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. 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. Luckily now days you can get internally rechargeable flashlights in most styles and types, from EDC lights to tactical you are covered.
Most rechargeable flashlights do not have custom battery types. They use Li-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. 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
