Thailand Type O adapter for dual-voltage travellers

The Ceptics CTU-18 provides a grounded Type O plug for Thailand outlets and accepts standard North American two- or three-prong plugs. It is designed for dual-voltage electronics rated 100240V such as phones, tablets and laptops. It does not convert voltage and will not support high-powered appliances like hair dryers or single-voltage CPAP machines.

3-in-1 charging with 2.4A total output

The unit combines one USA-style AC socket, one USB-A port and one USB-C port for simultaneous charging. The USB ports share a maximum output of 2.4A, suitable for smartphones, tablets and similar devices. The AC socket passes through 120V from the wall outlet, so connected equipment must handle that voltage natively.

Ultra-compact design with safety protections

Measuring 1.6 x 1.6 x 2.6 inches and weighing 1.8 ounces, the adapter fits easily in a pocket or small bag. Built-in safeguards protect against overheating and overcharging during normal use. The grey-white housing is backed by a limited lifetime warranty from the manufacturer.

Questions about this item

Will the 120 V USA socket on this CTU-18 work with the two-prong charger I already carry for my phone?

Yes — the built-in USA socket accepts standard North American 2- or 3-prong plugs, including polarized ones, so your existing charger fits directly without an extra adapter.

How can I verify the USB-C and USB-A ports are delivering power once I plug the adapter into a Thai Type O outlet?

Connect a phone or tablet to each port; the device should show it is charging, and the total combined output reaches up to 2.4 A across both USB ports.

Does the package include a voltage converter for my 120 V-only hair dryer, or must I buy one separately?

This unit is not a voltage converter — it only adapts the plug shape. High-power or single-voltage appliances like hair dryers need a separate step-down converter.
