Don't buy to power a modern smartphone.
Reviewed in the United States on May 31, 2020
The light modes worked well, but as a USB power bank it will not charge a modern smartphone. I bought one and plugging in my Note 10 charged it by one percent and immediately drained the battery on the light. I thought this was a broken unit but the replacement behaved the same way. While the build quality is good, a modern USB bank should not be essentially shorted out by plugging in a high-drain device and as someone else said the magnet on the back does not have enough power to hold the light against gravity, perhaps the smaller size one would be able to. If this light had proper battery circuitry and a slightly stronger battery it would be easily worth more than it's price, but as is it is just a good light.
