Very lower intensity of lighting than my expectations. I have purchased extra batteries and it lasts a very long time.

Here follows a terribly detailed text, buckle up.
Owner of 30+ lenses, always looking for the next one and this one I really like.
Amazing product in terms of design and versatility with excellent value for money. Just calculate that you need 2 good batteries.

The positives:
+ It is a work light (diffused light), strobe (in case of a car breakdown instead of a triangle) and power bank!
+ Its stand is very convenient for adjusting the angle of the light.
+ The batteries can be easily replaced, you just take them out and replace them. I consider this very important because it is a big scam when the batteries die and you either have to use pliers if you know how or throw away the product. Unfortunately, I believe that a branded product would rarely offer this flexibility due to planned obsolescence.

The so-so (negatives):
- It charges very, very slowly (I mean charging it, not charging something from it). With 2 LG 3500 mAh batteries, it took 11 hours to charge from empty to full with a powerful fast charger!!!
- Its plastics do not inspire great confidence, but it is not the typical cheap Chinese plastic that is flimsy.
- The batteries that came with it never worked, they didn't even accept charging, and this happened with 3 different chargers (2 Nitecore and 1 LiitoKala...). But when a good one costs €7 each and this light costs around €13, it would be unreasonable to have such expectations.

My suggestion:
- Change the batteries with better ones. With the ones I mentioned below, it lasted for more than 6 hours on high! Either get a 18650 battery with a head or, if you use flat ones that are more common, play around with aluminum foil or a magnet to make contact.

What I would look for in addition:
I would gladly pay four times the money to have a few more features... for example:
Faster charging, a magnet for support, better plastics and ports, type C charging, a third or even fourth slot for 18650 batteries, 2 USB outputs, waterproofing, another scale with even lower brightness for longer duration.

I bought this product because of the price, as it included 2 rechargeable 18650 batteries in the package. BUT the 18650 batteries (Ultrafire 4800mah) it includes are useless. They don't even last 15 minutes. They are not even mentioned on the official Ultrafire website, with a clear reference that the limit is up to 3000 due to the chipset. So, you will have to calculate the purchase of 2 other batteries (+20 euros, total 35 euros), so the advantage of the "normal price" is lost and it becomes expensive!
