Storm Preppers - Battery Powered Flashlights

Battery-powered flashlights are useful tools for emergency kits, first aid kits, vehicle kits and everyday use. These flashlights are powered by different types of batteries which make them convenient and practical for various situations. A battery-powered flashlight can be a reliable tool during hurricane season, especially if you must navigate through a power outage.

Although it is not possible to research and test all the battery-powered flashlights on the market, consumers must try to find the ones that offer the best combination of brightness, durability, and battery life. Whether you’re preparing for hurricane season, extreme weather or just looking for a reliable flashlight for everyday use, this guide will help you choose the right one for your needs.

Best Battery-Powered Flashlights

When purchasing a battery-powered flashlight, it is important to consider the type of battery it uses. Different flashlights may require a specific type of battery, which may be alkaline, lithium, or nickel-metal hydride. Additionally, some flashlights use disposable batteries, while others use rechargeable batteries. Disposable batteries are convenient because they can be easily replaced and easy to find in stores. But, they can also be harmful to the environment and wasteful, because they cannot be reused. Rechargeable batteries, on the other hand, are more environmentally friendly and cost-effective in the long run.

Another factor to consider when purchasing a battery powered flashlight is its brightness. The type of battery for the light can affect the how bright the light gets and its overall lifespan. Additionally, the durability of the light, which is directly related to battery and how long is lasts when in use is another essential factor to consider.

Here are five of the top battery-powered flashlights that you should consider when shopping around:

  • Battery: The GearLight requires several AA batteries, which can add up in cost over time.

BrightnessLumens, brightness settings and battery life
Size and WeightPortability and ease of use
Water ResistanceLevel of resistance
MaterialSturdiness and durability
FocusAdjustable vs. nonadjustable

Battery Type

Consider the type of battery the flashlight uses. Most flashlights use either disposable or rechargeable batteries. While disposable batteries are convenient, they can be expensive to replace over time. Rechargeable batteries, on the other hand, can be more cost-effective in the long run but require access to a power source to recharge.


The brightness of a flashlight is measured in lumens. Higher lumens mean brighter light, but also typically mean a shorter battery life. Choose a flashlight with a brightness level that meets your needs.

Size and Weight

The size and weight of a flashlight can impact its portability and ease of use. A larger, heavier flashlight may be more durable and provide more light, but may not be as convenient to carry around.

Water Resistance

The water resistance of a flashlight can impact its use in certain conditions. If you plan to use the flashlight in wet conditions, look for a product with a high water resistance rating.

Additional Features

Some flashlights come with additional features, such as adjustable focus or multiple brightness settings. Assess these features and decide if they would be useful for your intended use.
