Check the total wattage consumed by your electrical devices and multiply that number by 3. You need a converter at least 3x the watts of the devices to leave enough room for surges in power they may utilize. To determine the correct wattage allowance of the voltage converter/transformer you need, first identify the wattage of the electronic devices or appliances you plan to use. This information can be found on the manufacturer's label located on the back or bottom of the device or appliance, or in the specifications section of the appliances' owner's manual. Note: Watts may be listed as "W" on your appliance. If you can't find "Watts" or "W" on the label, you may find "Amps," also known as "amperage" or "A". If only the amperage is shown, multiply the input voltage by the amperage to find the wattage. Use the following example as a guide: Volts x Amps = Watts or 110V x 1.5 A = 165W. After totaling the watts of all the devices for use with the transformer, add up the total watts and multiply that number by 3. Review: Stabilizer - It works in Nigeria. Thank you. Review: Voltage converter- extremely heavy otherwise great product - Great product. Needed to buy after purchasing an iron that came from Germany that had voltage of 220 rather than the 100 voltage common in the US. The more wattage you need the more expensive so it was a bit pricey. I like that you can switch from 110 to 220 & vice versa. The one drawback is it is extremly heavy, too heavy to travel internationally with & the carring handle is a strap on top that I can barely get my hand under it so I need to pick it up & carry it as I would carry a hevy box. ## Features - SAFETY - PROTECTION & WARRANTY: Overload Protection – Overheat Protection – Fuse Protection – Best in Class 5 Year Warranty – Extra Durable Lifetime Coil - CE Certified – 5 Year Limited Warranty - PROVEN PERFORMANCE MILITARY APPROVED – When only the BEST is acceptable look at none other than Dynastar.
