Worth it for the actual 1200W voltage conversion on tap, provided you plug higher-power devices into the correct AC2 or AC3 socket rather than AC1.

Overview
A 2000W travel power combo from TREVOLTY with one pass-through AC outlet for wide-voltage electronics and two true 220V to 110V converter outlets rated up to 1200W for higher-draw devices like hair dryers.
The key detail buyers need to keep straight is that only two of the three AC outlets actually convert voltage. The AC1 socket is a plug adapter only, so plugging a fixed-voltage US appliance into it by mistake would not step the voltage down at all.
- AC1: 2000W pass-through, no voltage conversion
- AC2/AC3: up to 1200W true voltage conversion
- 2 USB-C (PD 20W) plus 2 USB-A ports
- Type C and Type G plugs for 100+ countries
Who it's for
Travelers who need real voltage conversion for a higher-wattage US appliance such as a hair dryer or kettle, plus USB charging for several devices, rather than someone who only needs a plug shape adapter for a phone charger.
Pros and cons
- AC2/AC3 step down real 220V to 110V for devices up to 1200W
- 2 USB-C ports support PD 20W fast charging
- Included Type C and Type G plugs cover 100+ countries
- Overvoltage, overcurrent and short-circuit protection built in
- AC1 does not convert voltage, only reshapes the plug
- Not compatible with touch-screen devices on the converted outlets
Performance notes
AC1 is a straight pass-through rated to 2000W meant for devices that already handle a wide voltage range, like phone and tablet chargers. AC2 and AC3 are the actual converters, stepping 220-240V down to 100-120V for devices up to 1200W such as a hair dryer, kettle or iron, and touch-screen devices are called out as unsupported on the converted outlets.
