Are your clients frequent international travelers?
Then give them a useful and convenient gift that they can take anywhere. Why don’t you customize a universal travel adapter to fit various power sockets – can even include USB charging option…
Universal adapters you can find on the market usually cover all the major countries. You could also go for a simpler item for just a few markets or a complete model for all eventualities. Change the logo and color printing on the adapter to make this stand out. Chose a variety of different shapes for this item or a carrying pouch to suit your brand image.
