How We Put It to the Test

To get real answers, we ran a series of tests using different iPhone chargers, measuring charging speed, power consistency, and battery impact. The goal? Find out whether an iPhone charger can actually keep up with the Switch’s power demands.

We tested multiple Apple chargers:

• 5W iPhone Charger (the classic brick) – The tiny charger bundled with older iPhones.
• 12W iPad Charger – A step up, but is it enough?
• 20W USB-C Charger – The new standard for fast-charging iPhones.
• 30W USB-C Charger – Apple’s more powerful laptop-compatible adapter.

Each charger was tested under different conditions:

1. Charging While the Switch Was Turned Off – Would it at least trickle charge?
2. Charging in Sleep Mode – Could it hold a charge while idle?
3. Charging While Playing Games – The ultimate test: power in, power out.

What Happened When We Plugged Them In?

• The 5W charger? Absolutely useless. It barely registered as a power source.
• The 12W charger? It charged… but painfully slow.
• The 20W charger? Surprisingly, it worked—but not at full speed.
• The 30W charger? The best of the bunch, but still not as fast as Nintendo’s official adapter.

What About Heat and Battery Safety?

Heat is a silent killer for batteries, and using an underpowered or inconsistent charger can cause unwanted thermal buildup. During testing, we monitored temperature levels. The 5W and 12W chargers ran cool (because they barely charged), while the 20W and 30W models heated up slightly but stayed within safe limits.

So, can an iPhone charger charge a Switch? Yes, but not all chargers are equal. Some barely work, others charge slowly, and only a few provide a decent alternative. But is it worth the risk of slower speeds and potential battery strain? Let’s break it down further.

Is It Safe to Charge a Switch with an iPhone Charger?

The idea seems harmless. You grab your iPhone charger, plug in your Nintendo Switch, and hope for the best. But behind that simple act, there’s a complex interaction of voltages, amperages, and charging protocols at play. The wrong pairing could mean sluggish charging—or worse, potential battery degradation over time.

Most people assume that as long as the plug fits, the charger is safe. That’s a dangerous misconception. Every device has specific power needs, and mismatched chargers can cause overheating, inefficient charging, and long-term battery wear. So, is an iPhone charger a viable backup, or is it slowly harming your Switch every time you plug it in?

The KYT 35W Mini Charger is compact, powerful, and designed for high-speed charging. Whether you need to charge your iPhone, Nintendo Switch, or other USB-C devices, this charger delivers efficient, reliable power without the bulk.

The Science of Safe Charging

Every charger delivers power at different speeds, dictated by wattage, voltage, and amperage. The official Nintendo Switch adapter outputs 15V/2.6A (39W), ensuring fast and safe charging. Meanwhile, iPhone chargers range from 5W to 30W, and not all of them support USB-C Power Delivery (PD)—a crucial factor in safely charging a Switch.

Using an underpowered charger means your Switch may take twice as long to charge—or worse, it may not charge at all while gaming. An overpowered or incompatible charger, on the other hand, could cause excessive heat buildup, straining internal components and reducing battery lifespan.

Potential Risks of Using an iPhone Charger for a Switch

1. Undercharging: A low-watt charger might keep your Switch from dying, but it won’t charge efficiently. If the charger can’t deliver 15V, the Switch will default to a trickle charge—or outright reject the power source.
2. Overheating: Incompatible chargers can cause temperature spikes, especially when using cheap or uncertified cables. Heat is one of the biggest culprits behind battery degradation.
3. Battery Stress: Lithium-ion batteries degrade faster when subjected to inconsistent power delivery. The wrong charger can cause voltage fluctuations that put stress on the battery over time.
4. Power Drain While Gaming: Some iPhone chargers don’t deliver enough power to keep up with in-game power consumption, meaning your Switch could still drain while plugged in.

The Verdict: Is It Worth the Risk?

Not all iPhone chargers are created equal. While higher-wattage USB-C models (such as Apple’s 20W or 30W adapters) may offer passable charging speeds, they still don’t match the efficiency of the official Nintendo charger. Older 5W and 12W iPhone chargers? Practically useless.

In an emergency, a high-watt USB-C iPhone charger might work, but for long-term battery health, using a dedicated PD-certified charger is the safest bet. If you want reliable, high-speed charging that works across devices, it’s worth investing in the right gear.

The Best Alternatives to Charging Your Switch

The dreaded low-battery warning appears. Your Nintendo Switch is gasping for power, and the official charger is nowhere in sight. Frantic, you rummage through your tech drawer. A tangle of cables and adapters stares back. Among them? An iPhone charger.

You pause. It has a USB-C cable. It works with your iPad. But will it work with your Switch? Or worse—could it cause slow charging, overheating, or battery damage? The answer isn’t as straightforward as it seems. Not all chargers are created equal, and using the wrong one can leave your Switch struggling to power up—or drain faster than it charges.

   • Double-check that they provide 15V output for full compatibility.

Final Thoughts: Don’t Risk It with an Underpowered Charger

If you’re in a pinch, a high-wattage USB-C iPhone charger (like Apple’s 30W adapter) may work—but it’s not ideal. Using an underpowered charger can result in slow charging, overheating, and potential battery wear.

For the safest and fastest charging, stick with USB-C PD-certified adapters. The right charger makes all the difference—keeping your Switch powered up, protected, and always ready for your next gaming session.

Can a Switch Charge an iPhone? Reverse Charging Explained

Imagine this: You’re out, your iPhone battery is circling the drain, and there’s no power outlet in sight. But in your bag? A fully charged Nintendo Switch. A wild thought crosses your mind—could my Switch save my iPhone? It has a USB-C port, after all. And if an iPhone charger can (sort of) charge a Switch, could the process work in reverse?

It sounds futuristic, but reverse charging—where one device acts as a power source for another—is becoming more common. Many modern laptops and tablets with USB-C Power Delivery (PD) can now charge smaller devices like smartphones. But does the Nintendo Switch have that ability? Could it function as an emergency power bank for an iPhone? Or is this just another tech myth that doesn’t hold up in reality?

Does the Nintendo Switch Support Reverse Charging?

The Nintendo Switch is powered by USB-C, which is known for its versatility. Some USB-C devices, like MacBooks and Android phones, allow reverse charging, meaning they can send power outward instead of just receiving it.

However, the Switch operates differently. Nintendo designed it primarily as a power-hungry gaming console, meaning it’s optimized for taking in power, not distributing it. While the USB-C port might physically support charging, the system firmware controls whether or not energy can flow outward.

So, what happens when you plug an iPhone into a Switch using a USB-C to Lightning cable?

We Tested Reverse Charging – Here’s What Happened

We conducted a simple test:

1. Connected an iPhone to a Nintendo Switch using a USB-C to Lightning cable.
2. Monitored power flow using a digital meter.
3. Tested different battery levels to see if it made a difference.

The results? The iPhone did not charge from the Switch. Instead, the opposite happened—the Switch began draining faster, trying to pull power from the iPhone instead.

Why? The Switch lacks the firmware and hardware to deliver power through USB-C. Unlike some laptops that support bi-directional charging, the Switch is a one-way street—it only receives power, never gives it.

Is There a Workaround?

Yes, but it’s not ideal. The only way to charge an iPhone using the Switch is by connecting a power bank or external adapter to the Switch’s USB-C port and then running a cable to the iPhone. Essentially, using the Switch as a middleman. But at that point, you’re better off carrying a dedicated USB-C power bank.

Final Verdict: Can the Switch Charge an iPhone?

No. While the USB-C port might seem capable of reverse charging, Nintendo has restricted power output. If you’re looking for an emergency power source for your iPhone, you’ll need a proper power bank or multi-device charger. The Switch is great for gaming—but when it comes to charging other devices, it’s a hard no.

Myths and Misconceptions About Charging a Switch

A dead Nintendo Switch and a missing charger—every gamer’s worst nightmare. But wait, there’s an iPhone charger right there. It fits. It connects. That should work, right?

Or will it charge at a snail’s pace? Overheat? Damage the battery?

The internet is full of conflicting information. Some claim any USB-C charger will work, while others warn that using the wrong one will fry your device. So what’s the truth? Can you really swap out Nintendo’s official adapter for an iPhone charger without consequences?

It’s time to separate fact from fiction and bust the biggest myths about charging a Nintendo Switch.

USB-C might be universal, but charging standards aren’t. While many devices share the same port, not all chargers provide the correct voltage, wattage, and amperage needed for a Nintendo Switch.

Nintendo’s official charger delivers 15V/2.6A (39W)—far more than most iPhone chargers. A weak power supply might trickle charge your Switch, but it won’t be enough to sustain gameplay.

Myth #2: “Low-Watt Chargers Are Completely Safe”

A lower-wattage charger may seem harmless, but slow charging isn’t always safe charging. Here’s why:

1. Inconsistent power delivery can cause the Switch to pull energy inefficiently, leading to excess heat.
2. Extended charge times increase the number of battery cycles, reducing lifespan over time.
3. Underpowered charging during gameplay can result in battery drain while plugged in, making the charger useless.

Myth #3: “Fast Charging Hurts the Battery”

Some believe that fast chargers wear out batteries faster—but that’s not how modern lithium-ion technology works. The Switch, like most devices, regulates power intake and won’t accept more than it can safely handle.

Using a certified USB-C PD charger that matches the Switch’s power profile is actually better for battery health than underpowered alternatives.

Final Verdict: What Should You Use?

An iPhone charger might work in an emergency, but it’s not a long-term solution. Slow charging, inconsistent power, and potential heat issues make it less than ideal. If you need a reliable alternative, look for USB-C PD chargers with at least 30W output.

Charging myths can be confusing, but one thing is clear—using the right charger matters. Don’t risk your Switch’s performance and battery life with a weak power source. Invest in safe, efficient charging and keep your gaming uninterrupted.

When an iPhone Charger Is Okay for the Switch

If you’re in a pinch, an iPhone charger with USB-C Power Delivery (PD)—like the 20W or 30W adapter—might be enough to slowly charge the Switch while idle. It’s not ideal, but it can keep the battery from completely dying.

But if you plan to charge while gaming, forget it. The power draw of the Switch under load is often higher than what a standard iPhone charger can deliver. Instead of charging, the battery may continue draining—just slightly slower than before.

When You Should Avoid Using an iPhone Charger

1. If It’s a 5W or 12W Adapter – Older iPhone chargers lack the voltage and amperage needed for the Switch. Plug one in, and you’ll barely see the battery percentage budge.
2. If You’re Gaming While Charging – The Switch can use up to 18W of power while in use. A low-wattage charger won’t keep up, leading to slow depletion even when plugged in.
3. If You Care About Long-Term Battery Health – Lithium-ion batteries degrade faster with inconsistent or underpowered charging. Using the wrong adapter repeatedly can cause unnecessary strain over time.

The Smarter Alternative for Reliable Charging

Instead of rolling the dice with an iPhone charger, a USB-C PD charger with at least 30W output is the best alternative. This ensures the Switch gets stable power delivery, charges at a reasonable speed, and remains powered during gameplay.

So, should you use an iPhone charger for your Switch? In an emergency, maybe. As a long-term solution? Absolutely not. Invest in a fast, safe charger designed to handle your Switch’s power needs. Your battery—and your gaming experience—will thank you.

Conclusion and Best Charging Practices

The verdict is clear: while an iPhone charger can charge a Nintendo Switch under the right conditions, it’s far from the ideal solution. If you’re in a pinch, a high-wattage USB-C iPhone charger (like Apple’s 20W or 30W adapter) might keep your Switch alive—but it won’t provide the fast, stable charging the device was designed for.

Relying on a low-power charger is like filling a gas tank with a straw. It may work, but painfully slow and inefficient. Worse, if the charger lacks USB-C Power Delivery (PD), your Switch may refuse to charge entirely—or drain faster than it replenishes. And don’t forget the long-term impact. Inconsistent voltage and amperage can stress the battery, leading to premature degradation.
