Pros and cons

Pros

Projection patterns and adjustable beam offer more creative control than a basic fill light.
USB Type-C charging and claimed PD3.0 30W charging support make recharging more flexible.
The listing provides both full-power and lower-power battery-life claims, helping set expectations for shoot planning.

Cons

The claimed 70-minute runtime at full 25W output limits uninterrupted maximum-power use.
The light is listed as not water resistant, so it is intended for indoor use rather than wet conditions.
