Pros and cons
Fossibot
Pros
- Output of 7,200 W is the highest figure listed for the brand.
- Capacity of 5,222.4 Wh paired with 7,200 W of output gives real headroom for high-draw kit.
- Ups mode is offered, which matters for carrying electronics through a power cut.
Cons
- The warranty runs 2 years, below the 5 typical in the portable power stations group.
- Support runs on email and help centre, so a phone line is not part of the service.
- A home battery is not among power station, solar generator and solar panel, while power station and home battery and power station, solar generator and home battery both list one.
Samduo
Pros
- Capacity of 6,028 Wh with output of 2,600 W covers whole-home evening loads.
- Warranty of 10 years is the longest among ranked home battery and balcony solar brands.
- The range spans home battery and balcony solar, so battery and balcony solar can be bought from one brand.
Cons
- Support runs on email and help centre only, so there is no phone line for installation questions.
- Entry price of €1,999 is high for this category, and output of 2,600 W sits below the category median of 4,000.
- WattCycle LiFePO4 focuses on home batteries alone, so buyers who also want balcony solar must compare a wider range at ALLPOWERS.

Questions about each
Fossibot
How much does a Fossibot power station cost to buy?+
Prices start at $399 across the portable power station collection. That figure sits mid-table in our data at 16 of 27, so it is neither the cheapest entry point nor the most expensive one. Larger units cost more, and the largest unit in the range is the one carrying 5,222.4 Wh of capacity.
What is the biggest output a Fossibot station can deliver?+
The largest unit delivers 7,200 W, the highest output listed for Fossibot. That places the brand at 6 of 24 on output, ahead of its placings on the other measures in this comparison. A station like that can run high-draw equipment that smaller units in the same category cannot.
Samduo
How much does a Samduo home battery cost?+
The entry price is €1,999, which is high for this category and sits well above the median of €262.21. That figure covers the Samduo plug-in home battery, and the same brand also sells balcony solar. Larger capacities cost more, so the final price depends on which unit you choose.
How long is the warranty on a Samduo battery?+
The Samduo warranty is 10 years, which is the longest among the brands ranked on this measure, compared with a category median of 5. Long cover matters most if you intend to keep the system through a house move, since a battery that stays with the property avoids resale friction.
