Is this panel really 200W?

The title and most fields say 200W, but the kit contents and one wattage field say 100W. Ask the seller to confirm the rated output before you buy, and check the label on delivery.

Through MC4 it feeds a portable power station or, with a charge controller, a 12V battery. The USB-C and QC3.0 ports charge phones and small devices directly.

Does it need a charge controller?

For a bare 12V battery, yes. Most portable power stations have a built-in solar input and accept the panel directly through MC4 or an adapter.

It carries an IP65 rating, which means rain and dust resistance, not immersion. The junction box and ports still need shelter.

How much does it weigh and how big is it folded?

The listing gives only a 22.2-inch length and no weight. Folding 200W panels typically weigh 12 to 18 pounds, so check the spec sheet before carrying it far.
