As I am an ignoramus on electrical issues, I do need explanations I can understand. Would you be so kind as to help me over an issue I am completely confused about?
I have electronic equipment like laptop and mobile phones which I want to take with me to the Philippines from the UK (on holiday). The rectangular input/output box adaptor (which came with the laptop) and the plug (which came with the mobile phone) state "for indoor use only. Connect only to grounded outlet" I do not understand what that means.
My adaptors (which came with the laptop and mobile phones) are DC (I think) because they both have 3 pronged plugs and were bought in the UK. Are the laptop/mobile phone known as "the outlet"?
If so, how do I know if the outlet is grounded (earthed?) or unearthed? Does that mean I cannot use them en flight or within the Philippines because (I believe) they are AC (does AC mean unearthed?) ?
Also, I have bought extra adaptors (with 2 prongs - one circular prongs the other non circular prongs) to fit onto my 3 pronged plugs for use en flight and in the Philippines, but as they state they should not be used on "earthed" appliances it looks like I cannot use them on my "earthed" products. Am I right? if so, what am I to do?
This is what is written on the instructions of the circular 2 pronged adaptor:
"this adaptor does not alter voltage, use only with class 2 non-earthed appliances, for temporary infrequent use only, do not exceed the maximum load;10A, 250V a.c. 2500W"
This is what it says on the other adaptor:
"allows UK 3 pin (class II) unearthed appliances using 2 core cable to be used in the Far East, do not use earthed appliances with this adaptor. This adaptor does not convert voltages, use only with appliances operating on 110-250V 7.5A max"
I don't understand any of this terminology on either: I would be so grateful if you would be able to help me understand what I need to do. Thanks so much
