I would say get one that rechargeable with a built in battery. While you can theoretically just use enloops or something in this one, it would be just so much easier with some time of USB charging and a built in battery.

Rechargeable via USB is nice, but for backpacking, it's nice to just bring 3 AAA batteries along if needed, instead of a USB powerbank.

I grabbed 2 to replace my ancient petzal headlamps I bought 20 years ago.

Thanks OP.

in this day and age, you might as well just get a lithium battery light. something with an 18650.. way way lighter and the light will last way longer, and you can recharge the battery.

but they make lithium headlamps that are both rechargeable AND replaceable.

there are lighter/more expensive options, but for something in this price range, you could pick up an 18650 based headlamp... a single 18650 has double the capacity of 3 aaa batteries. and weighs about the same as 4 aaa batteries. so youd be ligher and have more capacity just by bringing 1 18650, and if you brought a backup, youd have double the capacity with barely any extra weight. im honestly not sure why anyone would use aa/aaa batteries in a headlamp in 2025.

  • NiMH/alkaline batteries are cheaper
  • AA/AAA batteries are more readily swappable with your other devices
  • You can buy AA/AAA batteries at any convenience store
  • NiMH/alkaline batteries pose a lower fire risk than Li-ion
  • AA/AAA headlamps are generally cheaper than Li-ion headlamps
  • Most chargers support AA/AAA NiMH batteries; not all support Li-ion
  • 2-3 AAA batteries (most common for headlamps) is still lighter than 1 18650

Good deal especially if you prefer replaceable batteries for no downtime. Bright enough and rain resistance for most tasks

not once you calculate in their lifespan. lithium is far cheaper over their lifetime.

only if you refuse to leave the stone age and keep buying old tech.

you dont need to buy 18650 at the corner store because they last forever. I'm on about 10 years with some of mine that still show over 90% capacity. Any nimh battery would be damn near worthless in half that time.

we live in a world with thousands of millions of li batteries and fires are pretty rare. This is a pretty silly argument at this point. But not technically untrue, so "OK, I guess if you want to worry about something very very rare, don't get a lithium battery. But also you migh twant to return all your cordless tools, and most of the non wired electronics in your house.

if you cant afford a $15 headlamp, then im not sure what to tell you. they also last a lot longer because they are usually better built.

most lithium powered headlamps ARE the charger.

i already addressed this. capacity vs weight, the lithium blows it out of the water. when you have to carry 4-6 aaa's because the capacity is tiny, you are better off with an 18650. the only way aaa wins out is if you are buying lithium aaa.

there are niche needs for the aaa headlamps. 95% of people would be better off with 18650. most people that think they need aaa are just stuck in the stone ages. like yourself. bruh.

Wait for the Wurkkos HD10 to go on sale. Check Amazon. 100x the flashlight this Energizer is and a real hobby grade w/ replaceable batter and USB-C chargeable. It's BRIGHT. Cool I just bought one for $20 two days ago.

At this time, any lamps, flashlights etc using a conventional battery (AAA, AA, C, D etc) is a waste. Always get a rechargable lamp with an 18650 or similar cell using USB-C as the charging port.
