Amazon has the Belkin Travel RockStar Surge Protector on sale right now, coming in at $8.99. That's a great price for this surge protector, considering it is usually priced at around $15. And it's a great pick up for those that do a lot of traveling since it is pretty small and compact and can fit into your bag pretty easily.
The Belkin Travel RockStar Surge Protector comes with two AC outlets, a USB port, as well as a 3000mAh capacity battery built-in. And that's what really makes this unique. It doubles as a portable charger, so even if you aren't near an AC outlet, you can still charge your smartphone. Now obviously at 3000mAh capacity, you aren't going to get a whole lot of juice for your phone here, but you will be able to top it off pretty quickly and easily. This surge protector also has two AC outlets, which is great for plugging in something like a laptop, or if you're in a hotel room that only has one outlet, you can easily make it have two with this one. Which is why it's so good for traveling. On top of that, it's also pretty small and compact, so it won't use much space in your bag when you're traveling.
