TESSAN 220 to 110 Voltage Converter US to Europe, International Travel Power Adapter with 4 USB Ports(2 USB C), 2 AC and EU/UK/AU Plug Universal Power Converter Adapter Combo, Step Down Transformer
Quick take
This TESSAN converter combines a step-down voltage function (220 to 110 mode) with a universal travel adapter and four USB ports for charging multiple devices in one compact unit. It’s a good match for travelers who need to run common US appliances on 220 to 240 V outlets and also want USB power for phones and accessories.
The main caveat is that the AC outlets are intended for certain appliance types, not very low-watt devices, so it’s important to check whether your device is compatible with the converter’s intended load behavior.
Pros and cons
Pros
- Step-down conversion mode for 220 V to 110 V travel power (up to 2000 W max).
- Works as a universal travel adapter, covering multiple plug types across Europe, the UK, and more.
- Includes 2 AC outlets plus 4 USB ports (2 USB-C, 2 USB-A) for charging several devices at once.
- Compact, lightweight form factor designed for travel.
Cons
- AC outlet function is not suitable for very low-watt appliances (0 to 5 W) such as electric shavers or toothbrushes.
- USB charging is capped by total output limits, so you still need to plan around high-power charging needs.
- Some step-down behavior may not work as expected with certain devices, so device compatibility matters.
What buyers think
Buyer feedback is generally positive around real-world travel use. Several shoppers reported that it worked well in the UK and other European locations for typical travel electronics, and they liked the convenience of having multiple connection choices (USB and AC). There is also mention of a minor buzzing or whine, though one note suggests it may have been related to the local mains supply.
There is at least some limited negative evidence tied specifically to the step-down voltage purpose, where a device reportedly ran briefly and then failed. Because the overall review evidence is mixed and device-specific, compatibility with your exact appliance load is the key uncertainty to evaluate before relying on it for sensitive or high-risk devices.
How this voltage converter works (and why it matters)
This unit offers two conversion modes, so you can choose the behavior that matches what your destination outlet provides and what your device needs.
- Converter status (red light on): It automatically steps down 220 V to 240 V (50/60 Hz) to 110 V (60 Hz), with a stated maximum of 2000 W.
- Adapter status (green light on): It provides output in the 100 V to 140 V range with a stated maximum of 1120 W.
In practice, the big buying decision is whether you need true step-down from higher-voltage outlets for your US device. If you are unsure, check your appliance label for its required voltage (for example, 110 V versus “110-120 V” designs) and understand that some appliances may be more sensitive than others.
Plug coverage and charging ports
The TESSAN is designed to handle travel plug needs across multiple regions. It’s described as working in places including Europe (with emphasis on Type C, G, and I adapters) as well as the UK and Ireland, Australia, and New Zealand.
On the power side, you get a total of 6 outputs:
- 2 AC outlets (for plug-in appliances, depending on compatibility and mode/load)
- 2 USB-C ports (5 V, 3 A per port, up to 15 W max overall for that type)
- 2 USB-A ports (5 V, 2.4 A per port)
The total stated USB output for the device is 17 W max, so while you can charge multiple items simultaneously, you should avoid expecting high-power performance that exceeds those limits.
Pros and cons (practical buying view)
Best for
- US travelers heading to 220 V to 240 V regions who need both AC outlets and USB charging in one compact converter.
- Multi-device packing, where you want phones, cameras, and small accessories handled via USB while you reserve the AC outlets for appliances that need 110 V.
- Common hotel and cruise usage scenarios where you’ll plug in typical travel electronics and short list of AC devices.
Who should be cautious
- Anyone relying on very low-watt AC items (the unit notes 0 to 5 W devices, like electric shavers or toothbrushes, are not suitable).
- Users with devices that are sensitive to power behavior, especially if the appliance depends heavily on stable voltage timing or internal requirements.
- People planning heavy simultaneous USB + AC loads, because total output limits still apply.
Power and safety limitations to plan around
The converter includes protections for overload, overcurrent, and short-circuit, and it’s described as operating silently. Still, protections do not replace correct mode selection and load matching.
Also pay attention to the usage note: AC outlets are intended for “simple mechanical motors,” and they are not recommended for 0 to 5 W devices. If your appliance is outside the intended category, you may be better served by an alternative that explicitly supports your device type.
Verdict: is it worth buying?
The TESSAN 220 to 110 Voltage Converter makes sense if you want a travel-friendly, multi-output solution for trips to 220 to 240 V countries, with the convenience of universal plug coverage plus USB charging. It’s particularly appealing when you have a small set of AC appliances that truly need 110 V and you also want to keep USB charging consolidated.
However, if your travel routine includes very low-watt AC devices or you need maximum certainty for a specific appliance that may be sensitive, you should verify compatibility before depending on the converter for that device. For the right buyer, it can reduce packing bulk, but it is not a one-size-fits-all substitute for every type of electronics load.

FAQ
What voltage does this converter output in step-down mode?
In converter status (red light on), it steps down 220 V to 240 V (50/60 Hz) to 110 V (60 Hz), with a stated maximum of 2000 W.
When should I use adapter status instead of converter status?
Use adapter status (green light on) when you want output in the 100 V to 140 V range, with a stated maximum of 1120 W. If your device requires true 110 V step-down from 220 to 240 V, converter status is the more relevant option.
Can I charge multiple devices at once with the USB ports?
Yes. It includes 2 USB-C and 2 USB-A ports (4 total USB ports) plus 2 AC outlets. The USB portion has a stated total maximum output of 17 W, so charging speeds depend on how many devices you connect.
Are electric shavers and toothbrushes compatible with the AC outlets?
No. The unit notes that the AC outlets are not suitable for low-wattage devices (0 to 5 W), including electric shavers or toothbrushes.
What plug types does it support for travel?
It’s described as using adapters for Type C, Type G, and Type I, and it’s marketed for use across Europe, the UK and Ireland, and also places like Australia and New Zealand.
