I get it!  Looking for a new flashlight is tough. So what is the best AAA battery flashlight or penlight today?

There are LOADS to choose from. Well, we’ve made it easy in this post, so get settled in, pour yourself a drink, and let’s get started.

Whether you are hiking through the hills or if you are preparing for emergencies, a flashlight is a useful tool for many occasions.

To have it handy when you might need it most, it is vital to have a practically-sized flashlight that you can carry with you. Small AAA-battery flashlights are super convenient to take with you in your pocket or backpack.

When considering which AAA flashlight would be best suited to your needs, keep several factors in mind. Naturally, the portability of the flashlight is essential. This includes its overall weight and size.

BEAR IN MIND: While AAA battery flashlights are usually conveniently small, there are some larger ones.

The durability of the flashlight is also essential. This is especially true if you are planning on using it outdoors or potentially inclement conditions.

While the overall power of a AAA flashlight is usually limited, one should also look at the luminosity of the light and the maximum beam range.

Some real gems have an incredibly powerful light-producing capacity that will make you wonder how a AAA battery could generate such power.

Finally, one should consider any extra features that the flashlight offers, including clips, different types of toggle switches, and emergency radio functions. You never know when these “bonus features” might come in handy.
