The JMFONE Universal Travel Plug Adapter is built for travelers who don't want to carry five different plugs. It works in 200+ countries with UK, EU, US/JP, and AU/CN plug configurations, and charges up to 4 devices simultaneously through 3 USB-A ports (2.4A max each) plus 1 USB-C port — 3.4A smart total output shared across all ports.
Important: this is a plug adapter, not a voltage converter — it does NOT convert 220V to 110V or vice versa. Safe for dual-voltage electronics (phone chargers, laptop chargers, cameras — most support 100–250V, check your device label). Do NOT use with single-voltage high-draw appliances like hair dryers, hair straighteners, kettles, irons, or coffee makers unless they're explicitly rated for dual voltage. Max pass-through: 880W on 110V circuits, 2000W on 250V circuits, only for compatible dual-voltage devices.
