my thoughts on the ST-300

it was the day of my flight to europe, and i just realized last minute that european power is 220.. lucky my flight was later, i went to B&H, which the sales desk recommended me this from what i was needed to have a surge strip. this thing weights about 5 lbs, put it in my check in bag, no problem with my suitcase topping out at 48 lbs. this thing works as expected, i was able to plug all my camera chargers, usb plugs and my laptop. it was worth it on my trip.
Excellent

For the cost of radio shack plug you get you a 300 watts transformer plus a plug for every voltage.

It uses a half amp fuse. It comes with a total of 3 fuses. You should not ever need to change the fuse unless you exceed 300 watts.
