896 in Missouri, Energizer has become one of the best-known names in the battery industry. Offering all types of dry cell batteries and corresponding accessories, this business is known internationally for its high-quality products. A top offering from this brand is the Energizer AAA Battery Charger.


After its founding in 1918 in Osaka, Japan, Panasonic took the international electronics industry by storm. It has grown into a massive name globally with its diverse supply of technology. With everything from televisions to batteries, this company remains popular over a century after opening. One of its best-favored selections is the Panasonic Advanced Eneloop Battery Charger.


With roots in California, Tenergy opened its doors in 2004 and began manufacturing high-end electrical supplies. It has a wide range of products including batteries and chargers of all shapes and sizes. Among the most popular offerings from this brand is the Powerowl AAA Battery Charger.

AAA Battery Charger Pricing

  • Under $20: In this price range, you are likely to find chargers with between four and eight ports. You can get both simple and intelligent chargers within this budget. 
  • $20 and up: AAA battery chargers in this price range tend to have more ports (up to 16) and are more likely to be of the intelligent charger type. 

Key Features


This feature involves the place where you put the battery being charged. The number of ports will vary, with most having between four and 16 independent bays. The ports must be wired parallel to one another to ensure separate charging. This is the part that draws in power and, through the anode and cathode, supply it to the battery. The port must hold the battery in place to ensure quick charging. 

Power Source

This part of the battery charger is the component that takes in power from an external source. Depending on the size and design of the charger, the source will differ. Some use a USB connection and take power from your laptop. Others incorporate a 12-volt adapter and plug it into your vehicle. The most common is for the charger to get powered through a wall outlet. In most cases, this also results in the quickest recharge.


This feature refers to the measures in place that will prevent damage to both the charger and our batteries. It also includes the part that adjusts the flow rate and optimizes the amount of charge you get. To be durable, the charger must have safeguards against power surges, overcharging, and overheating. This includes suitable ventilation to prevent the charger (and batteries) from getting too hot. It also keeps the internal circuitry working for longer. 

Other Considerations

  • Size: When you go to choose your AAA battery charger, you will want to spare a thought for how it will fit in your area. Some chargers are compact and take up next to no room. Others are bulky and require a dedicated space. While smaller chargers have fewer ports, if you are dealing with spatial limitations, it may be better to opt for something more compact. 
  • Indicators: If you plan on getting a charger for eco-friendliness, it helps to remove the batteries as soon as they are full. Most chargers incorporate either an LED light or an LCD screen to show how far along the charge is. Consider that LCDs draw in more power, though tend to be more accurate than LED lights. 
  • Design: Next, think about the actual design of the charger. Take a look at the different colors available and the different styles. There are rectangular options that plug into your wall and round chargers that lay flat on your desk. Give thought to the ventilation requirements of the charger to make sure that there is enough airflow where you plan to place it. 
  • Maintenance: Take a moment to consider how much upkeep the charger will require. Does it have a cover to prevent dust from getting in or will you need to wipe it down regularly? Think about any steps you are going to need to take to keep the charger in working condition and how difficult the upkeep will be. Chargers are meant for convenience, so lower maintenance needs are important criteria. 
  • Durability: Finally, consider how long-lasting the charger will be. Those with more ports tend to wear out quicker than smaller models. They are also more vulnerable to impact damage. Chargers made out of heat-resistant polymers that are resistant to scratches will generally perform better over the long term.
