A horribly detailed text follows, fasten your seatbelts.
Owner of 30+ flashlights, I’m always looking for the next one and I really like this particular one.
Amazing product in concept and versatility with excellent VFM (value for money).

Positives:
+ It’s a flashlight (focused beam), work light (diffused light), strobe (e.g. if your car breaks down, instead of a triangle), and power bank!
+ Its stand is very convenient for adjusting the light angle
+ The batteries can be replaced at will, you just take them out and replace them. I consider this very important because it’s a big scam when the batteries go dead and you either have to solder if you know how, or throw the product away. Unfortunately, I believe it’s very unlikely a branded product would offer this flexibility due to planned obsolescence.

The so-so (negatives):
- It has a very, very slow charging time (I mean charging it, not charging something from it). With 2 LG 3500 mAh batteries, it charged from empty to full in 11 hours with a fast charger!!!
- Its plastics don’t inspire great confidence, but it’s not the typical cheap-Chinese plastic that’s flimsy.
- The batteries that come with it don’t have much life in them, but when a good one costs €7 each and this needs 2, it would be unreasonable to expect more when the light itself costs about €10. They do work though.

My suggestion:
- Change the batteries for better ones. With the ones below, it lasted 6+ hours on high! As another friend mentioned earlier, either get an 18650 battery with a button top, or if you want to use flat tops (which are more common), use aluminum foil or a small magnet to make contact.

What I would look for more:
I would gladly pay triple the price to have a few more features... e.g.
Faster charging, magnet for mounting, better plastics and better covers, type C charging, third or even fourth slot for 18650 battery, 2 USB outputs, waterproofing, another step with even lower light intensity.

Update: ALTERNATIVE SUGGESTION
I also bought the "Led Work Flashlight W840" and I prefer it because for just €3 more:
It does almost the same things but at 2/3 the size (see photo) and with better button texture, but it doesn’t have a flashlight (the side one with the beam) and doesn’t have the lights that show how charged the battery is. For me, much better just because of the size (see photo). Link:

Update 2025-06
The king of the category is here!
We’re talking about better light diffusion, multiple intensities and multiple color temperatures, type C, magnet, and more.
There is an option for built-in or removable batteries (which in my opinion is the better solution)
