How does a percolator brew differently from a drip coffee maker?

A percolator cycles boiling water up through the grounds repeatedly, so the coffee keeps passing through the bed. That gives a strong, full-bodied cup but can turn bitter if it stays on the heat too long. Drip brewers pass water through the grounds once.

Does it keep coffee hot after brewing?

Yes. Like most electric percolators, it has a keep-warm base that holds the pot at serving temperature after the brew cycle. Long holding times keep cooking the coffee, so flavor fades the longer it sits.

What voltage does it need?

It is rated for 120V, the standard US household and office outlet. It is not a dual-voltage appliance, so it needs a step-up converter abroad.

Is stainless steel better than glass or aluminum for a percolator?

Stainless steel resists dents, staining and corrosion and holds heat well. Glass lets you watch the brew but chips, and aluminum can react with acidic coffee over time.

Can I use it for tea or other hot drinks?

It is designed for coffee, and the percolating basket is built around coffee grounds. Using it for tea leaves or spiced drinks can leave flavors in the pump and basket that carry into the next pot.
