The Best AA Battery Chargers That Also Support AAA Batteries of 2020

Demand for rechargeable batteries is growing in the post-coronavirus era, according to research published by Research and Markets— and consumers have many options. There are many types of rechargeable batteries on the market, ranging from super high capacity rechargeables to rechargeables that are tailor made to accommodate the needs of people who frequently use digital cameras, portable stereos and other high drain devices. No matter what kind of rechargeable battery brand you prefer, you’ll need a good quality charger to get the best performance out of it.

The chargers listed below come in a wide variety of shapes and sizes and they all have their unique pros and cons. Some are geared toward world travelers, while others have unique features like audible charge alerts and built-in USB ports. Capacities among AA battery rechargers vary as well. Typical AA chargers can charge four batteries at a time, but some can power up as many as 16 rechargeables at once. Interface features are yet another factor to consider before you make your purchase. More minimalistic chargers rely on simple indicator lights to convey the status of a charge, while others are equipped with full-featured LCD screens.

The fastest AA battery charger

Energizer One Hour Charger

Energizer AA/AAA 1 Hour Charger with 4 AA NiMH Rechargeable Batteries (Charges AA or AAA batteries in 1 hour or less) CH1HRWB-4

As far as we can tell, no other battery charger is faster than Energizer’s One Hour Charger. The industry average for charging time seems to be about four hours among the most popular battery charger brands, but this one is about four times as fast. On the other hand, it’s also twice as expensive. Another unique thing about this charger is that it’s equipped with a speaker. An audible tone lets you know when your batteries are fully charged.

Good

  • Super fast charging. It only takes an hour to complete a charge cycle.
  • Audible charge notifications. When your batteries reach their maximum capacity, an audible tone will let you know that they’re ready to use.
  • Intuitive lights. Indicator lights on the front of the device tell you the status of the charge at a glance.
  • Choose from several different versions and kits. Some of the kits come with batteries, while other versions of the charge can power up multiple battery types.
  • Turns off automatically when the charge is complete. This feature is designed to stop overcharging, which can shorten battery life.

Bad

  • No USB port. You can’t use this charger to power up smartphones and other similar devices.
  • Pricey compared to the competition. The quick charging speed comes at the expense of a higher price point.

In a nutshell

Speed is the key word here. On average, most chargers require four hours to complete a charge cycle. Energizer claims that with this one, all you need is one hour. Additionally, the built-in speaker sounds off when your batteries are totally full. Indicator lights give you a way to check on this if you’re absent when the chime goes off.

In a nutshell

This charger from AmazonBasics has features that are built around portability. No other battery charger we’ve seen can switch between European and American-style power outlets, for example.

EBL 8-Bay Battery Charger

EBL Smart 8 Bay AA AAA Battery Charger for NiMH NiCD Rechargeable Batteries Build-in 2 USB Fast Charging Ports

EBL’s 8-Bay Battery Charger is half the price of an ordinary battery charger, yet it offers double the charging capacity. Standard battery chargers can only power up four batteries at a time, but this one can charge eight simultaneously. Convenient charge status lights let you know when your batteries are ready to use. However, there’s a slight catch: it’s significantly slower than the competition.

Bad

  • Lacks fast charge capabilities. This charger is slow compared to the competition.

In a nutshell

Even though this charger from EBL is inexpensive compared to the competition, it has eight bays and two USB ports. If you plug in two USB devices, you can charge both of them and up to eight batteries simultaneously. Other chargers are much faster, but in terms of raw value EBL’s charger is hard to beat.
