OREI Denmark Travel Plug Adapter with Dual USB review
Quick take
The OREI Denmark Travel Plug Adapter with Dual USB is a compact Type K (Denmark) outlet adapter that lets US-style 2 or 3-prong plugs connect abroad and adds two built-in USB ports for charging two devices at once. It is best for travelers who have dual-voltage electronics (for example, many phone and laptop chargers) and need a secure, grounded connection when supported by their setup.
Pros and cons
Pros
- Type K outlet compatibility for Denmark (and similar Type K locations) with a US-style plug input.
- Two built-in USB ports, helpful when you only have one wall outlet available.
- Designed for a solid plug fit, with reviewers describing the outlet slots as secure and not loosening easily.
- Compact travel size, around 3 x 1.75 x 1.75 inches.
Cons
- Not a voltage converter, so it will only work properly with dual-voltage (100-240V compatible) devices.
- Bulky compared with basic plug adapters, which can matter in tight outlet layouts.
- USB port spacing can feel tight, making it slightly harder to insert and remove both USB chargers.
What buyers think
Buyer-review evidence is generally positive around fit and build quality. Multiple reviews describe a secure connection with firm outlet slots that hold chargers in place. Several travelers also highlight the practicality of having two USB ports, especially on trips where only one socket is accessible. There is also feedback that the adapter can be a bit bulky, and that the internal “sliders” for selecting ports can feel stiff at first, though performance holds up after repeated use. Overall, review themes point to reliable everyday travel use, with the biggest caveat being that the adapter is meant for plug conversion only, not voltage conversion.
Who this travel adapter is for
This adapter is a practical choice if you are traveling to Denmark or any destination with Type K outlet spacing and you want one compact piece to handle both standard chargers and USB charging.
- Best for: US travelers bringing dual-voltage chargers for phones, tablets, cameras, and laptops, and wanting to charge two USB devices at once.
- Great for grounded setups: Reviews suggest it can support a stable, grounded-style connection where your specific charger and outlet wiring setup require it.
- Ideal for short trips: Its small footprint makes it easier to pack compared to carrying separate USB chargers and a basic adapter.
Key specs to check before you buy
1) Plug type and outlet compatibility (Type K)
This model is intended for the Denmark-style Type K outlet. Make sure your destination uses Type K, since plug standards vary widely across Europe and the world.
2) It is not a voltage converter
Use it for devices that are already compatible with the local power system, particularly dual-voltage equipment. If your device requires a step-down voltage (for example, many single-voltage appliances from the US), this adapter alone will not make it safe to use.
Look for charger labels that indicate dual-voltage support (commonly “100-240V” style wording). Phone and many laptop chargers are often dual-voltage, but not all electronics are.
3) Power capacity and USB charging
The adapter is rated for up to 10A at 250V. It includes dual USB charging with up to 2.4A total output, designed for typical phone, iPhone, iPad, tablet, and accessory charging needs.
Pros and cons in real-world use
Pros: why it makes sense for travelers
- Secure connection: Multiple reviews mention that chargers stay firmly seated in the outlet slots.
- Less gear at the wall: Two USB ports reduce the need for separate USB wall blocks.
- More flexible setup: You can plug in a standard charger while also charging another USB device.
- Travel-friendly size: It packs small enough to fit into a carry-on or toiletry bag.
Cons: the tradeoffs to be aware of
- Bulky relative to simple adapters: Some outlet designs with closely packed sockets can make the adapter harder to use alongside other plugs.
- USB access can be tight: Review feedback suggests the two USB ports are close together, which can make inserting or removing a single charger a bit less convenient than larger-spacing designs.
- Compatibility depends on dual-voltage gear: If you own any single-voltage device, you will need a true voltage converter instead.
How it compares to simpler travel adapters
If you are only trying to convert a US plug to a Denmark Type K outlet, a basic plug adapter might be cheaper and slimmer. However, the dual USB approach here is often more convenient when:
- you have fewer accessible outlets in your lodging,
- you want to charge two devices at the same time, or
- you want to travel with fewer wall chargers.
Choose this type of adapter when you expect to rely on USB charging frequently. Choose a simpler plug adapter when you already pack a dedicated USB charger setup, and you care most about minimizing bulk.
Verdict
The OREI Denmark Travel Plug Adapter with Dual USB is a solid travel-friendly option for Denmark Type K outlet setups, especially if your gear is dual-voltage and you want the convenience of charging two USB devices at once. The main buying caveat is that it does not function as a voltage converter, and its size can be a tradeoff in tight outlet layouts.
