Most airplane systems provide 70 watts maximum, but if you take out the battery you should be fine. Or you can charge the battery while the laptop is off.
2. I have an AT&T Wireless GSM phone that supposedly works in the UK (according to my company). I noticed that the power adapter for this phone only has a 110V input. Do I need to buy a transformer to charge this phone?
If the adapter is rated only for 110V, then you will need a step-down transformer to reduce the 220V of UK to 110V.
3. Radioshack sells plug adapters for use in the UK (among other places). Is this all I need?
For the laptop, yes. I bought the RS adapter set and my HP zd7000 also autosenses. Note the RC set is a two-prong input, so buy the 3-prong to 2-prong adapter. Worked like a charm in my hotel in London.
