Review on 🌍 FOVAL Power Step Down Voltage Converter 220V to 110V with 4-Port USB International Travel Adapter - Use for US Appliances Overseas (China, UK, Europe, etc.) by John Wei

Possibly the most dangerous thing I've ever bought. I bought it for use in Argentina and now that I'm there I have 2 USB devices plugged into USB and a small alarm clock plugged into a regular plug. After about 50 minutes there were 3 very loud clicks and the device started throwing sparks at the wall and wooden table and then caught fire. It's a miracle I was by his side when it happened, otherwise the whole building could have burned down. It's been 32 days since I ordered so no help from Revain. The FOVAL seller/manufacturer claims an 18 month warranty and is reluctant to refund, suggesting that I overcharged their product, which is NOT true. And even in this case, the ignition of communications should not begin. This is one device I could never leave unattended! ATTENTION! Do yourself a favor and DO NOT BUY THIS!
