Many of us have had negative experiences abroad when we found out that our electronic devices do not match the wall outlets. The hotel administration may not want to hand out any adapters, since they are commonly never seen again. Thus, a universal power adapter can definitely be considered as a promotional gift, and not just for companies that deal exclusively in electronics or travel agencies. Clients who travel a lot will be very grateful for the numerous USB ports, which allow them to charge all of their smart devices efficiently. Make sure to print an elegant company logo on the side of the adapter. If You do this, Your client will look back at Your company with respect, each time they solve their charging issue – whether in a hotel, an airport or when travelling by train or bus.
