Will I need a power converter for my laptop? (U.S. based.) to Philippines?
It's a standard U.S. Dell laptop. I'll be in Manila, mostly in a hotel for a conference.
What they said. BUT you may wish to pack some form of spike and anti surge protector OR do due diligence on how good the Manila power quality is. It may be excellent for all I know - but some major cities are not. Many modern switch mode power supplies are relatively immune to spikes and surges - but a spike suppressor can be good insurance.
Wikipedia has some pretty extensive information about power standards around the world. According to this information, the Philippines uses types A, B, and C plugs:
However, it operates at 220V, 60Hz. The US uses 120V 60Hz. So while your US plugs (Type A & B) will physically fit into the sockets in the Philippines, you need to be sure your devices are electronically compatible with 220V.
Most modern electronics (laptops, for instance) have auto-sensing power supplies, which accept 110V-240V, and adjust accordingly. Here's an image of my laptop power supply, with the relevant info circled (Which reads INPUT: 100-240V~1.5A 50-60Hz):
Some older electronics will have a switch you can toggle between 120V and 220V. You'll need to check your individual devices to be sure.
It's unclear to me from this information if you may find yourself in a situation with only a Type C plug. You may want to get a Type C to Type A adapter such as this one just to be safe.
