Universal travel adapter with four USB ports

The Unidapt SL-199-4U combines a universal AC socket with four USB ports in a single blue unit. It accepts plugs from over 160 countries including US, UK, EU and AU standards. The USB section delivers up to 2.4 A at 5 V for phones, tablets and similar devices. An intelligent charge IC detects connected hardware and adjusts output automatically.

Travellers charging several low-power devices

This adapter suits anyone who needs to run a laptop charger plus multiple USB gadgets from one foreign outlet. It is not for appliances that draw high power such as hair dryers or kettles because the AC socket is limited to 6 A. Buyers who need voltage conversion should look elsewhere since the unit does not change 110 V to 230 V or vice versa. Only dual-voltage equipment rated 100–240 V can be used safely.

Simple plug-in with one common mistake

Insert the correct slide-out pins for the destination country and plug the unit into the wall socket. Devices connect to the AC outlet or any of the four USB ports without further setup. The most frequent error is ignoring the 6 A AC limit and connecting high-wattage appliances, which can trip the internal protection or damage the adapter. Always confirm each device supports the local mains voltage before plugging in.

Questions about this item

What type of wall outlet do I need at my destination for the SL-199-4U to plug into?

The adapter includes US, UK, EU and AU plug formats that cover outlets in over 160 countries worldwide.

Can I keep using my existing single-voltage hair dryer rated for 110 volts with this adapter in a 230-volt country?

No, the unit does not convert voltage; it only passes through the local mains supply, so single-voltage appliances will be damaged.

How can I verify the USB ports are delivering the rated 2.4 A after I plug everything in?

Connect a device that shows charging current, such as a phone with a battery-monitor app or a USB power meter, and confirm it reads up to 2.4 A per port.
