Our verdict
Worth considering if you already own an EcoFlow Delta/River power station — PowerStream turns it into balcony-solar storage. Otherwise the newer STREAM line is the better buy.
Pros
- Reuses existing EcoFlow batteries
- Cheap
- Proven
Cons
- Older than STREAM
- Best value only if you own an EcoFlow battery
