A universal power plug adapter is one of those travel accessories you don't really appreciate until you need one.
You arrive at your hotel after a long flight, take out your phone charger, and then realize the outlet doesn't accept the plug you've been using at home.
I've been in situations like this while traveling, and it's one of those small problems that can become surprisingly annoying.
That's why I prefer carrying a universal travel adapter instead of buying a different plug adapter for every country I visit.
And these days, I don't want a basic adapter that only changes the shape of the plug. Since most of my electronics use USB-C, I'd rather have a travel adapter that also works as a fast USB-C charger.
For travelers carrying a laptop, phone, tablet, camera, earbuds, and other electronics, having one device that can handle several of them can make your packing much easier.
After looking at the options available in the US market, one model that caught my attention is the Insignia 70W Travel Adapter from Best Buy.
It combines universal plug compatibility with 70W USB-C charging, multiple USB ports, and two AC outlets, making it a useful all-in-one option for international travelers.
My Pick: Insignia 70W Travel Adapter
If you're looking for a universal travel adapter with fast USB-C charging, the Insignia 70W Travel Adapter is one I'd put on my shortlist.
Insignia is Best Buy's house brand, and this particular model is designed specifically for international travel.
At the time of writing, Best Buy lists it at $39.99. Prices can change, so I'd check the current listing before purchasing.

For someone who travels internationally with several electronic devices, that's a pretty useful combination.
Why USB-C Matters for Travel
A few years ago, I would have been happy with a travel adapter that simply gave me access to a foreign wall outlet.
That's not enough for me anymore.
USB-C has become the charging standard for so many devices.
You might have:
- A USB-C smartphone
- A MacBook
- An iPad
- Wireless earbuds
- A power bank
- A camera
- A smartwatch
- Other USB-C accessories
That's where a product like the Insignia 70W becomes useful.
It has three USB-C ports and two USB-A ports, so you can charge several smaller devices from the same wall outlet.
For me, that's a much better travel setup than carrying a collection of individual chargers.
Is 70W Enough to Charge a Laptop?
For many travelers, yes.
The Insignia adapter supports up to 70W of USB-C charging, which is enough for many lightweight laptops, tablets, and phones.
That makes it particularly interesting if you work while traveling.
For example, if you're traveling with a MacBook Air or another relatively efficient USB-C laptop, you may be able to leave the original charging brick at home and use the travel adapter instead.
However, you shouldn't assume that every laptop will charge at its maximum speed.
Some larger laptops require significantly more power.
If your laptop normally comes with a 100W, 140W, or higher charger, a 70W travel adapter may not provide the same charging performance.
So check your laptop's charging requirements before replacing its original charger.
You Can Charge Multiple Devices at Once
This is probably my favorite part of having a multi-port travel adapter.
Imagine arriving at your hotel with:
Laptop + phone + smartwatch + earbuds + camera
With a normal setup, you might need several chargers and multiple outlets.
With a multi-port travel adapter, you can potentially plug most of them into the same device.
The Insignia model gives you:
- 3 USB-C ports
- 2 USB-A ports
- 2 AC outlets
Of course, the power is shared when multiple devices are charging. The 70W figure doesn't mean every USB-C port can independently deliver 70W at the same time.
Still, having several ports available can make a big difference when you're staying in a hotel room with only a couple of convenient outlets.
Universal Plug Compatibility
The whole point of buying a universal travel adapter is being able to use it in multiple countries.
The Insignia 70W model uses four plug configurations covering the United States, European Union, United Kingdom, and Australia. Best Buy says the adapter is compatible with outlets in more than 200 countries and territories.
That's useful if you're taking a multi-country trip.
For example, you might start your trip in the United States, continue to Europe, then visit the UK or Australia later.
Instead of buying a new plug adapter for each destination, you can take one universal adapter with you.
Just remember that "universal" doesn't mean you should blindly assume it works with every outlet in every country.
Check your destination before traveling.
One Important Warning: It Does Not Convert Voltage
This is something I wish more travelers understood.
A plug adapter is not automatically a voltage converter.
The Insignia 70W Travel Adapter changes the plug configuration so your charger can connect to the local outlet, but it does not convert 220–240V electricity into 110–120V electricity. Best Buy specifically states that it does not convert voltage.
This is extremely important for US travelers.
The United States commonly uses 120V electricity, while many countries use around 220–240V.
Fortunately, most modern electronics chargers are designed to accept a broad input range.
Check the label on your charger.
If it says something like:
Input: 100–240V, 50/60Hz
then the charger is designed to work with different electrical systems.
But you should never assume this.
Check the actual specifications of your device before plugging it into a foreign outlet.
Don't Confuse a Travel Adapter With a Travel Converter
These two products are easy to confuse.
A travel adapter changes the physical plug configuration.
A voltage converter changes the electrical voltage.
They're different things.
If you're taking a US-only appliance that requires 120V into a country with 220–240V electricity, you may need an appropriate voltage converter.
The Insignia travel adapter is not designed to perform that function.
For phones, laptops, tablets, and other modern electronics, the charger itself often handles different voltages. But again, check before you travel.
What About Hair Dryers and Other Appliances?
I'd be particularly careful with appliances.
Travelers sometimes see a universal adapter and assume they can plug absolutely anything into it.
That's not how it works.
High-power appliances such as:
- Hair dryers
- Curling irons
- Straighteners
- Electric kettles
- Clothes irons
- Heaters
The Insignia adapter's USB charging ports are designed for USB devices, while the AC outlets are intended for compatible devices within the adapter's electrical ratings. Its setup guide also emphasizes checking voltage compatibility before use.
So before plugging in an appliance, check both the appliance's voltage requirements and the adapter's specifications.
Why I Like GaN Chargers for Travel
Another feature worth paying attention to is GaN, or gallium nitride.
GaN technology has become increasingly common in compact high-power chargers.
For travelers, the main advantage is simple: you can get a lot of charging power without necessarily carrying a huge charging brick.
The Insignia 70W travel adapter uses GaN III technology.
That's useful when you're trying to keep your luggage compact.
I don't want my charging setup taking up half of my backpack.
The whole point of good travel gear is to make things simpler.
How Many Devices Can You Charge?
The Insignia 70W Travel Adapter has:
USB-C
3 USB-C ports
These are the ports I'd prioritize for newer devices.
USB-A
2 USB-A ports
These are useful if you still have older cables or accessories.
AC outlets
2 AC outlets
These let you connect devices that still need a traditional wall plug.
So you could potentially have a setup like this:
USB-C: Laptop USB-C: Phone USB-C: Tablet USB-A: Earbuds USB-A: Smartwatch AC outlet: Camera charger AC outlet: Another compatible device
You probably won't need all seven at once, but having the flexibility is useful.
Retractable Plug Pins Make It Easier to Pack
Small design details matter when you're traveling.
The Insignia adapter has retractable plug pins, which means the international plug components can fold back into the adapter when you're not using them.
That's useful because exposed plug pins can take up awkward space in your bag.
With the pins retracted, the adapter is easier to pack alongside your other electronics.
It's a small feature, but it's exactly the kind of thing I appreciate in travel gear.
What Should You Look For in a Universal Travel Adapter?
If you're shopping for a universal travel adapter yourself, I wouldn't just look at the number of ports.
Here are the specifications I'd check.
1. USB-C Power Delivery
Don't assume that every USB-C port supports fast charging.
Look for USB-C PD and check the actual wattage.
For someone carrying a laptop, I'd look at roughly 65W or higher.
2. International Plug Types
Check which plug configurations are included.
At minimum, make sure the adapter supports the destinations you're visiting.
3. Number of USB Ports
Think about how many devices you normally carry.
If you're traveling with five or six electronics, multiple USB ports can be extremely useful.
4. Total Power Output
Don't just look at the highest number printed on the box.
Check how the power is distributed when multiple ports are being used.
5. Voltage Compatibility
This is extremely important.
Remember:
Travel adapter ≠ voltage converter.
6. Size and Weight
You're putting this in your luggage.
A charger that weighs a ton isn't particularly useful just because it has 15 ports.
7. Safety Features
Look for appropriate protections such as fuse protection, temperature management, and other safety features.
Is the Insignia 70W Travel Adapter Worth It?
For a US traveler who wants a single travel adapter for international trips, I think the feature set makes sense.
You're getting:
- 70W USB charging
- 3 USB-C ports
- 2 USB-A ports
- 2 AC outlets
- US/EU/UK/Australia plug configurations
- GaN charging technology
- Retractable plugs
- Broad international compatibility
The main thing I'd consider before buying is whether you actually need that many ports.
If you only travel with a phone and a pair of earbuds, a smaller adapter might make more sense.
But if you're carrying a laptop and several other electronics, the additional ports can be genuinely useful.
An Alternative: TESSAN 65W Universal Travel Adapter
Another option worth looking at is the TESSAN 65W Universal Travel Adapter.
Best Buy currently lists a TESSAN model with four USB-C ports and one USB-A port, along with a universal AC outlet. It supports Type C, G, A, and I plug configurations and is designed for use across many international destinations.
The model I found is currently listed around $37.99 at Best Buy, although pricing can change.

It's worth comparing the port configuration with your own needs.
If you mostly use USB-C devices, having four USB-C ports could be more useful than having additional USB-A ports.
Another Option: Epicka Pulse Duo 65W
Epicka's Pulse Duo 65W Universal Travel Adapter is another model available through Best Buy.
It has two USB-C ports, two USB-A ports, a universal AC outlet, and a US AC outlet. Its primary USB-C port can provide up to 65W, while the manufacturer specifies lower output when multiple USB-C ports are used simultaneously.
Best Buy currently lists it at $49.99.

Again, I wouldn't choose purely based on the highest wattage number.
Look at the complete port configuration and decide what fits your travel setup.
My Ideal Travel Charging Setup
If I were packing for a long international trip, I'd try to keep my charging setup simple.
Something like:
Universal travel adapter + USB-C laptop cable + USB-C phone cable + one extra cable for older accessories.
That's it.
Instead of packing several charging bricks, I can use one main adapter and connect everything to it.
This becomes even more useful if you're working remotely.
When you're moving between hotels, hostels, apartments, and other accommodations, fewer accessories mean fewer things to lose.
And trust me, losing a tiny charging brick or adapter while traveling is much more annoying than it sounds.
Where Should You Buy It?
For a US-focused audience, I'd start with major US retailers rather than buying an unknown adapter from a random marketplace seller.
For the Insignia model, Best Buy is the obvious place to check because Insignia is a Best Buy brand and the product is sold directly by Best Buy.
Buy the Insignia 70W Travel Adapter from Best Buy
You can also compare current Amazon US listings before buying, particularly if you prefer Amazon for shipping and returns.
I'd just make sure you're looking at the exact model and specifications, rather than buying based only on a product title such as "Universal Travel Adapter."
Final Thoughts
A universal travel adapter is one of those things that can make international travel noticeably easier.
But I wouldn't buy a basic adapter anymore.
If I'm going to carry one, I'd rather have something that also works as a proper multi-port USB-C charger.
For US travelers, the Insignia 70W Travel Adapter is an interesting option because it combines international plug compatibility with three USB-C ports, two USB-A ports, two AC outlets, and up to 70W of USB charging in one device.
The biggest thing to remember is that it doesn't convert voltage. Always check whether your electronics support the voltage used at your destination before plugging them in.
If you're carrying a laptop, phone, tablet, camera, earbuds, and other electronics, a multi-port adapter can also save quite a bit of space in your luggage.
For me, that's ultimately what makes a good travel accessory.
It doesn't need to be complicated.
It just needs to do several jobs well and save me from carrying unnecessary stuff.
And a universal travel adapter with fast USB-C charging does exactly that.
