There are “rechargeable” flashlights on the market that are really just flashlights with rechargeable Li-Ion batteries like 10400, 14500, 16340, and 18650, but they require the batteries to be removed and charged with an external charger. Another option are flashlights that you can put Ni-mh batteries in, but you can not use alkaline batteries.
In this article, we will only cover flashlights that are internally rechargeable or ones that have the ability to charge without removing batteries much like a cell phone. These types of lights add so much convenience to having a light with you. Luckily nowadays you can get internally rechargeable flashlights in most styles and types, from EDC lights to tactical you are covered.
The biggest achilies heal of internally rechargeable flashlights is the charging connection and how they have setup the protection against water.
Most rechargeable flashlights do not have custom battery types. They use Lithium-Ion batteries like those listed above, and they have built-in chargers. Rechargeable flashlights can be slightly more expensive than other flashlight types, but you do not have to purchase a separate charger for your batteries.
Some cheaper rechargeable flashlights do not have internal smart chargers, so they can overcharge the batteries, which can destroy them. Some lights plug into the wall, some have cell phone chargers and use USB, and some have special charging stations.
Most modern rechargeable flashlights use LED (Light Emitting Diode) technology instead of older types of bulbs. LEDs take only a fraction of the amount of power, are lighter, have much longer run times, and are shock resistant. They also allow you to get lights with different color beams depending on what you are trying to do.
Rechargeable flashlight LEDs allow almost every aspect of the rechargeable light to be better.
Types of Batteries: Removable and Non-removeable
Before we get to the rechargeable flashlight reviews, we have to cover batteries. The only flashlights that we are covering here are rechargeable LED flashlights with internal chargers. Within the group of internally charging lights, you can get flashlights that have removable batteries or flashlights with built-in batteries that can not be removed.
For smaller flashlights, we think the best LED rechargeable flashlights give the option to remove the batteries, so we can charge them externally if we want and we can have multiple sets as backups.
- Replacement batteries are cheaper
- Multiple sets means less waiting to recharge
- A battery designed specifically for that flashlight
- Less moving parts
- Can reduce size

Rechargeable Flashlight FAQs
What is the highest lumen rechargeable flashlight?
Right now in 2021 the highest lumen rechargeable flashlight is the Imalent MS18 which has a top output of 100,000 Lumens.
What’s the service life of a rechargeable flashlight? How long do they last?
When talking about the service life of a flashlight there are two parts of the light that could go out. The LED and the battery. LEDs are labeled as good for 50,000 hours, this is 5 years and 255 days of continuous use. For Li-ion batteries, they are said to be able to handle 300 to 500 charge cycles. So if you recharge every week it will be good for over 5 and a half years.
What rechargeable flashlight do police and military use?
Most police officers wil have three different lights. They will have a “duty” light that is bigger and usually has the ability to plug into the car, the most popular choice for police departments right now is the Streamlight Stinger series. The second light will be a back-up or smaller light and this is usually up to the officer. Last they will have a pistol light on the end of their handgun.

The best way is to use the brightness level that you need instead of always running on turbo. Next, we would recommend having the charging cable with you or carrying a power bank.

As with most eCommerce products, Amazon is a good choice but we like dealing with manufacturers direct or with specialized flashlight online stores. If we can put more money in the hands of small businesses or direct to manufacturers we try.
