Is a Canadian three-prong laptop power supply safe to use with a two-prong EU adapter?

I'm in Belgium with a Canadian laptop power supply that has a three-prong plug. I only have a two-prong adapter for EU outlets and have already used it for several days. The supply is rated for 230 W with a 19.5 V / 11.8 A DC output, and its AC input label says 100–240 V, 50/60 Hz. When I tried reversing the setup, I could feel a slight static sensation on the laptop's metal surface. Is it safe to continue using this adapter, or do I need a properly grounded EU cable or adapter?

You probably don’t need a step-down transformer because the supply accepts the full European voltage range. Look for a locally available grounded travel adapter, electronics-store cable, or compatible IEC C5 ‘cloverleaf’ lead. Until then, unplug it if there’s any tingling, heat, smell, sparking, or other unusual behavior.

MapleOrbit42: The label does say 100–240 V and 50/60 Hz, so I ordered a grounded adapter and will stop using the two-prong setup until it arrives.

Check the AC input label first. Since yours is rated for 100–240 V and 50/60 Hz, it can operate on European mains without a voltage converter. However, the two-prong adapter removes the protective earth connection. Get a properly grounded North American-to-EU adapter or, better yet, an EU mains cable that fits the power supply. Don’t keep using it if you feel tingling or static on the laptop.

The main issue isn’t the output rating; it’s the connection to the wall. A three-prong supply is designed to have its earth pin connected, and a cheap two-prong adapter may leave the casing and laptop less protected if an internal fault occurs. A proper earthed adapter or replacement EU cable is the safe solution.

A hotel, travel shop, pharmacy, electronics store, or general department store may have a suitable adapter sooner than an online order. Make sure it is rated for the mains voltage and preserves the earth connection; don’t just force the three-prong plug into a two-prong arrangement.
