Video at Amazon.com View 4-Port USB Charger from Inateck is supplied in a sturdy carton with a thin plastic shell inside for added protection. The processing is visually and haptically very stable. The design I would describe as a success.
In practice, all 4 ports are working properly, even if the unit is fully stocked. I had at least still complain no failures ...
All in all, a chic and cheap USB charger that should be in every suitcase.
