Its narrow beam pattern results in a focused illumination that punches above its weight class to travel as far as rivals with higher lumen counts. These are the rechargeable flashlights we recommend.ĭuring our hands-on testing of the best flashlights, we awarded the Anker Bolder LC40 the accolade of Best Value for its long battery life and consistent lumen output over time. We then narrowed down our pool of expert-picked products based on light output, battery life, and unique features to cover a wide variety of use cases from daily carry to recreational activities to emergency scenarios. We researched seven expert sources such as GearJunkie and Wirecutter, compared more than 50 top-selling models, and used our own testing data here at Popular Mechanics to build a list of the best rechargeable flashlights. If either of these numbers is replaced with an X, it means that the flashlight either offers no protection or has not been tested.
FLASHLIGHT BATTERY GURU FULL
The second number represents the flashlight’s protection from liquids, with 1 indicating something like a vertical rainfall and 8 being full submersion in water, greater than 1 meter, for more than 30 minutes.
The first number indicates solids, with 1 being protection from an object greater than 50mm, like a hand, and 6 indicating that the flashlight is fully impenetrable by grit and dust. You’ll see this as IP followed by two numbers. Lastly, most flashlights come with an Ingress Protection (IP) rating, which is a measurement of the level of solids and liquids that can get into the flashlight. Manufacturers often list claimed battery life for different modes. Low or eco settings, for example, might suffice for smaller jobs and will extend battery life, while higher modes can drain a battery much quicker. Another feature to look for in a rechargeable flashlight is whether or not it offers different power modes. And anything over 5,000 mAh is often used to power stronger lights for hours at a time. The sweet spot for all-day battery life is about 3,000 mAh.
FLASHLIGHT BATTERY GURU PORTABLE
Sub-1,000 mAh batteries can be found on our more portable picks and offer a shorter battery life. Battery capacity is measured in milliamp hours (mAh), which measure electric power over time. With this in mind, take into consideration what you’ll use your flashlight for and how often you think you’ll use it before deciding how much battery capacity you think you’ll need. It’s up to you to keep your rechargeable flashlight juiced.
Just because your flashlight is rechargeable, and you no longer have to worry about stocking the right-size batteries for emergencies, doesn’t guarantee it’s always charged. To light up large, open environments, like a campsite, we recommend a flashlight with a minimum of 1,000 lumens, as LEDs are brightest when first turned on but can dim as they warm up. Still, if you’ll be focusing your rechargeable flashlight’s beam on a concentrated area, such as under the hood of your car, you won’t need as many lumens as you would if you were lighting up a large work area. Meaning, the light with the most lumens may not case the brightest light. Theoretically, the higher the number of lumens, the stronger the light will be, though factors such as reflector shape and lens determine how far and wide that light is cast.
Lumens measure the strength of a bulb’s light, or its overall brightness.
