No reviews yet
Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing details. This number counts only the evidence recorded so far. The source review for this product is not finished, or the maker has not disclosed enough, so the number can only go up.
Missing for this product: Certificates evidence needed; Warranty term needed; Warranty energy disclosure evidence needed; Cell model disclosure evidence needed.
Power stations · Output unconfirmed · Rated capacity
The warranty term and the lifetime energy are each scored against the best documented value for a power station: a value earns its share of that best, times the weight. A documented value always earns points; an undisclosed one earns 0.
Cycle rating disclosed · 20% weight
Documented cycle rating earns 20% of this criterion. More evidence is needed to compare lifetime MWh per kWh.
20 × 0.2 = 4 points.
The maker's documents disagree; the less favorable printed figure, 3,500 cycles, is scored. Warning: The user manual and the product page print different cycle lives.
