The battery with its accessories is an excellent minimalist solution when you need to top up your phone, light your way, or put a small light on the table on the patio. The little box can easily be tossed into a backpack, bag, or purse and used when needed. You can also always buy an additional battery with a larger 6000 mAh capacity. At home, it is worth having a slightly better charger for this type of battery, because the built-in one is not very accurate. The price of the set is fair for what it offers; the battery itself is not cheap. Overall, a nice gadget :).

The idea is brilliant. The light it produces is superb. But there are still some very big issues: (-) It requires TWO cables (not included) 🙄: a USB-A to Micro-USB (increasingly hard to find these days) for the battery charger and a USB-A to USB-C (the most common case) to charge your device. That makes the whole setup a lot less compact. 🥴 (-) The battery + lamp assembly won’t stand up. Not on a table, not on anything else. (-) The battery + charger assembly has an annoying tendency to disconnect itself during charging (because of the cable being twisted). (-) Well, obviously, but... it only works with a *very* special battery model. In the end you wonder why all these bits are stuffed loosely into a box when it would have been much more efficient to integrate them all into one lamp body.
