Adaptor for Belgium and germany

You just need the standard European two (round) prong adapter. I think Rick sells them here in the shop or you can buy them on Amazon. The individual adapters are the simplest and lightest but if you have more than one device that needs charging, you might consider a multi-country adapter that has charging ports built in.

Your hotel may or may not have USB ports. This is the adaptor we have taken:
