携帯電話を充電できるコンセントはありますかってって英語でなんて言うの？

If you would like to know if there are any outlets or anywhere to change your mobile phones, you can ask like this... "Is there a place close by where I can charge my phone?" This can be used in a general way rather than speaking just about an outlet.

Some airports have wall plugs dotted around that are used for maintenance staff and cleaning staff, however when the terminal is open these points are usually not in use, and so "Am I allowed to use the power outlets in the terminal to charge my phone?' is a polite way of asking the information people if you can use one of these wall outlets. Alternatively if there are no visible wall outlets the terminal may have a designated charging point and "Excuse me. Is there a phone charging point anywhere in the terminal?" is a polite way of asking about this.

The first answer is a very formal way to ask if you can charge your phone in a particular place. *'Establishment' = organization / premises. 'Facilities' = specific place or features to allow a particular thing to occur. The second answer is a more informal but polite way to request this. The third answer is very polite, and suggests that you are sorry if you are somehow being difficult by asking this question *'Impose' = to ask for or be involved in something where you perhaps might not be welcome.

With the increase in the use of technology, more places have adapted to this by including public Wi-Fi and outlets for charging. You may simply ask the person that works there or security if there is somewhere where you can charge.

"Would it be possible for me to charge my phone here?" You can use this if you are asking if there is any way they can allow you to charge your phone or if they could assist with charging your phone. "Is there anywhere I can charge my phone here?" Used to ask for a portal, an outlet or an establishment (shop) where your phone could be charged. "Do you by any chance have a charging portal I could use to charge my phone?"In this case, you are asking specifically for a portal to use in that specific place.

An electrical socket in the wall is - 'an electrical socket'. What you do with it is another question. If there is one or more such socket and it has been placed in a specific position to enable people to charge their phones, then it may be described as a 'charging point' or possibly a 'phone charge point'. In the UK, we do not call electric sockets 'outlets' as it seems is the the case in the USA.
