Voltage, customs, warranty & freight forwarders explained
Buying electronics from the USA can feel like discovering a cheat code. Lower prices, bigger product ranges, and huge sale events that never quite make it overseas are hard to ignore.
Still, many shoppers in the UK, Western Europe, the Middle East, India, Southeast Asia, Australia, Canada, and fast-growing markets like South Africa, Nigeria, and Brazil hesitate before clicking buy.
That hesitation makes sense. The risks aren’t always obvious, and when something goes wrong, it can get expensive fast.
This guide breaks down what really happens when you buy electronics from the USA. If you’re unfamiliar with the overall process, Stackry’s How It Works page explains each step from delivery to international shipping. It explains the common mistakes, the hidden costs, and how people safely import tech every day without unpleasant surprises.
Most people start with the same question: can I buy electronics from the USA and use them internationally?
The answer is yes, but only if you understand what you’re trading off.
The experience of buying electronics from the USA depends heavily on what you buy and where you live.
In practice, shipping is rarely the problem. Issues usually come from voltage differences, wireless compatibility, customs charges, or assuming warranties work globally when they often don’t.
The biggest mistakes happen when buyers get distracted by deals and skip the checks. Specs don’t get verified, taxes get underestimated, and complex categories like large appliances get treated the same way as phones or laptops. The key thing to remember is simple: not all electronics behave the same once they leave the US market.
The US uses 110 to 120V power, while much of the rest of the world runs on 220 to 240V. If a device isn’t dual voltage, plugging it in abroad can permanently damage it.
If you don’t see 100 to 240V clearly listed on the product or charger, a 110V device won’t safely run on a 220V system. There are some quick fixes: step-down transformers can make 120V-only devices work, but for high-wattage electronics they’re often bulky, inefficient, and not worth the hassle.
Similarly, voltage converters can be fine for small, low-power items, but once heating elements or motors are involved, things get risky. That’s why US appliances and international power systems rarely mix well.
In short: laptops, phones, tablets, cameras, and gaming consoles are almost always dual voltage and safe. Devices containing lithium batteries are subject to additional shipping rules, which are covered in more detail in this guide on shipping lithium-ion batteries from the USA. Kitchen appliances, printers, and motor-driven devices are where long-term use becomes questionable.

One of the most common questions is whether an iPhone from the US will work in the UK or elsewhere. Power usually isn’t the issue, but wireless compatibility is.
US phone compatibility outside the USA varies by model. Some U.S. phones don’t support all the LTE or 5G bands used internationally; and while buying unlocked phones from the USA helps, but it doesn’t guarantee compatibility. You still need to match your carrier’s supported bands with the phone’s specs. Android phones can add extra friction through region-specific firmware or software restrictions. In fact, most problems using US phones internationally come down to missing bands, rather than faulty or unsuitable hardware.
Smart home devices introduce yet another layer of complexity. Some rely on US-only apps, region-locked features, or accounts tied to the American app store, which can limit how they work once you’re abroad.
It’s no surprise that the checkout price is rarely the final price when importing electronics from the USA.
However, these extras can add up, making what looked like a great deal become an expensive mistake.
Every country applies its own customs rules, but some patterns are consistent. Many countries charge VAT on arrival, and some apply duty depending on the category. For example, the UK has a £135 duty-free threshold and the EU effectively has none, while countries like the UAE offer higher thresholds.
These so-called “hidden” fees usually aren’t hidden at all; buyers just need to check their local import rules in advance. Customs delays often happen when invoices are missing or values are misdeclared, and when electronics get stuck in customs, the first thing officials ask for is proof of purchase. Making sure that you have all the right paperwork in the right place and you’ve paid the correct taxes and duties will make the process much easier, not to mention quicker and less stressful.
It’s important to note that many U.S. electronics warranties only apply within the USA.
Even if the brand exists in your country, the manufacturer warranty may not. What’s more, returning electronics bought in the USA is usually slow and expensive. In most cases, you’ll need to ship the item back to the US at your own cost.
That doesn’t mean buying U.S. electronics is unsafe. It just means that it’s more important than ever to make sure that you’re buying a compatible product, and that you allow for limited warranty protection when you consider the cost savings of buying your electronics from the USA.
For many international shoppers, the real challenge comes when trying to get the package shipped, with some U.S. stores not shipping outside of the USA or charging large amounts for international delivery. Stackry members are provided a unique shipping address in America, so they can shop from American stores that don’t offer international delivery.
To make the shipping process simple and safe, reputable forwarders like Stackry offer package photos, repacking to reduce size and weight, and consolidation so you can ship multiple items together. This lowers shipping costs and reduces damage risk; if you’re unsure about processes, our experienced team will be able to offer advice.
Although bagging that bargain from a U.S. store may seem irresistible at the time, it can be a false economy, depending on the product, the sale, and your country’s import rules.
Black Friday and Cyber Monday deals can be worth importing, especially for laptops, phones, PC components, and accessories. However, don’t be blinded by the discounts: avoid disappointment (and unexpected costs) by checking voltage, wireless bands, or customs costs before you proceed to checkout. .
In short: buying electronics from the USA is worth it when the item is dual voltage, globally compatible, compact, and still cheaper after VAT.
However, there’s no simple answer because buying internationally will almost always involve trade-offs, the nature of which will depend on your location, the device type, and how much risk you’re willing to accept. That’s why people keep searching beyond surface-level explanations.
Buying electronics from overseas can seem daunting. However, once you understand voltage, wireless compatibility, customs costs, and how freight forwarding works, buying electronics from the USA becomes predictable rather than risky. Most problems are avoidable, and most modern tech is already designed to work globally if you check the details before you buy.
