Question: How do you determine whether a surge has occurred and the unit must be reset or replaced? There is no check light to verify that protection is active.
Document: The Belkin Power StripBelkin BST300 SurgePlus 3-Outlet Mini Travel Swivel Charger Surge Protector with Dual USB Ports (2.1 AMP / 10 Watt)offers two additional USB ports (aka the universal power source. USB chargers do not vary by country) and has a light that indicates whether the surge protection is active or not. It's minor but comforting as a consumer. 2) Mine had to be broken in slightly as the plugs were a little bit hard to insert.
I purchased this in January. I can't remember if I tested it when I got it. I can't imagine not plugging it in, but I don't remember specifically. Word to the wise - check yours as soon as you get it, and verify the reset button is functional.My early Feb overseas trip was cancelled, but I took it to Europe in May. Won't work on any plug - US or European, on either continent. Yes, I tried the reset button.
This item worked great in Beijing to add outlets and give surge protection (although I don't know whether I had any power surges in my hotel). It's small and the cord wraps around the device and plugs into itself, making it easy to pack. The cord is very short, though, so best for a desktop or night table-top application. Worked well also to take to the office with me so I only needed one power adapter for multiple devices.
We purchased this unit for an extended stay in China. China uses 220v/50hz like Europe. We are using multipal plugs from our iPads, Mac book pro and iPhones. The unit handles everything well. Compact to travel with and light.
Very pleased with this power strip for international travel. Plug it into the local country's power outlet using the appropriate adapter and presto, you have three universal outlets. Compact, light and easy to use and best of all - rated for the higher voltages used in other (than US) countries. I also like how the short cord wraps around the unit and plugs into one of the outlet. It will be with me on all future trips.
So in a power surge it will shut off all transmission of energy, thus protecting your equipment. Then you hit the reset button and it's ready for more. Cnet has an article praising this method--no partial transmission of energy, no fuse that needs replacing, no surge protector that dies protecting your equipment. (Another reviewer says it has a fuse but I think they are mistaken. )The kind of surge protectors that absorb and defect excess energy divert that energy through the ground plug.
Because it is a nice size and works with 220V, I think I will correct the wiring and continue to use it, accepting that it does not provide surge protection.
I love these power strips so much that I have 5 of them. It's really hard to find power strips that are 110-240V, have surge protection *and* have a form factor convenient for travel. These are it. You can stop looking.
The Simran SM-60 Universal Power Strip 3 Outlets for 110V-250V Worldwide Travel was exactly what I was looking for. It provided additional outlets & the surge protection that I wanted for my recent trip. It's not too big or too heavy, which makes it perfect for travelers who aren't very good packers (me! ).
Most surge protectors have information on the packaging about the characteristics of the protection. This one did not and that made me suspicious about its ability as a surge protector. I opened it up, and I found that it only has a simple circuit breaker. I'm not an electrician, but my understanding is that a circuit breaker protects the _circuit_ when a device is pulling too much current - it doesn't protect the _device_ if there is a voltage or power spike.
Answer: yes
