I’ve been putting the new **EcoFlow STREAM 5000** through some proper real-world testing.
Is it really a 5kWh battery? How efficient is the inverter? Can a single unit actually handle high-power appliances like a kettle? And how does it compare with the previous generation?
In this video, I test the EcoFlow STREAM 5000 AC from 0–100% and back again, measuring exactly how much energy goes in and how much comes back out.
I also test:
* Real usable battery capacity
* Round-trip efficiency
* Performance at 800W and 300W loads
* A 2.37kW kettle test
* Charging at 2kW
* Thermal performance and temperatures
* Standby power consumption
* How the new inverter compares with the previous STREAM generation
The results were actually better than I expected. At higher loads, the STREAM 5000 delivered almost its full rated capacity, and the inverter handled a full-power kettle without any trouble.
At lower loads, efficiency drops as expected, which is an important consideration if you're planning to use one of these primarily to cover a small household base load.
This is just the start of my testing. Next, I'll be looking more closely at smart meter performance, responsiveness, load following and how the new STREAM compares directly with the older model.
If you're interested in home batteries, plug-in solar, solar panels, EVs and reducing your energy bills with real-world testing rather than just manufacturer specifications, make sure you're subscribed.
