I have a lot of electronic equipment,two different battery chargers, video camera, and computer. can I use converter and adapter with a powerstrip?

Technically, you can. But I don't know why you should. Most newer electronic equipments accept dual voltage, so you don't need to have the voltage converted. [And a converter that's rated enough for all your appliances can be big and heavy.]

Instead, just buy a few more plug adapters, if your appliances will accept 100-240V.

Someone mentioned about just getting one plug adapter and then bring a US-style powerstrip. That's not a good idea because most of the ones sold here are only rated for 110V, not 240. There might be ones that are rated for 200-240, but do check that.

Another problem with a power strip is that you don't know how much current the wall outlet can carry.

Check the input info for all your appliances. Since most, if not all, of them were manufactured for WORLDWIDE sale and use they will probably accept 110-240V input. If so, you do NOT need a "converter" or "transformer." All you need is a plug adaptor.

The power strip MUST BE rated for 240V...simple, VERY simple answer: go to a local hardware or whatever store IN Europe and buy one there.

Completely agree that it would be easiest to buy it there. I just looked at the power strip here and it's rated max 15A, 125V. Might be that Home Depot would carry a contractor's version for higher voltage (but check the plug config if you go that route as it may not be the typical 3 prong US wall outlet layout).

The downside though with the Euro powerstrip is that you'd need as many plug adapters as you have devices, as the outlets on that one would still be Euro style plugs.
