Begin with the same kind of product
A standalone station, an extra battery and a station-plus-panel bundle are different purchases. Compare the base units first, then account for the accessories you actually need.
Keep region visible
A model-family name does not guarantee matching sockets, voltage, firmware or support in every country. This Index labels its source market; that is different from a verified local offer.
Read disagreements rather than averaging them
Our MARSTEK M1200 research includes an EU source stating 1,200 W and a global catalogue stating 1,800 W. We show a conflict. Averaging those figures—or choosing the larger one—would create a claim supported by neither source.
Missing is not zero
An unestablished weight does not mean a product weighs nothing. An unanswered expansion question does not prove expansion is impossible. Keep these unknowns visible and focus further research on whichever detail changes your decision.
Compare price on the same basis
A dated catalogue price can be useful context, but it may not be a purchasable offer for the same regional package. Check included accessories, seller, delivery and tax before drawing a budget conclusion.
