SUMMARY

The discussion centers on the necessity of using a 3-pin earthed power adaptor in Boston, where both grounded (3-pin) and ungrounded (2-pin) outlets exist. Users confirm that newer outlets typically accommodate 3-pin plugs, while older ones may only accept 2-pin plugs. It is recommended to have a 2-pin adaptor for versatility, especially in older buildings. Additionally, participants clarify the difference between voltage converters and adaptors, emphasizing that the devices in question do not require voltage conversion due to their compatibility with 100-220V.

PREREQUISITES
  • Understanding of US power socket types (Type A and Type B)
  • Knowledge of voltage specifications (120V, 60Hz) in the US
  • Familiarity with the difference between power adaptors and voltage converters
  • Awareness of the implications of using grounded versus ungrounded plugs
NEXT STEPS
  • Research the specifications of US power sockets and their compatibility with international devices
  • Learn about the differences between power adaptors and voltage converters
  • Investigate the availability of power adaptors in Boston hardware stores
  • Explore the implications of using grounded versus ungrounded plugs for electronic devices
USEFUL FOR

Travelers visiting the US, electronics users needing to adapt their devices, and anyone seeking to understand the nuances of power compatibility in different regions.

Coming week I'm visiting Boston for a meeting, so I bought a power adaptor. I just realized it's an earthed one, so it has three pins. Will I be able to use that on all the power plugs, or should I get a two-pinned adaptor?

Newer outlets will have three plugs (we call it grounded in the US), older outlets won't, so a two prong would give you more options.
 
Just get one of these to plug your adapter into when needed.

Excellent idea dl! Monique, these are just pennies at any hardware store here, is there someone in Boston you can ask to get you one?
 
Monique, I'm not sure where you're staying in Boston - hotel or with friends - but any place with reasonably to-code receptacles have the sockets that take three pins. You should also recognize that power receptacles throughout the US are 120V, which is different from the 200V in many European countries.
 
Also 60 Hz, don't you guys use 50 over there? Although I think for most electronic devices the cycle shouldn't matter.
 
Hmmm, now I'm doubting. At least I'm staying at an expensive hotel (it was the only option), so maybe I should take the risk. On the other hand, the adaptor is useful world-wide and I don't want to get stuck with unground sockets (which did happen before).

The voltage is not a problem, I'll only be using a computer and my phone and they have transformers that can take 100-220V.

The adaptor must be British then, it says Earthed :smile: When I was in London the other week the hotel check-in person corrected me when I asked for the elevator, "we call that a lift over here" :biggrin:

You should have asked for the stairs. :wink:
 
If you're at an expensive hotel, the front desk will have EU-US converters.

The wording here matters: a converter changes voltage but an adapter doesn't. You probably need a converter.

That's true, but sometimes you find that receptacles are in hard to reach places and that what is offered you is the end of an extension cord that has only a two prong receptacle. That sort of thing might happen if you stay in a private residence or small bed-and-breakfast.

No, I need an adapter so that the power cord will fit the socket. The converter that's attached to computer/telephone power cords is already designed to take 100-220V 50/60Hz.

Somewhere in the house I should have a cheap unground adapter, so I'll keep the grounded one. If it won't fit I'll be able to use someone else's adapter or visit a shop.

hah, I almost forgot to activate my debit card for North America, almost got stuck without money :biggrin: Strange, it almost feels like I'm going home.
