I don't get you point unless we are talking taking your TV? If you look at your charger for batteries, cameras, or about anything else made in Japan, Taiwan, China, Indonesia, India, and yes even America they work of both 110 and 220 50 to 60 cycles. I have been traveling to Fiji for ten years and also have hundreds of dives and many weeks of staying there and have never needed a Converter! But have seen them over heat and cause problems as well as one more heavy thing to pack! The Surge Protector must be able to handle 220, but the system works great! Now if you have some kind of requirement for Sine Wave sensitive piece of electronics then by all means us one, but the transformer built into most chargers will work fine! I once ordered an electronic item from the internet and it came with both US and Slant cords and both plugged into the same charger! But if anyone wants to spend the extra money remember it's your to spend!
BTW the burst thing is very funny and completely wrong! But funny! The polarity reverses and has nothing to do with a burst or surge! Alternating current in order to transmit it over longer distances to over come resistance, ask Mr. Ohms!
