Ok, as a sink for laundry when traveling because I can't use laundry services due to allergies.

Brilliant invention, I now have a couple of these and I'll buy them for other headlamps too.

A smart alternative to batteries. The instructions said to charge it while it's in the headlamp, but the battery doesn't want to stay in there and keeps popping out. When you close the lid, it seems that due to the shape, the lid doesn't close as tightly as it does with batteries (waterproof?).

Good battery. Ordered 2 weeks ago. Used occasionally with a 5-year-old Petzl headlamp and haven't had to charge it again here in the cold of Lapland. Good purchase! I didn't need to start buying a lamp, when this one turned out to be doubly great. <3

A handy battery that you can get in place of 3 AAA batteries.

It works well and with a single charge, the running time for jogging is sufficient.

Good battery, I recommend it if you use the headlamp a lot, saves battery costs.

I got the first battery inside the headlamp I bought, and pretty soon I noticed that the lamp flickers and the light doesn't last long. The fault turned out to be in the Li battery. Varuste.net nicely delivered a new battery that is functional.

Battery lasts for days, slow recharge but good for battery life. If you have two you can never go dark

Excellent accessory, replaces AAA batteries and apparently lasts a significant amount of hours on a single charge.

Handy storage for those who can't afford to buy and recycle batteries or charge separately. A big plus is that you don't need a separate charger, but the charging port should be USB-C instead of micro-USB (this is practically the only device I own that requires micro-USB).

Very good solution. Simple device, easy to use. Charging, when ready installed in the Petzl headlamp, ready to use. Also the akku keeps its promised working time.

Long-lasting battery, the price of a single battery is a bit salty

Quite a clever idea. Wins rechargeable batteries 10-0. The downside is that the charge is on micro-USB and not USB-C. Fits Tikka headlamp, but I had to stab another Petzl headlamp to fit.

Easy extra time for headlamp. Charging should be USB-C rather than micro-USB and a bit faster.

A couple of these so stay on the parsley in action. Easy to charge on the ground from a bigger powerbank, but you grab two because it can be removed for charging.

Good battery life and works. Sufficient lighting for walking and running. There needs to be a stronger light for the bike.
