## Our score

- Score 4.9 out of 10
- Owners’ ratings, 30%: none yet at the shops that deliver to the Netherlands, so this part is left out and the score is the features part alone.
- Features, 70%: 4.9, 37.91428571428571 of the 78 points for the maker’s facts, and the other 22 points counted at the market’s average share of 50%.
- Price does not count, so a discount never lifts a model. A home battery is ranked only when its kind is known and its maker states the usable capacity, the round-trip efficiency on the AC side, the standby draw and the warranty. A battery module is not ranked.

## Who it suits

**Good for**

- No panels: charges from the grid at up to 1,200 W (https://de.ecoflow.com/products/stream-ultra-x)
- Charge when power is cheap: follows a dynamic tariff and charges from the grid (https://de.ecoflow.com/products/stream-ultra-x)
- Keep power during a cut: a backup socket during a cut (https://de.ecoflow.com/products/stream-ultra-x)
- I plug it in myself: plugs into a wall socket, an electrician for more power (https://de.ecoflow.com/products/stream-ultra-x)
- In a shed or garage: warms itself in the cold (https://de.ecoflow.com/products/stream-ultra-x)
