Best rechargeable flashlights

What makes the best rechargeable flashlights?

The world seems to be split into two groups: those who think rechargeable flashlights are a good idea and those who think they’re the worst idea ever!

As ever, there’s a kernel of truth in both opinions, so the simplest thing is to run through the list of pros and cons to discover whether the benefits outweigh the compromises for you.


  • In the long run, rechargeables are cheaper than disposable batteries. And the more you use your flashlight, the more you’ll save.
  • They’re environmentally-friendlier, in that you’re not throwing out one-use batteries.
  • They can have high-capacity batteries individually-tailored for the size and style of the flashlight.
  • You don’t have to have a drawer full of spare batteries.


  • The upfront cost is higher.
  • Rechargeable batteries lose their charge faster than alkalines. If you use your flashlight infrequently, you’ll need to check that it’s still topped up.
  • Charge times can be slow, depending on the method user.
  • For flashlights with sealed-in batteries, once the power has been drained the flashlight is useless until you charge it again. For this reason, many people prefer replaceable rechargeable batteries which you can swap out and charge separately.

The ideal use-case for a rechargeable flashlight is something like a security guard. Here, the user can charge up their light between shifts, take it out on their rounds and know that it’ll be charged and ready to go. Then, at the end of the shift, they put it back on charge again.

Where a rechargeable flashlight is less suited to the task would be in the situation of having an emergency flashlight that is seldom used, but which will absolutely be a lifesaver in the event of a bad storm, etc. Here, you’d be much better off with an alkaline-powered flashlight, which will hold its charge between uses for much longer.

Another item to consider is the charging method. Some lights come with dedicated, sealed-in batteries and an integrated charger. Others have external chargers, and you take the batteries out to charge them. The latter can be more flexible, if your usage is high and you’re concerned about not being able to use your flashlight while it’s charging.

Similarly, how you plug in the flashlight or charger is another consideration. The heavier-duty flashlights will typically plug into a wall socket to charge, but a lot of smaller flashlights can now be charged via a USB connection. These can be slow to charge, however, so it’s important that you check the specs and decide whether the characteristics of a particular flashlight are right for you.
