power strip

Why not just get a US board with the number of sockets you require and a Euro power adapter?

Would you care to clarify? I am looking for a power strip.

Something like this?  A PDU - Power Distribution Unit - will have universal connectors...the same IEC320 C13 socket is used by almost all computer equipment.

Here, you supply the proper supply cord for your AC mains connection.  Then, you use what most people use as a computer power cable extension to connect the equipment.

Get your powerstrip with however many US sockets you want and add a Euro plug adaptor Like you'd buy if you were going on vacation.

This will deliver 230v 50Hz AC to all the US sockets on the powerstrip so depending on what you are connecting may not be a great move unless all your equipment already runs at 230v or has built in transformer switching.

Otherwise you are going to need to convert the output from the Euro wall socket to 110v so you'll need a step-down transformer. What you buy for this stage will depend on the total power load (V x A) for the power strip at maximum use

Thanks for the suggestion. However, I would like to dispense with physical adapters altogether. I am looking exactly for what I am asking about: an already-assembled-and-available-to-buy power strip with a European plug that goes into a wall socket and multiple US outlets on the strip itself. And I am going on a trip and would like to take this with me.

OK how many sockets do you need?
Will everything you plug in be able to cope with 230v?
What's the maximum current you'll draw through the strip?

3-4 sockets. I have a laptop power supply which is 90 W 110-240 V and a phone charger which is 300 mA. Therefore, not too much current.

Thanks. That works
