ROCKSTONE POWER Rockstone Power 1000 Watt Heavy Duty Step Up/Down Voltage Transformer Converter, 110/120/220/240 V, 5V USB Port

Does the job of upping the power so we could use our 220v hair dryer in the 110v North American electrical sockets.But the wife said the 220v power conversion wasn't 1:1. It's not giving the same amount of juice as we had while in Asia. Still overall better than nothing.edit: Burnt out after 7 months.... Heard a loud sound the hair dryer and the Rockstone shorted out.. :(

Fait le job, j'ai ramené toute mon électronique en 220v de France et il fonctionne super bien!Voilà un mois qu'il est branché sans arrêt dans mon meuble Tv.J'avais peur qu'il fasse du bruit, mais non après une minute de fonctionnement il reste silencieux.En revanche n'oubliez pas de diviser par deux vos besoin, donc 500w max pour celui de 1000w en crête.

So far so great with this product. I was able to take my 600W food processor to France and use it regularly, thanks to this convertor. A bit heavy to travel with but it was worth it. Seems quite durable. No weird smells or sounds or anything negative, except the weight in my carry-on luggage!

Arrived on time, exactly as described... I use it for a food processor (800 watts) and never failed me. A nice addition is the USB charging port. Only downside is its weight is more to the heavy side

This has been so helpful to me when i vas overseas for extended periods of time. you've got to have one if you have power requirements above charging your phone
