Universal travel adapter with four USB ports

The DISGIAN SL-199-3U-T combines a worldwide AC socket and four USB outputs in a single blue unit. It accepts 100 to 240 Vac input and fits outlets in over 150 countries. Three USB-A ports and one USB-C port share a total 3.4 A at 5 V. A red LED shows when power is present.

Sustained multi-device charging

The adapter delivers its rated 3.4 A continuously across all four ports without throttling. Built-in safety shutters and a spare fuse protect the AC socket and USB outputs during extended use. The AC outlet remains available while USB devices charge, supporting a combined load up to 6 A.

Total USB current of 3.4 A

This single figure determines whether the adapter can charge your phone, tablet and accessories at the same time. It does not convert voltage, so appliances must accept the local mains supply. Travellers needing higher USB power or voltage conversion should choose a different device.

Questions about this item

Does the 3.4A total output across four USB ports generate noticeable heat during all-day charging?

The adapter delivers a combined 3.4 amps at 5 volts across three USB-A and one USB-C port, and the supplier notes standard output speed with no special cooling mentioned.

What plug types must I already have on my devices for the USB-C and USB-A ports to connect?

Your devices need standard USB-A or USB-C cables; the adapter provides three USB-A ports and one USB-C port with a total 3.4A output.

Will the 100-240Vac input and sliding US, EU, UK, AU pins work with older 120V-only appliances I still use?

The adapter accepts 100-240Vac and includes US, EU, UK and AU plug sliders, but it does not convert voltage — connected appliances must support the local mains voltage themselves.
