Keep your mobile devices charged & protected when you're on the road with this three-outlet, mini surge protector. Plug this USB travel charger into any wall outlet & power up to three AC devices at once without extra cords. 360-degree swivel feature allows the surge protector to rotate up & out of the way to prevent it from blocking other outlets. Two powered USB ports (2.1A combined) offer convenient one-source charging for your mobile devices, including tablets. A green light at the top of the charger indicates that surge protection is active so you'll never have to guess if the charger is working properly. Surge protector offers a high level of protection with its 918-Joule energy rating. Oversized metal oxide varistors (MOVs) absorb excess electricity for additional protection while damage-resistant housing protects circuits from fire, impact & rust, & prevents dents & scratches.
